METHOD FOR TWO-STEP COMBUSTION OF A SOLID FUEL ROCKET ENGINE AND SOLID FUEL ROCKET ENGINE

摘要

The invention relates to a method for the two-stage combustion of a solid fuel rocket motor (4a-g), in which the solid fuel (18) has a first stage (12a-f) in a first subchamber (14) of a combustion chamber (16) with a first ignition unit (22) is ignited and then solid fuel (28) of a second stage (24ag) is ignited (30a-g) in a second sub-chamber (26) of the combustion chamber (16) with a second ignition unit. A simple and safe ignition of the second stage ( 24a-g) can be achieved if combustion of the first stage (12a-f) ignites the second ignition unit (30a-g), the second ignition unit (30a-g) burns solid fuel in a converted burn-through section (44) and this burns the solid fuel the second stage (24a-g) ignites after waiting for the first stage (12a-f) to burn out.
