What are the temperature constraints on various solid boosters/launchers; what are the lowest and highest temperatures they can tolerate? (One answer per booster/launcher/stage)

Shuttle Solid Rocket Boosters (SRBs) had a set of specification limits and a set of certified use limits on Propellant Mean Bulk Temperature

  • The specification limits were 40°F to 90°F.
  • The certification limits were 50°F to 82°F.

From NSTS 07700 VOLUME X – BOOK 1 (November 1998) Flight and Ground System Specification, Book 1, Requirements

The following parameters shall define the performance of the SRB over the PMBT range from 40°F to 90°F unless otherwise noted. For the purpose of systems analysis and generation of design/certification environments, a PMBT range from 50°F to 82°F shall be used.

On one of the flights I worked on, the manufacturer's prediction for the PMBT for a July launch was 83°F which resulted in a bunch of meetings and paperwork.

  • $\begingroup$ @PcMan the death of 7 people was hardly "fireworks" Also, the limits may have been different then. I quoted the 2008 numbers. $\endgroup$ Jun 29 at 12:27
