Fixed wing- air is moved past the wings to create lift.

Helicopter- the wings (rotor blades) are moved through the air to create lift.

What is an aircraft without fixed wings?

A helicopter is an aircraft without fixed wings. Helicopters can also be known as rotorcraft.


What is the difference between a helicopter and an airplane?

Helicopters are "rotary wing" aircraft- their wings are the rotor blades. Instead of deriving lift from moving air over the fixed wings of an airplane, a helicopter derives lift by moving the wings through the air.


What is the difference between the way airplane and a helicopter fly?

The basic difference can be boiled down to this: The similarities between the two is that they both fly from air moving over the airfoils. On a plane this is also called the wing, on a helicopter it's called the rotor. Since the airplane is a 'fixed wing' aircraft, the plane must be moving forward in over to fly. On a helicopter the spinning rotor generates lift all the time.


Why was the helicopter intoduced?

To get access to places fixed wing aircraft cannot go.


Why fixed wing aircraft need less power full engine to fly then a helicopter?

Helicopter 'lift' is provided by the rotor blades creating lift. A fixed wing aircraft creates lift by moving the aircraft forward to create a pressure differential between the upper and lower surfaces of the wing. Power required from the engine to a propeller to move the aircraft forward (on wheels) to gain sufficient speed is much less than lifting the 'dead' weight of a helicopter.


Why was the helicopter so important?

Because they can do so many things fixed wing aircraft can not do


How is it to fly a helicopter?

Much more complicated than a fixed wing aircraft. -Military helicopter pilots in most services MUST qualify as fixed wing pilots before graduating to helicopters.


What is the science behind a helicopter?

In avionics, a helicopter is known as a Rotary Wing Aircraft. (As distinct from a fixed wing aircraft. ) This indicates the operating principle is based on the ordinary wing profiles used to generate lift.


Why does the rotors spin on an helicopter?

The rotor blades on a helicopter work the same way as wings on a fixed wing aircraft. The air passing faster over the top of the airfoil generates lift. Helicopter rotors spin so that the lift is generated without having to have forward airspeed like a fixed wing aircraft.


Is a helicopter more reliable than a plane?

Due to the complexity of a helicopter, it requires MORE maintenance than a fixed wing aircraft of a similar size. Having flown both, I would consider a helicopter less reliable,


What is the difference between a airplane and an aircraft?

An aircraft is any flying machine including blimps, helicopters, hot air balloons, etc. An airplane is a fixed wing aircraft like an airliner or personal General Aviation plane.
