Description
技术领域 technical field
本发明涉及一种空中悬停的航空飞行器。适用于通信、侦察、监测、雷达、无线电管理、电子对抗等无线电设备系统设置空基平台，提高无线电设备系统的“升空效益”。 The invention relates to an aerial vehicle hovering in the air. It is suitable for setting up space-based platforms for radio equipment systems such as communication, reconnaissance, monitoring, radar, radio management, and electronic countermeasures, and improving the "lift-off benefit" of radio equipment systems.
背景技术 Background technique
无线电波可视为直线传播。由于地球表面曲率的影响，无线电波的传输受到视距的限制。解决这一问题的有效方法，就是将无线电设备放置在升空平台上，增加其与地面的真实高度，以加大视距范围。这即是所谓的无线电设备“升空效益”。 Radio waves can be thought of as traveling in a straight line. Radio wave transmission is limited by line-of-sight due to the curvature of the Earth's surface. An effective way to solve this problem is to place the radio equipment on the lift-off platform and increase its true height from the ground to increase the line-of-sight range. This is the so-called "lift-off benefit" of radio equipment.
现有的升空平台主要有四类：固定翼飞机、垂直旋翼飞机、飞艇和系留气球。其中固定翼飞机、垂直旋翼飞机、飞艇由于需要自身携带燃料提供能源，因此留空时间不长，为装载的无线电设备提供能源受限。而系留气球则体积庞大，升降困难，有效载荷重量受限。 Existing lift-off platforms mainly contain four categories: fixed-wing aircraft, vertical rotor aircraft, airships and tethered balloons. Among them, fixed-wing aircraft, vertical rotor aircraft, and airships need to carry fuel to provide energy, so they are not left in the air for a long time, and the energy provided for the loaded radio equipment is limited. Tethered balloons are bulky, difficult to lift, and have limited payload weight.
近年来，以四旋翼为基础的多旋翼全电动无人机得到快速发展。多旋翼结构简单，控制灵活，飞行稳定，逐步从航模走向实用。但其现在均使用电池提供电能，受到非常大的制约，载荷能力和续航时间都十分有限。 In recent years, quadrotor-based multi-rotor all-electric UAVs have developed rapidly. The multi-rotor has a simple structure, flexible control, and stable flight, gradually moving from model aircraft to practical use. However, they all use batteries to provide electric energy, which is very restricted, and the load capacity and battery life are very limited.

具体实施方式 Detailed ways
本发明提供的实施例为一四螺旋桨系留旋翼升空平台系统。 The embodiment provided by the present invention is a four-propeller moored rotor lifting platform system.
参见图1、2，螺旋桨1与驱动电动机2相联结，将四个联结在一起的螺旋桨1和驱动电机2固定在升空平台支架3上面，系缆单元4一头固定在升空平台支架3上面，另外一头固定在地面保障单元5上面。地面保障单元5中的电源装置，通过系缆单元4中的电源线6，向驱动电动机2提供电能，驱动螺旋桨1产生升力。地面保障单元5中的飞控装置，通过系缆单元4中的多路光纤7，以线控的方式遥控升空平台的姿态和位置。系缆单元4中的避雷金属网8，提供了大电流避雷传输通道，保障升空平台在雷雨等恶劣气候条件下安全工作。
Referring to Figures 1 and 2, the propeller 1 is connected with the driving motor 2, and the four connected propellers 1 and the driving motor 2 are fixed on the support 3 of the lift-off platform, and one end of the mooring unit 4 is fixed on the support 3 of the lift-off platform , and the other end is fixed on the ground support unit 5. The power supply device in the ground support unit 5 provides electric energy to the driving motor 2 through the
本发明升空平台单元采用四旋翼飞行器原理作为动力子系统结构，即每个螺旋桨与一个驱动电动机相联结，由电机直接驱动螺旋桨产生升力，四个电机和螺旋桨的结构和直径都相同，由支架相联结呈十字交叉结构对称分布在前后、左右四个方向，其前后和左右两组螺旋桨的转动方向相反，以抵消陀螺效应和空气动力扭矩效应。通过分别调节四个电机转速，可改变每个螺旋桨所产生的升力，进而改变升空平台单元在空中的姿态和位置。 The lifting platform unit of the present invention adopts the principle of a four-rotor aircraft as the power subsystem structure, that is, each propeller is connected with a driving motor, and the propeller is directly driven by the motor to generate lift. The two sets of propellers rotate in opposite directions to offset the gyroscopic effect and the aerodynamic torque effect. By adjusting the rotation speed of the four motors separately, the lift generated by each propeller can be changed, thereby changing the attitude and position of the lift-off platform unit in the air.
本发明的驱动电动机使用270伏直流电压的直流无刷电动机。在飞控子系统的控制下，直流无刷电机可有效地、灵活地、无极改变螺旋桨的转速，从而及时调整升空平台的飞行状态和空中位置，实现升空平台的起降、悬停、随行等性能。为适应航空电源标准化，选择使用270伏直流电压的直流无刷电动机。 The driving motor of the present invention uses a DC brushless motor with a DC voltage of 270 volts. Under the control of the flight control subsystem, the brushless DC motor can effectively, flexibly, and steplessly change the speed of the propeller, thereby adjusting the flight state and air position of the lift-off platform in time, and realizing the take-off and landing, hovering, Accompanying and other performance. In order to adapt to the standardization of aviation power supply, a DC brushless motor with a DC voltage of 270 volts is selected.
本发明系缆单元采用600伏或600伏以上电压的高压电源线。高压传输电能是为了减小系缆电源线中的电流，从而可减小电源导线的截面积，减轻系缆单元的重量。 The mooring unit of the present invention adopts a high-voltage power cord with a voltage of 600 volts or more. The purpose of high-voltage transmission of electric energy is to reduce the current in the power cord of the tether, thereby reducing the cross-sectional area of the power conductor and reducing the weight of the tether unit.
本发明系缆单元设置有多路光纤信号传输线。光纤信号传输线为升空平台单元中的飞行控制部分提供了一种线控方式，可极大减少对遥控线路的干扰。同时，光纤信号传输线还可为任务载荷的无线电设备提供宽带信号通道，可使无线电设备仅仅将高频部分装载在升空平台上，减少了升空平台的任务载荷重量。 The mooring unit of the present invention is provided with multiple optical fiber signal transmission lines. The optical fiber signal transmission line provides a wire control method for the flight control part of the lift-off platform unit, which can greatly reduce the interference to the remote control line. At the same time, the optical fiber signal transmission line can also provide a broadband signal channel for the radio equipment of the mission load, so that the radio equipment can only load the high-frequency part on the lift-off platform, reducing the load weight of the lift-off platform.
本发明系缆单元设置有大电流避雷传输通道。大电流避雷传输通道是为升空平台在雷雨等恶劣的气候下安全使用设置的。 The mooring unit of the present invention is provided with a large current lightning protection transmission channel. The high-current lightning protection transmission channel is set for the safe use of the lift-off platform in severe weather such as thunderstorms.
