摘 要: | 为减少飞机设计过程中的不必要的硬件更改,提出了飞机初步设计阶段基于模型的设计思路。通过一个1/4风笛手J-3幼兽无人机的实例,说明如何通过DATCOM优化一个飞机结构设计、计算出气动特性,并提前分析所选择特定结构外形的飞机起飞着陆等性能,以提前预估所设计的飞机是否能够满足或基本满足设计要求。分析表明,基于模型的设计过程能够在一种快速可重复的模式下进行,能够很好控制飞机设计过程中的成本。

Preliminary Design of Aircraft Based on DATCOM |

Abstract: | In order to reduce unnecessary hardware changes during the aircraft design process, a model based design approach is proposed for the preliminary design of the aircraft. The 1/4 Piper J-3 Cub is used as an example to illustrate how to optimize an aircraft geometric design,calculate aerodynamic char-acteristics,and analyze the selected aircraft take-off and landing performance etc in advance based on selected aircraft geometric configuration,thus to estimate if the designed aircraft is able to satisfy or basi-cally meet design requirements. Analysis shows that all process of the model based method is accom-plished in a rapid and repeatable model,and so the cost of the aircraft design process can be well con-trolled. |
