Flight Set 360l009 (Sts-36) Case and Seals Component, Volume 2

By: Nasa, National Aeronautics and Space Adm

The performance of the 360L009, Ninth Flight, Redesigned Solid Rocket Motors (RSRM) is assessed in respect to case hardware and joint sealing issues as seen from post-fire assessment of the case and seals. In addition, all of the potential anomalies have been classified and summarized. The post-fire assessment of both motors showed the case segments to be in good condition. Field joint fretting of this flight set ranged from light on most of the joints to locally heavy on three of the joints. The LH aft field joint is the most heavily fretted joint to date; this joint had previously fretted areas from STS-27. No new fretting was found in old fretting locations. However, new frets were found at the edges of repaired areas on both the LH center and aft field joints. All fretting was mapped from the inner clevis leg. The capture feature fretting was not mapped due to the difficulty of measuring the fretting in the capture feature region. It is assumed that the capture feature had damage similar to that on the inner clevis leg. Carlisle, Alan R. Unspecified Center...
