de Havilland CanadaDHC-1 Chipmunk is a tandem, two-seat, single-engined primary trainer aircraftwhich was the standard primary trainer for the Royal Canadian Air Force, Royal Air Forceand several other air forces through much of the post-Second World War years. The de Havilland Chipmunk was the first true postwar aviation project of de Havilland Canada.
Today, over 500 DHC-1 Chipmunk (affectionately known as "Chippie") airframes remain airworthy with more being rebuilt every year.
Design and development
The Chipmunk was designed to succeed the
de Havilland Tiger Moth biplanetrainer that was widely used during the Second World War. Wsiewołod Jakimiuk, a Polish prewar engineer, created the first indigenous design of the aircraft at de Havilland Aircraft of Canada Ltd. It is an all-metal, low wing, tandem two-place, single engine aircraft with a conventional tail wheel landing gear and fabric-covered control surfaces. The wing is also fabric-covered aft of the spar. A clear perspex canopy covers the pilot/student (front) and instructor/passenger (rear) positions. "CF-DIO-X", the Chipmunk prototype, flew for the first time at Downsview, Torontoon 22 May 1946 with Pat Fillingham at the controls [Bain 1992, p. 141.] . The production version of the airplane was powered by a 145 hp in-line de Havilland Gipsy Major8 engine while the prototype was powered by a 108 kW (145 hp) de Havilland Gipsy Major 1C.
Two Chipmunk aircraft were evaluated by the
Aeroplane and Armament Experimental Establishmentat Boscombe Down. As a result, the fully-aerobatic Chipmunk was ordered as an "ab initio" trainer for the Royal Air Force( Prince Philiptook his first flying lesson in one in 1952). The Royal Canadian Air Forcealso adopted the Chipmunk as their primary trainer.
British-built and early Canadian-built Chipmunks are notably different from the later Canadian-built RCAF/Lebanese versions. The later Canadian-built airplanes have a
bubble canopy, while early Canadian, and all Portuguese and British examples have the multi-panelled sliding canopy, the rearmost panels of which are "bubbled" out for better instructor visibility.
From the 1950s onward, the Chipmunk also became a popular civilian aircraft, being used for training,
aerobaticsand crop spraying. Most civilian aircraft are ex-military.
One of the most famousWho|date=September 2008 civilian Chipmunks was the US-basedClarifyme|date=September 2008 "Super Chipmunk," a highly-modified air show performer. Along with an uprated engine, the aircraft underwent an extensive makeover including clipping its wings, adding retractable landing gear, conversion to a single-seat layout, adding an autopilot and being fitted with a red, white and blue wingtip and tail smoke system. The control stick received a three-inch extension for greater control during extreme aerobatic maneuvers. For over 25 years the Super Chipmunk in its distinctive bright color scheme of blue stars and sunburst effect was the late, legendary aerobatic pilot Art Scholl’s personal ride — used to perform a unique and breathtaking aerial routine that culminated in his signature move, the "Inverted Ribbon Pickup."
Three Super Chipmunk conversions were made, Scholl's "N13A" and "N13Y" and Harold Krier’s "N6311V". Another more recent "Super Chipmunk" was converted by air show performer, Jim "Fang" Maroney who similarly modified an ex-RCAF example by strengthening the airframe, replacing the original 145 hp engine with a 260 hp version incorporating an inverted fuel and oil system, clipping three feet off the wings and adding 30% more rudder and 10% more elevator. A spatted landing gear was retained. Other similarly converted "Super Chipmunks" are currently being flown by air show performers Greg Aldridge and Steve and Suzanne Oliver. "N13Y" is now on display at the National Air and Space Museum, Smithsonian Institution, Udvar-Hazy Center at Washington-Dulles International Airport.
The RAF received 735 Chipmunks, designated Chipmunk T.10, manufactured in the UK. They initially served with Reserve Flying Squadrons (RFS) of the
RAF Volunteer Reserve(VR) as well as the University Air Squadrons. A few Chipmunks were pressed into service in Cypruson internal security flights during the conflict in 1958. Some were from 1956 to 1990 used for covert reconnaissance by BRIXMISoperating out of RAF Gatow, Berlin.Fact|date=January 2008They were still in service for ATC Air Experience Flights until 1996 (the final AEF to use the Chipmunk was No. 10 Air Experience Flight, RAF Woodvale) when they were replaced by the Bulldog (itself replaced by the Grob Tutorin 1999-2001). Chipmunk T.10s were also used by the Army Air Corps and Fleet Air Armfor primary training. The last Chipmunks in military service are operated by the British historic flights - the RAF Battle of Britain Memorial Flight(including one of the BRIXMISaircraft), the Royal Navy and Army historic flights, to keep their pilots current on tailwheel aircraft for flying displays in the UK.
The RCAF accepted its first DHC-1 Chipmunks in 1948 and did not retire the last one until 1972, three years after unification in 1968. The Chipmunk's long service was due, in part, to its fully aerobatic capabilities and superb flying characteristics, which made it a delight to fly. It is also a mechanically sound aircraft and, consequently, many ex-RCAF Chipmunks are still operational around the world.
Downsview built 217 Chipmunks, the last in 1956. A total of 1,000 were built in Britain initially at
Hatfield Aerodromeand then later at Hawarden Aerodrome. A further 66 Chipmunks were licence-manufactured by OGMA (Oficinas Gerais de Material Aeronáutico, at Alverca) from 1955 to 1961 in Portugalfor the Portuguese Air Force.
