There are two very general types of aircraft propellers: Fixed pitch and variable pitch propellers. Fixed pitch propellers are simply airfoils attached to the engine which spin and due to Bernoulli's principle, cause a lower pressure at the front of the propeller than they do at the back, thereby "pulling" the aircraft forward. They are controlled simply by a throttle lever which directly affects the RPM at which the propeller spins. Variable pitch propellers expand on this concept by allowing the pilot to vary the pitch at which the propeller is angled. By varying this, multiple angles of attack can be imposed on the propeller, meaning the pilot can select a certain angle to achieve greater climb performance, and then change the angle of the blade to achieve greater fuel efficiency. This type of propeller is controlled by two systems - the throttle, which controls the manifold pressure of the engine, and the "prop" control, which changes the angle of the propeller blade.

What are the three types of propeller installation in aircraft?
just put the propeller in the aircraft
What are the two types of military aircraft?
jet and propeller
Do airplanes have one propeller?
Many small aircraft have 1 propeller.
What is the function of aircraft propeller?
To "propel" the aircraft through the air.
Main purpose of aircraft propeller?
The main purpose of an aircraft propeller is to pull the aircraft through the air. and also to convert the rotational force to thrust or lift.
How does a propeller driven aircraft fly?
The propeller pushes or pulls the aircraft forward, once sufficient forward speed is attained the wing can produce lift and the aircraft flies.
What is aircraft propeller?
A propeller is the object on the aircraft that rotates to produce thrust almost like a fan makes wind... it aims the wind behind it and pushes the aircraft forward
What is the power source in the form of a propeller on an aircraft?
Power sources for propeller driven aircraft are usually either a gas turbine or a piston cylinder engine. There are other, obscure types, usually variations of a internal combustion engine, or an electric motor like in the Helios
How does aircraft propeller work?
the motor spins the propeller like a turbine. isn't it obvious, idiot .
What is a Cherokee aircraft?
The "Cherokee" is a model of Piper Aircraft. It is a single engine, propeller driven, low wing aircraft.
Is pilot or propeller part of an airplane?
The PILOT is considered part of the CREW. The PROPELLER is a part of the actual aircraft.
What is aircraft propeller and what function does it do to the aircraft?
An aircraft propeller is what gives the aircraft power to move it forward (or backward, depending on it's pitch). This enables the aircraft to acquire lift and gain altitude. Propellers are found on some fixed-wing aircraft and autogyros. On helicopters, the blades that lift it and stabilize it are called rotors.
