Have a look at this great video of our "HEROS 3" hybrid sounding rocket launch!
This flight to 32300 m (~106000 ft) set a new altitude record for European student/amateur rockets and a world altitude record for hybrid student rockets!

After carefully evaluating the onboard data from last week’s HEROS 3 flight, we can now happily confirm the maximum flight altitude of 32300 m. This sets a new record for European student and amateur rocketry which was held until now by Delft Aerospace Rocket Engineering and their rocket Stratos II.
Furthermore, to our knowledge this is also a new altitude world rocket for hybrid rockets built by students. The maximum speed of HEROS 3 was 2600 km/h with a Mach number of 2.3. The drogue parachute deployed at Apogee as intended and the rocket safely descended to the ground, where the main parachute opened and the rocket landed softly without any damage in 20 km distance to the launch pad.


The launch angle of HEROS 3 was at 80°, which is quite low, since experimental rockets are subject to higher safety requirements at the European Space and Sounding Rocket Range (ESRANGE). Additionally the rocket was only filled to about 70% of the tank volume with oxidizer. The reason for this is that we wanted to make sure with the flight of HEROS 2, that the rocket structure can sustain the high thermal and mechanical loads of supersonic flight. Unfortunately HEROS 2 was not sending any flight data and could not be recovered. Therefore, we decided that also HEROS 3 should not be filled to its maximum level to make the flight as safe as possible. According to analyzed flight data form HEROS 3, a higher launch angle and a fully filled tank would enable a maximum flight altitude of up to 50 km.

Currently the team is busy with processing all the data and video recordings. We proudly present a first, short glimpse on our onboard camera footage in the above video. More video material is currently processed and also flight data graphs will be released in the coming days.

On Tuesday 8th November 2016, 10:30 LT, -18°C: our HEROS 3 rocket was launched from ESRANGE, Kiruna. At almost perfect weather conditions and great visibility it reached an apogee of over 30 km according to telemetry data and was successfully recovered with the drogue and main parachute being released. Further flight analysis is ongoing and awesome on-board video data will be released soon. Below is an on-board picture made at apogee of the flight and a group photo with the rocket after the flight!

HEROS 2 Lift-off

After one tough week with a lot of work, our HEROS 2 hybrid sounding rocket was launched from the MRL launcher at ESRANGE Space Center in Northern Sweden on 31st October 2016 at 12:00 UTC. The countdown went very smoothly: The tank filling with nitrous oxide was quickly done, the heating system both at the GSE and at the launch rail with the air-heated styrofoam box brought the nitrous oxide to the right temperature for launch, despite the cold and freezing outside temperature. The ground and on-board electronics worked flawlessly during the countdown. A lot of great video material of the lift-off and the ascent into the clouds was produced and will be presented in the near future.

However, an electric interference right at the zero time of the countdown caused a failure of the on-board electronics and telemetry system. Without a telemetry signal it was not possible to get any information about the position during and after flight of HEROS 2. We did a detailed analysis and were successful in identifying the failure that occurred. Now we are waiting for the approval of our HEROS 3 launch, which could be on Tuesday or Wednesday.

On the 24th October 2016, our launch campaign of HEROS will start at the European Spaceport Esrange near Kiruna in Northern Sweden. The HyEnD, team consisting of 13 students of aerospace and electrical engineering, worked very hard in the last months to finish all the preparations for our rocket launch.

This year’s launch campaign is very special, since HyEnD managed to prepare two rockets, HEROS 2 and 3, to reach our ambitious goals of more than 20 km flight altitude. Yesterday the transport of our rockets and ground equipment left our facility and is now travelling on the road and sea to Sweden. During the last year of intense work HyEnD improved several subsystems of the hybrid rocket HEROS and the ground support equipment. The on-board measurement and data acquisition system was improved and expanded by several temperature and pressure sensors. This will allow us to monitor the oxidizer loading and propulsion system performance with high precision. This improvement was a necessary step to avoid the problems caused by low nitrous oxide temperature during the launch last year.
Due to new hardware the parachute system enables a bigger functional envelope. For example the drogue parachute can be operated at supersonic speeds.
An improved Power Control and Distribution Unit (PCDU) increases the reliability and functional flexibility of our telemetry unit and on-board camera system. The PCDU also activates the new payload for both HEROS launches. The MIRKA-HyEnD experiment is provided by the KSat student group of University of Stuttgart. It will conduct atmospheric and flight path data measurements and transmit them via satellite and provides also a tracking beacon. KSat will use the data to verify the functionality of their electronic system for future reentry missions.
Additionally the ground support equipment was enhanced with our own heating system which is necessary to keep the nitrous oxide temperature within operating conditions in the cold environment of North Sweden. The oxidizer loading process and hence the countdown could be shortened by including two large reservoir tanks for the oxidizer provided by STAKO, Worthington Industries. A remote controlled camera surveillance system will allow us to monitor and film the launch from different angles around the launch pad.
Now we are excited and highly motivated for our launch campaign this year and we are looking forward to working together with the professional Esrange launch personnel.
