JET-PROPULSION PLANTS

Introduced: September 1968

Classification Context

Section:: MECHANICAL ENGINEERING; LIGHTING; HEATING; WEAPONS; BLASTING
Class:: COMBUSTION ENGINES; HOT-GAS OR COMBUSTION-PRODUCT ENGINE PLANTS
Subclass:: JET-PROPULSION PLANTS

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.
