METHOD OF PRESSURE GASDYNAMIC STABILISATION IN PILOT ENGINE CHAMBER WITH SOLID-PROPELLANT CHARGES WITH HIGH COMBUSTION RATE SUSCEPTIBILITY TO PRESSURE Russian patent published in 2008 - IPC F02K9/96 

FIELD: rocket manufacturing.

SUBSTANCE: method consists in producing an additional source of combustion product depletion by introducing a simulating charge with a low susceptibility of the combustion rate to pressure into the pilot engine chamber. The simulating charge features the combustion product temperature equal to that of the rocket solid-propellant charge combustion products and the exponent in the combustion rate law meeting the requirement to be protected by this invention.

EFFECT: simplifying the pressure stabilisation in the pilot engine chamber with a rocket solid-propellant charge combustion rate susceptible to pressure, and reducing the costs of the equipment required for pressure stabilisation.
