I have shared with you the development history of multi-rotor UAVs before, so about another main model of UAVs, Fixed Wing UAV, today I will also take you to understand its brief development history.

First of all, let's first understand what a Fixed Wing UAV is. The so-called Fixed Wing UAV refers to a type of unmanned aerial vehicle with fixed wings whose sweep angle at the outer end of the wing can be adjusted automatically or manually with the speed. It consists of five parts: airframe structure, avionics system, power system, takeoff and landing system, and ground control station system.

The birth of the Fixed Wing UAV originated from the fact that on December 17, 1903, the Wright Brothers of the United States purchased and tested a biplane—the Aviator. The first powered aircraft capable of free flight and controllable. therefore. December 17, 1903 also became the birthday of the airplane. In the early days of aircraft development and technological development, both the engine power and weight of biplanes were very low and heavy, and due to the limited materials at that time, the construction materials of the aircraft were based on catalogs and fabrics. Mainly. In order to enable the aircraft to generate huge lift at low speeds, the researchers designed the wing area to be large to ensure that the aircraft can take off smoothly at low speeds. However, due to the in-depth development of research, the flight speed of the aircraft is also continuously optimized and improved. At this time, the huge wings become an obstacle that delays the flight speed of the aircraft. In order to break through the flight speed, engineers began using high-strength aluminum alloy as the raw material for the wing. Aluminum alloy is light in weight and has a high bearing capacity. In the following decades, it has been one of the main materials for aircraft manufacturing. Since then, the double wing has gradually been replaced by a single wing. The era of single-wing propeller aircraft dominated the 1930s and 1940s, and after the 1940s, jet aircraft came to prominence. Jet aircraft rely on the recoil effect of gas generated during fuel combustion to eject backward at high speeds to make the aircraft fly forward, which can enable the aircraft to obtain greater thrust and fly faster. However, the cost of using jet aircraft is also high, so it a major limitation.

For Fixed Wing UAV, no matter in any field, it has extremely important value and can meet various needs. Improving self-control levels for Fixed Wing UAV and adapting to the future market will also be a problem for major engineers to continuously improve and optimize.
