A few months ago, German carmaker Porsche and Boeing announced they would work together to build a flying car, foreign media reported. Recently, a patent application filed by Porsche company has appeared on the Internet, which shows the possible appearance of such a flying car. (photo source: carscoops. Com) the patent was submitted by Porsche to the U.S. patent and Trademark Office on July 2, 2019, and officially announced on January 9, 2020, describing a flying car capable of vertical takeoff and landing (VTOL), including a series of basic drawings. (photo source: U.S. patent and Trademark Office) the flying car has four large propellers, two of which are facing down, which can provide up (or down) thrust. At the same time, there is a group of larger fans at the rear, which can also point down, so that the flying car can leave the ground, and then rotate 90 degrees, so that the VTOL flying car can move forward, including one that can hold two propellers People's cabin. The patent also said: "the flying car is not equipped with a rotor that can move freely, but uses multiple duct fans of different sizes, which may be used to drive the flying car, just like the fans used in hovercraft or fan boats outside the aerospace industry." According to the patent, the flying car is equipped with wings, heat conducting elements and heat conducting elements connected to the battery, so that the heat generated by the battery can spread to the wings. The advantages of the flying car include reduced complexity and reduced weight. In addition, the flying car is equipped with folding or even optional folding wings, as well as a battery system with fast charging speed, which can provide energy for the vertical takeoff and landing and horizontal flight of the flying car, and the flying car can also be temporarily charged when it is still. (photo source: U.S. patent and Trademark Office) finally, in addition to giving priority to fully automatic flight of the flying car, it will also consider allowing a qualified human pilot to manually control the flying car, that is, to have the greatest flexibility in operation. According to the memorandum of understanding signed by Porsche and Boeing, the two companies will "explore the high-end urban air traffic market and extend urban traffic to the sky area." The two companies have confirmed that they are developing an electric vertical takeoff and landing tool, but they only use it as a concept, and it is not sure whether the concept of the vertical takeoff and landing flying car described in the patent is this concept.
