Lampoldshausen Testing Facilities Workshop
The DLR-Institute of Space Propulsion has unique expertise in Europe in the development and operation of test facilities for liquid rocket engines. Within the European space program engines for launchers and space propulsion systems have been tested and further developed at the site in Lampoldshausen since 1959. The workshop gives a comprehensive overview of the most important test stands at Lampoldshausen.
P5 – Test Bench for Ariane Main Engine – Prepared for the Future
Dr. Philipp Altenhöfer
The ESA test bench P5 was developed and built in frame of Ariane 5 development. From 1990 on numerous development and qualification tests were performed on Vulcain, Vulcain 2 and Vulcain 2.1 engines under sea level condition. At the moment the test bench is under modification for testing the new LOX-methane engine precursor Prometheus.P5.2: European Versatile Stage Test Facility
Gerhard Krühsel
The P5.2 test bench at DLR in Lampoldshausen has been built as a versatile test platform for testing H2/O2 stage tank system.First test specimen is the hot firing module (HFM) representing a complete Ariane 6 upperstage.The hot firing of the HFM stage is performed under ambient conditions with altitude simulation at some stage bench I/F.Basic test bench subcomponents will be presented and an overview of the complete test bench system will be given.Some major technical project milestones will be reflected with regard to decision making justification and realization.IF the first hot run has been realiszed up to the FAR conference (first test foreseen in May22) some first bench results will be presented.
Operation of Test Facilities for Upper Stage Engines: High Altitude Test Facility P4
Christopher Gusinde
Engines that are installed in rocket upper stages, satellites or space probes operate at high altitudes above ground (vacuum) which affects the ignition of the engines.In vacuum there is no convection and engines develop more thrust and are thus exposed to greater stresses and strains.To simulate these conditions, vacuum test facilities like P4 are needed which are capable of creating vacuum during the hot firing test of an engine.
During the test an analysis and measurement of ignition behavior, thermal stress of the structures, vacuum thrust etc. are performed continuously.
The German Aerospace Center at Lampoldshausen operates a variety of vacuum test facilities. The biggest one is P4:
P4.1: VINCI engine (cryogenic propellants, 180 kN)
P4.2: AESTUS engine (storable propellants, 27.5 kN)
The Test facility P2 as a High Flexible Test Plant for Current and Future Engines
Volker Kraft
The P2 is originally designed to test Rocket Engines up to 1MN. The P2 was constructed during the years 1962-1963. Due to the high flexibility of the facility many different engines were tested at this facility during the past. The highest generated thrust was 0,3 MN. The P2 is now used to test development engines for the new Kick Stage of the Ariane 6 (BERTA: Biergoler Space Transport Drive). The presentation treats the test configurations and the operation of the P2 facility. Future projects will also be presented.
Research and Technology Test Bench P8 and P8.3
Lino Müller
The P8 test bench has been operating since 1995 for research and technology development activities on cryogenic rocket propulsion systems. It comprises supply systems for all media necessary within two high pressure test cells.In 2021, the testing and research capacities of P8 have been extended by a third test cell (P8.3) which has been integrated into the existing media infrastructure.
This low-pressure design allows testing of complete pump-fed engines with cryogenic propellants as well as single component testing (e.g. turbo pumps).
Overview on the DLR M3 Test Infrastructure
Dr. Michael Börner
The speech will give an overview on the DLR M3 test infrastructure and its capabilities to perform tests for space propulsion research.
Green and Advanced Storable Rocket and High-speed Airbreathing Propulsion – Highlights and Capabilities of Test Complex M11
Dr. Christoph Kirchberger
The Satellite and Orbital Propulsion Department of the DLR-Institute of Space Propulsion in close cooperation with the Chemical Propellant Technology Department carries out research on the applicability, compatibility and handling of both known and new propellants and energetic materials for green and advanced storable rocket and high-speed airbreathing propulsion. For this purpose, the department operates at the DLR site Lampoldshausen the M11 Test Complex which unique test positions enable development, characterization and testing of new propulsion systems up to a TRL of 3 to 5. The talk provides an overview on the capabilities of M11 and presents specific highlights of the research currently conducted.Green Hydrogen at DLR Lampoldshausen – Extension of the Existing H2 Infrastructure
Andreas Haberzettl
At DLR Lampoldshausen an extensive media supply infrastructure for the test facilities is used since decades. In the framework of the ongoing projects H2orizon and Zero Emission green hydrogen is produced using wind power. The integration of the new systems into the existing hydrogen infrastructure provides more flexibility without reducing the current performance characteristics. The talk presents the development of the new systems, and the extension of the existing hydrogen infrastructure.
