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] like 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 engin...

Abstract

The invention relates to a rappelling unmanned aerial vehicle and a control method thereof. The rappelling UAV includes a nose propeller, a fuselage, a wing and an empennage. The nose propeller is connected to the nose engine, and a wing hanger engine is symmetrically fixed under the two wings. Each wing hanger engine The front is respectively connected with winged propellers. A control method for rappelling an unmanned aerial vehicle, comprising the following steps: (1) Obtaining specific coordinate information of a rappelling location; (2) Based on the flight state information of the aircraft, dividing the flight path into cruising flight, dive acceleration, climbing head-up, vertical There are four stages of ascent and descent; (3) Design a control loop with the two parameters of flight path and flight attitude as variables, and immediately correct the trajectory deviation caused by airflow disturbance or control error, and output the deflection control of the aerodynamic rudder surface The amount and the pulling force control amount of each engine control the aircraft to complete the entire rappelling process. The invention can make the unmanned aerial vehicle rappel and improve the use performance and working ability of the aircraft.

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...
