F02K 3/04

the plant including ducted fans, i.e. fans with high volume, low pressure outputs, for augmenting the jet thrust, e.g. of double-flow type

Introduced: September 1968

Title

Titles differ between systems:

IPC: the plant including ducted fans, i.e. fans with high volume, low-pressure outputs, for augmenting jet thrust, e.g. of double-flow type

CPC: the plant including ducted fans, i.e. fans with high volume, low pressure outputs, for augmenting the jet thrust, e.g. of double-flow type

Full titles differ between systems:

IPC:

Plants including a gas turbine driving a compressor or a ducted fan > in which part of the working fluid by-passes the turbine and combustion chamber > the plant including ducted fans, i.e. fans with high volume, low-pressure outputs, for augmenting jet thrust, e.g. of double-flow type

CPC:

Plants including a gas turbine driving a compressor or a ducted fan > in which part of the working fluid by-passes the turbine and combustion chamber > the plant including ducted fans, i.e. fans with high volume, low pressure outputs, for augmenting the jet thrust, e.g. of double-flow type

IPC and CPC are identically structured here. All 7 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.
