The invention discloses an unmanned aerial vehicle fuel tank which comprises a main fuel tank body, a fuel tank cover and a fuel tank cover. An anti-bubble oil tank cavity; the anti-bubble oil tank cavity is located below the main oil tank and comprises an oil outlet, and the volume of the anti-bubble oil tank cavity is the fuel oil volume generated when an engine of the unmanned aerial vehicle works at the maximum continuous power for the first fixed time; and the anti-bubble oil tank cavity partition plate is connected with the main oil tank and the anti-bubble oil tank cavity and comprises a one-way valve, and fuel oil of the main oil tank flows into the anti-bubble oil tank cavity through the one-way valve. The unmanned aerial vehicle fuel tank is simple in structural form and high in integration level, and the problems of independent auxiliary fuel tank arrangement commonly adopted by an unmanned aerial vehicle and complexity and reliability of a system for multi-cavity pressurization control fuel transfer in the fuel tank are solved. The precipitation tank and the liquid discharge valve are arranged at the bottom of the oil tank for the relatively severe use and operation environment of the unmanned aerial vehicle, so that relative health of oil quality and long-term stability of engine operation are guaranteed.
本申请公开了一种无人机油箱,包括:主油箱,包括用于所述主油箱加油的加油口;防气泡油箱腔;位于所述主油箱下方,包括出油口,其中所述防气泡油箱腔的容积为所述无人机的发动机以最大连续功率工作第一固定时间的燃油容积;防气泡油箱腔隔板,连接所述主油箱和防气泡油箱腔,包括单向阀,所述主油箱的燃油通过所述单向阀流入所述防气泡油箱腔。申请无人机油箱结构形式简洁,集成度高,避免了无人机常采用的独立副油箱布置和油箱内部多腔室增压控制传递燃油的系统复杂和可靠性问题。针对无人机使用和运行环境相对恶劣的情况,油箱底部设置沉淀槽和放液阀,保证油液品质的相对健康和发动机运行的长期稳定。
