A theoretical engine for reaction propulsion, based on gas generators that could be single or double with free pistons.

-It has discs around the pistons that sent a large amount of air to additional chambers where a second and third combustion takes place.

“Single and double Schurter engine”

-In addition, two or three air generators could be coupled in parallel, feeding the general collector of the supplementary chambers.

“Schurter system”

-This pressurized air could be directed to increase lift or to act as anti-icing or de-icing of control or lifting surfaces.
