F02C

GAS-TURBINE PLANTS; AIR INTAKES FOR JET-PROPULSION PLANTS; CONTROLLING FUEL SUPPLY IN AIR-BREATHING JET-PROPULSION PLANTS (construction of turbines F01D; jet-propulsion plants F02K; construction of compressors or fans F04; combustion apparatus in which combustion takes place in a fluidised bed of fuel or other particles F23C 10/00; generating combustion products of high pressure or high velocity F23R; using gas turbines in compression refrigeration plants F25B 11/00)

Note(s) This subclass covers: combustion product or hot gas turbine plants;internal combustion turbines or turbine plants;turbine plants in which the working fluid is an unheated, pressurised gas. This subclass does not cover: steam turbine plants, which are covered by subclass F01K;special vapour plants, which are covered by subclass F01K. In this subclass, the following expression is used with the meaning indicated: "gas-turbine plants" covers all the subject matter of Note (1) above and covers also features of jet-propulsion plants common to gas-turbine plants. Attention is drawn to the Notes preceding class F01.
