ABSTRACT:
In an uncooled engine, it is propose to form insulator coatings on the combustion chamber surfaces, and to mechanically protect such coatings against erosion or cracking by means of outer protective layers applied over the insulator coatings. The insulator coatings can be zirconium oxide applied to a thickness of approximately 0.15 inch. The protective layers can be formed of various materials resistant to high temperatures in the vicinity of 2000.degree. F., e.g. silicon nitride, steel or cast iron.
