What is a fixed wing aircraft
A fixed-wing aircraft is an aircraft that relies on fixed wings to generate lift. It is an important tool in modern air transportation and military activities. Unlike rotary-wing aircraft (such as helicopters), the wings of fixed-wing aircraft are fixed, and engines provide thrust to accelerate the aircraft on the runway and take off. This article will introduce in detail the definition, classification, working principles and hot topics of fixed-wing aircraft.
1. Definition and classification of fixed-wing aircraft
A fixed-wing aircraft refers to an aircraft whose wings are fixed to both sides of the fuselage, which is driven by an engine to generate thrust and uses the lift of the wings to fly. Fixed-wing aircraft can be divided into the following categories based on their purpose and design features:
| Classification | Features | Typical representative |
|---|---|---|
| Civilian airliner | Used for commercial passenger transportation, with large passenger capacity and long range | Boeing 737, Airbus A320 |
| military fighter | High mobility, equipped with weapon systems | F-22 Raptor, J-20 |
| general aviation aircraft | For private aviation, agriculture, rescue, etc. | Cessna 172, Beechcraft King Air |
| drone | Unmanned driving, used for reconnaissance, logistics, etc. | MQ-9 Reaper, DJI drone |
2. Working principle of fixed-wing aircraft
The flight of a fixed-wing aircraft relies on the balance of four basic forces: lift, gravity, thrust, and drag. Here's a brief explanation of how it works:
| force | function | Production method |
|---|---|---|
| Lift | make the plane rise | The difference in air pressure between the upper and lower surfaces of the wing |
| Gravity | bring the plane down | Earth's gravity |
| Thrust | make the plane move forward | engine or propeller |
| resistance | Impeding the plane's progress | Air friction and shape resistance |
