The invention belongs to the technical field of aircraft atmospheric data measurement equipment, and particularly relates to an intelligent towing cone system for test flight calibration, which is used for calibrating flight parameters such as height and speed output by an aircraft atmospheric data system and providing a parameter correction basis. The dragging cone system comprises a static pressure tube, a tail cone body, an optical fiber sensor, a dragging structure and an optical fiber sensing analyzer. According to the invention, the length of the pressure gas circuit of the towed cone system can be shortened, the problem of pressure delay in the existing towed cone product can be solved, the real-time continuous measurement of the pressure of the towed cone system is realized, the dynamic flight calibration of atmospheric parameters is realized, and the test flight calibration efficiency is improved.

    本发明属于飞机大气数据测量设备技术领域,具体涉及一种试飞校准用智能式拖锥系统,用于校准飞机大气数据系统输出的高度、速度等飞行参数,提供参数修正依据。所述拖锥系统包括静压管、尾椎体、光纤传感器、拖拽结构、光纤传感分析仪共5部分组成。本发明能够缩短拖锥系统压力气路的长度,能够解决现有拖锥产品中压力延迟问题,实现拖锥系统压力的实时连续测量,实现大气参数的动态飞行校准,提高试飞校准效率。
