Updated 21/6/2017: At posting the team uploaded a video of their 4th test of the engine, which judging from the team’s reaction was a success!
Video Caption: The Stratos III propulsion team was facing some issues when the engine got a burn through after the first two tests. Check out this third engine test video and see for yourself with what engine we want to take back the altitude record!
In this video summary, you can see the three tests performed by Project Phoenix: The hybrid engine team within DARE. The engine fired in test 1 shows a thermal failure at 5.6 seconds. Engines fired in test 2 and 3 show a successful burn.
As reported earlier, DARE have begun testing of their hybrid rocket engine for their Stratos III rocket.
The engine burns an 80/10/10 Sorbitol-Paraffin-Aluminium fuel mix with nitrous oxide as the oxidiser.
Delft Aerospace Rocket Engineering students recently rolled out their new rocket, Aether. Designed to be actively stabilised during supersonic flight, the rocket represents a great leap forward for the team and their active control quest.
Not specifically designed for altitude but for control ability through different flight regimes, Aether sports the teams Asimov solid rocket motor. Developing an average thrust of 6464N for 6 seconds, the motor makes up 1.5m of the airframe and uses 35kg of propellant.
Control comes from 4 forward mounted canards, with control output coming from the onboard XSENS IMU. Instead of a typical blow the nose cone of recovery, the recovery of Aether will involve the deployment of the drogue and main chute from a hatch in the side of the rocket, providing a reliable means for recovery at the velocities and dynamic pressures encountered.
I could keep going on, so instead, head over and check out the team’s technical page and you can read the full roll out update here.
The launch is currently planned for the 29th of April.
