Description

An electric flying car

Technical Field

The invention relates to an electric aircraft based on foldable wings, in particular to an electric flying car, and belongs to the field of aviation and automobile technology.

Background technique

With the advancement of science and technology, multi-habitat transportation has become a development trend. Flying cars can travel on the ground and fly in the air. They have become a new type of transportation that can solve the problem of urban traffic congestion and flexibly transport people or goods. Many companies and institutions at home and abroad are carrying out research and development and engineering application of flying cars. Flying cars can be divided into two types according to different take-off and landing methods: vertical take-off and landing and taxiing take-off and landing. Most vertical take-off and landing flying cars are similar to multi-rotor drones. They are flexible in take-off and landing, and the flight control is simple to operate. However, they have slow flight speeds and high energy consumption during cruising. In addition, multi-rotors are not easy to place when the car is on land, which affects the ground driving function and makes it difficult for it to have the same ground driving stability and controllability as ordinary cars. Taxiing take-off and landing flying cars need a certain length of road taxiing to complete take-off. The cruising flight has low energy consumption, but the car wings take up a lot of space after folding. In addition, most flying cars are medium- and high-altitude flying cars, flying at hundreds of meters or kilometers. Once a malfunction occurs, it may lead to catastrophic consequences, so it requires high driving skills and psychological quality of the user. In addition, people generally have concerns about high-altitude flying, which makes it difficult to promote and apply flying cars. Moreover, the higher the flying altitude of the flying car, the greater the fuel or electricity consumption, and the worse the economy.

Ground effect is a wonderful aerodynamic phenomenon, that is, when a moving object is very close to the ground (or water surface), the pressure difference between the upper and lower surfaces of the object increases, and the lift of the object will increase sharply, so that it can fly close to the ground or the sea. By combining ground effect with cars and using new energy, an electric ground effect flying car was invented, which can not only drive on the ground road, but also achieve ultra-low altitude flight below ten meters. It has high safety, good economy, flexible and convenient use, and has a very broad application prospect.
