Question

The 30 Mg aircraft is climbing at the angle (theta)=15 with a thrust T of 180 kN.

At the instant shown, its speed is 300 km/h and is increasing at the rate of

1.96 m/s^2; theta is decreasing as the aircraft begins to level off. If the radius of

curvature of the path at this instant is 20 km, compute the lift L and drag D

experienced by the aircraft as well as the total normal force imposed on the

90-kg pilot by his seat. ( Lift and Drag are the aerodynamic forces normal to

and opposite the ight direction, respectively. You may assume the seat pan is

aligned with the aircraft's direction of travel and that the seat back is

perpendicular to it.)

Ans. D = 45.0 kN, L = 274 kN
