RE: Does your club noise test turbine jets?
David
You should read the BMFA Handbook which has a special section that relates to model gas turbines.
This states:-
Although the gas turbine is in scientific terms and internal combustion engine it is the BMFA's contention that the DoE Noise Code should not apply to it. The reason for this is that the noise code was written to cover the types of model i/c engines that were known at the time. i.e. piston engines and the concept of gas turbines was not even considered.
Read the rest of the section for more information.
