For take-off the CSU would automatically set the blade angle of a constant speed propeller at an angle which producesQuestion 8Select one:a.Equal pressure on each side of the bladeb.High drag forces on the propeller to increase power available in the climbc.A large angle of attackd.A small angle of attack
Solution
The correct answer is d. A small angle of attack.
During take-off, the Constant Speed Unit (CSU) would automatically set the blade angle of a constant speed propeller at a small angle of attack. This is because a smaller angle of attack reduces drag and allows the aircraft to accelerate more quickly. It also helps to prevent the propeller from stalling, which could cause a loss of thrust. Once the aircraft is in flight and the engine is operating at a constant speed, the CSU can adjust the blade angle to optimize efficiency.
