Abstract

PURPOSE:To secure a flight control for such a robot plane that is high reliability plus high performance and reduce the cost of development by providing a drone computer, emitting a command almost equivalent to a pilot, and a radio-controlling actuator operating a rod or cable with a command of the computer, respectively. CONSTITUTION:A robot plane flight control is one that has added a drone computer 6 and a radio-controlling actuator 7 to the existing flight control such as a body motion dynamics 1, an actuator 2, a sensor 3, a flight control 4, a rod-cable 5 and so on. A flight pattern or the like flying a robot plane is stored in the drone computer 6 which has two functions, one emitting a command making an airframe perform its up, down, turning, speed increase and decrease, etc., to the radio-controlling actuator 7, and the other transmitting a signal for switching the existing auto pilot in order to keep the airframe technical data when it has come to the desired airframe technical data, to the existing flight control 4.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a flight control device for an unmanned aircraft.

[Conventional technology]

Conventionally, for example, if an aircraft is operated as a manned aircraft as shown in Figure 2, or if a used aircraft is modified and used as an unmanned aircraft, it can be used as an unmanned aircraft as shown in Figure 3. The existing flight control device was removed and a new sensor, which is not shown with a double frame, was installed. (For human aircraft: Equipped with normal flight control equipment such as J-computer and unmanned aircraft actuators, and redesigned including the control part of the unmanned aircraft.When using this type of aircraft, improvements have been made over many years. Since the existing 7F flight control system, which is trusted to be safe, is not used, it is necessary to develop a completely new flight control system, including the flight control system, which increases development risks and shortens the development period.

[Problem to be solved by the invention]

There were the following issues that needed to be solved with conventional unmanned aircraft control systems.

That is, the flight control system of an aircraft needs to have a function for stably flying the aircraft, whether it is a one-person aircraft or an unmanned aircraft. In recent years, the performance of aircraft has been increasing, and the function for safely flying the aircraft is increasing stability by using the aircraft's motion information to perform Phytobank control calculations and giving commands to the necessary control surfaces. given by the device. There is a problem in that if such existing control devices cannot be used as is, there will be a large risk to flight safety. In view of these problems, the present invention uses the existing aircraft motion function or motorcycle loft function to simply add a new unmanned aircraft control function, and the newly added computer can perform various switching operations as if it were a pilot. The purpose is to provide an unmanned aircraft control system that issues flight commands to existing systems, including switching operations.

[Means to solve the problem]

The present invention provides a series of control devices including lofts or cables, actuators, airframe motion dynamics, sensors, and flight control devices that operate when the pilot operates a control frame to control the airplane. The operation of an unmanned aircraft characterized by being equipped with an unmanned aircraft operating computer that issues equivalent commands, and an unmanned actuator that operates the loft or cable according to the instructions of the unmanned aircraft operating computer. Device.

[Effect]

Since the present invention is constructed as shown in letter L, the following effects are achieved.

For example, a case of automatic turning flight will be explained. First, the unmanned aircraft computer performs the necessary calculations to change the attitude of the aircraft, and the unmanned aircraft actuator moves the loft or cable to steer the aircraft. Therefore, by switching on the existing autopilot and maintaining the aircraft attitude when the desired aircraft attitude is reached, it becomes possible to continue the automatic turning movement.

(Example) A control device for an unmanned aircraft according to an example of the present invention will be explained with reference to FIG.

The unmanned aircraft control system according to this embodiment is based on the existing flight control system Aircraft Dynamics
Characteristics of the airplane's movement relative to the movement of the control surface or throttle) l, actuator 2° sensor 3. Flight control device 4
．． An unmanned aircraft computer 6 and an unmanned aircraft actuator 7 are added to the loft, cable 5, etc. shown in double frames.

The unmanned aircraft computer 6 stores flight patterns and the like for flying the unmanned aircraft, and sends commands for ascending, descending, turning, speeding up, decelerating, etc. the aircraft to the unmanned aircraft actuator 6. function and the desired aircraft speed (altitude, speed.

It has an I function that sends a signal to the existing flight control device 4 to turn on the existing autopilot in order to maintain the aircraft specifications when the aircraft reaches a certain attitude angle (attitude angle, etc.). Furthermore, this type of unmanned aircraft does not necessarily only fly in a predetermined flight pattern, but may also be guided by an actual pilot by radio from a flight control device on the ground. At this time, the unmanned aircraft computer 6 is simply a pylon on the ground]
This embodiment is particularly advantageous in terms of simplification, since only the commands from .

As described above, according to this embodiment, by simply adding an unmanned aircraft computer and an unmanned aircraft actuator to an existing flight control device that is stably used and highly reliable,
There is an advantage in that a control device for an unmanned aircraft can be obtained that can perform eleven operations such as descending, turning, accelerating, and decelerating.

(Effect of the invention) Ki-ni 11IH 1. Since it is configured as shown below, the following effects are explained below.

In other words, with conventional control devices, it was necessary to develop a completely new flight control device that also included unmanned functions, whereas the present invention uses the conventional device as is and adds only the functions necessary for °C unmanned flight. By doing so, the product reliability and high performance unmanned aircraft control system will be (¥t), so the development cost will be reduced to 2M.
5. Safety risks can be significantly reduced.
