Testing spray pattern on turbine injectors
I'm in the middle of cleaning the injectors of the engine on my BD-5J, and I
was wondering if someone here has dealt with this issue before... I need to test spray pattern. The engine has 8 injectors. I know I can set up a rig where I pump fuel into the injectors, and perhaps use a piece of cardboard 12 inches from the injectors to see what the spray pattern looks like after a shot of fuel. I would be looking for uniformity of pattern from all injectors. Am I missing something else I should look for? Juan -- Posted via a free Usenet account from http://www.teranews.com |

Juan Years ago while in the USAF as a jet engine mechanic we used a stand where the nozzles were screwed into a fixture vertical with a clear Plexiglas panel over the nozzles approximately 6" which allowed us to inspect the spray pattern, if one was off we immersed the injector in a de carbon mixture and retried the pattern. One thing that you should remember is the injector tips are fragile, if you must attempt to remove any hard deposits use a orange stick or a tampico brush. Good luck, please remember this is how it was done in the 60's perhaps a newer and better method has been devised |
