Behind the two-blade propeller a hydraulic pump can be seen, besides power, the RAT provides emergency hydraulic pressure. The RAT generates power from the airstream by ram pressure due to the speed of the aircraft. It may be also called an air driven generator (ADG) -

$Left abandoned outside a hangar to the elements, this huge cargo plane is slowly becoming overgrown with moss and algae, the dirt is streaking down its hull, and the crevices around the engines are being used as nesting sites by birds. \n\nThe plane is monstrous however, 4 gigantic propeller engines - 2 per wing - power what was obviously once a beast of an aircraft, the size easily allowing it to carry troops, supplies, even vehicles in its hold. \n\nNow it stands as a piece of aviation history, obviously disused and obsolete, the tech has been surpassed by more moden aircraft.$
