The Fouga CM8-R13 Cyclone is a jet-powered motor glider. It served as a testbed for the Turbomeca Pimene<\/a>. It was quickly assigned another mission: reaching altitudes that were difficult for gliders of the time to attain. <\/p>\n\n\n\n

First flight<\/h3>\n\n\n\n

The Cyclone (Sylphe) made its first flight on July 14, 1949, piloted by L\u00e9on Bourrieau<\/a> who developed all the prototypes for Fouga (\u00e9tablissements FOUGA).<\/p>\n\n\n\n

Two aircraft were produced, which were assigned the following registrations: F-WFOI<\/strong> [F-BFOI] (s\/n 1) and F-WFOJ<\/strong> [F-BFOJ] (s\/n 2),<\/p>\n\n\n\n

A number of changes are noticeable between these two aircraft. In particular, we can observe the wheel mounted on the forward skid in the case of s\/n 2, while it is integrated into the skid on s\/n 1. The engine cowling also underwent modifications.<\/p>\n\n\n\n

Presentation<\/h3>\n\n\n\n

Behind the pilot, sheltered under a streamlined Plexiglas canopy with a flat front section that provides good visibility, the jet engine (PIMENE)<\/strong> .is mounted on a pylon, housed in a streamlined structure<\/p>\n\n\n\n

This simple arrangement ensures good airflow to the turbine. The exhaust of the burnt gases causes no aerodynamic disturbance due to the use of a V-tail configuration.<\/p>\n\n\n\n

The construction of this glider is entirely made of wood, varnished and painted.<\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Wings<\/h4>\n\n\n\n

The wing, with an aspect ratio of 13, features a NACA 23014 airfoil at the root, transitioning to a 23012 at the tip.<\/p>\n\n\n\n

It is a mid-wing, cantilever monoplane type, with a single spar and stressed-skin structure, entirely constructed of wood.<\/p>\n\n\n\n

It features slotted ailerons, as well as slotted trailing edge flaps, all constructed from light alloy and then fabric-covered.<\/p>\n<\/div>\n\n\n\n

\n

Tailplanes<\/h4>\n\n\n\n

It is a V-tail configuration. The fixed surfaces are made of wood, covered with plywood. The movable parts are constructed from light alloy, covered with sheet metal.<\/p>\n\n\n\n

Landing Geard<\/h4>\n\n\n\n

The landing gear is of the monowheel type, consisting of a single wheel and a fixed skid.<\/p>\n\n\n\n

Fuels<\/h4>\n\n\n\n

The Turbomeca Pim\u00e9n\u00e9 turbojet of the Fouga Cyclone (Sylphe) uses kerosene for normal operation and gasoline for startup.<\/p>\n\n\n\n

The kerosene \/ Jet A1 is stored in a 96-liter tank located in the fuselage<\/p>\n<\/div>\n<\/div>\n\n\n\n
