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.

A 2 m diameter cylinder rotates at 1800 rpm in an air stream (p=1226 kg/m³) of 25 m/sec. Estimate the theoretical lift per unit length of the cylinder (in Newtons) Ajo

A flat plate of 10ft span and 6 ft chord is placed in an airstream of 100mph under SSLC. If the transition Reynold's number is 10^6, calculate the Total Skin Friction Drag in lbs.

A three-blade propeller of a diameter of 1.5 m has a rotational speed is 60 Hz, the activity factor AF is 200 and its static torque coefficient is 0.05. The propeller's integrated lift coefficient is 0.3.

A ship is 125 m long and has a wetted area of 3500 m2.Its propellers can deliver a maximum power of 1.1 MWto seawater at 20°C. If all drag is due to friction, estimatethe maximum ship speed, in kn.

Please don't provide handwritten solution ....

Answer is: V = 14.17 ft/s

ing 16. Consider a finite wing with aspect ratio A-8 and elliptical planform. The aerofoil section is thin and symmetric. Calculate the lift and induced drag coefficients when angle of attack is five degrees.

Ign, McGraw-Hill, this chapter) and by New York, 1999, for more information. EXAMPLE 6.18 Estimate the landing ground roll distance at sea level for the CJ-1. No thrust reversal = 0. The spoilers increase the zero-lift, used; however, spoilers are employed such that L drag coefficient by 10 percent. The fuel tanks are essentially empty, so neglect the wejehr of any fuel carried by the airplane. The maximum lift coefficient, with flaps fully em ployed at touchdown, is 2.5.
