David and I dismantled the Kerosene rocket yesterday, and (as usual) cut the fuel grain along its length.
Having given every component a thorough check we can report:
No damage, blistering or heat effect was observed on any of the metal parts of the rocket.
The fuel grain had burned evenly along almost its entire length. The inner liner was only half consumed (which is less burning of cardboard than any previous rocket).
If you watch the video carefully you'll see the rocket shut down very quickly - this is because the movement caused the safety solenoid to shut down. I must emphasise that nobody was put in harm's way.
Someone, posing as Tog from Eurodragster, made some very disparaging comments on Youtube. We know who this person is, he has been conducting a very sad hate campaign for several years. The comments have been removed.
Conclusion: A very repeatable rocket!!
