A ram air turbine (RAT) is a small wind turbine that is connected to a hydraulic pump, or electrical generator, installed in an aircraft and used as a power source. The RAT generates power from the airstream by ram pressure due to the speed of the aircraft. It may be called an air driven generator (ADG) on some aircraft. [1]
A government contract flight is a type of charter airline operation contracted with a government agency.. In the United States, the massive mobility requirements during World War II proved that military transport could not meet all the logistical needs that might arise.
A backup generator for a large apartment building A backup power fuel cell for telecom applications A portable emergency power generator in a shipping container. An emergency power system is an independent source of electrical power that supports important electrical systems on loss of normal power supply.
The flight engineer could have mistakenly set the aircraft's essential power switch to the APU position, rather than the standby (backup) position; the switch has to pass through a gate when turning from the APU position to the standby position, and the flight engineer, turning the switch until he encountered resistance, may have assumed that ...
The military has a "robust air defense system in place to defend against the potential of hijacked airlines," but the same can't be said for drones, said David Deptula, the dean of the Mitchell ...
There can be occasions when the roles of the pilots during an emergency are reversed, i.e. the copilot becomes the PNF and the captain becomes the PF; one such example was on the A300 B-Series aircraft when there was a complete loss of generator-supplied electrical power, whereupon the standby instruments that were powered were on the captain's ...
The compressed air can be supplied from an on-board auxiliary power unit (APU), a portable gas generator used by ground crew or by cross feeding bleed air from a running engine in the case of multi-engined aircraft. [19] The Turbomeca Palouste gas generator was used to start the Spey engines of the Blackburn Buccaneer.
An airborne engine drives the generator, supplied by a 100-gallon diesel fuel tank. Beginning in the late 1990s, the aerostat sites were equipped with Lockheed Martin 420K aerostats. This version carries the Lockheed Martin L-88, a surveillance radar with a range of 370 km (200 nm), as its primary payload.
