New Nozzle for the Hypersonic Shock Tube

Monday, June 30th, 2014

We just received the new nozzle for the shock tube from the 3D print house. We designed it but it needed laser lithographic instead of conventional printing so we had it printed by Shapeways. The shock tube runs at mach 2.2 now. The new nozzle will get it to Mach 3. After that we’re putting an expansion chamber on the end that will get it running at Mach 4.

Three Flights, Lots of Research

Sunday, June 29th, 2014

On May 4th we flew three high altitude missions. We carried 800 PongSat student experiments and ten MiniCube payloads. We also conducted ATO engine and flight control experiments and telemetry experiments.

All the flight went really well. One balloon didn’t go as high as we wanted but we still exceeded all the mission objectives.

Here’s the altitudes:

Away 97:   98,944 feet
Away 98:   67,011 feet
Away 99:   103,337 feet
It took a couple of days but all vehicles were recover safe and sound. Nearly 900 people had experiments, projects or some kind of payload aboard the three flights.
