- Use FoilSim to investigate how an aircraft wing produces lift and drag by changing the values of
different factors that affect lift and drag.
A group of researchers from UMP conducted a project collaboration with an aircraft
company to develop a small aircraft. The aircraft is designed to carry up to 2800 kg of total mass. The wing area of the aircraft is 30 m2. During takeoff, the lift coefficient of the aircraft
is 0.45. Meanwhile during cruising, the drag coefficient of the aircraft is 0.035.
iii. Evaluate the required power to maintain at cruising speed of 300 km/h.
