Request for Information
Question Set One

1. Is there an established budget yet?

This solicitation is for information only. No procurement action decisions have been planned yet.

2. Please provide material type or properties for the reference system fibrous ceramic TPS.

Please consider LI-2200 to be the design reference TPS. Properties are available at:

3. Does the 15 g acceleration apply to the Crew Module/Service Module separation joint or just the Crew Module during an ascent abort?

The Crew Module is currently expected to separate from the Service Module in the event of a 15g ascent abort.

4. Please define the transition point between the base heatshield and backshell.

The heatshield is currently expected to extend past the maximum diameter of the Crew Module. The current design locates the heatshield/backshell split line at the tangency point with the backshell aft cone, though the precise location of the split line has not been finalized.

5. Define performance, safety and durability criteria.

To understand the overall CEV performance and requirements please examine the CEV CFI Amendment, which can be found at the following URL:

For the LEO heatshield in particular we are currently evaluating the role of TPS in achieving flight rate and operability requirements. Inputs from responders on their suggested approaches for re-usability and durability are appreciated.

6. Can you provide the trajectory or the time history of the heat flux that produces the total heat load?

Please refer to the attached ISS Return Environments data package.

7. Can you provide information about follow-on procurement plans (schedule, number of awards, etc)?

This solicitation is for information only. No procurement actions have been planned yet.
