nowhere near enough fuel flow!...it was a stinking hot day and without provision oil cooling we didn't have enough time between runs to let her cool down, the pump couldn't flow enough oil to get the pressure high enough - on run 2 it dropped to below 10psi with combustor pressure at P2 we were in the danger zone of gasses pushing back though the bearings, could've made a last run but bowed out to save an explosive deconstruction!
nice one nick, a inspiration to us all!! most jet engine gokarts started being built,after seeing you on scrap heap challenge,never thought that a diy gas turbine could be put to such good use...
Why wouldn't the afterburner work on Scrap Heap Challenge.
It was sad that it failed in the end. Was it an oil pump failure?
