Description

[0001] This application relates to the field of aircraft technology, and in particular to an aircraft power-saving control method, control system, flight equipment and storage medium. Background Technology

[0002] Existing aircraft technologies mainly categorize them into fixed-wing aircraft, multi-rotor aircraft, and compound-wing aircraft. In practical applications, fixed-wing and compound-wing aircraft each have their advantages and disadvantages. Fixed-wing aircraft are characterized by long endurance and high-altitude flight, and are widely used in surveying, geology, petroleum, agriculture, and forestry. Compound-wing aircraft, on the other hand, can take off and land vertically and hover, making them primarily suitable for low-altitude, low-speed operations requiring vertical takeoff and landing and hovering.

[0003] While existing compound-wing aircraft possess both vertical takeoff and landing (VTOL) and fixed-wing flight modes, the transition between modes (from cruise to VTOL) results in excessive energy consumption due to their longer flight range, thus failing to achieve energy conservation.

[0025] The term "compound wing aircraft" is defined as an air transport system of any size that has at least one propeller as its propulsion source. The term "compound wing aircraft" can include both "manned" and "unmanned" air transport systems. A manned compound wing aircraft can refer to an air transport system carrying one or more human passengers, none of whom have control over the compound wing aircraft.

An unmanned compound wing aircraft can refer to an air transport system that does not carry any human passengers and flies autonomously or is remotely controlled by someone at a distance.

[0026] The first embodiment of this application is described below with reference to the accompanying drawings. As shown in FIG1, the first embodiment of this application discloses an aircraft power-saving control method. The aircraft includes at least one tail thrust motor. The aircraft power-saving control method includes:

[0027] The flight mode of the aircraft is acquired in real time, and the tail thrust control strategy of the tail thrust motor 20 is activated according to the flight mode to achieve active speed reduction of the aircraft and shorten the flight range.

[0028] Aircraft often employ distributed electric propulsion, and their flight modes include vertical takeoff and landing mode, cruise mode, and switching mode. In the embodiments of this application, the aircraft uses multiple rotor motors and at least one tail thrust motor. The rotor motors can be, for example, 8, 10, or more, and the tail thrust motors can be, for example, 2, 3, or more. The rotor motors are used to provide lift, yaw control, roll, and pitch control in multi-rotor mode, while the tail thrust motors are used to control airspeed and altitude in fixed-wing mode.

[0029] In this embodiment, as shown in Figures 3 and 4, there are two tail thrust motors 20. Of course, in other embodiments, there may be one, three, or four tail thrust motors 20; this application does not impose specific limitations on this. Specifically, the tail thrust control strategy for activating the tail thrust motors 20 in flight mode includes: if it is determined that the flight mode has entered a transition mode, the aircraft activates the tail thrust control strategy for the tail thrust motors 20. This control strategy can be manually activated by ground control station personnel, or it can be activated automatically by the system's artificial intelligence. The transition mode can be a forward transition mode or a reverse transition mode. A forward transition mode refers to the process of the aircraft transitioning from vertical takeoff and landing mode to cruise mode, while a reverse transition mode refers to the process of cruise mode transitioning to vertical takeoff and landing mode. In this embodiment, the aircraft's transition mode specifically refers to the process of transitioning from cruise mode to vertical takeoff and landing mode.

[0030] Specifically, the tail thrust control strategy for the tail thrust motor 20 includes controlling the direction of the tail thrust motor 20. When there is only one tail thrust motor 20, it initially rotates forward. Upon entering the transition mode, the tail thrust motor 20 then reverses direction, thus achieving active speed reduction. When there are two tail thrust motors 20, one rotates forward while the other rotates in the opposite direction, also achieving active speed reduction. Activating the tail thrust control strategy for the tail thrust motor 20 can, on the one hand, actively reduce speed to shorten the flight range during the transition mode, and on the other hand, achieve energy saving.

[0031] In some embodiments, there are three tail thrust motors 20. Three tail thrust motors 20 increase the redundancy of the control vector. The flight speed control channel required by the system is handled by three tail thrust motors 20, which can reduce the power output burden of each tail thrust motor 20 and also cope with the situation where one of the motors may fail.

[0032] Specifically, in this embodiment, the tail thrust control strategy includes: adjusting the power output weight ratio of the aircraft control channel according to the aircraft's flight mode.

[0033] Specifically, the aircraft control channels include at least the aircraft yaw control channel, the aircraft roll control channel, the aircraft pitch control channel, and the aircraft flight speed control channel. Adjusting the power output weighting ratio of the aircraft control channels specifically includes adjusting the power output weighting ratio of the aircraft in the flight speed control channel.

[0034] By reducing the power output weight ratio on a certain control channel of the aircraft, the system allocates the remaining power output to the aircraft roll control channel, pitch control channel, and yaw control channel, etc., to prevent power shortage due to motor failure, thereby improving the aircraft's handling performance and ensuring flight safety. In one embodiment, the aircraft outputs no power at all on the yaw control channel.

[0035] The tail thrust control strategy for activating the tail thrust motor includes controlling the rotation direction of at least one tail thrust motor to reduce the aircraft's flight speed, thereby shortening the transition flight distance after the aircraft enters the transition mode.

[0036] The second embodiment of this application discloses an aircraft power-saving control system, the aircraft including at least one tail thrust motor. The aircraft also includes: a flight mode detection module for determining the current flight mode of the aircraft; a power distribution module for adjusting the power output weight ratio on each control channel of the aircraft; and a tail thrust motor control module for adjusting the direction of at least one tail thrust motor according to the current flight mode.

[0037] The third embodiment of this application discloses a flight device, including the power-saving control system of the above embodiments, at least one processor, and a memory communicatively connected to the at least one processor, wherein the memory is executed by the at least one processor to enable the at least one processor to execute the power-saving control method of the above embodiments.
