We are assembling the prototype 2. We expect to have it done by the end of week 10

We have finished the fabrication of the hybrid engine mold. We expect to finish the composite hybrid engine by the end of week 10

This is the design of rocket flight control and recovery system. It is similar to the platform avionics, but due to the size limit, this system use CDMA (Verizon) as secondary recovery system. The platform avionics uses SPOT Trace as backup recovery system

After we lost the first avionics system, we add a solar panel and a commercial recovery system to the platform. We use battery with larger capacity.

This avionics will be used in Rockoon platform and Rocket in the future. During the test, due to the high wind speed, the system continuously output attitude warning signal, and this caused the battery die much faster than our design.

We did the preliminary analysis of the high altitude balloon test. The balloon flight path matches the University of Michigan’s predictor. However, we only searched the landing zone predicted by Cambridge University.

We finally finish the fabrication of injector plate. Cold flow test looks good

We conducted the first major test on April 17th. We lost the communication with balloon thirty minutes after launch.

The hybrid engine mold is ready for use. We will have a fiberglass prototype of hybrid engine by the design review
