The invention belongs to the technical field of fixed-wing aircraft airborne fire extinguishing, and discloses an aerial water dropping fire extinguishing method for a fixed-wing aircraft. The method comprises the following steps that firstly, whether the aircraft is in a water dropping state or not is judged, a water dropping mode is selected to carry out water dropping operation after confirmation, an open state of a water dropping cabin door is judged in real time by a system, and judging is carried out according to time after water dropping is completed; the system automatically controls the water dropping cabin door to be closed and judges the closed state of the water dropping cabin door in real time, and finally the water dropping operation is finished. Mainly according to the aircraft performance and fire extinguishing safety characteristics of the fixed-wing aircraft, a set of control principles and operation procedures for controlling an aircraft low-altitude water-dropping cabin door to be retracted and released and the water dropping cabin door to be unlocked/locked are provided, the safety criterion of each operation step is defined, the cabin door is controlled to be unlocked through hydraulic energy, the water dropping cabin door is pressed open through the weight of water in a water tank, water flow is thrown out of the water tank, then the cabin door is controlled to be folded and locked through hydraulic energy, and therefore the purpose of safely and effectively dropping water to extinguish fire is achieved.
本发明属于固定翼飞机机载灭火技术领域,公开了一种固定翼飞机的空中投水灭火方法,首先判断飞机是否处于可以投水的状态,确认完毕后,选择投水模式进行投水操作,系统实时判断投水舱门打开的状态,完成投水后,根据时间判定,系统自动控制投水舱门关闭,并且系统实时判断投水舱门关闭的状态,最后结束投水操作。本发明主要根据固定翼飞机的飞机性能及灭火安全性特点,提出一套控制飞机低空投水舱门收放、投水舱门解锁/上锁的控制原理和操作流程,明确出每个操作步骤的安全判据,采用液压能源控制舱门解锁,借用水箱内水的自身重量压开投水舱门,将水流投出水箱,再采用液压能源控制舱门收上并上锁,从而达到安全有效投水灭火的目的。
