Assembly & Rigging - Worksheet 3 Questions and Answers Graded A+

Assembly & Rigging - Worksheet 3 Questions and Answers Graded A+ What is the purpose of trim tabs in helicopter flight controls? To fine-tune control surfaces for stable flight How does excessive friction in control linkages affect handling? It makes control inputs sluggish and less precise Why must rotor blade pitch angles be set accurately? To ensure proper lift and balanced flight characteristics How does blade coning affect helicopter performance? It changes lift distribution and affects rotor efficiency Why is careful alignment of control cables necessary? To prevent excessive wear and ensure smooth operation 2 How does a freewheeling unit help in engine failure? It disconnects the engine from the main rotor to enable autorotation What happens if a control linkage is too tight? It can restrict movement and cause difficulty in control inputs Why are periodic flight control checks required? To detect wear, misalignment, or any irregularities before they cause issues What effect does tail rotor drive failure have on flight? The helicopter loses yaw control and may enter an uncontrollable spin Why is torque compensation necessary in helicopters? To balance the rotational force of the main rotor and maintain stability How does incorrect collective pitch adjustment affect lift? It can result in insufficient lift or excessive power demands 3 What is the main function of the cyclic stick in a helicopter? To control the direction of flight by tilting the rotor disk What is the primary purpose of helicopter rigging? To ensure proper alignment and function of flight control systems Why is tracking the main rotor blades important? To reduce vibrations and improve flight stability What component connects the cyclic control to the rotor system? The swashplate How does the tail rotor help control a helicopter?
