Boring post but to be used as personal reference Liner dimensions:1629 x 300mm. Width of liner: In general the liner is constructed with a 20% overlap. Hence: pi x ID of the casing x 1,2 = 301mm = approximate 300mm wide. Length of liner: Depending on chamber length but chamber length usually is grain stack
Ground testing of the deployment charges of the 86mm minimum diameter GIGA rocket. “Test what you fly, fly what you test”.
A 3D printer camera shroud for the Mobius Mini was ordered from Additive Aerospace. However upon closer inspection I noticed the design could be optimized a bit for the GIGA rocket being: The Additive Aerospace camera shroud used four screws positioned in a square to secure the shroud to the airframe. This is particularly hard to
Pull pin Consisting of two-piece pin where as one part can remain in the rocket during preparations and a second part containing the “remove before flight” tag can be screwed on/off during assembly. With the Intimidator 5 we noticed that a protruding pull pin, especially in combination with parts / coupler pieces which need to slide into each other,
I have been busy with the electronics or avionics bay. I find it one of the hardest components to design properly so little physical progress to report. However I want to share the following picture of goodies I received over the last week. From left to right: Electronics bay update with preliminary routing of the cables.
Need a good reason to thoroughly clean your lathe? Try machining some graphite. A good shop vacuum cleaner such as a wet /dry Karcher helped a lot in keeping the mess to a minimum. However it showed over time that it was unavoidable that, after machining a full graphite nozzle, the entire lathe was covered in graphite particles. I had
One week, one part. The nozzle retainer will hold the full graphite nozzle in place. It is a variation on the simplest form of a retaining ring as used earlier on the KILO 6G motor. The variation consists of: the nozzle retainer has a divergent section where it lengthens the actual divergent section of the
Finished the casing today. It is 1780mm long and will hold 12 BATES grains. Important factor in long rockets is that all parts being properly aligned. To facilitate this all the tubes (casing, airframe & nose cone) rest on square faces. As I didn’t want to rely on the squareness of the band saw cut I had
After having loads of fun with the Wildman – Intimidator 5 it is time for a new experimental rocket. A minimum diameter rocket for some serious altitude. Based on the very succesful KILO 6G motor with a higher total impulse, more grains and updated with a light weight 86x3mm motor casing. Rocket will be made “sustainer-ready” similar like de DECA
