In order to solve the conductive ring module's interference problems  measured the electromagnetic radiation of Power drive module  and used test results analysis the electromagnetic compatibility of the conductive ring  identified and implemented appropriate EMC (electromagnetic compatibility) measures. When optical tracking system working  test equipment can not be fixed. Therefore  from the electromagnetic radiation theory  the paper analyzed the electromagnetic radiation of the power drive module. From it  determine the EMC pre-compliance test method for electromagnetic radiation of power drive module. Based on Test results  calculate the interference voltage of wire in Conductive ring  and then determine the corresponding EMC method. The results show that  when The power drive module Radiate Electromagnetic waves  wires would coupled common mode interference voltage  its frequency is 3MHz  amplitude is about 10V  it would interfered the operation of sensor. By reducing the area of ground loops  used shielded cables  final rule out the interference. 2010 IEEE.

Anti-radiation TSC695F is usually used as aerospace payload controller in tasks to ensure the aerospace payload having extremely high reliability in abominable space environment. The processor bases on SP ARC V7 architecture with parity check and EDAC  so it could design out high reliable bootstrap loader to guarantee the operation system of VxWorks and application codes loaded correctly and worked stable and high effective. First  this paper put forward the system hardware composition and boot mode which apply for aerospace payload  then it makes clear the related contents of register group initialization  stack initialization  system hardware initialization in bootstrap loader of TSC695F and give out the method to establish TRAP table. That's all through comparing different type of organize mode of program image. After that  compiling of target codes have been described and the kernel code of MakeFile had been given at the same time for reference aimed at the realization of engineering. Although this paper is based on TSC695F  but it could be extended to other embedded system based on SP ARC for bootstrap loader analysis and design  for example  the TSC697 which based on SP ARC V8 with higher performance  so this paper has extremely high engineering value. 2010 IEEE.

A review of high-speed flow pressure and aerodynamic heating effect on Supersonic missile's dome is given. The dome should have excellent properties in optical  mechanical and chemical characteristics. A design of dome on supersonic mode is described according to tactical guide line of a missile. The dome made of quartz which is about 8mm thick and 141mm in window diameter. To check up the reliability of the dome  a reasonable finite element model (FEM) of dome is established  and a thermal-mechanical Analysis to the dome by finite element software NASTRAN has carried on  through these can obtained the distribution of temperature field and stress field when the speed is 2.3Ma. The results indicated that the stress was concentrated in the joint of the dome end and the Missile Section  and the maximum stress was 16.4Mpa. The stress of other nodes was smaller than the allowable stress of quartz glass. Reference to the results of the analysis  a lightweight revision to the dome structural dimension and a new method of dome fixing have put forward  which can reduce the stress concentration. 2009 SPIE.
