Бёрт Рутанның екі қанатты ұшағы: Quickie моделі

Light aircraft designed by Burt Rutan

The Rutan Model 54 Quickie is a lightweight single seat taildragger aircraft of composite construction, configured with tandem wings. The Quickie was primarily designed by Burt Rutan as a low powered, highly efficient kit plane. Its tandem wing design has one anhedral forward wing and one slightly larger dihedral rear wing. The forward wing has full span control surfaces and is thus similar to a canard wing, but is considerably larger. The aircraft has unusual landing gear, with the main wheels located at the tips of the forward wing.

The Quickie Aircraft Corporation was formed to produce and market the Quickie in kit form after 1978. Two years later a two seater variant of the same layout followed as the Q2. The original Quickie (Model 54 in Rutan's design series) is one of several unconventional aircraft penned by Rutan for the general aviation market. The Quickie followed from Jewett and Sheehan's intention in 1975 for a low cost, low power, single seat homebuilt aircraft. The first element to be found by Jewett and Sheehan was the engine, which – although low powered (they had anticipated 12 hp) – had to be reliable for aviation work. With the help of Onan, a manufacturer of industrial four stroke engines, they were able to procure a engine that would deliver 18 hp (14 kW) at 3,600 rpm. Rutan was then involved with the design; Sheehan and Jewett suggesting a scaled down Vari Eze. After a preliminary pusher canard configuration design (Rutan Model 49) had been discarded, Conversely to canard layout, the conventional front engine location put the pilot close to the center of gravity, a key point for a light aircraft. The wheels were incorporated into wingtip fairings without much drag penalty and the tandem layout gave safe stalling characteristics. After the first flights, Rutan spent more time with his Defiant design and other projects, and it was Jewett and Sheehan who continued development of the design and market it for home build use.

The Quickie is a tandem wing taildragger, having one forward wing and one rear wing (instead of the more usual main wing and tailplane). According to Rutan this layout was not new, having previously been used in aircraft such as the Mignet "Flying Flea". provides positive lift from both pairs of wings; whereas on a conventional aircraft, the tailplane mostly provides negative lift. The Quickie has fixed (non retractable) main wheels faired into spats located at the tips of the forward wing. The absence of separate landing gear helps to reduce both weight and drag,

Construction of the prototype commenced in August 1977 at the Rutan Aircraft Factory; Originally designed with a fixed fin and only the faired tailwheel acting as the rudder, a conventional rudder was substituted. The steerable tailwheel allows directional control up to the point of liftoff, as the Quickie does not lift its tail during the takeoff run. Although it takes off at around 55 mph and its maximum speed of 126 mph is impressive for its engine power, the rate of climb is "modest". The flight test program was completed in mid April 1978, five months after its first flight.

In June 1978, only two months after the prototype's first flight, Jewett and Sheehan formed the Quickie Aircraft Corporation to produce and sell complete aircraft kits. Production began in June 1978, and by 1980 the Corporation had sold 350 kits. Other firms were granted marketing rights, and ultimately some 1,000 Quickie kits were sold. The Corporation closed its doors in the mid 1980s.
