APACHE ENGINEAH-64 APACHE Turbo shaft jet engines are used.
Principle-"suck, squeeze, burn and blow.
Power is transferred from the engine using a main gearbox
WORKING
AH-64 APACHE
Slight angle of attack given to shaft and spins the shaft. Power is transmitted from engine to rotor by gearbox Tail rotor produces thrust. Sideways thrust resists engines desire to spin the body.
