With the continuous development of science and technology, radio control aircraft (radio control system) has become one of the indispensable weapons in modern war. It can control the aircraft by transmitting and receiving signals.
1. Principles of radio control of aircraft
The principle of radio controlled aircraft is to use radio waves to transmit and receive signals so that the aircraft can be controlled. When someone is near or approaching the target, the pilot can sense and react to this information through an EEG machine or a microphone. Set a “counter” program on the computer, then input the corresponding parameters according to the system output, the system will automatically adjust the flight attitude or change the flight speed. In addition, control can be given to other drivers, such as Monitor. Composition: The radio control system is composed of sensors, electronic circuit boards, analog devices and controllers. The sensors mainly include temperature sensor, pressure sensor, altimeter, gyroscope and acceleration sensor.
2: Composition
The main components of radio control aircraft are flight control system, airborne communication system and communication equipment. The flight control system is the central nervous system of the helicopter, which is responsible for adjusting the output power of the engine, directing the pilot to operate the navigation system in the cockpit and improving the stability of the helicopter in the air. The airborne communication system provides the means of information exchange between the helicopter and the ground personnel. Communications equipment is used to receive signals from ground radar, radio and so on and convert them into a signal source that can be transmitted to a helicopter.
3: Application
There are three main applications of radio control system in aircraft: flight control, communication and navigation. Among them, flight control is one of the important components of aircraft. An airplane needs a certain speed to maintain altitude and stability during takeoff; During the flight, the aircraft will be affected by wind and other factors, so it is necessary to effectively control the flight. In order to achieve these requirements, radio control systems must be used. On the other hand, when the plane encounters an obstacle or an emergency, the pilot can send an alert signal through the radio system so that other crew members can take action. In addition, wireless control systems can also be used for communication. When the plane is connected to equipment on the ground or in the air, the pilot can issue commands to others via a wireless control system to obtain relevant information. Finally, radio control systems can also be used for navigation.
However, due to various factors affecting the transmission of radio signals, it is necessary to pay attention to these factors when using radio-controlled aircraft. It is hoped that this article will help you better understand the principle and composition of radio controlled aircraft.
