Embodiment 1

[0028] An example of a new mode of operation for drone cargo transportation.

[0029] The characteristic of drones used for cargo transportation is that they take off from A airport for loading and take off, and then land and unload at B airport.

[0030] At the take-off airport, the take-off of drones currently requires a ground station and an operation team. And at the landing airport, the same ground station is needed, and an operations team is also needed.

[0031] The current unmanned aerial vehicle system is a flight system composed of unmanned aerial vehicles and ground stations, and is jointly used by multiple professional operators. Usually take off at the airport, work in the air after take off, and then land at the airport. With such a composition and use method, it is a typical configuration and use method of UAVs at present, and can be called a principle UAV.

[0032] The cost of purchasing and using principle drones is relatively high, and the technical thresh...

Embodiment 2

[0042] Examples of new aerial operations using UAVs for aerial surveying and mapping and agricultural and forestry observations.

[0043] 1. Aerial surveying and mapping

[0044]The UAV performs aerial surveying and mapping at an altitude of 2600m in an area 400km away from the departure airport, and the estimated flight time is 10h. The survey area is about 10,000 km 2 .

[0045] The principle type UAV is used for aerial surveying and mapping operations. It takes off at the local field, flies to the operating airspace, and then returns to the original airport for landing. The ground station is arranged in the airport, and the operators are also arranged in a centralized manner. The changes in the new mode of operation are more obvious:

[0046] At the airport, the general aviation company is responsible for the pre-flight maintenance preparation of the UAV, and uses the airport general link command to take off.

[0047] In the operation area, rent a mobile operation moni...

Abstract

The invention discloses a flight control method for station and aircraft separation of an unmanned aerial vehicle system. By the method, a configuration mode of the unmanned aerial vehicle is reconstructed, an onboard detector is configured by proposing an automatic deviation measurement and correction technology, so that airport data chain and a ground station are cut, and a novel formation scheme of an onboard and ground system is proposed. Separated application of the station and the aircraft of the unmanned aerial vehicle system is supported, operation teams are built according to tasks, the construction cost and the operation cost of an air line are reduced, and dispatching of an airport and the air line is facilitated. The invention provides a novel configuration design and application method of an industrial unmanned aerial vehicle, low-cost configuration and application are achieved, the method is particularly and suitably used for aviation transportation, a solution scheme ofcost reduction and flexible application is also provided for operation of an unmanned aerial vehicle in air, a new path is provided for transformation development of an existing navigation enterprise,and new kinetic energy is provided for the unmanned aerial vehicle to achieve industrial development.

Description

technical field [0001] The invention relates to the field of aviation navigation and control, in particular to the application of flight control of aircraft and the application of communication technology for long-distance and low-altitude flight of aircraft. technical background [0002] Fixed-wing UAVs are often disturbed by crosswinds during approach and glide landing, take-off and landing taxiing. Due to the time lag in the deviation correction control response of the airborne navigation and flight control system, which is called the navigation and flight control computer system, it causes deviation from the scheduled taxiway. Centerline or flight path, severe cases can lead to a large lateral deviation and skid off the runway. At present, the technical measures to correct sideways mainly adopt the auxiliary control of manual remote control command to correct. The more commonly used remote control method is discrete quantized remote adjustment and deviation correction. ...
