双座轻型飞机总体与性能参数相关性分析

Correlation Analysis of General and Performance Parameters of Two-Seater Light Aircraft

摘要: 在飞机概念设计阶段，总体参数与性能参数的确定依赖于已有型号的统计规律。为建立反映当前技术条件下双座轻型飞机设计参数之间的关系，本文基于飞机设计基本原理，收集了183款国内外现役双座轻型飞机的总体参数与性能参数数据。通过对参数进行对数化处理与回归分析，建立了参数间的数学关系，并明确了双座轻型飞机主要设计参数的典型取值范围。结果表明，空机重量、机翼面积、发动机功率等总体参数与起飞总重之间存在较强的相关性；失速速度与翼载荷、最大平飞速度与翼载荷之间也呈现良好的统计规律。以某型双座飞机为例进行验证，估算值与实际值吻合较好。本文所得经验公式与统计数据可为双座轻型飞机的概念设计提供实用的设计依据与参考。

Abstract: In aircraft conceptual design, the determination of general and performance parameters relies on statistical data from existing aircraft. To establish quantitative relationships for two-seater light aircraft under current technological conditions, this study collects data from 183 existing two-seater light aircraft. Through logarithmic transformation and regression analysis, mathematical relationships between parameters are established, and typical value ranges of key design parameters are identified. Results show that general parameters such as empty weight, wing area, and engine power correlate strongly with maximum takeoff weight; stall speed correlates well with wing loading, as does maximum level flight speed. Validation with a typical two-seater aircraft demonstrates good agreement between estimated and actual values. The empirical formulas and statistical data provide practical references for the conceptual design of two-seater light aircraft.
