In una nota la NASA cambia i documenti dell’appalto in corso e richiede alla Rocketdyne di sviluppare per il CEV dei motori a razzo spendibili, derivati dall’RS-25, ma di costo minore di quanto preventivato nella precedente documentazione risalente allo scorso febbraio.
NASA/MSFC has baselined the use of a lower cost version of the Space Shuttle Main Engine as the Core Stage Engine (CSE) for the proposed Cargo Launch Vehicle (CaLV). At this time, special studies are needed to evaluate and assess the processes and requirements necessary to develop and certify the CSE for the CaLV. The Core Stage Engine will be a highly affordable, expendable engine derived from the current Space Shuttle Main Engine (RS-25).
Pursuant to FAR 6.302-1, NASA/MSFC intends to purchase the special studies effort from Pratt & Whitney Rocketdyne (PWR), Inc., 6633 Canoga Avenue, Canoga Park, California, 91309-7922. The Rocketdyne organization, now a division of PWR, has designed and developed the RS-25 engine and has been responsible for its production, refurbishment, and improvements since 1972. Consequently, PWR is the only company that has the requisite expertise to perform these special studies, which are a follow-on to the development work they have been doing on the RS-25 engine.
