What is the principle of model aircraft?
An aircraft model (aerospace model) is a reduced or simplified version that simulates a real aircraft. Its flight principle is similar to that of a real aircraft, but its scale and complexity are lower. In recent years, with the development of science and technology, model aircraft has gradually become a popular hobby and competitive event. The following are the hot topics and content on the Internet in the past 10 days, combined with a detailed analysis of the principles of model aircraft.
1. Basic principles of model aircraft
The flight of model aircraft mainly relies on the synergy of aerodynamics, propulsion system and control system. The following are the core principles of model aircraft flying:
| Principle | Description |
|---|---|
| Lift | Through the airfoil design of the wing, Bernoulli's principle is used to generate lift, allowing the aircraft model to leave the ground. |
| Thrust | An electric motor or internal combustion engine drives a propeller or jet to provide forward motion. |
| Gravity | The weight of the aircraft model needs to be balanced by lift, otherwise it will fall. |
| resistance | The obstruction of the air to the movement of the aircraft model needs to be overcome by optimizing the design and power system. |
2. Classification of model aircraft
According to different power systems and uses, model aircraft can be divided into the following categories:
| Type | Features |
|---|---|
| Fixed wing model aircraft | Lift is generated through the wings, suitable for high-speed flight and long-distance flight. |
| Rotor model aircraft | Such as helicopters or multi-rotor drones, which generate lift through rotating rotors and are suitable for hovering and vertical take-off and landing. |
| glider | Flying by relying on air currents and terrain lift, usually without power or power assistance. |
| Jet model aircraft | Simulates a real jet aircraft with strong power and suitable for high-speed flight. |
3. Control system of model aircraft
Modern model aircraft are usually equipped with advanced remote control systems. The following are common control methods:
| Control method | Function |
|---|---|
| remote control | Control the flight attitude, speed and direction of the aircraft model through radio signals. |
| flight control system | Built-in sensors and computers automatically stabilize the flight status of the model aircraft. |
| GPS navigation | Achieve autonomous flight and fixed-point hovering, often used in drones. |
| FPV (first person perspective) | Real-time perspective control is achieved through the camera and display. |
4. Hot model aircraft topics in the past 10 days
