Gas Generator ********** System for Europa Lander Stage Motor




Request for Information 

 



The ******** and Space ************** (NASA) invites to submit a response to this inquiry to assist NASA in assessing the Technology Readiness Level (TRL) and possible inclusion on the Europa Lander Stage Braking Motor of a gas generator driven system to separate it from the mission’s Powered Descent Vehicle (PDV).  response to this Request for Information (RFI) is sought within the context of the requirements and general approach described in the following sections and the associated appendix.  A detailed description of the Gas Generator ********** System (GGSS) and related system design requirements are contained in the attached Appendix.

Background

Proposed system, if utilized, would prevent impingement of hot exhaust gases and particulates onto the PDV.  Employment would also reduce time between Deorbtial Stage (DOS) braking motor detachment and ********** from the PDV.  Due to the nature of solid rocket motors operating in a space environment, a gas-generator driven system eliminates the low probability of braking motor re-contact with the PDV.  Gas generator units would be fabricated to actuate moveable struts and thus replace small, solid rocket motors used for ********** purposes on space missions.  Finally, the GGSS shall be able to meet a planetary protection requirement of a very low probability of a viable Earth organism contaminating another planet to an approximate probability on the order of 1x10-4 bio-reduction, and shall also be capable of surviving a high radiation d...
