Research of PnP Method Based on the Traditional Serial Bus Technology
With satellite technology maturing, for adapting to the space environment and accomplishing the space task, the technology of the On-Board Computer (OBC) platform has made great achievements in the continuing development. The research of the OBC bus has become an important subject in the field. At home and abroad, the research direction of the OBC [...]
The Research and Implementation of Small Satellite Attitude Simulation with Three-axis Turntable Controlled via the Internet
Space technology has become an important indication of one nation’s scientific and technological development and comprehensive national power; it is also an essential tools and methods of protecting national security. In order to make satellite complete its task quickly and accurately, the research and development of small satellites has boomed in the world since the [...]
Research and Application of Integration of VC and STK in Satellite Multi-disciplinary Optimization
In the design of satellite, many subsystems of it communicate and couple with each other tightly, so when some design parameters in a subsystem change, other parameters in other subsystem may do also. If simulation and optimization of the satellite only take place in one single system, the final results may be under greater separation; [...]
The Analysis of Flow Around the Spike Ahead of Hypersonic Blunt Body
Aircrafts or reusable space vehicles will encounter severe aerodynamic heating and shock drag when flying at supersonic speed. Taking into account the issue of aerodynamic heating, the hypersonic flight vehicles use the blunt-nosed body mostly, but the aerodynamic heating of blunt body is still very serious, and the strong bow shock ahead of the blunt [...]
Water Impact Simulation of Spacecraft Capsule and the Analysis of Its Factors Influence
As the last step of manned space activity, the return process of spacecraft is the final mark of the success of the mission. There will be a great impact force in the process of water landing, which will do harm to the cabin, the crew and related equipment. So the study on the water impact [...]
Experimental Research of Flat Plate CPL and Numerical Simulation for Evaporator
Space technology is one of the most popular and the fastest growing science in twenty-first century. Because of high-power and high heat flux electronic equipments widely used and space limitation on spacecrafts, traditional thermal control devices have been difficult to meet the requirements. In recent years, a sort of thermal control device (Capillary Pumped Loop) [...]
Fuzzy Control of an Unmanned Reconnaissance Plane to the Stability of the Platform at the Applied Research
In the Unmanned Aerial Vehicle(UAV) reconnaissance system, the optical sensors are usually installed on the stabilized platform in order to counteract the influence of angular motion of aircraft such that steady images can be acquired by optical sensors on UAV.This article introduces the UAV stabilized platform on the structure and principle, and then based on [...]
