Upper Stage Test Stand P5.2

Flexible, adaptable and cost-efficient

The highly complex and extremely powerful P5.2 upper stage test stand is the latest test stand at DLR in Lampoldshausen and completes the portfolio of the DLR test site with its ability to qualify entire upper stages. The test stand was developed and built as part of the development of the future European launcher Ariane 6 on behalf of the European Space Agency ESA.

With the successful test on September 1, 2023 at DLR in Lampoldshausen, the newly designed upper stage of Ariane 6 has taken an important step towards qualification and first launch. With two ignitions of the Vinci engine and two ignitions of the APU, a highly complex requirement profile was mapped on the P5.2 test stand.

Areas of application

    • Low-pressure test bench for testing entire upper stages under ground conditions with the engine running
    • Fueling and defueling tests of cryogenic upper stages

Fuels

 

Liquid hydrogen

maximum 2.7 kilograms per second

Liquid oxygen

maximum 10.3 kilograms per second

Number of test positions

    • one test position

Current test object

The P5.2 test stand was specially designed and built by DLR to test the Upper Liquide Propulsion Module (ULPM) of the Ariane 6 upper stage. The upper stage consists of the Vinci engine, which can be ignited several times, the tanks for liquid hydrogen and liquid oxygen, pipes, valves and the electronic and hydraulic monitoring and control systems.
