The Aircorp B2-N Bushmaster[a] is a prototype Australian light aircraft designed for aerobatic, touring, and utility use.[1][2][3] It first flew in 1989 and did not enter production.[1]
Design and development
[edit]The Bushmaster is a high-wing, strut-braced monoplane of conventional design with fixed, tailwheel undercarriage.[1][2] It has two seats, side-by-side, in an enclosed cabin.[1][2] Fuselage construction is of welded steel tube, covered in fabric, and the wing is all metal.[1][2] It is powered by a nose-mounted engine driving a tractor propeller.[1][2] This engine was originally a Norton Aerotor 90 wankel engine, also intended to power production examples.[1][2]
The prototype, VH-BOI, first flew on 28 October 1989.[1][2][3] Certification for the original Norton powerplant was delayed, so it was changed to a Lycoming O-235 after this first flight.[1][2][4] The engine change necessitated some other modifications to the aircraft, including changes to the engine cowling and the undercarriage.[4]
The Bushmaster received its Certificate of Airworthiness in late 1990.[1] Production was to take place at Caboolture Airport.[1] However, by early 1992, Aircorp was under financial pressure, which led one of the original partners in the company, Peter Ferro, to buy it out to continue the project.[4]
By 1992, a range of models had been proposed, and the prototype was modified to make it comply with American FAR 23 regulations in preparation for marketing in the US.[1][2] Production examples were also to have redesigned wing spars, relocated fuel tanks, wings braced with I-struts instead of the V-struts of the prototype, and three-position flaps.[2] Flight testing of the four-seat B4-80 model was anticipated to start in late 1992.[4]
However, by 2007, no further examples had been produced and the prototype was sold off.[1]
