SIFT Army Aviation Information Section Complete Study Guide 2024. A Helicopter - correct answer Is a type of rotorcraft that is able to takeoff and land vertically, hover, and fly forward, backward, and side to side (laterally). Thrust engine - correct answer an engine that produces power and delivers it to overhead and tail rotors (on most helicopters) via one or more transmissions and drive shafts. Fuselage - correct answer Main Body of the helicopter Mast - correct answer Shaft ...

army aviationthe lift and thrust must exceed the weight and drag. increasing main rotor blades' AOA while maintaining their rotational speed creates extra lift and the aircraft ascends. Decreasing the pitch results in a descent. - correct answer vertical flight the increased efficiency of the rotor disk caused by interference of the airfloe when near the ground - correct answer in ground effect also known as dual rotor; has 2 large horizontal rotor assemblies instead of one main assembl...
