Fracture behavior of ceramic dome port cover on air breathing engine using liquid and solid fuel propulsion system was carried out in this study. Fracture characteristics was tested and estimated using scaled model of ceramic dome port cover by Shock tube. Fracture behavior was obtained by the fracture pressure from pressure sensor and observed the scattering phenomena of fracture specimen using high speed camera. Results obtained from this study can be used in the base data of dome port cover design for an air breathing engine.

The objectives of this study are to evaluate mechanical properties of glass ceramic for dome port cover material o( the ramjet. Candidate material for dome port cover of the ramjet is selected the machinable glass ceramic(MACOR glass-filled ceramic, Corning Glass Works, code 9658). Static and dynamic fracture toughness tests were performed to evaluate the apparent fracture toughness of notched specimen.

The objectives of this study are to evaluate the dynamic fracture toughness of advance glass ceramics(MACOR glass-filled ceramic, Corning Glass Works) for dome port cover of the ramjet. Static and dynamic fracture toughness tests are performed using strain gage method in the variation of notch radii.
