为了在飞机概念设计过程中给新型号的设计要求组织和基本参数估算提供便捷且可扩展的工具而开发了设计要求与初步定参数环境 (EDRIPS)。在这一环境中 ,设计者可以通过友好的用户界面交互地输入飞机的性能要求、构造任务剖面和选取有效载荷 ,然后以此为基础从约束分析所得的可行域中选取设计点 ,进而利用一种改进的估算飞机起飞重量的方法进行任务分析以得到飞机的基本设计参数。介绍了各模块的实现措施和所采用的方法。最后通过对一个设计实例的分析验证了 EDRIPS应用于飞机概念设计的有效性和可靠性
Design Requirements and Preliminary Parametric Environments (EDRIPS) were developed to provide a convenient and scalable tool for the design of new models of design requirements organizations and basic parameters during aircraft conceptual design. In this environment, designers can interactively input aircraft performance requirements, construct task profiles and select payloads through a user-friendly interface, and then use this as a basis to select design points from feasible domains resulting from constraint analysis, Improved method of estimating aircraft take-off weight for mission analysis to obtain the basic design parameters of the aircraft. The implementation of each module and the method adopted are introduced. Finally, through the analysis of a design example, the validity and reliability of EDRIPS applied to the conceptual design of aircraft
