研制了一种用于螺旋桨性能试验的滚动试验台。介绍的滚动试验台用于梅兹利克27x12螺旋桨的性能测试，该螺旋桨用于UIUC航空试验台和UIUC小型苏霍伊无人机。为螺旋桨测量的性能参数将在未来用于帮助计算这些飞机的气动系数。为了得到螺旋桨的推力和扭矩与转速的关系曲线，以及推力系数、功率系数和效率曲线，对滚动试验台进行了流量、螺旋桨转速、推力、扭矩、空气温度和气压的测量。该平台安装在车辆上，其设计和制造是为了便于携带，因此它由三个子组件组成：一个平台、一个笼罩的垂直梁和一个测试仪器。滚动试验台经过了广泛的初步测试，包括模拟推力和扭矩校准、热成像和流动可视化。给出了螺旋桨在0-60英里/小时流速下的实验结果。
A rolling rig for propeller performance testing was developed. The rolling rig presented was used for performance testing of a Mejzlik 27 x 12 TH propeller, which is used on the UIUC AeroTestbed and the UIUC Subscale Sukhoi unmanned research aircraft. The performance parameters measured for the propeller will be used in the future to aid in the calculation of the aerodynamic coefficients of these aircraft. The rolling rig was instrumented to measure flow speed, propeller rotation rate, thrust, torque, air temperature, and air pressure, in order to find the thrust and torque vs. rotation rate curves as well the thrust coefficient, power coefficient, efficiency curves for the propeller. The rig, which is mounted onto a vehicle, was designed and fabricated to be portable such that it is assembled of three sub-assemblies: a platform, a shrouded vertical beam, and a testing apparatus. The rolling rig underwent extensive initial testing including simulated thrust and torque calibration, thermal imaging, and flow visualization. Results for the propeller from experiments performed at flow speeds of 0–60 mph are presented.
