The A-1 Skyraider used as an ground attack bomber in Viet Nam had a 18-foot diameter propeller. Not sure if this was the largest. This aircraft was designed in WW2 but was too late to see much action.
Sources I have seen show the A-1 was powered by a Curtis Wright 3350 engine producing 2800 horsepower and turning a 13.5 foot (4.11 meters) propeller.
The B-36 bomber was developed as an intercontinental bomber able to take off from the US and bomb Germany. It was planned in the dark days of WWII when it looked like England would fall to the Nazis and there would be no European airfields available to support shorter range bombers. The B-36 had had 6 Pratt and Whitney R-4360 engines producing 3,500 horsepower in pusher mounts. Those engines drove 19 foot propellers (9 foot blades fixed to a 1 foot hub)
just put the propeller in the aircraft
The largest single engine propeller driven aircraft is the Grumman AF-2S Guardian, a sub chaser of the Korean War era. It grossed at 25,500 lbs and was powered by a Pratt & Whitney R2800 engine of 2400 horsepower. It also had the largest Wing span for a single engine reciprocating aircraft at 60' 8".
Many small aircraft have 1 propeller.
To "propel" the aircraft through the air.
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.
The propeller pushes or pulls the aircraft forward, once sufficient forward speed is attained the wing can produce lift and the aircraft flies.
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
the motor spins the propeller like a turbine. isn't it obvious, idiot .
jet and propeller
The "Cherokee" is a model of Piper Aircraft. It is a single engine, propeller driven, low wing aircraft.
The PILOT is considered part of the CREW. The PROPELLER is a part of the actual 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.
