The build

How it was made.

Osiris introduced two firsts for the team: functional airbrakes, and a student-designed flight computer that had already been flight-tested before competition, so we could fly it as a backup with confidence. The 101.6 mm (4 in) minimum-diameter airframe used fiberglass tubes rolled in-house, with carbon fibre tip-to-tip fin layups. It flew on a CTI O3400 (21,062 N·s), the most powerful motor in team history. Blue Raven flew as primary with Void Lake as SRAD backup, logging an apogee within 23 ft of the published figure. Dual-deploy recovery fired drogue near apogee and main at 1,373 ft AGL. Peak velocity was 642.5 m/s (Mach 1.92 at burnout).

Build the next one

We hire first years.

We hire people who have never touched a rocket. Come ready to learn. We'll teach the rest.

Find us at Facultyfest on August 31, 12:30 to 17:00, or Clubsfest on September 14, 16:30 to 19:30 on the JHE field. Applications close September 18. You don't need to be an engineer: we need people on operations as much as on airframe.
