摘要

对中端市场飞机的外形进行研究是未来飞机设计中最有前途的研究方向。本研究旨在探讨飞机设计技术的优越性，从而减少总重量和增加结构完整性。利用多元线性回归方法，给出了宽体运输机最大起飞重量的估计方法。对26种不同的中端市场飞机的设计配置、推进系统、性能特征和结构完整性参数进行了实时案例研究。此外，为了验证MTOW模型的有效性，还进行了灵敏度分析。模型拟合最佳，R2 = 0.9676。这个R2结果比文献中获得的最低R2高5%左右。此外，对未来飞机设计提出了明确的见解和管理观点。

Structural Weight Prediction Modelling for a Wide-body Aircraft by Implementing Real-time Case Study

Research studies on portraits of the middle-of-the-market aircraft are the most promising research for future aircraft design. This research aims to investigate the superiority of aircraft design technology, which results in reduced gross weight and increased structural integrity. Using a multi-linear regression method, this article offers to estimate the Maximum Take-Off Weight (MTOW) for wide-body transport aircraft. A real-time case study is carried out for the design configurations, propulsive systems, performance characteristics and structural integrity parameters of 26 distinct middle-of-the-market aircraft. Furthermore, a sensitivity analysis is carried out in order to validate the MTOW model. The model provides the best fitness with R2 = 0.9676. This R2 result is around 5% higher than the lowest R2 achieved from the literature. In addition, a clear-cut insights and managerial views towards future aircraft design are discussed.
