Question 2: Consider the 5000kg aircraft below being in a 1000m radius looping maneuver (Fig.2).
There are 4 forces acting on the aircraft (Weight, Thrust, Lift, Drag). Assuming that they are all
approximately perpendicular to eachother at points A,B,C, calculate the following:
A. Calculate the Lift Forces at points A, B, C if the aircraft was at a constant speed of 350km/h
throughout the maneuver.
B. Calculate the Lift Forces at points A, B, C if the aircraft starts the maneuver at point A at a
speed of 400km/h, but reduces its speed with constant acceleration so that the pilot feels
weightless at point C.
C. A human can withstand
earth's gravity was more than 9 times what it is now, we would not survive. What is the
maximum of 9 times the gravitational acceleration, i.e. if the
maximum speed the pilot can enter this maneuver?
