ABSTRACT:
Sewn, quilted ceramic blankets (AFRSI) and integrally woven core insulation systems (TABI) were examined in a 170 decibel aeroacoustic environment under oscillating air loads. Preconditioning in a radiant heat source was done at both 2000.degree. F. and 2500.degree. F. before testing. A multi-layer ceramic weave construction based on an angle interlock weave architecture is superior over all other TPS systems examined. These configurations do not require a surface coating to enhance survivability. Single-ply TABI fabric surfaces using an insulated integrally woven core structure survive up to 2000.degree. F. without the use of a ceramic coating to toughen the surface to the aeroacoustic noise level. AFRSI blankets of the art require a ceramic coating in order to demonstrate comparable performance after exposure to a 2000.degree. F. radiant heat temperature.
