N₂ORTH Rocket | Its time for launch! Hybrid Engine Development - HyEnD e.V. 2023-04-04 | Stay tuned and follow our launch campaign in Esrange from 11th to 25th April 2023:https://hyend.de/index.php/category/n2orth-launch-campaign/
N₂ORTH Rocket | Final Propulsion System & Loading Procedure Test Hybrid Engine Development - HyEnD e.V. 2022-12-14 | HyEnD has successfully conducted its final system test on Thursday, 8th December! The test included the oxidizer loading procedure using the Ground Support Equipment as well as a hot fire with the hybrid engine and rocket’s fluid system components.During the oxidizer loading procedure, temperatures and pressures were measured across multiple parts of the Ground Support Equipment and 160 L oxidizer tank. We are happy to report that the test showed a high level of precision during the loading procedure, as we were able to precisely set the amount of oxidizer as well as temperature and pressure conditions in the tank.The hot fire of the propulsion system showed stable and efficient combustion throughout the operation time. With a peak thrust of more than 15 kN and a total impulse of 255 kNs at sea level, we are confident that the propulsion system is capable of pushing N2ORTH to the frontier of space. The in-flight impulse of this configuration will be even higher since effects like flow separation will occur later in the operation time due to lower ambient pressure at higher altitudes. Moreover, the test showed good accordance to the simulation carried out in advance. This is especially important to ensure a safe flight trajectory of the rocket.As this was our final hot fire within the scope of the STERN 2 project, we would like to thank the DLR Institute of Space Propulsion for their fantastic support during the last years. Since September 2020, more than 60 hot fires were conducted, and we learned a lot! We are now fully focused on the final production and assembly steps and are looking forward to our launch campaign in April 2023.Music: Overwerk - Canon
N₂ORTH Rocket | Recovery System Sequence Test Hybrid Engine Development - HyEnD e.V. 2022-11-23 | Flying up to 16,000 feet and dropping 79 kg from an aircraft: Under these conditions, we were able to perform the first system test of the entire recovery system of our sounding rocket N2ORTH. By evaluating the drop sequence, we could determine whether all components of the two-stage system work nominally in interaction with one another. At the same time, we wanted to investigate the canopy behavior during deployment in subsonic conditions as well as the integrity of all structural components.Apart from minor design flaws in structural components, the test was completed successfully. Both parachutes withstood the occurring loads and showed a stable descent. The load switch from the drogue the main parachute worked out properly with a nominal main parachute deployment at about 1,000 m above ground. After descending 300 s, the drop test demonstrator landed safely in the designated landing zone of the Heuberg military training area.We would like to take this opportunity to thank all our partners who supported us in the successful realization of this project during the last month. Big thanks to the companies like “LIROS GmbH” (ropes), AMANN Group (yarns), Güth & Wolf GmbH (aramid bands/harness), EDELRID GmbH & Co. KG (shock absorber), Heathcoat Fabrics Limited (drogue parachute aramid fabric) and EVOTEC (main parachute) for providing materials/components together with technical support.Furthermore, a special thanks goes to the German Armed Forces and Skydive Saulgau GmbH for the safe conduction of our test.
N₂ORTH Rocket | Aiming for new heights Hybrid Engine Development - HyEnD e.V. 2022-10-07 | We are happy to share a small teaser for the upcoming reveal and launch of our rocket N2ORTH! In the last three years, the team worked hard to make this rocket a reality. The rocket now is almost ready to launch, with only a few last tests and the assembly ongoing. The launch from Esrange is planned for the first half of 2023. As for the target altitude, we plan to break our own record for student-built hybrids (32.3 km) but N2ORTH is a lot more capable. The target altitude is still subject to change and will be chosen in accordance to our trajectory simulations, safety regulations at Esrange and weather conditions. Stay tuned for more details!
N₂ORTH Rocket | Hybrid Propulsion System Test in Blow Down Operation Hybrid Engine Development - HyEnD e.V. 2022-09-06 | HyEnD is proud to announce that the N2ORTH propulsion system was successfully qualified in a hot fire test for a propellant throughput of more than 100 kg! This marks an important milestone for the project, as we now have a flight-worthy propulsion system for the launch. During the test, the rocket tank was operated in a blow down setup together with the fluid system and engine of the rocket. The ground support system of the rocket was used in order to fill the rocket's tank with nitrous oxide and helium. The test included the main operation phase of the engine and also the gas blow down after the depletion of liquid oxidizer, resulting in an overall hot fire duration of more than 50s. In the upcoming weeks, the team will prepare another test with increased propellant mass in order to unlock the full potential of N2ORTH.Learn more at www.hyend.de
HyLIGHT-2 | 25s Test of 10kN Hybrid Rocket Engine in Near-flight Configuration Hybrid Engine Development - HyEnD e.V. 2022-03-14 | HyEnD is proud to announce that it has tested its HyLIGHT-2 Engine in near-flight configuration for its full intended operation time of 25 seconds. The test was conducted at the test bench M11 of the German Aerospace Center in Lampoldshausen and marks a big milestone for the development of the N2ORTH rocket.The tested configuration has a dry mass of 13.5 kg and was loaded with 20 kg HTPB-based fuel. In addition, 2 kg of HDPE film are located in the post combustion chamber in order to function as a film cooling ablator for the nozzle section. The multi-element swirl injector and graphite mixer in the post combustion chamber ensured a high reaction and overall engine efficiency, resulting in a specific impulse at sea level of 224 seconds. Operating at 30 bar chamber pressure and an oxidizer to fuel ratio of 6.07, an overall impulse of 267064 Ns was achieved. The next test with minor optimizations of the design is scheduled for end of March. This test will be the final static test and will qualify the engine design. For April and May, integrated tests in blow-down configuration together with the rockets oxidizer tank, fluid system and ground support equipment are planned.

Compass Hybrid Rocket - Launch Hybrid Engine Development - HyEnD e.V. 2021-06-29 | On Friday 25th June 2021, HyEnD has successfully launched its subscale demonstator rocket Compass for the DLR STERN project. The launch took place at the Truppenuebungsplatz (military training area) Heuberg. Compass was able to reach an altitude of more than 3200 m / 10,000 ft above ground and an initial acceleration of more than 6.5 g. During ascent, all systems performed nominally. Drogue and main parachutes were ejected– however, the main parachute was not able to unfold, and the rocket landed with a descent rate of about 20 m/s. This resulted in some damage to structural components and the fluid system – but we are happy to inform you that our mascot Major Ted is well and seems to have enjoyed the ride! We want to thank all supporters that have made this launch possible – stay tuned for more details soon!
Compass Hybrid Rocket - Recovery System Drop Tests Hybrid Engine Development - HyEnD e.V. 2021-05-24 | At the beginning of May, the drop test of the Compass recovery system took place. At an altitude of 500m, a dummy with the dry mass of Compass was thrown out of a model aircraft. The drogue chute decelerated the dummy down to 26 m/s and the main chute to 3.3 m/s. The parachutes had already been tested in the IAG wind tunnel and the drogue parachute ejection system on the ground a few weeks ago. The aim of this overall test was to verify the forces that occur with the simulation and to ensure that Compass can be recovered safely.
