Problem $06\mathrm{.}004-$ Calculate power and velocity required $-$ DEPENDENT MULTI$-$PART PROBLEM $-$ ASSIGN ALL THE PARTS

Skip to question

Consider an airplane patterned after the Beechcraft Bonanza V$-$tailed, single$-$engine light private airplane. The characteristics of the airplane are as follows: aspect ratio $=6\mathrm{.}2,$ wing area $=181$ ft$2,$ Oswald efficiency factor $=0\mathrm{.}91,$ weight $=3000$ lb$,$ and zero$-$lift drag coefficient $=0\mathrm{.}027.$ The airplane is powered by a single piston engine of $345$ hp maximum at sea level. Assume the power of the engine is proportional to free$-$stream density. The two$-$blade propeller has an efficiency of $0\mathrm{.}83.$ Assume V $=250$ ft$/$s and $=0\mathrm{.}002377$ slug$/$ft$3$ at sea level.

Problem $06\mathrm{.}004.$c $-$ Calculate velocity and power required

Calculate the velocity, Valt, and power, PR$,$alt, required at $12,000$ ft altitude. Assume at $12,000$ ft $=1\mathrm{.}64810-3$slug$/$ft$3.$

$$

The velocity, Valt, required at $12,000$ ft altitude is ft$/$s$.$

The power, PR$,$alt, required at $12,000$ ft altitude is hp$.$
