The initial Microturbo product offering was the "Noelle" starter turbine, which led to a number of starter / APUs such as the "Emeraude", "Espandon", and "Saphir". The Emeraude led to the company's first turbojet, the small and simple Eclair, intended for self-launching sailplanes.
Based on the gas generator section of the Microturbo Emeraude starter and APU for Concorde prototypes, the Eclair is an ultra-small single-shaft turbojet designed to power pilot-less drones and for use in sailplanes.
The engine is also capable of in-flight starting to provide powered flight in an emergency. Initial installation was in the Fauvel Aile Volante AV 45-01R single-seat tailless self-launching sailplane which first flew with the Eclair 012-01 in late 1967.
