Notes on scope

  1. This sub-class comprises:
    1. combustion product or hot gas turbine plants (steam turbine plants F01K);
    2. internal combustion turbines or turbine plants;
    3. turbine plants in which the working fluid is an unheated, pressurised gas (special vapour plants F01K).
  2. In this sub-class, the term "gas-turbine plants" covers all the above subject-matter and it additionally embraces features of jet-propulsion plants common to gas-turbine plants.
