Last pulsejet test before the race
Successful run of the new Thunderchine design
Those of you who sat banged in front of the live broadcast today was unfortunately not directly value for money then the sound was missing and the places where the right choppy picture of witness testimony, but it was a nice attempt and the next time we try us on something like this, we will be sure to get fjong little better at it. Bjursingen have a right from the webcam that rotates automagically so there are resources you should know!
Anyway, it became the test start and everything flowed relatively undramatic, a leaking fuel coupling and a little unbalanced at certain speeds must be corrected and a new oil pump to be built when the old diaphragm pump is to drop the oil up the pressure when the oil gets hot.
I was on 2.2bar boost at most so it is little more to get before I reach the MAX RPM on 70.000rpm, unfortunately fell reflective tape to the tachometer off from the compressor wheel at 2 bar so I did not dare to relax more. Thanks to the new tighter O-ring of the motor housing does not leak air mass fell exhaust the temperature 60-70 ° C compared with before, so now I can close up jetdysan right good before I reach maxtempen at 750 ° C, thus gaining mass more thrust!
It's a small list of Things To Do-stuff this time too, luckily it's only improvements and no repairs after last run ... =)
