Hello together,

can anyone tell me whether the Nasa Rotor 67 is part of a fan or an compressor?
I found a lot of documentations, but I couldn't find out this fact. I always thougt it is the 1st stage of an LPC...

Thanks a lot.
Greetings.

My understanding is it is a first stage axial compressor as you stated, but the NASA papers call it the first stage of a two stage fan. I'm wondering if this is semantics since the design pressure ratio of rotor 67 is similar to that of other axial compressor stages.

Hi Fishbone,

yes this is exactly what I read, that's why my question. I want to investigate a LPC rotor and I have to be sure that the NASA rotor 67 is one. What about the NASA rotor 37? I think this one is a LPC rotor. If I am wrong correct me please

Greetings
