The Avisud Sirocco is a single-seat ultralight available in kit or fully-assembled form and originally produced by Aviasud Engineering in 1983. It is of pod-and-boom design with tricycle undercarriage and pusher configuration. The fuselage is of composite construction. In 1984, one was flown by Patrice Franceschi in a circumnavigation of the earth.
In 1989, manufacuture transferred to Aériane in Belgium. In 2007, the rights to the Sirocco were acquired by ACLA — Aero Consult Light Aircraft, who have redesigned the tailplane and wings and are re-launching the aircraft as the Sirocco NG. The first flight of the prototype for this was in May 2009. See also the ACLA Sirocco blog.
The Sirocco NG is available as a kit, or in its lighter version (FAR 103/SSDR) fully built.
Description
The aircraft has two wings which can be dismounted for transport. The leading edge box consists of a spar and fibreglass leading edge, supplemented by an alloy rear strut. The wing profile is defined by preformed aluminum ribs. The trailing edge spar is laminated fiberglass. These three elements are interconnected by compression rods, cables and ribs, and ensure the shape and tension of the fabric coating for good aerodynamic efficiency. The coating is "Bainbridge" Dacron, 170 gr/m². Once in place on the fuselage, cables and a kingpost stay the two wings.
The fuselage and vertical fin are made of a fiberglass-polyester structure consisting of 2 half shells molded and stiffened by frames and smoothed to have a lightweight structure with an aerodynamic shape. Once completed they are assembled by gluing, which ensures rigidity.
The landing gear is made from glass-epoxy. The main gear is flexible; the front axle is steerable and has a brake drum. The steering control is a lever on the right of the cockpit, with locking in a neutral position.
The motorcycle-type engine may have a power ranging from 24 HP (Koenig 43ORD) to 40 hp (Rotax 447), and is mounted on the rear of the central mast. Starting is manual.
The pilot is in a recumbent position in the cockpit. The canopy is removable; flights are possible without the canopy in hot weather. For the winter there is an electric heater. The pilot is kept in his seat by a 3-point belt; the seat is fixed, but the rudder pedals are adjustable (3 positions) depending on the size of the pilot. The mini control stick is central.
One-piece tailplane (fully mobile/all-flying) controlled by rigid rods and ball joints. A trim tab helps balance the machine at all speeds, to improve comfort for long flights.
