摘要：【中文】一种手动液压多点同步机构及其操作方法，包括第一手柄、第二手柄、手压泵、梭阀和液压缸；第一手柄和第二手柄均连接有手压泵，两个手压泵均连接到梭阀，梭阀连接到液压缸；解决了直升机多点吊挂投放系统在空中投放货物时，既能驱动多个货物挂钩同步投放又不会因货物挂钩随直升机摆动被损坏的关键性技术问题。 【EN】A manual hydraulic multipoint synchronous mechanism and an operation method thereof comprise a first handle, a second handle, a hand pump, a shuttle valve and a hydraulic cylinder; the first handle and the second handle are both connected with hand pumps, the two hand pumps are both connected to a shuttle valve, and the shuttle valve is connected to a hydraulic cylinder; the key technical problem that when the helicopter multipoint hanging and throwing system throws cargos in the air, a plurality of cargo hooks can be driven to synchronously throw in the air, and the cargo hooks cannot be damaged along with the swinging of the helicopter is solved.

摘要：【中文】一种接触件(1)，包括针体(11)和压接筒(12)，压接筒(12)为内部设置盲孔结构的圆管(122)，所述的接触件(1)还包括压接环(13)，压接环(13)结构为两端开口相通的圆形管，压接环(13)插入压接筒(12)的盲孔中。本发明通过设置压接环内置于压接筒内，压接环包裹导线线芯进行压接，使得接触件和导线连接可靠，接触件能够使用在更宽的温度范围，或者振动强烈的环境中。 【EN】The utility model provides a contact (1), includes needle body (11) and crimping section of thick bamboo (12), crimping section of thick bamboo (12) are inside pipe (122) that set up the blind hole structure, contact (1) still include crimping ring (13), crimping ring (13) structure is the communicating circular tube of both ends opening, crimping ring (13) insert in the blind hole of crimping section of thick bamboo (12). The crimping ring is arranged in the crimping barrel, and wraps the wire core for crimping, so that the contact and the wire are reliably connected, and the contact can be used in a wider temperature range or a strong vibration environment.

摘要：【中文】本发明公开了一种基于直升机吊挂投放系统放飞固定翼飞机的方法，属于属于直升机吊挂投放领域。本发明的方法，包括以下步骤：1)将固定翼飞机吊挂在电动挂钩上；2)直升机进行上升飞行，启动固定翼飞机的发动机并进入怠速状态，直至固定翼飞机到达或超过预设高度；3)直升机进行水平飞行，直至其飞行速度达到固定翼飞机起飞离地速度；4)当固定翼飞机的速度到达起飞离地速度时，对固定翼飞机的发动机开加力，直升机以相同的速度进行伴飞；5)当固定翼飞机速度在起飞安全速度以上时，将电动挂钩从固定翼飞机上脱离；6)直升机带动电动挂钩远离固定翼飞机，固定翼飞机进行自主飞行。本发明克服跑道损毁时固定翼飞机无法起飞的缺点。 【EN】The invention discloses a method for flying a fixed-wing aircraft based on a helicopter hanging and launching system, and belongs to the field of helicopter hanging and launching. The method comprises the following steps: 1) hanging the fixed-wing aircraft on an electric hook; 2) the helicopter flies in a rising way, starts an engine of the fixed-wing aircraft and enters an idling state until the fixed-wing aircraft reaches or exceeds a preset height; 3) the helicopter flies horizontally until the flying speed reaches the flying and ground clearance speed of the fixed wing airplane; 4) when the speed of the fixed-wing aircraft reaches the speed of flying off the ground, applying force to an engine of the fixed-wing aircraft, and accompanying the helicopter at the same speed; 5) when the speed of the fixed-wing aircraft is higher than the safe takeoff speed, the electric hook is separated from the fixed-wing aircraft; 6) the helicopter drives the electric hook to be far away from the fixed-wing airplane, and the fixed-wing airplane flies independently. The fixed wing aircraft overcomes the defect that the fixed wing aircraft cannot take off when the runway is damaged.
