Mechanical Engineering

Compute the landing ground roll for the CJ-1, assuming thefollowing landing configuration: • CLmax = 2.4 • Using 100% flapdeflection and spoilers at touch-down: • Lift coefficient = 0.4 •Drag coefficient =0.20 • Runway braking friction coefficient =0.30

CJ-1: Wingspan = 53.3ft, wing are = 138ft^2, Normal gross weight= 19815lb, Fuel capacity: 119 gal of kerosen, power plant: twoturbofan engines of 3650lb thrust each at sea level, specific fuelconsumption = 0.6lb of fuel/(lb Thrust)(h), parasite dragcoefficeint CD,0 = 0.02, Oswald efficiency factor e = 0.81
