Hello, everyone.

I am very new here and have inquired in the forum about the above engine and could not find anything to my case.

I apologize for my english in advance - i am not a native speaker.

My question is:

Is there any way to get close to the engine manuel (EM) or Cross-Section of an ALF502R-5 engine?

I am a student writing my bachelor thesis on the ALF502 engine. My job is to rebuild the ALF502R-5 engine via 3D CAD (like Siemens NX, SolidWorks etc.), which is precisely the engine, because it was used by NASA for testing purposes at the time.

Keyword: Ice Particle Analysis of the Honeywell ALF502.

However, my job is not to investigate this phenomenon, but to reconstruct the engine, in this case the high-pressure compressor. On the Internet, I can only collect information on how the tests were carried out, but not specific information such as: diameter, length, width. (For example: Impeller, Rotorblades etc.)

I already have an account with honeywell and have access to tech publications, but that’s not always the information I need to rebuild the engine.

If anyone has any tips, I’d be very grateful.

With kind regards,

xSh0keD

Thanks a lot for you feedback.

I cannot use the ALF 502L Engine Manual, because ALF502L version has two-stage low-pressure compressor and the ALF502R version has one-stage low-pressure compressor.

But I have a look about the Lycoming ALF502R Turbofan Engine Student Workbook.

Cheers.

Hi xSh0keD
looks like we have the same issue.
I am currently working on rebuilding the reduction gear and the LPT Module of the ALF502 with CAD.
Could you tell me if you have finally found your informations needed to do your job? Was the Engine student workbook good enough?
Would be very happy for your response

Best regards
