mabuse00 Posted July 21, 2024 Posted July 21, 2024 I cannot get my hands on them easily since they are class 4. The seem to use a rather large caliber endburning driver, >25mm But I'm curious: What caliber are they? Or at least, what's the outside diameter of the aluminum tube? Do the use a short core, like many endburners do?
Kalifireworks Posted July 22, 2024 Posted July 22, 2024 (edited) They use a very short core, maybe arround 1cm high. Since they use a Aluminium tube there is no clay plug, so it is indeed like a very short core. Edited July 22, 2024 by Kalifireworks
mabuse00 Posted July 22, 2024 Author Posted July 22, 2024 Every endburner needs a very short core to reach the average thrust right from the start. Judging from the pictures this seems to be the case here... with a little boost for liftoff maybe... Also judging from the pictures the nozzle ist quite large. It looks like 1/3 ID or so, more like a fountain... But does anyone know the diameter for a large 930 type motor?
a_bab Posted July 22, 2024 Posted July 22, 2024 I may get my hands on some and I will dissect for reference. But this may not be before Autumn.
