This study presents the design and development of servo stabilization system for airborne applications in specific missile and radar applications.The main objective was to study the stability of the loads and structural analysis of the Servo Stabilization system. The major significance of this design is to withstand the payload with respective to dynamic conditions. To initiate this approach, several methods were applied to achieve better performance. Geared Servo Mechanism, Linkage Mechanism, Direct Drive Mechanisms each have their own advantages and disadvantages.The geared servo systems had a minimum back lash among them. If the LOS angle disturbs, it will lead to reduction in the tracking accuracy. Based on the practical experiences and literature survey, Direct Drive stabilization was selected and analysis carried out to meet the specifications. Direct Drive servo system was preferred for the project to avoid the back lash of the gears. The servo stabilization system contains Mechanical components like linkages, Payload carrier (Antenna Servo interface Plate), bearings etc., Electrical components like BLDC Motors and Drivers. The feedback sensors were selected based on the accuracy which plays a key role in the tracking. Before realizing the hardware implementation, a full scale CAD model had been developed in solid works and analysis process done for structure using Ansys. The main concentration on Antenna servo interface plate which has a high severity to withstand the particular load as per the design thickness 2mm was maintained for aluminum which was not satisfactory. To increase the stiffness of the system, different material were chosen like EN 24 and EN8 for the analysis to satisfy the responses. The study is organized as follows, it begins with the introduction and design specifications of the system; explores the selection of servo Mechanism and material and design considerations; Design Methodology; and finally ended with results and conclusion.

Key words: Servo stabilization, gimbal, azimuth, elevation, direct drive, gear mechanism, linkage, pivot, payload, bulk-head, los, backlash, tracking accuracy, angular freedom.
