You’re a pilot for the Navy. For your airplane to be able to lift itself off the ground, it must be traveling forward with a speed of 208 km/h (130 mph).

a. The force exerted by the air on the airplane causes it to accelerate down the runway. How long must the runway be for the airplane to reach its takeoff speed if it accelerates one foot per second?

c. How does a helicopter fly that allows it to land in a smaller space then a jet?

d. Why do aircraft carriers use more jets than helicopter?

e. What is a sonic boom, and what causes it?

Solution

a) The airplane will be able to take-off when it reaches 130 miles per hour at which time it will have 50,000,000 joules of kinetic energy. 50,000,000 joules means 50,000,000 newton meter. Accelerates at 1 foot per second.

You will get 200 meter as answer.

c) pilot should avoid vortex ring state , during landing a helicopter in a smaller space.

Descending gradually and should keep rate of descent low and vertical descent at last minute.

d) Aircraft carrier serves as seagoing airbase , equipped with full length flight deck and facility for carrying arming , deploying and recovery aircraft.

Four main configuration of aircraft :

CATOBAR, STOBAR ,STOVL, helicopter carrier .

e) Sonic boom is a loud sound kind of like an explosion . Its caused by shock waves created by any object that travels through the air faster than the speed of sound. Sonic booms create huge amount of sound energy . when an object moves through air , it makes pressure wave in front of and behind it.
