The first testing of the HyImpulse hybrid rocket motor takes place

a test carried out at a German’s space organization DLR‘s Lampoldshausen facility saw launch startup, HyImpulse conduct a successful test on its 16,800pounds-force hybrid rockets this month. The company that is headquartered in Neustadt am Kocher, Germany, has been developing a three-stage SL1 launch vehicle that is designed to ferry consignments of up to 500 kilograms to Sun-synchronous orbit.

HyImpulse, a DLR spinoff, was established in 2018 and funded by German technology firm IABG, Rudolf Schwarz. The company has a 2.5 million euro grant that it receives from the European Commission. The purpose of the grant is for the company to make advancements in its launcher technology. The objective of the company is to be able to offer reliable and low-cost access to space frequently. 

The vehicle, which is a light-lift launch vehicle, will use 12 matching 16,800pounds-force fusion rocket engines. In its first phase, the car will use eight engines and four on its subsequent phase. Four other lesser versions of the engines will be used to power its final stage.

The hybrid rocket engine is driven by a combination of paraffin-based energy and oxygen. The engine is designed to utilize simple hardware compared to a liquid-fueled system while giving room for safety than motors that use solid fuel. 

By running its initial hot-fire experiment, it established that the paraffin/LOX hybrid rocket engine’s performance was the same quality as the liquefied hydrocarbon-based fuels. The agency utilized a more straightforward propulsion system than the liquid-fueled rocket engines enforcing reliability at a minimal cost. Apart from the hot-fire assessment being a crucial landmark on the corporation’s project to perform its first take-off of the SL1, the test also marked an essential step in the agency’s attempt to get ESA development funding. 

According to HyImpulse chief executive Mario Kobald, the company is expected to receive around 500,000 euros in Boost funding. The company, alongside Isar Aerospace and the OHB-backed Rocket Factory Augsburg, were chosen for the ESA program under Boost! That purpose of nurturing fresh viable space shipping amenities. The company’s funding will be used to complete the design of the SL1 and further stay operational as the company competes for a huge follow-on later.

The company will be looking to use a solitary 16,800-pounds-force hybrid rocket motor for powering a sounding rocket launched from the Esrange Space Center in Sweden in March.
