| 摘 要： | 由于自由飞模型的试验雷诺数较低而产生了尺度效应,为探论某种四发水上飞机自由飞模型升降舵偏角的模拟和修正,本文叙述了该尾翼的风洞试验,并加以分析比较,初步得出多种模型与预测的舵偏角之间的舵偏等效线,以便在试验和预测中选用。这种试验方法和结果对其它形式的模型试验也有一定的参考价值。

| Abstract: | Because of lower Reynolds number in free-flight modeltest scale effect is produced.Wind tunnel test of the tail is describedin this paper so as to study simulation and correction of elevator an-gle for a seaplane free-flight model powered with four engines.Afteranalyses and comparisons equifinal lines of the elevator angle betweenmodel and preestimate are obtained preliminary.The lines can be cho-sen in test and preestimate. This method and results also possese somereference value for other model tests. |
