(a) plane has a wing using a NACA 2410 aerofoil. It is an altitude of 8000m and has an angle of attack of 5deg. How far could it glide in km. (4s.f, tolerance +/- 0.1km)?

(b) same plane (with NACA 2410 aerofoil) still at an altitude of 8000m is now flown with an angle of attack of 2degree. How far could it now glide in km? (4s.f)

Expert Solution

(a) glide angle(a) = angle of attack = 5 deg

Height (h) = 8000 m

Length = L

tan(a) = h/L

tan(5) = 8000/L

L = 8000/0.087

= 91440 m

= 91.44 km

(b) similarly

tan(2) = 8000/L

L = 8000/0.034

= 229090m

= 229.1 km

A rectangular wing with a NACA 65-210 airfoil section and a chord of 6 in is mounted in the Auburn University 2 ft × 2 ft wind tunnel, completely spanning the test-section. The tunnel is operating with test section velocity, pressure, temperature, and velocity of 1 atm, 520°R, and 75 ft/s, respectively. (a) Calculate the lift, drag, and moment about the quarter-chord when the angle of attack is 5°. (b) What angle of attack would be required to generate a...

A wing component on an aircraft is fabricated from an aluminum alloy that has a plane strain fracture toughness of 30 MPa (m) 1/2 . It has been determined that fracture results at a stress of 120 MPa when the maximum internal crack length is 8.4 mm. For this same component and alloy, Compute the stress level at which fracture will occur for a critical internal crack length of 5.6 mm?
