Bookmark or Share- helicopter - How is rotor airfoil analysis different than fixed wing ...That said, while most of the labels on that diagram are familiar from fixed-wing flight, there are a few that should be different, namely: the induced velocity, inflow angle, and tangential velocity. As you stated, the horizontal speed of the blade is going to change based on where you are on the blade, radially speaking--which is absolutely ...
- How does the efficiency of a fixed wing compare to a rotary wing?Fixed wing aircraft are generally much more efficient than rotary aircraft. This is because of the difference in how they generate lift. For fixed wing aircraft, they use an engine to keep the plane moving forward. The air flow over the wings generates lift. The engine must only overcome the drag of the airplane (in level flight).
- What is a "fixed wing" aircraft? - Aviation Stack ExchangeFixed wing is a kind of heavier than air aircraft which uses fixed i.e. non-moving wings and other lifting services attached to the air frame and forward motion to generate lift. Examples include airplanes, gliders, powered lift aircraft, ultralights, powered parachute and weight shift controlled aircraft.
- aerodynamics - Why are rotary wing aircraft less efficient than fixed ...Why are rotary wing aircraft less efficient than their fixed-wing counterparts? It seems to me that the most important thing for efficiency is lift-to-drag ratio, so what makes this ratio much worse in rotary wing? Presumably it can use the same airfoil shape as fixed wing aircraft, so I could imagine a similar lift to drag ratio.
- aviation history - What is the slowest fixed-wing airplane? - Aviation ...The document covers other human-powered aircraft mentioned in other answers, including the Gossamer Condor and Albatross, so that suggests that the MIT Chrysalis was, in fact, the slowest fixed-wing manned aircraft to fly successfully.
