Main stage engine for Ariane 6 on the test stand at DLR Lampoldshausen

First ignition for Europe's most powerful rocket engine, the Vulcain 2.1
 
23 January 2018

The new Vulcain 2.1 engine, featuring a 3D-printed gas generator, a redesigned, simplified nozzle and a combustion chamber that can be ignited by the launcher's ground support system will bring the future Ariane 6 launcher to space.

•For the first time, the new Vulcain 2.1 engine was tested for use with the future Ariane 6 European launcher.
•DLR carried out the test in the P5 test rig at the site in Lampoldshausen on behalf of ArianeGroup.
•Focus: Space, space propulsion

The new Vulcain 2.1 engine, which is set to carry the new European launcher Ariane 6 into space in 2020, is intended to achieve greater efficiency at lower costs. However, before such a launch can be successfully carried out, the development engines must prove that they can cope with the enormous 130-ton thrust, temperatures of approximately 3000 degrees Celsius in the combustion chamber, the high rotational speeds of the turbo pumps and the pressure in the propellant lines. On 22 January 2018, engineers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) carried out a first successful test of the engine, developed by the ArianeGroup, on test stand P5 at Lampoldshausen. "We can evaluate the functional capability of the engine for the main stage only by constantly carrying out tests, in which we gradually take steps towards its ultimate use in space," explains Stefan Schlechtriem, Director of the DLR Institute of Space Propulsion. A total of 12 firings are planned for the first test campaign at DLR.

Its predecessor, the Vulcain 2 main stage engine, is currently used on the Ariane 5 launcher and has so far completed 70 successful flights in a row. To create a more cost-effective and efficient generation of engines, Vulcain 2 is being redeveloped into the new Vulcain 2.1 engine, featuring a 3D-printed gas generator, a redesigned, simplified nozzle and a combustion chamber that can be ignited by the launcher's ground support system. Vulcain 2.1 will play a key role in carrying Ariane 6 up to an altitude of 150 kilometres within the first 10 minutes of flight. The DLR test on the Vulcain 2.1 main stage engine lasted 11 minutes, roughly a third longer than the engine would need to carry the Ariane 6 launcher up into space, assisted by solid-propellant boosters.

Step-by-step progress towards the launcher of the future

The decision to develop a new launcher system was taken in December 2014, when the member states of the European Space Agency (ESA) held their Council Meeting at Ministerial Level. They decided to opt for an enhancement of the existing generation of Ariane launchers in order to adapt to growing competition and heightened expectations on the world market. The new launcher was to build upon the existing components of Ariane 5. Depending on the configuration, Ariane 6 will be able to transport a payload of up to 11 tons into space, halving the cost of launches compared to Ariane 5. The new re-ignitable Vinci engine for the upper stage of Ariane 6 has been one of the elements tested at the DLR site in Lampoldshausen since 2005, and now the test runs for the new Vulcain 2.1 main stage engine have been added to the site's portfolio.

Modern test stands for safe and reliable engines

The aim of the seven-month test campaign is to gain a thorough understanding of all key features that distinguish the new main stage engine for the Ariane 6 launcher. "Only those who are fully familiar with these features can adjust the delicate combination of mechanical and electronic components, and thus get the engine to a stage where it is technically mature," stresses Schlechtriem. The first test was based on the Vulcain 2 engine, which has already been developed and is used in the current Ariane model. In this case, all of the pyrotechnical igniters were retained in order to compare the new engine with the older version. For the next test run, the combustion chamber will be ignited from the test stand using propane gas. At the end of the test campaign, the engine will have to successfully complete a final rehearsal on the DLR test stand in its definitive flight configuration.

"Testing is not just about seeing how this technology fares under normal operating conditions. We want to look at how it copes with stresses that go beyond those normally experienced in flight – in other words, at higher temperatures, at high and low combustion chamber pressures and with different fuel mixture ratios," says Anja Frank, Head of the Department of Test Facilities at DLR Lampoldshausen. "We are using the development engine to assess the limits of the Vulcain 2.1."

Data for a reliable engine

The results of the tests carried out by engineers, technicians and test stand workers at the DLR Institute of Space Propulsion will not only be proof of the engine’s functional capabilities, but also a source of a large amount of data. Ultimately, the use of a high-precision measuring and analysis system makes it possible to obtain accurate results and thus allows the ArianeGroup engine developers to draw detailed conclusions about technical issues. The final design of the main stage engine requires a thorough understanding of the pressures and temperatures in the propellant lines, the rotational speeds of the turbo pumps, the pressures in the gas generator and combustion chamber, and the resulting vibrations to which the engine is subjected during a hot run.

Successful first test of the Ariane 6 Vulcain 2.1 engine

European Space Agency, ESA
Published on Jan 24, 2018

The first hot firing of Ariane 6’s Vulcain 2.1 main engine was performed in January 2018 at the DLR German Aerospace Center test facility in Lampoldshausen, Germany.

The engine, developed by ArianeGroup, has a simplified and more robust nozzle, a gas generator made through additive manufacturing, and an oxygen heater for oxygen tank pressurization. These features lower the cost of the engine and simplify manufacturing.

Second Ariane 6 and Vega-C solid rocket motor prepared for testing

2 February 2018

Two models of the common solid rocket motor for Ariane 6 and Vega-C are being prepared and tested at Europe’s Spaceport in French Guiana.

The first full-scale model of the P120C was cast while vertical with 142 tonnes of inert propellant in October. This was left to stabilise, cool and harden – the curing process. The motor was rotated for horizontal integration.

The igniter and nozzle are attached first, the remaining parts will complete the motor.

In two weeks, the inert model will be moved to the test stand. Although it cannot be fired, the procedures and connections will be proved in readiness for the firing of the development model later this year.

Ten kilometres from the stand, the development model is curing with active propellant in the Guiana Propellant Plant.

The P120C is the largest solid-propellant motor ever built in one segment, at almost 11.5 m long and about 3.4 m in diameter. Two or four will be strapped to Ariane 6 as boosters for liftoff. Two boosters will be used on its maiden flight in 2020.

Vega-C is expected to debut in mid-2019 with P120C as the first-stage motor, which will increase performance from Vega’s current 1.5 t to about 2.2 t in a reference 700 km polar orbit.

AFAIK three P120C stages will be bench tested on the BEAP to qualify the P120C for Vega-C and Ariane 6.
Nice how they are already using the new assembly proces before the dedicated facility is finished.
(I know Update topic, I think this is relevant info)

For correctnes lets also add the ESA article Ariane6 launch site visit

Ariane 6 launch table takes shape in Kourou
Quote
The table that will support Ariane 6 on the pad is being assembled at Europe’s Spaceport in French Guiana.

This 700 tonne steel structure is 4 m high, 20 m long and 18 m wide and sits in the centre of the launch pad. It is so large it had to be dismantled before it was shipped from Germany.
 
The table arrived in Kourou on 30 January and was moved by truck to a preparation area about 200 m south of the Ariane 6 launch pad.

Now that the main structures of the table are in position, engineers have begun welding them together and will be finished by the end of April.

The installation of equipment inside the table such as the fluid and cryogenic systems, power supply, air-conditioning and security systems will follow in early May.

In August the table will be transferred to the pad for final installation.

The table and all ground systems will be validated and checked by the end of September 2019.

At liftoff, the table is subjected to very high pressures and temperatures from the booster plumes.
 
Machinery installed inside the launch table must also withstand strong vibrations and the acoustic environment generated at liftoff.

Ariane 6’s maiden flight is planned for mid-2020.
