2022年1月20日 · Fixed 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.

2014年6月3日 · 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).

2016年6月13日 · Fixed wing aircraft are more efficient than forward flying helicopters because: The rotor flow in forward flight causes fearsomely complex aerodynamic interactions in flow with the fuselage and other components, which causes a particular type of drag that a fixed wing simply does not have.

The function of the tail section of a conventional fixed wing aircraft is to provide stability. It also holds two important control surfaces; the rudder and the elevator. The vertical tailplane, also called vertical stabilizer helps the aircraft's nose facing into the direction of the relative air flow.

The distinction between STOVL and V/STOL is largely a matter of naming. As it stands, no one has operationally deployed a fixed-wing aircraft that can land vertically, but cannot take off vertically. All modern aircraft referred to as STOVL or V/STOL are, in technical terms, VTOL (as well as STOL) capable aircraft.

2015年10月5日 · Note that some aircraft will fly a nose-down attitude by design. The Boeing B-52 has powerful flaps which are designed to allow it to lift off without rotating, and when the aircraft accelerates during the initial climb after take-off or flies its approach, the fuselage will have a nose-down attitude. See the picture below of the B-2, the B-1B ...

Helicopters have a lot of extra drag that fixed wing planes don't have: Complex interference drag from the rotor/fuselage etc. interaction. In forward flight: higher induced drag, due to the disk shaped lifting surface having a much lower aspect ratio than fixed wings.

2017年5月18日 · $\begingroup$ GdD is correct. Lots of factors go into takeoff performance; engine type being just one. That said, if all things are equal and somehow you had the engines on the exact same aircraft, I would guess that you'd also have to reduce weight on the turbofan to keep it equivalent with the turboprop, thus reducing engine size and thrust capability.

2018年1月29日 · Has there ever been a fixed-wing aircraft whose propeller is in a scissor configuration? Like the Apache's tail-rotor seen here: What are the benefits of a non-orthogonal (scissor) tail-rotor? This configuration improves the thrust and reduces the noise. If not, what are the drawbacks for such configuration when used for forward thrust?

2017年1月23日 · Has a fixed-wing aircraft ever been conceived, prototyped or built that features multiple turbines powering a single propeller? The concept of a twin-engine aircraft with a single propeller is intriguing to me. Picturing something like a Pilatus PC-12 with two engines under the hood and a single prop might have some advantages.
