Which of these is one of the three types of drag that constitute total drag? CORRECT ANSWER Parasite. The force that resists the movement of a helicopter through the air and is produced when lift is developed is called drag. Drag must be overcome by the engine to turn the rotor. Drag always acts parallel to the relative wind. Total drag is composed of three types of drag: Profile, induced, and parasite Which of the following is common to all turbine helicopters, but is only on some piston...
