Research On Azimuth Aiming System Of Comme-frame Vertical Launce Of Submarine-launced Missile

Along with submarine-launched missile weapons'uncreasing renewal, launching equipments of missiles alsohave obtained rapid development, and their performance immediately influce operational capabity of the entire weapon system. But as the space of submarine is limit, it's difficult to install many kinds of missiles such as anti-aircraft missile, anti-ship missile, anti-submarine and attack missile. Launching missiles of many different uses with one lauching system can be implement by ultilizing comme-frame vertical launch technology, and the the aim of increasing the operational capability of the weapon system can be achieved. Azimuth aiming system is one of the most important parts of launching system; it has significant influence to the performace of the entire launching equipment and the attack precision of the missile.According to the requirements of the aiming system followed by the layout of submarine-launched missile comme-frame vertical launce technology, the general architectureis presented. Procedure analysis of inertial navigator and reference prism, vertical reflex light-tube, reference transition,horizontal reflex light-tube and photoelectric receiver which are the components of azimuth aiming system have been done.The azimuth aiming system analysis method is represented, and coordinate system and mathematic equation of elements which has connection with aiming are set up. Mathmatic models of azimuth deflection and its estimative error calculation are derived through coordinate conversation. Two kinds of azimuth estimative deflection (by direct calcualtion analysis and correction calculation analysis) by Monte Carlo method according the above mathematic model are calculated. The azimuth aiming error is got by combining the error analysis of azimuth transimission. The mean squre root areσ=16.34″(for correction calculation analysis) andσ=24.74″(for direct calculation analysis).
