Welcome back to the our channel for a discussion about the future of military helicopters as well as some of the most advanced aircraft currently serving. The engineers will come up with new designs but the limiting factor in all this is horsepower. And jet turbine engines by design and size factors are limited to power output. You can only get so much horsepower output by given size. Their going to have to be radical new jet engine design to get more power output given the design constraints with helicopters. Basically you only have so much space and space is limited by design. I am hoping that the Defiant X wins but if it cannot carry the necessary load then having a few V-280's around would work too, The Defiant X is superior for troop transport as it will require a much smaller LZ than the Valor, also my mom has heard the Valor fly and it is the loudest aircraft she has ever heard in person, but the Defiant is much quieter. The Black Hawk cannot reach speeds of over 200 mph. A clean UH-60 on a perfect day can reach about 160 knots, or 185 mph. I really like the propulsion of the Sikorsky designs. Co-axial rotors plus a pusher-prop seems the way to go. Compared to a tilt-rotor, it should be more maneuverable and have a smaller footprint. What I don't like about the attack version is the side-by-side seating. That makes for an unnecessarily fat fuselage, increasing the likelihood of getting hit by enemy fire. Also, with side-by-side seating, neither pilot is lined up with the center of the fuselage. Attack helicopter pilots are accustomed to tandem seating and they like it. I don't understand why Sikorsky is not using that seating arrangement.
