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.
Gas-turbine plants characterised by the working fluid being generated by intermittent combustion
F02C 5/02
·
the combustion chambers being associated with the turbine or compressor
F02C 5/04
· ·
the chambers being formed at least partly in the turbine rotor
F02C 5/06
·
the fluid being generated in combustion apparatus of the positive-displacement type having essentially no mechanical power output (internal-combustion engines of the positive-displacement type with prolonged expansion using exhaust gas turbines Fulltext... Hierarchy... Expanded...F02B)
F02C 5/08
· ·
the apparatus being of the free-piston gas-generator
