翻译后摘要：本研究是一个基准测试，以帮助各种转子性能代码的发展。该研究包括同时进行叶片压力测量和叶尖涡流调查。测量了包括跨音速流态在内的大范围叶尖马赫数。当用作规定尾流升力面代码的输入时，测得的叶尖涡强度和几何形状允许有效的叶片载荷预测。它还表明，与适当的流入和边界层建模，超临界流状态可以准确地预测。
Abstract : The present study is a benchmark test to aid the development of various rotor performance codes. The study involves simultaneous blade pressure measurements and tip vortex surveys. Measurements were made for a wide range of tip Mach numbers including the transonic flow regime. The measured tip vortex strength and geometry permit effective blade loading predictions when used as input to a prescribed wake lifting surface code. It is also shown that with proper inflow and boundary layer modeling, the supercritical flow regime can be accurately predicted.
