A 500-hour test was undertaken in 1948 [1] and the Mamba was the first turboprop engine to power the Douglas DC-3, when in 1949, a Dakota testbed was converted to take two Mambas. The Mamba was also developed into the form of the Double Mamba, which was used to power the Fairey Gannet anti-submarine aircraft for the Royal Navy.
The Armstrong Siddeley Double Mamba is a turboprop engine design developed in the late 1940s of around 3,000–4,000 hp (2,200–3,000 kW). It was used mostly on the Fairey Gannet anti-submarine aircraft developed for the Fleet Air Arm of the Royal Navy .
The full scale aircraft was estimated to have a maximum speed of 1,095 km/h (680 mph), [1] but the initial converted Mamba, the SM-1, which was test-flown under a de Havilland Mosquito in 1948 and was the first turbofan to fly, [citation needed] did not generate adequate thrust. Considerable further work was required for the definitive two ...
There is little evidence to support the TR-3's existence; however, it is possible that black triangle UFO reports associated with Black Manta could be a technology demonstrator for a potential new-generation tactical reconnaissance aircraft, and/or that TR-3 refers to a Technical Refresh of an existing program.

The aircraft was to be powered by the Pratt & Whitney J58 engine, but J58 development was taking longer than scheduled, so it was initially equipped with the lower-thrust Pratt & Whitney J75 to enable flight testing to begin. The J58s were retrofitted as they became available, and became the standard engine for all subsequent aircraft in the ...
The military helicopter that collided with a regional jet near Ronald Reagan Washington National Airport, in a crash that killed all 67 people aboard both aircraft, was a UH-60 Black Hawk ...
As its predecessor, the Black Hawk, is designed for day and night military use, the Fire Hawk comes standard with low cockpit lighting, rendering it capable of flying and attacking fires after the ...
The IAC Mamba is an Australian two-seat light aircraft. It was designed and built by the Melbourne Aircraft Corporation (MAC) and first flew in 1989 as the MAC Mamba . [ 2 ] In 1990, MAC changed its name to the International Aircraft Corporation (IAC).
