// PROPULSION SYSTEMS AND ENGINE TECHNOLOGY TERM
Thrust Chamber
The thrust chamber is the main part of a rocket engine where propellants are mixed and ignited, burning at high pressure to produce hot gases that are then expelled to generate thrust.
TECHNICAL DEFINITION
The thrust chamber is a critical component within a rocket engine where propellants (liquid or solid) undergo combustion, converting chemical energy into thermal energy to produce high-temperature, high-pressure exhaust gases that are subsequently directed through a nozzle to generate propulsive force.
BACKGROUND
Spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites. In-space propulsion is used in the vacuum of space after launch vehicle has lifted the spacecraft into outer space.
