 F02
COMBUSTION ENGINES (cyclically operating valves therefor, lubricating, exhausting, or silencing engines F01); HOT-GAS OR COMBUSTION-PRODUCT ENGINE PLANTS
 F02K
JET-PROPULSION PLANTS (nozzles in general B05B; arrangement or mounting of jet-propulsion plant in land vehicles or vehicles in general B60K; arrangement or mounting of jet-propulsion plants in waterborne vessels B63H; controlling aircraft, flight direction, or altitude by jet reaction B64C; arrangement or mounting of jet-propulsion plant in aircraft B64D; plants characterised by the power of the working fluid being divided between jet propulsion and another form of propulsion, e.g. propeller, F02B, F02C; features of jet-propulsion plants common to gas-turbine plant F02C)
 F02K

Note(s)

  1. Attention is drawn to the notes preceding class F01.
  2. In this sub-class, the term "jet-propulsion plants" means plants using combustion to produce a fluid stream from which a propulsive thrust on the plants is obtained on the reaction principle.
