Aérokit Industrie Aérokit

A side-by-side two-seat single-engined high-wing monoplane with conventional three-axis control. The wing has unswept leading and trailing edges, and constant chord; T-tail. Pitch control is by elevator on the tail; yaw control by fin-mounted rudder; no separate roll control (roll control by one-third span spoilers optional); control inputs through stick for pitch/yaw (optional: stick for pitch/roll and pedals for yaw). Wing braced from above by kingpost and cables, from below by cables; wing profile single-surface. Undercarriage has three wheels in tricycle formation with additional tailskid; no suspension on any wheels (optional torsion-bar suspension on main wheels). No ground steering. Optional brake on nosewheel. Aluminium-tube framework, without pod. Engine mounted below wing driving pusher propeller with V-belt reduction.

With a configuration very close to that of the Quicksilver MXII, this Aerokit was only at the prototype stage in 1982. Conceived by Olivier Richard and built with the assistance of Hugues Delebard and Christian Risbourg, this machine is a direct result of experience acquired with other microlights used within the framework of one of the first private flying schools to appear in France, the Cenpre National de Formation ULM at Rustrel, Vaucluse, founded and directed by Serge Pellenc.

The Aerokit can be used either as a two-axis control machine with elevators and rudders or as a conventional three-axis control aircraft by the addition of spoilers, which are optional. Supplied with a central stick, this side-by-side two-seater machine can be converted to single seat without any difficulty, as the seats are fitted with Velcro, permitting removal of one seat and the re-positioning of the other in the central location. The experience accumulated in the flying school by this manufacturer caused it to fit a wide-track undercarriage which is specially reinforced. The axle of the main wheels is made of 1.6 x 0.9 inch (40 x 2.5 cm) Duralumin tube with internal bushes and nylon-bearing hubs. As an option, the main wheels can have torsion-bar suspension.

The Aerokit in its standard version is fitted with a single fuel tank but this can be increased as an option by fitting two supplementary tanks of the same size, tripling its range. The Aerokit is trailer transportable.
