Encased in a basic fairing which could hold fuel and remote-control equipment, the unit weighed 5,600 pounds (2,500 kg), and generated a thrust of approximately 6,200 pounds-force (27.6 kN); the Atar Volant was able to cause vertical lift, which was precisely its purpose.
There were later Atar Volant models, each made improvements and alterations to the previous designs, and eventually resulted in a full-fledged craft.
However, the design of the Coléoptère met with many problems, such as overcoming the torque imparted to a vertical engine by its own turbine wheels and rotating compressor, and discovering and developing a method of balancing the craft on the column of air released from its jet pipe during the take-off and landing phase, as well as, more particularly, during manoeuvres out of the vertical positioning.
To address some of these problems, as well as to provide a way to achieve vertical lift, SNECMA set to work on what was to become the first model of the Atar Volants.
The second in the series had much success at an international air display in Le Bourget, in Paris, and the third became a full-scale coleopter in its own right, due to numerous improvements and alterations made to the model.
