A method of producing high aspect ratio domes by vapor deposition

摘要

An apparatus and method for preparing high aspect ratio domes employed to enhance aerodynamic performance in missiles and aircraft. The apparatus and method of the present invention also provide transmissive domes for infrared sensors used for navigation, targeting and guidance systems. The apparatus is employed in chemical vapor deposition furnaces for chemical deposition of materials on mandrels to form domes. The mandrels of the apparatus are arranged in the deposition chamber such that the flow of gaseous reactants does not impinge on the mandrels. The reactants diffuse onto the mandrels to form domes with high aspect ratios.
