Abstract

Optical fairing is one of the key components of the missile , which can improve the aerodynamic characteristics of the missile , and can play a role in protection of its internal optical system . Precision connection between the fairing and the shell structure can ensure the tightness of the optical compartment . In the fairing manufacturing process, due to the limitations of process design , some of the fairing reference size may tighten the tolerance zone or offset , which will bring a series of manufacturing and inspection issues . This paper first outlines the optical fairing shape structure, explained the significance of the edge width control precision. Secondly, Manufacturing process for the fairing is made a brief introduction. On this basis , analyzes the relationship between the relevant linear dimensions , and uses the formula defines the numerical relationship between the main parameters . Finally , the various sources of error are analyzed, and a method to determine the width of the edge of the tolerance range is put forward. This method can effectively achieve spherical fairing edge width tolerance, its findings apply equally meniscus lens with the platform structure.
