F02K 7/10

characterised by having ram-action compression, i.e. aero-thermo-dynamic-ducts or ram-jet engines

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Plants in which the working-fluid is used in a jet only, i.e. the plants not having a turbine or other engine driving a compressor or a ducted fan; Control thereof > characterised by having ram-action compression, i.e. aero-thermo-dynamic-ducts or ram-jet engines

CPC:

Plants in which the working fluid is used in a jet only, i.e. the plants not having a turbine or other engine driving a compressor or a ducted fan; Control thereof (rocket-engine plants F02K9/00) > characterised by having ram-action compression, i.e. aero-thermo-dynamic-ducts or ram-jet engines

Of 6 combined children, 5 exist in both systems.

1 codes are CPC-only extensions.

IPC defines codes here since 1980.
