Can a motorcycle engine lift small homemade aircraft?

Can a motorcycle engine lift small homemade aircraft?

Yes. you need around 9 bhp to get a very light aerofoil wing carrying a human off the ground. 100 years ago a good biplane fighter had less than 100 bhp but any small high output engine would need reduction gearing to be able to maintain high revs and power while turning an airscrew.

Do helicopters have AC?

Yes. Quite a number of high end civil helicopters have air conditioning systems installed. Most often, they are fitted on medium helicopters at the request of the clients. On some heavier aircrafts however, it is standard configuration.

What does the tail of a helicopter do?

The tail rotor balances the forces generated from the main rotor and also allows the pilot to adjust the direction the nose is pointing when the chopper is hovering.

What is the purpose of the free wheeling unit in a helicopter?

Freewheeling Unit Since lift in a helicopter is provided by rotating airfoils, these airfoils must be free to rotate if the engine fails. The freewheeling unit automatically disengages the engine from the main rotor when engine revolutions per minute (rpm) is less than main rotor rpm.

What war validated the use of helicopters in battle?

The “1st Air Cav” became one of the most storied units of the Vietnam War, which became known as the “helicopter war.” Given the terrain and the enemy insurgency in that conflict, helicopters — usually the UH-1 “Huey” — gave US forces a tactical advantage.

How do you counter a helicopter torque?

The helicopter rotor system is the rotating part of a helicopter that generates lift. A rotor system may be mounted horizontally, as main rotors are, providing lift vertically; and it may be mounted vertically, such as a tail rotor, to provide lift horizontally as thrust to counteract torque effect.

How do you counter a propeller torque?

Prop torque is not countered by moving the rudder or by setting rudder trim. It is countered by moving or trimming the aileron. This correction induces adverse yaw, which is corrected by moving or trimming the rudder (right rudder).
