Paper Abstract

The design and manufacture of a large chisel window assembly is reviewed, the intended application being for a mirror-stabilized narrow field of view thermal imager in a high speed aircraft. Aerodynamic heating was expected to be significant, and this placed restrictions on the choice of material and the configuration of the window assembly. The practical problems of procurement and manufacture are discussed, including material supply, edging, polishing, coating and assembly. The results of IR interferometric tests on individual panes and on the final assembly are presented. The window is shown to achieve diffraction-limited performance, while being capable of withstanding high temperature and pressures, and is resistant to rain erosion.
