Title Design of 2D guided projectile collapsible wings and control system
Abstract
More and more precision guided ammo is consumed in modern war,the high price of precision guided ammo limits it`s using scale.reforming the traditional cannonball to endue it ability of ballistic correcting is a reasonable way to reduce the high cost of guided ammo .
First of all, this paper in reference to the analysis of all kinds of domestic and foreign two-dimensional trajectory correction projectile development on the basis of the design and that of two-dimensional trajectory correction projectile development are outlined, and the two-dimensional trajectory correction projectile key techniques are analyzed and discussed.
Secondly, the paper proposes the two-dimensional trajectory correction fuze open wing plate and the control system of the overall plan and design the concrete wing plate mechanism and open control mechanism by using three-dimensional design software. For the main stress components of the strength check, the feasibility of key motion are analyzed. The results show that movement of the body is feasible, to have a certain reference for the practical design.
The ANSYS fluid analysis software to open after the fuze wing of the two-dimensional trajectory correction projectile aerodynamic analysis, to study on the fuze wing in flight stress situation and influence of ballistic. For two-dimensional trajectory correction fuze fin optimization design provides a reference.
Keywords 2D trajectory correction Wing opening mechanism Wing design Aerodynamic analysis
