A fixed-wing aircraft is one who's wings are fixed.
I suppose you want a more in-depth explanation
, the devices that produce lift
are called "wing
s." They are constructed so that as they pass through the air, they creat lift. More detail can be found in the wing
node. They pass through the air by being pushed there on an aircraft, by the aircraft's engine - but what pulls the aircraft forward, exactly?
Why, the propellor of course. The propeller is also a wing. It passes through the air by the spinning motion of the engine
, and creates lift - also, because it power
s the aircraft, it is known as thrust
The Propeller is not a fixed-wing. It is not fixed. It spins.
The wing on the aircraft is a fixed-wing. It is attached to the aircraft and does not move.
Any aircraft where the main lift-producing device (wings) are attached and do not move, are referred to as fixed-wing aircraft.
Aircraft where the main lift-producing device (wings) are NOT attached and DO move, they are referred to as ROTARY-wing aircraft
. This would include Helicopter
Note that aircraft which have slightly moving wings (some high-speed fighters and bombers for example) are called swept-wing aircraft
, and are considered fixed-wing.
