Role
Structures Lead — NEAL Aerospace

Remus is the first motor from NEAL Aerospace, the student rocketry group I co-founded at Georgia Tech. It's a hybrid: nitrous oxide from a ground-side tank into a 3D-printed ABS fuel grain, bolted to a test stand rather than flown. A hybrid can be shut off and can't detonate the way a solid can, which is the right first motor for a small team.

Static fire on Ostia — simulated plume (procedural, not test footage)

As structures lead I own the pressure hardware: the 316 stainless chamber, the bolted closure, the nozzle retention, and the injector plates. The analysis below was run at 350 psi; the motor will likely run higher, so those loads are a floor. The finite-element work found the real weak links early, ten #4-40 injector screws and an aluminium plate with no temper on the drawing, and the flow work in Fluent exists to give the structure honest loads and heat.

Remus is moving through component procurement toward cold-flow and static-fire testing on Ostia.
