Raad K. Automated designing of unmanned aerial vehicles (UAV)

This dissertation is devoted to the further development of the theory and processes of computer-aided design of UAV. The paper presents various classifications of the UAV and the LHC. There are identified two informative statement of the problem of designing the form UAV - designing a given DFD and projecting from the conditions of achievement the maximum effectiveness in accomplishing the task. Determined the most general decomposition of the task of designing the UAV's type. Completed functional-structural analysis of existing designs of UAV, there is shown the feasibility of the methods of constructing the search for the synthesis of struc-tural and layout scheme UAV. Investigated the observation of the UAV with a using of systemic approach. The component model of the UAV was builded, in which the UAV is provided in a vehicle with a complex multi-level hierarchical structure, which, in turn, is a vehicle of a higher level of hierarchy. Including the descriptions of basic functions of LHC and UAV were designed the func-tional structures of LHC, UAV and subsystems UAV in a view of graphs of the functional in-teraction, that form the basis for constructing the structural model of the set TR. There are additional functions identified on the base of the analysis of basic func-tions and functional elements of existing designs of the BAC and the UAV, as well as new features were synthesized and determined the device that implements the functional structures promising UAV and UAV control systems perspective. There are determined the most significant (in terms of solving the problem) design features, for the functional elements of the UAV and its subsystems related to the group of symptoms, the relation-ship and positioning of functional elements. Determined the local quality criteria for the problems of structural and parametric optimization. A method of multiobjective parameter optimization based on a systematic scanning (probing) of multidimensional domains point of the sequence is uniformly distributed in parameter space. It shown the connection test UAV design with aerodynamic coefficients. The method of calculating the basic geometric parameters of the UAV. The basic instrumen-tation to provide visual and intelligence information on the UAV. There is posed the problem of optimal choice of optical surveillance devices and the algo-rithm of its solution based on the use of the analytic hierarchy. The analysis of the integrative properties of CAD and the use of information tech-nologies at all stages of the life cycle of the UAV is completed. The structure of the software CAD UAV is designed. The description of interface is given.
