Aerodynamics

Use this for “Air at 1.225 kg/m³ and 50 m/s speeds up to 60 m/s over the top of a wing. Find Cₚ and p − p∞.”

Use this for “Air at 1.225 kg/m³ and 40 m/s; the circulation round a 1.5 m chord is 20 m²/s. Find L′ and cₗ.”

Use this for “What does NACA 2412 mean? Give the camber and thickness of a 1.5 m chord.”

Use this for “A wing has CD0 = 0.025, AR = 8 and e = 0.8. Find CD at CL = 0.5 and the best L/D.”

Use this for “Air at 1.225 kg/m³ with μ = 1.789 × 10⁻⁵ Pa·s flows at 60 m/s past a 1.5 m chord. Find Re.”

Use this for “Which kind of drag do a golf ball’s dimples cut, and which do long glider wings cut?”

Use this for “An airfoil with a₀ = 2π per radian makes a wing of aspect ratio 8 and e = 0.9. Find the wing’s lift slope a.”

Use this for “A wing spans 12 m with a 1.8 m root chord and a 0.9 m tip chord. Find λ, S and AR.”

Use this for “At low speed, a point on a wing has a pressure coefficient Cₚ = −0.4. What is Cₚ at that point when the wing flies at M = 0.6?”

Use this for “An airliner cruises at M 0.85. Is its flow subsonic, transonic, supersonic or hypersonic?”
