Aerodynamic And Structural Design Of Small Cruise Missile

As a precision guided weapon system with long flight range,long air detention time,and the ability to launch from multiple platforms,cruise missile plays an indelible role in today’s informationalized,remote,and precision warfare.Therefore,various countries have invested a lot of manpower and material resources in the research and development of cruise missile,and committed to developing a cost-effective,comprehensive,and reliable cruise missile.In this paper,the aerodynamic shape and structure of a small patrol missile with collapsible wings and cylindrical launch method are designed.The following researches are carried out: the overall aerodynamic configuration scheme and structure of the patrol missile are designed,and the comparative analysis is carried out,the aerodynamic simulation calculation and analysis are carried out for various projectile body schemes respectively,and the comparative analysis are carried out for different main wing single row wing layout,tandem wing layout and tail aerodynamic layout,and the two sets of patrol missile aerodynamic configuration schemes are determined.The grid model of patrol missile with different schemes is established,and the lift coefficient,drag coefficient and lift to drag ratio of two aerodynamic models of patrol missile are obtained by hydrodynamics calculation.The more suitable aerodynamic configuration scheme of patrol missile is analyzed and optimized.According to the optimization scheme,the aerodynamic characteristics of the patrol missile are studied,and the aerodynamic simulation calculation and analysis of the different rudder Angle,attack Angle and deployment process of the patrol missile are carried out,which proves the rationality of the aerodynamic shape design scheme of the patrol missile.The Simulink model is established according to the elastic force and moment formula,kinematic equation and dynamic equation of patrol missile,and the motion trajectory of patrol missile is obtained by inputting the aerodynamic simulation data of patrol missile in different attitudes,and judging whether the flight state of patrol missile is stable.
