= = = 2 = An aircraft with the attitude of Y = 40°, 8 = 5', 0 = 0° flies at a constant airspeed of va [230, 15, 3]* m/s. The mass of the aircraft is 5 x 104 kg. The wind speed vector in the body frame is V = [2.5, 0, – 0.5]" m/s. 2.1. What is the angle of attack, and what is the sideslip angle? (2 marks) 2.2. What is the airspeed vector in the wind frame? What is the airspeed vector in the vehicle frame? What is the ground speed vector in the body frame? (4 mark) 2.3. Suppose the aircraft starts to roll at the rate of 0.35 rad/s. What is the angular velocity in the body frame? What is the required force in the body frame for such an angular velocity? (4 marks)
