The Wombat Gyrocopters Wombat, sometimes called a Julian Wombat, is a British autogyro that was designed by Chris Julian and produced by Wombat Gyrocopters of St Columb, Cornwall, introduced in 1991. Now out of production, when it was available the aircraft was supplied as a kit for amateur construction. [1]

Development

Julian was known as a motorcycle speedway racer. He decided to design his own autogyro and on 4 November 1991 the CAA issued the Wombat a restricted Permit to Test. It was test flown at the St Merryn airfield in Cornwall. In May 1997, when Julian was 60 years old, he was killed in the crash of a different model gyroglider at the Kemble airfield. [2]

After Julian's death the Wombat design rights passed to former helicopter pilot Mark Harrisson in July 2000. Harrisson had intended to put the aircraft back into production, but in 2013 instead donated the prototype to The Helicopter Museum in Weston-super-Mare, where it arrived on 9 July 2013. [2] [3] [4]

Design

The Wombat was designed to comply with the British Amateur-built aircraft rules. It features a single main rotor, a single-seat semi-enclosed cockpit with a cockpit fairing and windshield, tricycle landing gear, plus a tail caster and a twin cylinder, air-cooled, two-stroke, single-ignition 64 hp (48 kW) Rotax 532 engine in pusher configuration. [1]

The aircraft fuselage is made from bolted-together aluminum tubing. Its two-bladed Dragon Wings aluminium rotor has a diameter of 22.83 ft (6.96 m), including a 2.53 ft (0.77 m) hub bar. Rotor cyclic control is via torque-tubes. The rudder is constructed with a composite skin over a foam core. The aircraft lacks a horizontal stabilizer. [1] [2]

The Wombat has a typical empty weight of 352 lb (160 kg). The standard day, sea level, no wind, take off with a 64 hp (48 kW) engine is 300 ft (91 m) and the landing roll is 3 ft (1 m). [1]

Operational history

In April 2015 no examples were registered in the United Kingdom with the CAA. Although a total of four had been registered at one time, all have had their registrations cancelled by the CAA. [5]

Autogyro Rotorcraft with unpowered rotor

An autogyro, also known as a gyroplane, is a type of rotorcraft that uses an unpowered rotor in free autorotation to develop lift. Forward thrust is provided independently, by an engine-driven propeller. While similar to a helicopter rotor in appearance, the autogyro's rotor must have air flowing across the rotor disc to generate rotation, and the air flows upwards through the rotor disc rather than down.

Bensen B-8 Small, single-seat autogyro

The Bensen B-8 is a small, single-seat autogyro developed in the United States in the 1950s. Although the original manufacturer stopped production in 1987, plans for homebuilders are still available as of 2019. Its design was a refinement of the Bensen B-7, and like that aircraft, the B-8 was initially built as an unpowered rotor-kite. It first flew in this form in 1955, and on 6 December a powered version, designated B-8M first flew. The design proved to be extremely popular and long-lasting, with thousands of sets of plans sold over the next thirty years.
