High-Pressure Combustor Test Facility 5
The test facility is a validation tool for researching and testing CO2-free combustor technologies to accelerate the transformation of the energy system and air transport.
Due to its dimensions, the High Pressure Combustor Test Facility 5 (HBK 5) offers the possibility to validate combustion chamber component technology up to a thermal output of 125 megawatts. As part of DLR's research collaboration, experiments are carried out with industrial partners to simulate real-cycle process parameters for pressure and temperature. The design of the test facility allows synergy effects in the experimental development of flying and stationary CO2-free gas turbines. This includes full-ring combustors and single combustors from engine design. Component testing provides the developer with added technological value to vary inlet conditions and air and fuel mass flows with a high degree of flexibility, independent of the overall system.
Full-scale testing with original combustors in a component test, unrestricted by compressor and turbine operating windows, is an accelerator in the development process. The existing infrastructure for the use of future fuels such as hydrogen and Sustainable Aviation Fuels (SAF) increases the speed of innovation from technology development to market maturity. The globally unique HBK5 research platform accelerates the time-critical transformation of the energy system and aviation towards CO2 freedom.
