摘要
本文论述了研究尾旋模型自由飞试验所出现的尺度效应问题,对建立模型自由飞试验与飞机飞行试验之间相关性有重要意义;分析了尺度效应对模型自由飞失速/尾旋试验的影响;提出了一种考虑模型自由飞失速/尾旋试验尺度效应的工程估算方法。
The problem of scale effect arising in spin model freeflight tests is discussed.This can be of significance for setting up thecorrelation between model free flight tests and aircraft flight tests.The analysis of the influence of scale effect on model free flight stall/spin tests is given, and an engineering prediction method including thescale effect in model free flight stall/spin tests is proposed.
