I have scavenged a second hand turbo and built a jet engine. Very easy to get spooling and runs well but I keep getting flame escaping past the exhaust turbine and then get flame out. It's a waste gated turbo specked to open the waste gate at 8 psi which I can't spool it enough to get to happen...
Not quite. While the injector is still operating on pressure created by the cam driven pump the forth cam operates the opening. This way fuel is under pressure before the injector is allows to open instead of relying on a ball valve to hold pressure to a point before opening. This way fuel is...
Can I make stupid suggestion. Build your cam with four lobes. One for intake one exhaust one for driving injector and one that holds injector closed until firing. The lobe will work opposite to most cam lobes but ensures no leakage until up resource is right and allowed to open. Instead of a...
Trying to build a jet turbine. So far attempt one fired but failed to drive turbine. Attempting lighter weight turbine but just wondering what are the best angles for exhaust and compressor blades
