Question 4 a) A helicopter pilot sets the aircraft in horizontal forward flight by activating the rotor disk tilt so that the generated thrust is tilted in the forward direction. The forward velocity of the aircraft, V and the thrust force, F acting on the centre of mass are shown in Figure 4.1. The direction of the gravitational acceleration, g is also shown. Which forces need to be accounted for when considering the equilibrium of the aircraft? Complete the sketch by adding the missing forces and provide a clear explanation of the balance of the forces in a vector form. F
