[ARTEMIS Program USA] Human Landing Système du team Dynetics

[montmein69_2]

Ce HLS est l'un des trois projets retenus par la NASA pour l'atterrissage sur la Lune.

Dynetics vient d'annoncer une liste de tests réalisés sur différents systèmes qui sont en développement et doivent équiper l'atterrisseur. Il s'agit de répondre aux demandes de la NASA qui doivent conduire à l'agrément concernant la construction.

Dynetics, a wholly owned subsidiary of Leidos, has submitted its proposal for Option A of the Human Landing System (HLS) for NASA's Artemis Program. The Dynetics team has also completed the HLS Continuation Review, a critical milestone during the 10-month base period, which NASA will use to assess progress on HLS hardware development and program plans.

At the Continuation Review, Dynetics provided details to NASA on its early design efforts, mission plans, and its hardware and software build as well as test activities that demonstrate tangible, robust advancement towards NASA's mission objectives.

 

 

Dynetics déclare avoir fourni à la NASA des résultats sur le matériel et sur la partie logicielle ainsi que leurs tests, attestant d'une sérieuse avancée pour remplir les objectifs qui lui ont été fixés par la NASA

 

Le design du HLS (lorsqu'il sera construit) devrait ressembler à cela

 

Dynetics travaille avec plusieurs partenaires experts dans leur domaine

Dynetics leads a global team of industry-recognized experts with human spaceflight and hardware/software experience directly applicable to the HLS. All members have made significant contributions to the team's progress to date.

Sierra Nevada Corporation (SNC) led the completion of a medium-fidelity hardware test article, which is located at NASA's Johnson Space Center (JSC) in Houston, Texas. Like its low-fidelity siblings, this test article will be used by NASA astronauts and operators to improve the Dynetics crew module design. Among many other early demonstrations, SNC has created a virtual reality simulator to evaluate how future crews would view the lunar surface and landing site on approach.

Houston-based Oceaneering has provided design and development of crew system intra-vehicular and extra-vehicular activities (IVA/EVA) and crew training plans. Oceaneering recently supported successful completion of the preliminary design reviews for crew operations and crew systems held in October and December, respectively. The company has also completed dust mitigation technology demonstrations, using its Debris Vacuum Assembly (DeVA) hardware. Additional dust mitigation technology demonstrations are ongoing at NASA's Kennedy Space Center (KSC).

Paragon Space Development Corporation has reached the Environmental Control Life Support System (ECLSS) preliminary design review within seven months of program kickoff. Key ECLSS component tests were conducted at NASA's Glenn Research Center (GRC). The maturity of Paragon's ECLSS technologies will lead to a faster transition from the critical design review and flight hardware delivery.

Maxar Technologies completed preliminary designs for many of the Dynetics Human Landing System's major subsystems, including its power, avionics and communications and active thermal control subsystems. These preliminary designs and plans will be reviewed by the Dynetics and NASA teams during Subsystem Preliminary Design Reviews in early January 2021.

The Dynetics lander team has also performed detailed analyses on a wide range of mission-specific phenomena, such as the interaction of main engine exhaust plumes with the lunar regolith and computational fluid dynamics (CFD), analysis of cabin airflow to improve the design, and placement of the air revitalization system.

Suite à la désignation d'un seul des protagonistes comme "lauréat" du premier contrat de HLS (à savoir Space X devant percevoir les 2,9 G$ pour son Moon Starship), et la contestation officielle des deux"recalés" soit Dynetics et le National team-Blue Origin, cela semble pouvoir évoluer.

Le Sénat a demandé à la NASA de désigner un second "lauréat" dans les 30 jours suivant son décret. Il y aura une petite rallonge pour le financement portant le total à un peu plus de 10 G$ (il n'est pas clair si Space X conserve son montant initial ou s'il y a une nouvelle répartition)

Citation

The amendment directs NASA to fund development of “not fewer than 2 entities” in the HLS program no later than 30 days after the bill is enacted. It would authorize a total of $10.032 billion for the program, although funding would have to be appropriated separately, and on an annual basis.

Affaire à suivre 😜

Dynetics était semble-t-il arrivé en second dans la phase initiale de choix. Sera-t-il le bénéficiaire de cette opération de repêchage ?

 

A noter : le montant de 10 G$ et la formulation "not fewer than 2 entities" laisse possible la qualification et le financement des trois candidats.
