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 > the jet being intermittent, i.e. pulse jet > with combustion chambers having valves > having aerodynamic valves

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) > the jet being intermittent, i.e. pulse-jet > with combustion chambers having valves > having aerodynamic valves

No child classifications to compare. This is a leaf node in both IPC and CPC.
