The invention discloses a detachable oil tank of a dual-mode take-off and landing unmanned aerial vehicle and a connecting structure and a reloading method thereof, and belongs to the field of unmanned aerial vehicles. Wherein the detachable oil tank serves as an auxiliary oil tank of the unmanned aerial vehicle and is detachably mounted in a parachute bay of a dual-mode take-off and landing man-machine, and an oil interchange pipeline and a ventilation pipeline which are communicated with a main oil tank of the unmanned aerial vehicle are arranged on the detachable oil tank. According to the flight requirements of the dual-mode take-off and landing unmanned aerial vehicle, a detachable oil tank is selectively installed, in a zero-length launching mode, the detachable oil tank and a ventilation pipeline are not installed, an oil stringing pipeline is not connected, and a recovery parachute is arranged in a parachute bay; in the skating mode, the detachable oil tank is used for replacing the recovery umbrella, the ventilation pipeline is installed, and the oil serial pipeline is connected. The space is effectively utilized, the detachable oil tank is used for replacing the dead weight of the recovery umbrella in a skating mode, the maximum voyage and endurance can be improved, and the gravity center problem caused by directly disassembling the recovery umbrella is avoided. The dual-mode take-off and landing unmanned aerial vehicle is convenient to assemble and disassemble, and free switching between a zero-length launching mode and a taxiing mode can be achieved.
本发明一种双模起降无人机可拆卸油箱及其连接结构、换装方法,属于无人机领域。其中可拆卸油箱作为无人机副油箱,可拆卸安装于双模起降为人机的伞舱内,可拆卸油箱上设置与无人机主油箱连通的串油管路和通气管路。根据双模起降无人机飞行需求进行可拆卸油箱的选装:零长发射模式下,不安装可拆卸油箱和通气管路,串油管路不接通,伞舱内为回收伞;在滑跑模式下,用可拆卸油箱替换回收伞,安装通气管路,接通串油管路。本发明有效利用空间,用可拆卸油箱替换滑跑模式下的回收伞死重,有利于提高最大航程和航时,又避免直接拆除回收伞带来的重心问题。本发明装拆方便,可实现双模起降无人机零长发射模式、滑跑模式的自由切换。
