What is a g-force? How do g-force affect the human body?
The GE J-79 turbojet produces a thrust of 10,000lbs at sea level. The inlet diameter is 3.19 ft.
The Anglo-French Concorde supersonic transport has an ogival delta wing with an aspect ratio of 1.7. Assuming a triangular planform shape, estimate the low-speed lift coefficient for this wing at an angle of attack of 25°.
Consider a wing with a thin, symmetric airfoil section in a Mach 2 airflow at an angle of attack of 1.5°. Calculate the lift coefficient
Using Helmbold's relation for low-aspect-ratio wings, calculate the lift coefficient of a finite wing of aspect ratio 1.5 with an NACA 2412 airfoil section. The wing is at an angle of attack of 5°.
Consider a finite wing of aspect ratio 4 with an NACA 2412 airfoil; the angle of attack is 5°. Calculate (a) the lift coefficient at low speeds (incompressible flow) using the results of Prandtl's lifting line theory, and (b) the lift coefficient for \(M_{\infty}\). Assume that the span efficie
