de Havilland Dash 8-100 Aircraft - photo wallpapers; Megawallpapers.org : The de Havilland Canada DHC-8, popularly known as the Dash 8, is a series of twin-turboprop airliners designed by de Havilland Canada in the early 1980s. They are now produced by Bombardier Aerospace which purchased DHC from Boeing in 1992. Since 1996, the aircraft have been known as the Q Series, for "quiet" due to installation of the Active Noise and Vibration Suppression (ANVS) system designed to reduce cabin noise and vibration levels to nearly those of jet airliners. In the 1970s, de Havilland Canada had invested heavily in their Dash 7 project, creating what was essentially a larger four-engine version of their de Havilland Twin Otter concentrating on excellent STOL [br]and short-field performance, their traditional area of expertise. [br]However, only a handful of air carriers employed the Dash 7, as most regional airlines were interested primarily in operational costs, as opposed to short-field performance. In 1980, [br]de Havilland responded by dropping the short-field performance [br]requirement and adapting the basic Dash 7 layout to be propelled by [br]only two engines that produced more power. Their traditional engine [br]supplier, Pratt & Whitney Canada, developed the new PW100 series engines for the role, more than doubling the power from their PT6. [br]Originally designated the PT7A-2R engine, it later became the PW120. [br]When the Dash 8 rolled out on 19 April 1983, more the 3800 hours of [br]testing had been accumulated over two years on five PW100 series test [br]engines. Certification of the PW120 followed in late 1983. [Dash 8 is Born, I. Kinsey, Canadian Aviation magazine, June 1983] Distinguishing features of the Dash 8 design are the large T-tail intended to keep the tail free of propwash during takeoff, a very high aspect ratio [br]wing, the elongated engine nacelles also holding the rearward-folding [br]landing gear and the pointed nose profile. First flight was on 20 June 1983, while the airliner entered service in 1984 with NorOntair. Piedmont Airlines, formerly known as Henson Airlines, was the US launch customer for the Dash 8 in 1984. The Dash 8 design had better cruise performance than the earlier [br]Dash 7, was less expensive to operate, and more notably, much less [br]expensive to maintain. The Dash 8 had the lowest cost per passenger [br]mile of any feederliner of the era. The main disadvantage compared to [br]the earlier Dash 7 was somewhat higher noise levels, but only in [br]comparison, as the Dash 7 was notable in the industry for extremely low [br]noise due to its four very large and slow-turning propellers. The Dash [br]8 also could not match the superb STOL performance of its earlier DHC [br]forebears.[br]Country of origin: Canada [br]_________________________________________________________________________________________________ [br]Engines: two 2000hp Pratt & Whitney Canada PE120A turboprops [br]_________________________________________________________________________________________________ [br]Wingspan: 25.9 m (85ft) [br]_________________________________________________________________________________________________ [br]Lenght: 22.5 m (73ft) [br]_________________________________________________________________________________________________ [br]Height: 7.5 m (24ft 6in) [br]_________________________________________________________________________________________________ [br]Weight loaded: 15,650 kg (34,500lb) [br]_________________________________________________________________________________________________ [br]Cruising speed: 500 km/h (310mph) [br]_________________________________________________________________________________________________ [br]Service celling: 7620 m (15,000ft) [br]_________________________________________________________________________________________________ [br]Range: 2010 km (1250 miles) [br]_________________________________________________________________________________________________ [br]Passengers + crew: 36 + 2 [br]_________________________________________________________________________________________________
