Review of Test Data Indicates Conservatism for Tile

Penetration • The existing SOFI on tile test data used to create Crater

was reviewed along with STS-87 Southwest Research data

- Crater overpredicted penetration of tile coating

significantly

Initial penetration to described by normal velocity

Varies with volume/mass of projectile (e.g. 200 ft/sec for

3 cu.In) Significant energy is required for the softer SOFI particle

to penetrate the relatively hard tile coating

Test results do show that it is possible at sufficient mass

and velocity

Conversely, once tile is penetrated SOFI can cause

significant damage

Minor variations in total energy (above penetration level)

can cause significant tile damage

- Flight condition is significantly outside of test database

Volume of ramp is 1920cu in vs 3 cu in for test
