A static fire to test a ejection charge baffle system- this was useful because TARC forbids modifications of engines and subsequently ejection charges- at one point in time I was considering a mechanical parachute auto deployment system to ensure we hit the optimal elapse time each launch.  I designed the baffle to protect the electronics that would be used in the system from the ejection charge- a explosion that is normally used to eject the parachute. The hexagonal gas expulsion 0:19 shows the success of this test. The baffle is 2 stage- unfortunately you can't see the first stage that successfully caught all the shrapnel. The biggest triumph was that it held together and diverted the hot gas successfully- no easy task for a structure made of the 3D printed polymer PLA.

A successful pre-COVID launch of the most optimized variant. Consisting of only 4 significant body parts, 3D printing was simple and assembly time was greatly reduced. The addition of a screw in motor mount also helped in terms of re-usability. This launch included an egg which survived intact, encased in a foam core flush with the inner diameter of upper compartment, resting above the altimeter bracket.

This summer, TARC held a Kerbal Space Program Contest- we competed and placed within the top ~10%, and although we weren't first, it was a great exercise in optimization and we had a lot of fun doing it.
