LASER DEVICE OF FUEL COMPONENTS IGNITION (VERSIONS) Russian patent published in 2012 - IPC F02K9/95 

FIELD: power engineering.

SUBSTANCE: invention may be used for multiple start-up of rocket engines (RE) using both liquid and gaseous propellants under conditions of their operation in rockets, spacecrafts and orbital manned space stations, when testing engines on benches. In the first proposed version a laser device for ignition of propellant components in a rocket engine of a space station comprises a vessel with a gas duct - a channel to transport products of propellant components combustion in the space station, units of propellant components supply, a reaction cavity, a laser plug for supplying laser energy into a reaction cavity installed in the device vessel non-coaxially to the gas duct, at the same time the reaction cavity is located in the gas duct, and laser energy is focused at the gas duct wall or into its volume. The second version differs from the first one by the fact that a part of one of propellant components is supplied to cooling a gas duct and is discharged into a combustion chamber.

EFFECT: reliable ignition of rocket propellants in combustion chambers of rocket engines and reduction of electromagnet noise in natural conditions of engines operation.
