Prometheus is Europe’s initially extremely-reduced-charge reusable rocket motor demonstrator fuelled by liquid methane. It will advantage Europe’s new Ariane 6 launcher in the in the vicinity of-term and put together for a new era of European launch vehicles in the subsequent 10 years.

This is a 1000 kN course motor more improvement will shortly deliver this up to 1200 kN. It is highly versatile and reignitable, producing it ideal for use on core, booster and upper stages, reusable or not. It aims to slash expenses by an extreme style-to-expense technique, new propellant and innovative production technologies.

Additive layer-by-layer producing of Prometheus enables more quickly creation, with less pieces. Liquid oxygen–methane propellants are really efficient and greatly accessible and consequently a superior prospect for a reusable motor.

A entire-scale demonstrator will be fired in France at the conclusion of 2021 to de-possibility the Prometheus initially check campaign at the DLR German Aerospace Center in Lampoldshausen, Germany, anticipated in 2022. Prometheus will be utilized on Themis (a reusable very first phase demonstrator created in just FLPP) as aspect of an incremental inflight demonstration of reusability first in Kiruna, Sweden in 2023, and then in Kourou, French Giuana in 2025.

A Prometheus notion based on liquid hydrogen gas is also in enhancement to deliver an alternative to methane and could be offered for use on Ariane 6 as early as 2025.

ETID, an Expander-cycle Technological know-how Built-in Demonstrator, paves the way for the future technology of cryogenic higher stage engines in Europe in the 10-ton class.

Screening of a total-scale ETID demonstrator proved the most up-to-date propulsion systems. The check effects were being entirely analyzed including cross-checks to strengthen numerical designs as perfectly as the complete inspection of the examined hardware.

Synergy involving the Prometheus and ETID tasks has yielded activity-modifying additive production strategies for combustion chambers that lower charge and direct time.

Berta, a 5kN-thrust class, 3D-printed total-scale motor demonstrator for higher phases has executed tests at DLR Lampholdshausen. It makes use of ‘storable propellants,” named these types of because they can be stored as liquids at place temperature. Rocket engines that are powered this way are uncomplicated to ignite reliably and frequently on missions lasting a lot of months.

Continuing on from this venture and considering the environmental affect of the at the moment used storable propellants, investigations are ongoing to put together exams with identified new environmentally helpful propellant mixtures that remain storable but are much significantly less harmful.

Even more hybrid propulsion demonstrations are on-heading pursuing the start of the Nucleus sounding rocket in Norway, which efficiently achieved room by attaining a closing altitude of about 100km. View the complete videos listed here.

Supplies and procedures

Rocket higher phases are frequently produced of aluminium but switching to carbon composites lowers price tag and could yield two tonnes spare payload capacity. Credit rating: ArianeGroup

FLPP has been validating alternative supplies to make rockets lighter. New Composite products are remaining applied to replace aluminum for lighter upper phase buildings and fuel tanks, as effectively as for rocket fairings that shield the payloads on their way to place.

New insulation elements and jettison programs for rocket fairings will also offer a smoother quieter ride to room.

Closed-cell polyurethane foam material is getting sprayed on as exterior tank insulation for cryogenic upper stages and a new answer for tank bulkheads is presently staying created.

Secondary rocket structures could benefit from enhanced production processes these types of as artificial intelligence and device discovering, or advanced additive layer manufacturing for fracture crucial structural parts constructed in titanium, high toughness aluminum alloy and polymer.

Reusability

FLPP is also doing work on start car reusability with the initial methods to the in-flight demonstration of a prototype reusable rocket very first phase called Themis from 2023. The Themis undertaking will provide precious details on the financial benefit of reusability for Europe and verify a assortment of the systems matured in FLPP for possible use on foreseeable future European start motor vehicles.

A successful fall examination proved some of the technologies for a reusable very first phase of a microlauncher.

Wind tunnel screening and computational fluid dynamics are offering insights into European capabilities to management the descent of a rocket’s initial phase, back again to the floor.

In addition, an ongoing venture that includes a ‘flying testbed platform’ capable of carrying payloads has executed small take-off and landing examination flights.

Structures and mechanisms

Numerous new production methods are enhancing manufacturing performance, for occasion, a “Movement forming’ approach styles a metal aspect in a solitary step. This has been shown in production trials co-funded amongst ESA and NASA Langley.
