p.w. fourteen hundred g. or the specially designed new p.t. for the project of russia's. is to provide the advantage of cheap engines without compromising performance parameters and available resources most importantly in terms of the lifecycle cost as compared to competitors of. the it's important to point the way regarding this engine as the plentiful on the basis of which engines will be designed for the home run of the plane to p.t. fourteen is projected to meet and exceed international standards on fuel consumption emissions and noise pollution new engines are restored but they aren't the only innovative rethink for the year could jet. are leading aerodynamics is that your soggy made a crucial contribution to this project their experts produced a new concept for wing design. it has an altogether new profile for supercritical airfoils all of their work helps greatly improve the plane's aerodynamics in addition to this super critical design high wing aspect ratio on the wide reaching the airplane is a further aerodynamic advantage but it's largely what the wings are ma
