Embodiment Construction

[0024] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0025] figure 1 Among them, including nose propeller 1, nose engine 2, fuselage 3, wing propeller 4, wing suspension engine 5, wing 6, horizontal tail 7, vertical tail 8, etc.

[0026] Such as figure 1 As shown, it is a rappelling unmanned aerial vehicle. The body adopts a propeller pull-in conventional layout, including a nose propeller 1, a fuselage 3, a wing 6 and an empennage. The nose propeller 1 is connected to the nose engine 2, and the empennage Including horizontal empennage 7 and vertical empennage 8. In the present invention, a wing hanger engine 5 is symmetrically fixed respectively below the two wings 6, and the front of each wing hanger engine 5 is respectively connected with wing propellers 4, thereby forming three propeller pull-in forms.

[0027] Nose engine 2 is mainly used for cruising flight, and two wing suspension en...

Abstract

The invention relates to a vertical touchdown type unmanned aerial vehicle and a control method thereof. The unmanned aerial vehicle comprises a nose propeller, a fuselage, wings and a tail, wherein the nose propeller is connected to a nose engine; wing hanging engines are respectively fixed below the two wings symmetrically; the front part of each wing hanging engine is connected with a wing propeller. The control method for the rappelling unmanned aerial vehicle comprises the following steps: (1) acquiring specific coordinate information of a vertical touchdown place; (2) dividing a flight path into four stages of cruise flight, diving acceleration, climbing and rising, and vertical ascending and falling based on the flight state information of an aircraft; and (3) designing a control loop which takes two parameters of the flight path and flight attitude as variables, correcting the flight path deviation caused by airflow disturbance or control error in time, outputting a pneumatic control surface deviation control amount and pull control amounts of each engine, and controlling the aircraft to finish the overall vertical touchdown process. According to the vertical touchdown type unmanned aerial vehicle and the control method thereof, the vertical touchdown can be performed by using an unmanned aerial vehicle, and the using performance and the working capability of the aircraft are improved.

Description

technical field [0001] The invention relates to an unmanned flying platform, in particular to a rappelling unmanned aerial vehicle and a control method thereof, belonging to the technical field of aeronautical engineering. Background technique [0002] Vertical landing (referred to as "rappel") technology refers to the technology that the aircraft can land without taxiing. Usually, the landing method of conventional layout aircraft is to roll and land, so a runway is required. The rappelling mainly means that the aircraft can rappel in situ without using a runway, and there is no requirement for the runway, so it has always been the goal pursued by aviation professionals. [0003] The rappelling technology of conventional layout aircraft began in the 1950s and 1960s after World War II. People worried that nuclear war would damage the airport runway and conventional aircraft could not be dispatched, thus giving birth to this aviation technology. The existing rappelling tech...
