Question 1
An aircraft with a gross weight of 60,000 N has a maximum lift-to-drag ratio (L/D)_max of 15. What is the minimum thrust required for unaccelerated level flight at this weight?
Correct Answer:
4,000 N
Question 2
An aircraft wing has a planform area S = 30 m² and produces a maximum lift coefficient C_L,max = 1.5. Assuming standard air density ρ = 1.225 kg/m³ and an aircraft mass of 4,500 kg (weight W = 44,145 N), what is the stall speed V_s in level flight?
Correct Answer:
40.0 m/s
Question 3
In a coordinated level turn at a bank angle φ = 60°, what is the load factor n acting on the aircraft structure?
Correct Answer:
2.00 g
Question 4
Which aerodynamic phenomenon occurs when an aircraft flies at supersonic speeds, causing an abrupt pressure, temperature, and density increase across a thin boundary line?
Correct Answer:
Normal shock wave
Question 5
An aircraft has a wing area S = 100 m² and a total mass m = 50,000 kg. What is the wing loading (W/S) in N/m² (using g = 9.81 m/s²)?
Correct Answer:
4,905 N/m²
