Title The Role of the TNO Free Jet Test Facility in Solid Fuel Ramjet Projectile Development
Abstract
In this paper, a thermal calculation research about the combustion of four kinds of typical solid fuels with the air is carried on respectively, through which the influence law of the engine performance parameters and chemical composition is acquired when air-fuel ratio and inlet air temperature change. the Finite Element Method (FEM) is applied to analyze the dynamic stress and strain distribution of 35mm solid ramjet assisted projectile. Every component of projectile is analyzed. These researches are using FEM software ABAQUS and make the high overload problems as background, which is common when the solid ramjet assisted projectile is launching. The structure, material and work property of solid ramjet assisted projectile are analyzed. Built up the calculation model of solid ramjet assisted projectile, and analyzed the influence of solid ramjet assisted projectile under loads in detail. Completed the simplification of load conditions and geometry structures. Established the 3D FEM models of ramjet assisted projectile and its components on the basis of real status. Took the material nonlinear, geometry nonlinear, and state nonlinear of models into account in modeling, and deal with the simplification of the model and the contact of the component nicely, and got some value results.
This paper provides a new method to analyze the intensity of launch. The result provides the gist for the design of ramjet assisted projectile in the intensity. It also makes a good foundation for the following research.
