New MPS Interface Block Foam (MPS/TPS)

Problem: The existing MPS TPS is a spray foam that requires extensive schedule and technician resources during each Orbiter flow. The spray foam has a relatively long cure time and requires area isolation and cleaning.
Solution: Implement precast foam MPS insulation instead of foamed in place insulation. Precast foam is easy to remove, install, is non-toxic and requires no cleaning. The foam pieces would be cast in a reuseable fiberglass clamshell type mold boot would be fabricated by vacuum bagging over a mandrel. Parts would be reuseable with spares available.
Initial Operation Date: Phase II Upgrade
June 1, 1999
Technology Goal: Precast foam is a mature technology that has been used throughout the thermal protection system.
Goals Supported: 1) Fly Safely
2) Meet the Manifest
3) Improve Supportability
4) Reduce Cost
