MD 902 History

HELIHoMe history 📜 😉 : The MD Helicopters MD Explorer is a light twin utility helicopter. Designed in the early 1990s by McDonnell Douglas Helicopter Systems, it is currently produced by MD Helicopters. There have been two models, the original MD 900, and its successor, the MD 902 📝 In January 1989, McDonnell Douglas Helicopters officially launched the development of the Explorer, initially referred to as MDX. The Explorer was the first McDonnell Douglas helicopter to incorporate the NOTAR system from its initial design. McDonnell Douglas partnered with Hawker de Havilland of Australia to manufacture the airframes. 10 prototypes were built with seven being used for ground tests. McDonnell Douglas Helicopters became a launch customer for Pratt & Whitney Canada's PW200 series of engines, with an exclusive agreement to power the first 128 Explorers with two PW206As. Meanwhile, plans to offer the Turbomeca Arrius as an option were dropped. The first flight of the Explorer took place on 18 December 1992, with ship #2 (N900MD). FAAcertification for the Explorer was granted on 2 December 1994, with JAAcertification following shortly after. 📰 In September 1997, a range of improvements were introduced, including PW206E turboshafts with higher single engine inoperative ratings, revised engine air inlets, improved NOTAR inlet design and a more powerful stabiliser control system. Benefits include improved range and endurance and an increased maximum takeoff weight. This enhanced Explorer was unofficially designated the MD 902 📖 MD 901 Explorer Civil utility transport model, powered by two Turbomeca Arrius turboshaft engines and tri-angel landing gear. McDonnel Douglas Helicopters announced that this type was available from serial number 127 and upwards. By sale of civil helicopter variants to MD Helicopters the type was not further developed. None ordered. MD 902 Marketing name for an enhanced version with Category A approval and powered by two Pratt & Whitney Canada PW206E or PW207E. Enhanced version has additional engine isolation features and changes to the Integrated Instrument Display System. Older helicopters (except for the first seven built) can be modified to the enhanced version.
