The target system for aerial defense artillery .has been widely used in the shooting training in aerial defense war. Since the performance of the target system has strong influence on the precision of the aerial defense shooting in the training process, the target system has been developed rapidly during the past decade. A novel target system has been proposed in this paper, the shooting principle is also put forward with some innovations and reasonable modification in the design process. In the system design part, the basic performance factors have been brought forward, including some necessary technical indicators and optimized design specification. Through the shooting test under the target system, a perfect performance has been obtained through observer glass experiments. The experiment results have strongly validated the rationalization and the reliability of the designed novel target system for aerial defense artillery.

Based on the current situation that the current ordnance equipment maintenance information management system is not intuitive, a new information system was designed and realized, which could display the two-dimensional Information and three-dimensional information synchronously. This system can well compatible with the existing one. Through studying the analysis of the original data structure, importing way for the 3D model of equipment, synchronous display for the 2D information and 3d model, the 3D information management system was realized, which provides a new digital method for equipment management person.

Cupped wave gyro’s mathematical modeling is derived via Hamilton principle, and the displacement equations and the nature frequency of gyro is determined by Galerkin method. Based on the modeling analysis and finite element method, the parameters of structure are optimized. The paper provides a reference in the design and fabrication of cupped wave gyro.
