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.
