F02K JET-PROPULSION PLANTS (features of jet-propulsion plants common to gas-turbine plants, air intakes or fuel supply control of air-breathing jet-propulsion plants F02C7/00, F02C9/00)
Description
F02K covers jet propulsion systems and related powerplants that generate thrust through the expulsion of high-velocity fluid jets. This subclass encompasses gas turbine engines, ramjets, scramjets, pulse jets, and rocket motors used for aerospace and marine applications. The classification includes combustion chambers, fuel injection systems, nozzle designs, and thrust vector control mechanisms integral to jet propulsion. Adjacent classes F02C and F02D address gas turbines and fuel injection systems in non-jet applications, while F02B covers reciprocating internal combustion engines.
