The Simulation Research of Naval Gun Firing and Fire Control System
The shooting of naval guns is a complicated process with instantaneousness, high energy and strong impact. During the process, the influence of the vibration of the gun’s structure and the impact enforced on it are obvious and non-ignorable. Therefore, it is important to analyze and research the dynamic response of the artillery system, and it [...]
Simulation and Safety Evaluation of Fragments Impacting Shielded Explosive
To carry out the research about the issue of shock and initiation plays an important role in avoiding the happening of accidents for high-explosive weapons in the process of production, transportation and storage. In addition, as the main damage way of anti-missile technology, using high-speed fragments to detonate the incoming warhead is also the question [...]
Reliability and Optimization Design on Shell of Moving Supercavitation
Up to now, the cavitations phenomenon has been already experienced several generations’understanding and researching since discovered. The first supercavitating torpedo was manufactured by Russia, which aroused the fever of study the supercavitation in many countries. The main contributions of this thesis are as follows:A brief review of the development of supercavitation profile in countries was [...]
Heat Flux Optimization on the Stagnation Point of Reentry Missile Head in Hypersonic Flow
Aerodynamic heating is unavoidable when space vehicle reentry the atmosphere, it is a crucial task to do this research for Providing ample theory and data for reentry technology.As the missile head re-entry process, the sharp increasing of a gas temperature in compression wave layer is made the large kinetic energy transformed. Thus the heat flux [...]

Design and Realization of Launcher Integrated Test System Based on DSP and FPGA
With the improvement of modern weaponry performance,the real-time , speed and capacity of testing of separate instrument can’t be satisfied with the requirements of the testing system. To meet the requirement of measuring a kind of launcher,a test system to measure its performance was developed. The test system is based on virtual instrument technology,which not [...]
High-g Impact Test Value of the Research of Key Technologies
In this thesis, the following two aspects of researches are performed about the acceleration on-board memory test in high g shock. First, the on-board electron apparatus (such as on-board test circuit module) and its mitigation protection technology; Second, the study on the Battery of anti-high overload characteristics.The aims of this paper are to research the [...]
Dynamic Parameters Measurement and Attitude Simulation for the Cluster Fired by Combustion Gasbag
The dynamic parameters of the flight object, including artificial earth satellite, cluster, etc., are very important for performance analysis. Those parameters can provide aided performance and fault analysis, and provide the important foundation for verifying and optimization design, play an important role for finalizing the design, checking and accepting the flight body.Aiming at the problem [...]
Algorithm Design for Planar Missile Guidance
Along with the science and technology development, in the air fight the goal mobility strengthens day by day, if the missile use some classical guidance laws to intercept greatly mobile goal, obviously cannot satisfy the request.The future rencountre urgent need a guidance law which is able to adapt the more complex operational environment, therefore, it [...]
