Aircraft Parameter Design And Software Development

The Aircraft Conceptual Design is a whole design process. It proceeds from Conceptual Design phase to Preliminary Design Phase with the purpose of offering a optimal aircraft project. The process of determining aircraft parameters is very intricate. It needs experience and iteration. So it costs a lot of time.If a suit of design software has been developed, not only the weary calculation and the iteration can be avoided, but also one or several preliminary concept meeting the design requirements can be brought forward in a short time. With the cycle of the aircraft design shortened, the cost will be saved. So it is very important to study the software about the General Aircraft Design.The software approaching to accomplish the procedure is discussed in this paper, and the content about the graphic user interface is also involved. The analysis program is scheduled according to the varieties of the aircraft. And the preliminary conceptual design meeting to the design requirements is advanced. To prove the precision and the practicability of the software, three types of aircraft such as civil jet transport, jet fighter and military transport is concerned. The results of test cases indicate that the final design parameter of the software is near to the facts. So it is convenient and reliable to use.
