本文描述了一架小型特技飞机进行的大迎角飞行试验。一架35%比例、翼展2.6m(102英寸)的苏霍伊29 S电动飞机被开发并用于这项研究。这架飞机配备了定制的100赫兹传感器数据采集系统，该系统之前已经开发和测试过。这架飞机经过了几次失速和下降的障碍动作，在此期间，传感器数据采集系统记录了飞行数据。在机动过程中记录的飞行数据被用来产生飞机状态和气动系数的时间历史。首先对用于大迎角研究的类似特技无人机进行了简要的文献回顾。然后给出了飞机研制的背景和描述，以及飞机的规格。其次，介绍了用于分析试飞数据的数据分析方法。在此基础上，给出了初步试飞结果，包括飞行轨迹图、时间历程和飞机气动系数数据。最后给出了下一步工作的建议。
This paper describes initial high angle of attack flight testing performed by a subscale aerobatic aircraft. A 35% scale, 2.6 m (102 in) wingspan Sukhoi 29 S electric aircraft, the UIUC Subscale Sukhoi, was developed and used for this research. The aircraft was instrumented with a custom 100 Hz sensor data acquisition system, which had been previously developed and tested. The aircraft was flown through several stalls and descending harrier maneuvers during which flight data was recorded by the sensor data acquisition system. The flight data recorded during the maneuvers was used to produce time histories of aircraft state and aerodynamic coefficients. A brief literature review of similar aerobatic unmanned aircraft used for high angle of attack research is first presented. Then a background and a description of the development of the aircraft are given along with specifications. Next, information about data analysis methods used to analyze flight test data is given. After that, initial test flight results are presented, including flight path trajectory plots, time histories and aircraft aerodynamic coefficient data. Finally a list of proposed future work is given.
