- Description
- Attachment 2 - Figures Attachment 1 - Nominal Specifications for the CRS Space Qualified Linear Actuator National Aeronautics and Space Administration (NASA) Langley Research Center (LaRC) is issuing Request for Information (RFI) to request industry input on the availability and capability of 100 VDC linear drive actuators to support the Contact and Restraint Subsystem of the Asteroid Redirect Robotic Mission (ARRM). The ARRM Asteroid Redirect Vehicle (ARV) as planned will consist of spacecraft (Mission Module and Solar Electric Propulsion Module) and a Capture Module. NASA is providing the design and development of the Contact and Restraint Subsystem (CRS) as part of the Capture Module design and development. For ARRM, the CRS has three primary functions: 1) halt the motion of the spacecraft upon touch-down on the asteroid surface; 2) provide the force required to depart from its surface with an acquired boulder; and 3) restrain the boulder after asteroid departure with appropriate restraint force. The CRS consists of a three (3) leg space-frame structural design, with each leg divided into four individually linear actuated segments with each leg offering a range of controllable motion to accomplish these three functions for an identified range of collectable boulder sizes (see Attachment 2, Figures 1 and 2). NASA is anticipating that twelve (12) linear actuators will be implemented in the CRS flight hardware configuration (4 actuators per leg). Results from recent concept architecture assessments and analyses indicate a need for a three-phase brushless 100 VDC gear motor and a ballscrew/ballnut set of a common design at all twelve (12) CRS actuator locations, with the need for the linear actuator to provide the three following driving mechanical characteristics: 1) stroke length of twenty-four (24) inches; 2) variable stroke rate between 0 in/sec to 2.0 in/sec; and 3) dynamic force capability of 1000 lbf. Before flight, each actuator will go through rigorous testing that consists of ambient and environmental performance tests including loads testing, vibration, and thermal vacuum testing. For the ARRM mission and the CRS need, these actuators are required to be of the proper construction, parts quality, and capable as required for space flight operation and non-operation survivability in-line with deep space mission environments and temperature ranges. NASA is also anticipating that 12 linear actuators will be implemented in a CRS Engineering Development Unit (EDU) that is to be fabricated prior to the flight CRS build. The CRS EDU will be a form, fit, and function version of the flight design. The selection of materials and processes used to construct the EDU shall match that of the flight design; however, for the EDU, the pedigree of some of the parts and materials used in the construction of the EDU may be relaxed provided reasonable justification is provided without any sacrifice in functional performance or safety of the delivered hardware. NASA anticipates that this would be the approach allowed for the anticipated need of the EDU designated linear actuators. Additional nominal specification and requirements are contained in Attachment 1, Nominal Specifications for the CRS Space Qualified Linear Actuator. NASA encourages each respondent to thoroughly review Attachment 1 prior to responding to the RFI. RFI Submittals: Interested parties should respond with the following information: 1. General Description a. Describe the company's capability to meet the specifications and requirements Attachment 1; specifically noting any areas of noncompliance and recommendations to mitigate or correct the noncompliance; including changes to the requirements themselves. 2. Flight or Technology Heritage/Qualification a. Describe the company's relevant experience with manufacturing linear actuators; especially experience with space flight qualified hardware as described above. b. Describe the extent to which existing proven commercial technology can be leveraged to minimize technical and schedule risk. c. Describe any new technologies to be employed on this effort, and any modifications to existing technology, necessary to meet the requirements. Describe risks associated with incorporating the new or modified technology and how the risks can be minimized. 3. Test and Inspection Program a. What test program(s) or evidence could be offered to demonstrate that the linear actuator will meet the specifications and requirements provided in Attachment 1? b. Submit a sample of existing manufacturing, inspection and test, and acceptance plans to control this type of work, and list any current International Standards Organization (ISO) certifications or equivalent. c. Describe whether the linear actuator that NASA is seeking information on has been, in whole or in part, qualified for space flight and if so, describe the qualification program including environments used (e.g., against a MIL spec. or other). 4. Linear Actuator Mechanical Mount approach a. Submit or provide a description of the various mounting schemes offered for the linear actuator. 5. Costs a. If the actuator has undergone a flight qualification for a similar application (or has the capability to undergo one as it is currently designed), please provide Rough Order of Magnitude (ROM) costs to deliver sixteen (16) EDU units and sixteen (16) flight units. b. If the actuator is commercially available, please provide an "Off-the-Shelf" procurement estimate for sixteen (16) EDU units and sixteen (16) flight units c. If the responder must make modifications to an existing design in whole or in part, please provide a ROM for the non-recurring engineering for the necessary modifications needed. d. If the responder must incorporate new technologies or make modifications to existing technologies, please provide a ROM for any development plans and associated costs. 6. Delivery a. Provide an estimated delivery timeframe. b. Address major risks to meeting the delivery and how can they be overcome. 7. Procurement Strategy a. NASA is researching whether to issue this requirement as commercial solicitation under the authority of FAR part 12 and Simplified Acquisition Procedures set forth in FAR Part 13. Indicate whether this solicitation type is appropriate. Limit your responses to 8 pages or less not including diagrams, pictures, or figures. Existing documents that describe suitable existing products or proposed products are acceptable as attachments to your response; please limit the total attachment volume to less than 25 pages. Responses must include the following: - name and address of firm - size of business - CAGE code and/or DUNS Number. It is emphasized that the requested information is for preliminary planning purposes only and does not constitute a commitment, implied or otherwise, that NASA will solicit for such a procurement in the future. The Government is not responsible for any costs incurred in furnishing this information. Respondents are advised that NASA is under no obligation to acknowledge receipt of the information received or provide feedback to respondents with respect to any information submitted under this RFI. NASA may contact respondents to this RFI if clarifications or additional information is desired. Response requested by 4:30 p.m. EST on June 30, 2016 Interested firms should submit RFI responses and any routine communications concerning this notice to Ms. Ceseley Dunbar ceseley.dunbar@nasa.gov. Technical questions may be addressed to Mr. Scott Belbin at scott.p.belbin@nasa.gov. Additional Background Information for ARRM: NASA is developing a first-ever robotic mission, called the Asteroid Redirect Robotic Mission (ARRM), to visit a large near-Earth asteroid, collect a multi-ton boulder from its surface, and redirect it into a stable orbit around the moon. Once it's there, astronauts will explore it and return with samples in the 2020s as part of the follow-on Asteroid Redirect Crewed Mission (ARCM). The combination of these two missions, along with a third element to detect and characterize potential target asteroids, is called the Asteroid Redirect Mission (ARM). This Asteroid Redirect Mission (ARM) is part of NASA's plan to advance the new technologies and spaceflight experience needed for a human mission to the Martian system in the 2030s, and as well, other future human and robotic missions.
