Tasteful rescue and disaster relief drones. Combined Atlas (2 photos) UAVs first appeared in the 20s of the 20th century, in 1914 the First World War was in full swing, the British generals Cadell and Pichell, to the British Military Aeronautical and Astronautical Society put forward a proposal: to develop a kind of small aircraft that does not need to be piloted, but controlled by radio, so that it can fly over a certain target area of the enemy, and drop bombs mounted on small planes in advance. This bold idea was immediately appreciated by Sir Day Henderson, then president of the British Military Aviation Society. Professor Lowe led a team of people to develop it. UAVs were used as training target aircraft at the time. is a term used in many countries to describe the latest generation of unmanned aircraft. Literally, this term can describe cruise missiles developed from kites, radio-piloted aircraft, to V-1 missiles, but in military terminology it is limited to reusable heavier-than-air vehicles. Drone R&D history

In the 40s of the 20th century, unmanned target aircraft were used to train anti-aircraft gunners in World War II.

In 1945, after World War II, redundant or decommissioned aircraft were converted into special research or target aircraft, which became a precedent for the use of UAVs in modern times. With the advancement of electronic technology, drones have begun to show their flexibility and importance in the role of reconnaissance missions.

In the Vietnam War, the Gulf War and even NATO's air raids on Yugoslavia from 55 to 74 in the 20th century, UAVs were frequently used to carry out military missions.

In 1982, Israel Aerospace Industries (IAI) pioneered military missions with drones in other roles. During Operation Peace of Galilee (Lebanon War), the Scout UAV UAV UAS used to play an important combat role in the service of the Israeli Army and the Israeli Air Force. The IDF mainly uses drones for reconnaissance, intelligence gathering, tracking and communications.

During the 1991 Desert Storm operation, the U.S. military launched a small unmanned aerial vehicle (UAV) specially designed to deceive the radar system as a decoy, and this decoy has also become the target of imitation by other countries.

In March 1996, NASA developed two test aircraft: the X-36 experimental tailless unmanned fighter. The aircraft is 5.7 meters long and weighs 88 kilograms, which is 28% the size of a regular fighter jet. The aircraft uses a split aileron and steering thrust system that is more flexible than a conventional fighter. The horizontal and vertical tail reduces both weight and tensile forces, as well as a reduced radar reflection cross-section. The ideal tasks that the unmanned fighter will perform are to suppress enemy air defense, interdiction, combat damage assessment, theater missile defense, and ultra-high-altitude attacks, and are particularly suitable for carrying out tasks in politically sensitive areas.

Before the late 20th century, they were just a little smaller than full-size remote-piloted aircraft. The U.S. military's interest in these types of vehicles is growing because they offer low-cost, mission-resilient fighting machines that can be used without the risk of crew death.

In the 90s of the 20th century, after the Gulf War, UAVs began to develop rapidly and be widely used. The U.S. military once purchased and homemade Pioneer drones as a reliable system in the second and third Gulf Wars against Iraq.

After the 90s of the 20th century, Western countries fully realized the role of UAVs in warfare, and competed to apply high and new technologies to the research and development of UAVs: new airfoils and lightweight materials greatly increased the endurance of UAVs; advanced signal processing and communication technology were used to improve the image transmission speed and digital transmission speed of UAVs; advanced autopilots made UAVs no longer need land-based TV screens to navigate, but flew to the hovering point according to the program, changed the altitude and flew to the next target.

The domestic UAV market has been developing for nearly 30 years, gradually expanding from the initial military field to the consumer field. In the past two years, drone companies, the number of financing, the number of pilots and the use of products have increased significantly, and even exponential growth, and the regulatory system has been further improved. In the next five years, the civil drone industry will continue to maintain a rapid development trend, and the sales market size of China's civil drone products will reach 26.5 billion yuan in 2020 (data source: Yuchen.com). According to the British "Daily Mail" report on April 4, the U.S. military recently approved four companies to develop a drone plan to work in a group collaboration mode, so as to replace humans to carry out dangerous tasks, and hope to greatly reduce the cost of using multi-functional fighters. UAVs will become the key direction of Changzhou's "intelligent manufacturing".

Drones will dramatically change urban and rural life

If you live in rural areas, you will be amazed at the outstanding performance of drones in improving the transportation capacity of remote areas and improving agricultural production efficiency. If you are a member of the city, you will also be pleasantly surprised to see the extraordinary role of drones in solving the problem of turtle speed logistics and urban planning and construction management. In this era when technology is devouring the world, drones are seeping into people's daily lives like air, in crowded big cities, and in the countryside at the other end.

In rural areas, the moment a drone flies into a field means that the way agricultural production is being transformed again. Because drones are providing a modern, high-efficiency, low-cost plant protection method for agriculture, helping farmers gradually improve their agricultural operations. In traditional agricultural production, farmers apply fertilizer, spray pesticides, and prevent pests and diseases based on experience, and in the process of operation, they must be personally involved in each piece of land and crops. This extensive mode of operation, high intensity, low efficiency, and UAV will be an important means of transformation from heavy manual labor, high cost, low efficiency to liberate productivity, low cost, high efficiency, UAV technology in-depth and use, will make the existing farmland farming more efficient, more resource-saving and environmentally friendly.

In many remote mountainous areas, poor roads cut farmers off at certain times of the year, and we have no reliable way to supply them with medicinal herbs, collect supplies of critical supplies, and bring their produce to market to generate sustainable income.

Imagine that you are in a rescue area in Africa and a patient needs an urgent blood transfusion, what would you do? Ask for help on your mobile phone, and you will be able to respond to your request for help soon, but it may take many days for the blood to arrive because the roads are so poor. Therefore, in remote and underdeveloped rural areas, another important application of drones is to provide us with a way to quickly traverse poor roads and transport light and small materials.

At this end of the social spectrum, in remote and underserved areas, drones give us a shortcut through bad roads. In the city, drones can be used as a new means of transportation to make our city life more convenient. In today's world, half of the world's population lives in cities, 500 million people live in megacities, and traffic congestion is a huge problem in large cities and megacities. It is used to transport small, light, urgent things and provides a completely modern solution to the problem of logistics slowdowns caused by traffic jams.

In cities that are constantly undergoing rapid changes, in addition to providing logistics solutions, drones can also provide basic geographic information and law enforcement forensics for urban planning, construction and management, such as urban road and bridge construction, traffic patrol, public security monitoring, urban law enforcement, etc. A typical application case: when we are carrying out urban planning, we often need more detailed urban land use information, if manual survey, the workload is very huge, and these information about urban residential land, road traffic, public buildings and other aspects can be clearly interpreted and extracted from UAV aerial images.

From powering modern villages to powering smart cities, drones will be there wherever aerial solutions are needed. UAVs will be used in a wider range of fields.
