Do planes need torque?
5 Answers. A single engine plane can suffer from control problems due to torque. As others have pointed out, torque effects have to be countered using the normal aerodynamic controls available to the pilot. Some aircraft had extra-large ailerons because of this issue.
Are airplanes more efficient than helicopters?
The answer is – neither ! An aeroplane is more efficient over long distances, and a helicopter drastically more efficient point to point over short-medium distances. However, they are both thrashed on efficiency question by a type that stands between them – The Autogyro !
Do jet engines have torque?
Yes, a jet engine has a torque reaction, but it’s much reduced compared to swinging a big diameter propellor. One aircraft that it COULD have been a problem on was the Harrier jump jet, because it could take off vertically so it had no airspeed to provide aerodynamic methods of countering the torque.
How much torque do you need for a helicopter?
A helicopter with 9,500 horsepower might require 1,200 horsepower to drive the tail rotor, while a 200 horsepower aircraft might require only 10 horsepower for torque correction. Heading Control In addition to counteracting torque, the tail rotor and its control linkage also permit control of the helicopter heading during flight.
What’s the difference between a helicopter and an airplane?
Normally, larger helicopters use a higher percent of engine power to counteract torque than do smaller aircraft. A helicopter with 9,500 horsepower might require 1,200 horsepower to drive the tail rotor, while a 200 horsepower aircraft might require only 10 horsepower for torque correction.
What causes the torque of a helicopter rotor?
Torque results from the rotor being driven by the engine power output. Any change in engine power output brings about a corresponding change in torque effect. Furthermore, power varies with the flight maneuver and results in a variable torque effect that must be continually corrected. Antitorque Rotor
Why is track and balance important in a helicopter?
Reducing these vibration levels in the airframe to a minimum is absolutely essential in order to ensure the safety and longevity of the helicopter. Rotor track and balance is the process of smoothing vibrations in the airframe, which are caused by the main rotor.
