The Conceptual Design Of A Certain Air-to-land Missile

The conceptual design of x-x air-to-land missile is discussed in this paper . Corresponding results are obtained through the development of the mass characteristic analysis software system, the design and property analysis of the propulsion system and the simulation of the trajectory, which will provide theoretical fundamentals and practical results for its further design .Firstly , this investigation begins with the development of the mass characteristic analysis software system. The standard library and assembly library of the missile's mass characteristic system are made through the components analysis of an integrated missile ,and the computing modeling are constructed .Then all required parts is grouped into an integrated missile and their mass characteristics is obtained .Based on the above theory ,the software is developed. And the software system is applied to the air-to-land missile studied in the paper successfully.Secondly, as an important part-propelling system is studied in chapter three of this paper . Turbojet engine is selected as propulsion system according to the practical situation. The work of this part ranges from design to characteristic analysis. The characteristic curves of engine in various situation are shown, which provides preparation for trajectory computation .In the following part, trajectory design and computation are given , including fight scheme and control & navigation laws .Through the design and computation , the profile of attack angle, trajectory angle and pitch angle are designed .These works provide theoretical fundamentals for dynamics analysis and practical trajectory design .Finally, the conclusion of the paper is given and the trend of the air-to-land missile is brought forward.
