HyImpulse Technologies (Neuenstadt am Kocher, Germany), in partnership with Greek advanced composite manufacturer Adamant Composites Ltd. (Platani-Patras), announce the successful completion of a hydrostatic burst test of a linerless carbon fiber-reinforced polymer (CFRP) liquid oxygen (LOX) tank. This marks a key milestone in the development of HyImpulse’s orbital Small Launcher, SL1.
According to HyImpulse’s website, SL1 will be a three-stage smallsat launch vehicle with hybrid rocket engines that will transport satellites with a payload of up to 500 kilograms into a dedicated Earth orbit. In addition to CFRP oxidizer tanks, the rocket will have a CFRP fairing — a component that protects satellites on the top of the launch vehicle.
The hydrostatic burst test is a critical step in the development of any pressure vessel and is used to ensure the safety and reliability of the tank under extreme conditions. The test subjects the tank to pressures far beyond what it is expected to experience in normal operation, to identify any potential weaknesses or failure points.
Adamant Composites reports that the linerless CFRP LOX tank passed the test with flying colors, demonstrating its ability to withstand pressures well beyond the limits of its intended use. HyImpulse and Adamant Composites declare this an important achievement, as the use of linerless CFRP tanks in space applications is relatively new in Europe and has not been extensively tested.
“The use of linerless CFRP in our LOX tanks significantly improves our performance and reduces weight and cost,” Mario Kobald, CEO of HyImpulse, says. “This successful test brings us one step closer to bringing this innovative technology to SL1 and revolutionizing the space launch industry.”
“We believe that revolutionizing access to space passes through revolutionizing composites structures design and manufacturing,” Antonios Vavouliotis, CEO of Adamant Composites, adds. “The unique full composites design provides 30% mass savings, while the robotic-inspired production process reduces the cycle time by 50% and cost by 25%.”
