Abstract

Experimental investigations of direct laser ignition of non-hypergolic components in model combustion chamber are conducted. Two ways of mounting of laser on combustion chamber are investigated - axial attachment to nozzles head and mounting on lateral chamber surface. Results of experiments with following couples of propellants are described: oxygen-hydrogen, oxygen-methane, oxygen-ethanol, oxygen-70% solution of ethanol in water.

Keywords:

laser ignition, laser breakdown, combustion chamber, nozzles head
