Prediction of axial-flow instabilities in a turbojet engine by use of a multistage compressor simulation on the digital computer [PDF]

open access: yes
A method of estimating the undistorted stall line for an axial-flow compressor by using the digital computer is presented. The method involves linearization of nonlinear dynamic equations about an operating point on a speed line, and then application of ...

Sonic inlet noise attenuation and performance with a J-85 turbojet engine as a noise source [PDF]

open access: yes
A static test program was conducted to investigate aerodynamic and acoustic performance of a sonic inlet used as a noise suppressor. A translating centerbody type inlet with radial vanes was tested ahead of a J85-GE-13 turbojet engine.
