Estimate the landing ground roll distance at sea level for the CJ-1. No thrust reversal is used; however, spoilers are employed such that L drag coefficient by 10 percent. The fuel tanks are essentially empty, so neglect the weight of any fuel caried by the airplane. The maximum lift coefficient, with flaps fully em- ployed at touchdown, is 2.5. 0. The spoilers increase the zero-lift,
A Mitsubishi A6M Zero which has a wing area of 22.44 square meters with a lift generated of 6,000 N. If the wingspan is 12 meters, Calculate the velocity at minimum thrust required at standard sea level conditions. Assume wing is an elliptical planform and parasite drag is 0.045.
2.4 A 2650-lb car is traveling at sea level at a constant speed. Its engine is running at 4500 rev/min and is producing 175 ft-lb of torque. It has a drivetrain efficiency of 90%, a drive axle slippage of 2%, 15- inch-radius wheels, and an overall gear reduction ratio of 3 to 1. If the car's frontal area is 21.5 ft², what is its drag coefficient?
