Challenge Problems
Push your limits with challenges.
Question 1
An aircraft weighs 150,000 Newtons and requires a lift coefficient of 1.2 for its design. If its wing area is 150 m², calculate the minimum airspeed required to achieve lift at sea level (ρ = 1.225 kg/m³).
💡 Hint: Keep in mind that the formula directly relates lift to velocity squared.
Question 2
Design a new aircraft wing assuming it must produce 500,000 Newtons of lift. If you decide on an airspeed of 70 m/s and a lift coefficient of 1.5, what must the wing area be?
💡 Hint: Work through the formula step by step to isolate A.
