trendiness but that's up to you and this is just my opinion. hello and welcome to this month's special edition of technology updates where we look to the skies to see the peak of russian innovation on today's show because it's a glimpse of bush's latest stealth fighter. we find out that's a cross between a battery and a combustion engine isn't just a load of. up and down the ground we learn about the mysterious night. but first let's take a look at some of the highlights of this month's show. the international aviation

space show all marks is the highlights of the calendar not just for aviation enthusiasts but for anyone who enjoys a good day out there show started off in one thousand nine hundred ninety three when the focus was mainly on entertainment since then it's evolved into an important business event given the high flyers of the aviation industry a chance to sell their wares this year marks smashed its own attendance record with over one hundred fifty thousand people braving the elements to visit the event in just one day business also proved with companies signing agreements and contracts with twenty one point two billion dollars which is significantly more than last time believing this has wider implications than just the aviation industry. the aircraft manufacturing industry always drives innovation throughout the world because to be competitive in this industry you have to excel in a number of different areas that's why this industry receives so much investment that some people. that for every rube invested in new technologies for

manufacturing you get a return of seven rubles because of the positive effect this provides for all the other industries. i'm sure that return on investment was the last thing on people's mind when the flight program started. the demonstrations give money fighters the opportunity to show off exactly what they can do this is especially important for kraft is the perfect place for defense organizations to cooperate with. the most efficient. machine operation. is testament to the. difficult condition. isn't just to selling military hardware. to simple helicopter builds on the legacy piece.

and is about thirty percent cheaper than anything else in the market under peaceful international cooperation doesn't company russian helicopters presented the first prototype of his luxurious k. sixty two passenger helicopter the helicopter is fitted with french engines for marking the first time the company has teamed up with a european partner is still undergoing tests but the company is order received a number of orders. would be complete without a display from the. teams that have been showing off their precise flying skills together over ten years only ones with some slick moves see the grace and agility of passenger jets as they perform seemingly impossible. to cure anyone of their fear of flying you'd find many people willing to take.

that's taking place outside as well as providing shelter for. the pavilions also gave visits is of. the high technology that keeps the skies. opportunity to show the future of aviation with. the medium range to hit the market in two thousand and seventeen it will be built with confidence and materials and economic engines which make you greener. probably makes it more comfortable for those inside. the russian civil aircraft to be built around the open architecture principle this means that components and systems can simply be swapped out if they need repairing or grading. the company demonstrated the simulator for the aircraft the fixed space devices emulates the controls and avionics of the m twenty one can also be used to test. to the plane. it was designed by katie company

and dutch company sim industries and will be used for a pilot training program. and talking of training pilots. is capable of simulating the feel of flying for and fifth generation jets it is also extremely difficult to get into a flat spin if the rookie pilot somehow money. take over and save the day is even capable of landing on. it's not surprising it was voted the best train at the paris air show this year. isn't just a place to showcase aircraft and one of the highlights of the show this year was this prototype. is part of a next generation space ship that will serve the international space station and possibly even go beyond the space. ships. for the cosmonauts inside. this is such a piece of technology there are only two countries in the world that can. of

producing it and even they do this only once every fifteen years we do our best to keep all the equipment here as compact as possible to leave more room for the cosmonauts so they can stand here without having to say. this is important for example similar vehicles produced in the us don't have enough room to stand up and . this is a multipurpose vehicle they can be used both for taking cosmonauts into orbit and for traveling to the moon. all of the aircraft on the space for everyone to see up close with the exception of one because the stealthy design of this next jets makes it very hard. the park forty fifty is bush's fifth generation fighter the supersonic jet made its second appearance at the next air show but this was the first time that the media were able to get a slightly closer look the aircraft is radically different from its predecessors as well as being faster more intelligent and maneuverable scientists have worked hard

to make it as stealthy as possible the design bureau which is part of the united aircraft corporation works very closely with the various research centers of the russian academy of sciences for example we've been working together on this fifth generation fighter jets. and i believe to something that is on a par with the best models in this class worldwide the part. of the fusion between theoretical science and practical application and he's one of only a few fifth generation finds his in the world. we've got competition from china and japan has also announced that it's going to develop its own fifth generation fighter but so far neither china nor japan have presented any working prototypes of their aircraft so the only objects that can be compared to the t fifty is the f. twenty two generally speaking these two planes have a lot in common but only time will show in what way one is better than the other the park. the park is

a stealth aircraft particular attention has been paid to the leading edge of the wings which has been staggered the weapons bays which have been concealed the jet turbine blades which have been covered and the air intake which is shaped and those are just the bits we can see with the naked eye the plane must also be shielded from external interference whilst also emitting signals of its own without being detected with military planes being so well protected against electronic interference i bet the pilots don't have to turn off their mobile phones when taking off and landing military conflicts often aren't as a catalyst for scientific advancement this is especially true of the radar which first proved itself as a viable means of defense at the end of the second world war since then radar and plane developers have been trying to outmaneuver each other to get the upper hand on the battlefield a simple radar system is made up of a transmitter under receiver the transmitted image radio waves which bounce off an object such as this aircraft and are picked up by the receiver unit you radars control to be split into two types detection and search and targeting radar

detection citrate dusk on a wide area once every fifteen to thirty seconds and operates on long radio waves they are used for early warning systems and surveillance targeting very docile knew the hunt much narrow area several times a second and a use for missile guidance systems and targets tracking but it's not all doom and gloom for the actual. number of ways. the small. birds disappear altogether but it's not as easy as you might think a pilot can hold the ground's high the plane to naturally. this makes fine much more dangerous the shape of the plane can also be discussed on the radio waves in any direction apart from but the receiver considered you seem unable to listen and speak however there is another way is not so simple as just changing the color of the aircraft because it has to be closely redesigned on a black your level oh and pay attention a little here is the. the company not only conducts research into composite

materials and nano coatings but also focuses on the real life application in the aviation industry compas that material such as carbon fiber often numerous benefits over those traditionally used in aircraft and that's why the pot is full of them to make an aircraft of carbon fiber a mold must first be made the company uses milling machines carefully to cook the mold of what it is then finished by hand before being sent on to the next stage play is a fiberglass and carbon fiber placed on the mold which is then sealed in a vacuum she was attached to the bag. and infused the mold with the seal is constantly check to make sure there are no imperfections in the finished product. about seventy or eighty percent of the fighter jets body is made of composite material namely carbon fiber without working on modifying the composite materials with carbon. which will help further improve the jury ability of the

components. at speeds of over one thousand kilometers per hour it's all to do for. the plane to move as a. carbon fiber composite components also significantly decrease the visibility on the plane making it. and russia has been quite successful in supplying this technology. as well as manufacturing composites components the company also specializes in producing multi-functional nano colton's a number of institutes around russia have been developing nano coatings for. was unfortunately they didn't meet the high standards required for the latest jets. must protect the pilot from electromagnetic radiation the song should not contribute to the plane's radar profile. must of course be as transparent as

possible. to develop one that meets all of these requirements. and is applied in a special vacuum chamber. coating is made up of tin oxide and gold and is applied in a process known as sputtering layers of tin oxide and gold are applied in turns using an ionization process to build up a coating just stand nine millimeters thick but some afraid that's all we can say the exact makeup of the coaching is a secret. makes the surface forty to sixty percent less detectable by radar. in five to six times more resistant to abrasion which. this provides a huge advantage in the field. also much more transparent which reduces reflection from inside the cockpit enabling the pilot to see the runway lights more clearly. fortunately we weren't allowed to film how the coatings are applied to the other

aircraft components either. dissimilar to painting a large civil airliner. contain federal magnetic nano particles which are known for their radar absorbent properties just applied evenly all over the plane. different radar. different parts of the plane invariant thicknesses. this attention to microscopic detail can give potentially huge benefits in the flight and stealth characteristics of the aircraft. design a fourth generation fighter using almost fifty generation technology. the size of a football the t fifty shows as an object the size of a tennis ball so you can see the progress that we've made. the composition components have been produced on a nano coatings applied their radar signature is tested in the anechoic. chamber at the. theoretical and applied electrodynamics here in moscow the chamber is

completely covered in great jobs over the material the height of the sponge pyramids corresponds with the frequency of electromagnetic radiation the climate inside the train these controls and all the equipment is built on the same foundation to prevent any vibrations from affecting the regions and this is how it works. the electromagnetic wave transceivers are located on the bottom of the chamber the waves are directed towards the narrow which conversely to plane waves simulation the effects long distances have a signals the radar behind us knows condit's takes which signals are let through the rest are scattered about the room and some are reflected back to the mirror and pizza by the transceiver which gives an indication of the nose radar profile. it's impossible to make the effect if surface of a plane equals zero or it's invisible what is possible is to minimize the distance at which it is detected and that's the aim of stealth technology you know. the

chamber is so sensitive that you can even measure the radar signature of a ball bearing with a diameter of just one millimeter this is partly thanks to the giants parabolic mirror that has a position of thirty millions of a meter the star shapes reflects any distorted waves hitting the edge of the mirror it's awards the walls to avoid any erroneous reading this. the maiden flight of the first criticise the su twenty seven took place thirty years ago and the old dated versions will still be in service in thirty years time so we such attention to detail and high technology go into the stealthy part i'm sure this isn't the last we'll see of it's either or is it. with supersonic stealth fighter jets in the it may seem like anything on the ground doesn't stand a chance but this next piece of equipment is a must. as may just be even the. military engagements are being carried out to lessen. less on the battlefield and more and more on the electromagnetic

spectrum. rockets jets and drones can devastate infrastructure troops and fleets from hundreds of miles away because of their radar location systems denying the enemy while ensuring unimpeded friendly access to rates can seriously improve at defense ship losses can be hard to an aircraft losses compared to still to six fold this is the role that. the russian word for the deadly night shade plants which has been used throughout history for its poisonous and hallucinogenic properties and is a fitting name for this mobile bay dodge. this is no graded version of the system as he's capable of jamming complex radio signals which is something we weren't able to do in the past also it is so effective that one new system can replace three old ones. through its money fight should bike funds which is part of radio electronic technologies it will expire receiving the enemy signal processing it and sending

the exact same but much more powerful signal by its where it came from all in a matter of milliseconds this causes the enemy's radar screen to light so with noise leaving them on able to lock on to the targets the radio frequencies of friendly forces can be programmed in as well so they aren't affected the cross suka to also has other advantages over the previous models. are able to get works also massive if you've noticed it assumes the necessary right away and not just any position of using it. also has a self leveling system the publisher of the properties will then the in tennis starts working on this station is fully functional and ready to detect. the system is capable of hiding areas of hundreds of kilometers square and make it appear as if atomic power stations ports can treat never even existed it can also use passive radar to triangulate the position. of any bogeys without giving away

zone position because you can also has another trick of his sleeve you can make false targets appear on the radar screen which not only confuse the enemy but also priests friendly forces is such an enigmatic ally on our side these planes don't stand a chance. that's just the end of the first so don't take off see you after the break . to move. a. plane it was terrible they come up very hard to make out what the fuck you get a little long there was a cloud line that you never had sex with her right there no one's. going to want to.

listen to the fleetwood plan. move. slowly move the flames. quickly. put them up. a little. league. more news today volunteers once again fled up the families are the images the world has been seeing from the streets of canada. the giant corporations are all today claiming.

dramas that transfield ignored. stories others refused to notice. faces changed the world's lights never. told pictures of today's news. on this month from around the globe. up to. fifty. welcome bok marx may have stolen the show this time let's take a quick look back at this month's all the tech news. bytes ministers from the seven

states participating in the east projects met in france on the sixth of september which is based around the russian event it's the world's largest experimental fusion facility and has the potential to solve the world's energy problems during the meeting the ministers reaffirmed the importance all on the dedication of the project. the expo fifty eight exhibition was held for the fourth time this month the international events demonstrate their latest trains rail cars and engineering equipment to potential buyers among the highlights was a model of a next generation metro jointly designed by siemens and washing machines. more comfortable spacious quieter cheaper to run and easy to maintain and those currently in service so hopefully it will make my commute in the morning stressful bush an astrophysicist. and alex pinsky awarded the gruber cosmology prize for their contributions to inflationary theory by predicting the period before the big

bang theory is an essential components to understanding the evolution and structure of the universe it explains why the university so uniform and. significant to radio astronomy. number of different experiments followed including i mean i. explore an experiment. for which george smoot received the nobel prize. you know if this experiment proved that the universe has irregularities. in keeping with this month's aviation theme we travel to the quiet. to see a world where pot is lost up to five times longer and scientists play with planes to make our lives. on something a lot. also may already have come to china or go off on the swiss some migrating

self but that doesn't mean that the scientists have gone to hibernation. in funds the latest innovation is just about to take off here the institute of problems of chemical physics from the outside it may look like we're a group of boys with that choice but this was inside this plane that matters this is the first plane in russia to be powered soley by hydrogen fuel cells could fly for ninety minutes on a lithium polymer battery which may not seem that bad but now it's insides have been replaced they can stay in the air for almost eight hours. as well as being able to fly longer hydrogen fuel cells of other benefits over batteries or combustion engines they are quieter cooler cleaner and have a high energy conversion rate and compared to botches their lights and have a longer operating life hydrogen is an extremely clean fuel as it's only a mission is water and they can even be produced using energy from the sun so having seen what he could do i was keen to find out more. a lot of the research and

development that went into creating the fuel cells was tried out in this lab a fuel cell is like a cross between a battery and an engine they generate electricity like a battery but like an engine they require a fuel which in this case is hydrogen to the technology originate. there were fuel cells produced which were used in space the similar ones were used in submarines and are still in use to this very day so the initial technology was finalized and completed in its current form. tween the one nine hundred seventy s. and one nine hundred eighty s. if you need to get with me. a basic hydrogen fuel cell consists of a proton exchange membrane or electrolytes in the middle a catalyst on either side and i note and cathode and two graphite flow feel plates hydrogen flows on one side of the membrane and on the other the catalyst splits the hydrogen molecule into protons and electrons the protons can pass through the membrane but the electrons khans and have to pass through

a circuit which generates electricity. on the other side of the membrane the protons and electrons reacts with the allston from the air thanks to the other catalyst which generates water and heat these thin fuel cells can be stacked to produce as much power as necessary. i doubt the plane would get very far to use the graphite plates using hydrogen cars so the institute has managed to miniaturize the technology to such an extent that this block contains over one hundred fuel cells the flow fields that channel the gas saw etched into thin sheets of carbon in a slab and the finished fuel cells are tested in this machine so why did they decide to stick them in unmanned aircraft but there would be no firstly unmanned aircraft. secondly these devices are not very technically. but they require extremely accurate weight and i mentioned parameters the weight of this power source is one of its main benefits if we think of it that the institute

has three different drone models based around the same fuel cell system the design of the aircraft is tailored to the role it must perform one of them can even fly for up to thirty four hours this potato has been adapted to take three d. images of buildings and to rain the fuel cells are perfectly suited to the long flights required to take the high resolution images and do no damage the environment is can also be used to check for breaks in remote pole lines and is currently monitoring the construction of the wind. limpy facilities in sochi. unmanned aircraft is a flying machine which you can demonstrate but when if this technology works it can also be used in logic but not directly at all aircraft have no exit or a power unit which is used to heat the food at the air conditioning and a number of other flight functions are all the world's leading companies have their own hydrogen fuel cell projects. and our company is working with them on creating

these power cells of a slightly different scale. aside from aviation fuel cells offer a greener quiet and more reliable alternative to diesel backup generators as well as being useful for those living in remote areas it is of special interest to telecoms in intensive care units where reliable energy source community difference between life and death a german company is currently looking to localise production of this units in russia which can generate up to to close of energy for up to seventy two hours that he so we are using western experience in russian and developments in implementing russian developments in western products hopefully what we do here with the russian developed a membrane electronic units will return as a finished product. the only possible drawback of fuel cells is the use of compressed gas cylinders to store the hydrogen. because when you're explains that they only fill the super strong composite gas cylinder to just hottest racing of

six hundred atmospheres i no longer felt the need to run and duck for cover i'm afraid that's it for this month aviation special but whether your frequent flyer or you've quit to keep your feet firmly planted on the ground enjoy the ride. the island is so small the burmese it's the center see the center of the universe. on a tiny island the size of a football field in the middle of a lake stanza ruined monastery forty years ago to lovers decided to spend their honeymoon here. they have no idea but the island would change their lives forever but they would change the fate of the island. police never seen anything like this
