ЦитатаESA to seek funding for more Prometheus reusable engines at ministerial
by Caleb Henry -- October 21, 2019

WASHINGTON -- The European Space Agency will ask its 22 member states next month to fund an additional two to eight Prometheus reusable engines so that the agency can further the engine's development.

ESA, with prime contractor ArianeGroup, has two Prometheus engines being built today, leveraging funds granted at its 2016 ministerial, plus earlier work supported by the French Space Agency CNES.

Jérôme Breteau, ESA's head of future space transportation, said Oct. 21 at the 70th International Astronautical Congress here that those two engines are on track for test firings in late 2020 at the German Space Agency DLR's Lampoldshausen facility. ESA will continue engine tests into 2021, but what follows "is the subject of our proposal to the Space19+ ministerial," he said.

ESA's tri-annual ministerial conferences are where the agency and its members allocate funds for future space programs. ESA is seeking 12.5 billion euros ($13.9 billion) at its next ministerial, dubbed Space19+, Nov. 27 -28 in Seville, Spain.

Breteau said ESA needs to know the outcome of the ministerial before it can lay out the next steps for Prometheus. The agency has "very ambitious" plans for the liquid-oxygen and methane engine, he said.

ESA's goal with Prometheus is to manufacture the engine for 1 million euros ($1.1 million) each -- a tenth the price of the Vulcain engine used on the first stage of Europe's Ariane 5 rocket. Prometheus is also designed to be reusable.

Breteau said Lampoldshausen's hydrogen engine test bench, used for Ariane 6's Vulcain 2.1 engine, will need upgrades to support the methane needed for Prometheus.

Breteau said Prometheus is so far in line with its cost target and its performance target of 1,000 kilonewtons in thrust. He said it is difficult to have a set mass target for Prometheus because that requires knowing what vehicle the engine will support.

Work on Prometheus has been done with the expectation that it would be used on a launch vehicle in the 2030s, but ArianeGroup has mused using it on the Ariane 6 rocket, which debuts in 2020.

Breteau wouldn't go so far as to name a launcher that might use Prometheus.

"System engineering on the target launcher configuration is ongoing," he said. ESA has what Breteau described as "more than a notional idea" of how to cluster Prometheus engines together on a launcher, a detail he said gives an "idea of the maturity of the system activities."

Цитата2. Prometheus engine spinoffs

The first Prometheus reusable engine is on track for completion by the end of 2020, with ground testing to follow. ArianeGroup is preparing the engine for use in the 2030s, but Bonguet said the company can start applying Prometheus technology to Ariane 6's expendable Vulcain 2.1 first-stage engines and Vinci second-stage engines. Prometheus, in addition to being reusable, leverages extensive 3D printing with the goal of costing 1 million euros to manufacture (a tenth the cost of Ariane 5's Vulcain engine). Bonguet said spinoff technologies like electrical valves and 3D-printed parts from Prometheus could reduce the cost of Ariane 6's expendable engines.

Цитатаhttps://frog.cnes.fr/fr

FROG est un acronyme récursif qui veut dire « FROG, a Rocket for GNC demonstration ». Initié par la Direction des Lanceurs du CNES pour tester des algorithmes d'atterrissage de lanceurs réutilisables, FROG est un démonstrateur à petit échelle de concepts VTVL (Vertical Take-off, Vertical Landing, Décollage vertical, atterrissage vertical). Avec ses 3 mètres de haut et 30 centimètres de diamètre, son rôle est celui d'un véhicule d'apprentissage.

 Скрытый текст:
Les équipes de la Direction des Lanceurs, avec les partenaires industriels, universitaires et associatifs, y greffent de nouveaux algorithmes de guidage, navigation et contrôle du vol (GNC), de pilotage de poussée avec l'objectif de tester de façon réactive et avec des temps de développements courts, de nouvelles solutions. Ces idées une fois validées pourront être intégrées dans des architectures plus importantes comme les démonstrateurs réutilisables Callisto, Themis et d'autres projets qui verront le jour dans la prochaine décennie.

FROG est aussi une initiative qui tente de sortir des schémas de développement traditionnels, en valorisant les interventions extérieures à la Direction des Lanceurs. Plusieurs équipes de passionnés développent et testent leurs solutions en parallèle dans une approche agile et expérimentale. Pour faire émerger rapidement de nouvelles méthodes de pilotage, sans se mettre de frein technologique

Le premier vol du prototype FROG, propulsé pour l'instant par un turboréacteur, a eu lieu fin mai 2019. Le véhicule est équipé de tout le nécessaire pour se poser à la verticale : une tuyère orientable, un contrôle actif de l'attitude et quatre pieds qui amortissent l'atterrissage. Dans un avenir proche, il est envisagé de remplacer le turboréacteur par un petit moteur fusée pour que les tests soient encore plus fidèles.

 Скрытый текст:
Les deux démonstrations en vol captif de décollage et d'atterrissage ont été un succès. FROG est un démonstrateur de vol à échelle réduite qui a pour but de tester des algorithmes d'atterrissage vertical au profit des futurs lanceurs réutilisables.

L'équipe projet prépare actuellement la Revue d'Aptitude au Vol libre (RAV) qui se déroulera courant octobre et autorisera les essais en vol libres, sans portique ni câble de sécurité.

FROG est une plateforme d'expérimentation à faible coût de l'ensemble de la chaîne de contrôle de vol (guidage, navigation, pilotage, régulation de poussée, etc). L'objectif est de tester divers approches et algorithmes de la Direction des Lanceurs mais aussi ceux issus de projets étudiants.

Le projet FROG a vu le jour il y a deux ans, et après une première année d'étude de concepts, deux concepts et une logique de développement ont été sélectionnés.

La particularité de FROG c'est son équipe de développement qui s'appuie sur une organisation collaborative et agile ainsi que sur une approche expérimentale. Cette équipe est constituée du CNES, dont le rôle va au-delà de la maîtrise d'œuvre habituelle, de Planète Sciences, de Polyvionics, de l'IUT de Cachan, Drone Center et Sonatronic.

L'organisation atypique de FROG regroupe des bénévoles provenant d'industriels du spatial et de l'aéronautique, des ingénieurs, des enseignants, des étudiants et divers experts dont une équipe pluridisciplinaire de la Direction des Lanceurs du CNES.

Planète Sciences est une association scientifique de portée nationale sur les thèmes de l'espace, de la robotique, de l'astronomie et de l'environnement. Son département Espace réalise des activités expérimentales de fusées, ballons, drones, cansat, propulsions et campagnes de lancement.
Polyvionics est une Jeune Entreprise Innovante (JEI) de R&D dans le domaine de l'aérospatial et des drones, spécialisée dans les systèmes de guidage automatique et d'avionique.
L'IUT de Cachan intervient dans le projet par l'intermédiaire de son fablab et incubateur, l'Innovlab, qui réunit les moyens techniques de l'IUT, les enseignants et des étudiants.
Drones-Center est une PME qui développe et opère des drones sur la Base Aérienne 2017 de Brétigny-sur-Orge.

ESA to seek funding for more Prometheus reusable engines at ministerialby Caleb Henry -- October 21, 2019
1. ЕКА попросит  в следующем месяце финансировать увеличение (с двух до восьми) количества многоразовых двигателей Prometheus, чтобы агентство могло продолжить отработку двигателя.

2.Два двигателя находятся на пути к испытательным прожигам в конце 2020 года на объекте Lampoldshausen немецкого космического агентства DLR.

3. ЕКА  имеет "очень амбициозные " планы в отношении  метанового двигателя.

4.Целью ESA с Prometheus является производство многоразового двигателя за 1 миллион евро (1,1 миллиона долларов) каждый - десятая часть цены двигателя Vulcain, используемого на первой ступени европейской ракеты Ariane 5. 

5. Разработка идёт  в соответствии с его плановыми затратами и целевому показателю тяги в 1000 КН .
Чтобы выяснить требуемое количество  Прометеев, нужно знать, какие носители будут его использовать.

6.Работа над Prometheus была начата с расчетом, что он будет использоваться на ракете-носителе в 2030-х годах, но ArianeGroup задумалась об использовании его на ракете Ariane 6, которая дебютирует в 2020 году.

7.Идет проектирование установки сразу нескольких  двигателей Prometheus на РН,
и это  дает" представление о степени продвинутости хода разработки."

А по поводу повторного использования?

Все зависит от объемов производства. В случае с Space X мы видим, что Элону Маску нужен объем, чтобы сделать его ракету прибыльной. Не случайно, что с его проектом созвездия Starlink, в котором 42 000 спутников [предназначено для телекоммуникаций, чтобы охватить всю планету] , он стал своим собственным клиентом! Мы сказали, что будем готовы пойти на повторное использование, если рынок, институциональный и коммерческий объем оправдают это. В этом плане мы надеемся, что министерская конференция профинансирует недорогой двигатель с переменным тягом под названием Prometheus, а также Themis, демонстратор повторного использования.

Цитата: undefinedESA moves ahead on low-cost reusable rocket engine

ESA's Prometheus is the precursor of ultra-low-cost rocket propulsion that is flexible enough to fit a fleet of new launch vehicles for any mission and will be potentially reusable.
At the Space19+ Council meeting in Seville, Spain last November, ESA received full funding to bring the current Prometheus engine design to a technical maturity suitable for industry. Developed by ArianeGroup, Prometheus is now seen as key in the effort to prepare competitive future European access to space.
By applying a design-to-cost approach to manufacturing Prometheus, ESA aims to lower the cost of production by a factor of ten of the current main stage Ariane 5 Vulcain 2 engine.
Example Prometheus flight configuration

Features such as variable thrust, multiple ignitions, suitability for main and upper stage application, and minimised ground operations before and after flight also make Prometheus a highly flexible engine.
This Prometheus precursor runs on liquid oxygen-methane which brings high efficiency, allows standardisation and operational simplicity. Methane propellant is also widely available and easy to handle.
In the short term it is likely that operational engines will benefit from the application of Prometheus technologies.
P5 testing facility at DLR Lampoldshausen P5 testing facility at DLR Lampoldshausen

Upcoming tests overseen by ArianeGroup at the DLR German Aerospace Center's Lampoldshausen testing facility in Germany will validate the hardware components for the first Prometheus engine test model (M1).
In preparation, the P5 test bench will gain a 250 cubic metre capacity propellant tank for methane. This will allow engineers to efficiently switch test configurations between Prometheus and Ariane 6's Vulcain 2.1 main stage engine, also in development.
Main subsystems are being manufactured. The first elements built last year benefited from new methods such as additive layer manufacturing (ALM) which speeds up production, achieves fewer parts and greatly reduces costs.

ALM builds a structure layer by layer, which is much quicker and easier than the traditional process of cutting away bulk material. Complex, optimised parts, impossible to manufacture via classical methods, can be created using less material and energy, and in far fewer manufacturing steps.
Components manufactured and now ready to test include the turbo pump's turbine, pump inlet and gas generator valves. March will see the delivery of the chamber valves and on-board rocket engine computer for engine management and monitoring - the part that makes this a 'smart' engine and potentially reusable.
Prometheus Prometheus
The first combustion chamber model is expected at the end of June while the combustion chamber for M1 will be delivered in December 2020.
Engineers will assemble the M1 full-scale demonstrator at the end of this year for testing on the ground in 2021.
Further Prometheus engines will be built for testing into the future.
Also within ESA's Future Launchers Preparatory Programme, Arianeworks is currently preparing an in-flight reusable vehicle demonstration called Themis, which will incorporate the Prometheus precursor engine.
Prometheus represents a breakthrough in terms of cost and manufacturing and its robust design is the baseline for future evolutions of Ariane to 2030.

 ArianeWorks, the innovation accelerator created by CNES and ArianeGroup, keeps up the momentum
07-17-2020 |  5 minutes

Creativity, collaboration and quickness for making projects a reality
Established in February 2019 to accelerate the development of future European launchers and in particular the reusable stage demonstrator Themis, ArianeWorks is embarking on a new phase in the realization of its projects.
Less than a year after its creation, ArianeWorks provided persuasive proof of the viability of the Themis project at the European Space Agency (ESA) Ministerial Council in 2019, and has just been authorised to continue the work pending finalization of an initial development contract.
This support from ESA means that ArianeWorks is now in a position to escalate the development of Themis and is preparing for the first tests with the Prometheus new-generation engine demonstrator in 2021.



For the first tests, the team has set up at the ArianeGroup site in Vernon (northern France), where it will be working on various tank configurations and operations. The first prototypes have recently been installed in the historic "PF20" test area.
The Themis demonstrator will not only validate ultra-low-cost solutions, but will also contribute to energy transition in the launcher industry, making it highly eco-responsible through the use of biosourced fuel, recoverable infrastructure, clean transport etc.
In these 18 months, which have been full of innovation, the initiative launched by CNES and ArianeGroup has been extended to five manufacturing partners, all of whom have been contributing ideas, innovations and know-how for Themis (and ArianeWorks is getting ready to welcome more this summer):


A number of experiments over this period have helped to accelerate ideas for Themis, often by involving highly dynamic entities (SMEs or start-ups) from outside the space sector: wireless avionics, low-cost thermal protection, use of robots in operations, and more.

These ideas have now been incorporated into the larger-scale test programme which ArianeWorks is about to commence on behalf of ESA.

ArianeWorks moving forward for next generation European rockets

Summer'20 update on ArianeWorks, the innovation platform initiated by ARIANEGROUP and CNES to boost the Ariane rocket roadmap.
In spite of the Covid crisis, ArianeWorks has been transiting in the last few weeks from a so called "pilot phase" to a more intense stage, enabled by the pre-award of an European Space Agency contract for THEMIS, a demonstration for a low cost and reusable rocket stage that shall pave the way for the 2030 European space fleet. Better than lenghty explanations, you can get a look at the notional plan herebelow and pay of visit at ArianeGroup latest post to figure out ambitions for this project, which is building upon CALLISTO experimental vehicle and PROMETHEUS new European rocket engine.
Aucun texte alternatif pour cette image
The successful transition for ArianeWorks from the "pilot phase" is a result of a number of achievements completed during the past 18 months : swiftly pre-engineering of the THEMIS rocket vehicle, work on tech ideas for future Ariane concepts, and set up of a volontarist experimental approach. This last part - experiments - is the easiest to illustrate, with pictures of hardware popping up here and there on the historic (Ariane 1!) PF20 zone in ArianeGroup Vernon. Subscaled or scale 1 tanks showed here are meant for test & learn of operations, interfaces, tanking...etc. Though of course not yet flight hardware, they include some of the features targeted for THEMIS, such as common bulhead or internal feed lines.

These achievements are also enabled by the involvement of several industrial partners who joined the collaborative ArianeWorks platform, bringing together background, skills and inspirations for incubating next generation of European rockets. Current partners include ONERA, SABCA, APCO, ADF, RUAG, and the community will likely soon expand for tackling the challenges of Ariane NEXT (or Ariane 7, as Thierry Breton named it).    
Last but not least, herebelow a glimpse on a often overlooked aspect of THEMIS, although it stands high on our agenda : eco-conception. Ariane 2030 vision do include both an economic and an ecological responsibility ambition. And THEMIS is meant to serve as pathfinder on both fronts. Manufacturing, energy, transport, facilities...herebelow an overview of some of the actions / strategical options considered, supported by Life Cycle Analysis to weight options and help steer upcoming design choices. Zoom in and get a closer view !

Cannot conclude without highlighting that next generation of rockets desserve next generation of rocketeers ! We feel very grateful for trainees, apprentices, OpenSpaceMakers amateurs or student teams from the Perseus program that are bringing fresh ideas and passion to these projects. We need you, so stay tuned for upcoming opportunities.
