Title The certain type of missile general structure design and analysis of aerodynamic parameters
Abstract
Developed in this paper， the former Soviet union "Sam - 2" missile as an example， with reference to the northwestern polytechnical university courses - missile overall structure design， design specifications， combing the related data and text of articles， in order to set up suitable for surface to air missile overall 3 d model of rapid design of pneumatic， including power system adopts the integral solid rocket ramjet.
This research mainly concentrated in the following aspects：
1. Improved the exquisite course of northwestern polytechnical university - missile overall structure design， design specification of aerodynamic shape model， and the related data and information for validation， and indicate the source；
2. According to relevant data， using SolidWorks software for 3 d modeling， 3 d model is established. And according to the model， the fast accurate missile aerodynamic performance parameters are given；
3. At last， using software Datcom to estimate the aerodynamic force of accuracy， input basic parameters based on the three-dimensional model， according to the corresponding program， the output of aerodynamic parameters， and report to and get the corresponding results.
Analysis causes of the error， pointed out the direction for future development. The development of our country has important reference value for surface to air missile.
Keywords：Missile overall structure design 3D modeling Aerodynamic forecast surface-to-air missile
