A problem with my HobbyKing Pulsejet
Unfortunately, there seems to be a problem with the "flowjector" on my HobbyKing pulsejet.
Instead of directing the spray of air and fuel down the inlet tubes, past the valves and into the combustion chamber, the angles are such that the fuel hits the venturi then runs out the front of the engine.
Despite having plenty of air pressure, fresh fuel and a good spark, the engine barely managed a couple of very weak pops and when I removed the valve-head it was still bone-dry inside.
I will investigate further and probably make up my own flowjector with better geometry before trying again.
I see that NightFlyyer has a similar problem attempting to get his engine to run in this video:
Stay tuned, the engine will be running shortly.
