Hi all,

I'm searching the full 3-D blade geometry of the 2-stage rotor 67 compressor. Or more exactly the full 3-D geometry ot the 2-stage compressor from which the famous rotor 67 has been extracted.

I have the full 3-D blade geometry (in x,r,theta coordinates) of the rotor only. I found it in Strazisar et al. (NASA-TP-2879).

I've been unable to find the same kind of data for the full compressor. I've ordered 2 technical reports from the NASA but the geometry is given with a "throughflow mind" (that is the camber angle at the leading and trailing edge, the maximum thickness). The 2 technical reports are the following :

- NASA TP 1314 : Design and Performance of a 427 -Meter-Per-Second-Tip-Speed Two-Stage Fan Having a 2.40 Pressure Ratio

- NASA TP 1493 : Performance of Two-Stage Fan Having Low-Aspect-ratio, First-Stage Rotor Blading.

Is there another technical report from the NASA that gives the full 3D geometry (in x,r,theta coordinates) ?

Do you know another way to get these informations ?

Thanks in advance

Hello,

Do you have the co-ordinates for the paper "Design and Performance of a 427 -Meter-Per-Second-Tip-Speed Two-Stage Fan Having a 2.40 Pressure Ratio". I have already got the paper but I want the coordinates or any program by means of which I can extract coodinates.

thank you in advance

Regards,
Sagar

Hi, would you have the coordinates for rotor 67?
