Rocket engines encompass the design and manufacture of propulsion systems for launch vehicles and spacecraft, covering liquid-propellant engines using cryogenic propellants such as LOX/LH2 and LOX/RP-1, solid-rocket motors (SRMs) employing cast composite propellant grains, and hybrid configurations, together with associated turbopumps, combustion chambers, regeneratively cooled nozzles, and thrust vector control (TVC) systems.
