Abstract: According to the requirement of frequently estimation and adjustment of weight and c.g. (center of gravity) during aircraft conceptual design, a method based on 3-D parametric modeling is proposed to realize rapid weight and c.g. estimation and adjustment by editing relevant parameters. Based on the method, the parameters used for describe the model and the process of modeling is decided by analyzing the object and logic of aircraft modeling, so that the system used for model design and weight analysis can be developed. At last, a case study is presented to show the procedure of weight and c.g. estimation using the method proposed by this paper.
