Unmanned aerial vehicle oil supply method and system capable of measuring oil consumption

The invention discloses an unmanned aerial vehicle oil supply method and system capable of measuring oil consumption. The method comprises steps that a flow sensor (3) and an auxiliary oil tank (2) are sequentially arranged on a pipeline for supplying oil to an engine (5) from a main oil tank (1), the flow sensor (3) is used for metering the amount of oil flowing through the pipeline, and the auxiliary oil tank (2) is used for taking the oil from the main oil tank (1) in a negative pressure mode and storing gas entering the auxiliary oil tank (2) through the pipeline. The device has advantagesof accurately monitoring the measurement of the unmanned aerial vehicle, guaranteeing the stable and reliable oil supply for the engine, and the like. 本发明公开了一种可测量用油量的无人机供油方法及系统，方法包括：在主油箱(1)向发动机(5)供油的管路上依次设置流量传感器(3)和副油箱(2)，流量传感器(3)用于对所述管路中流过的油量进行计量，所述副油箱(2)用于通过负压方式从所述主油箱(1)取油，并存储通过所述管路进入到副油箱(2)内的气体。具有既可以准确监测无人机的测量，又能保证为发动机稳定、可靠供油等优点。
