Review of ejector nozzles. Part 2 – Mixers and additional information

open access: yesАвіаційно-космічна техніка та технологія
The subject of this article is ejector nozzles, which are intended for the thrust augmentation of jet engines and their corresponding flow mixers. The goal is to soften the acuteness of contradictions between the required high performance (especially ...

Flight velocity effects on exhaust noise of a wedge nozzle installed on an underwing nacelle on an F-106 airplane [PDF]

open access: yes
It is important to know whether the relatively high takeoff speeds of supersonic transport aircraft will change the exhaust noise levels of nozzles from those measured at static conditions.

On the use of relative velocity exponents for jet engine exhaust noise [PDF]

open access: yes
The effect of flight on jet engine exhaust noise has often been presented in terms of a relative velocity exponent, n, as a function of radiation angle.

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 ...
