// 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
Nuclear pulse propulsion or external pulsed plasma propulsion is a hypothetical method of spacecraft propulsion that uses nuclear explosions for thrust. It originated as Project Orion with support from DARPA, after a suggestion by Stanisław Ulam in 1947. Newer designs using inertial confinement fusion have been the baseline for most later designs, including Project Daedalus and Project Longshot.
