经常出现在影视剧中的飞行汽车诱惑力许多小车发烧友的关心，各大汽车企业也接连不断的发布过一些航空概念跑车，殊不知这种车子在日常生活中却基本上从没出現过。在电脑上能够 帮助别人进行工作中，手机上能够 陪人闲聊，电机能够 驱动器小车飞快行车的“高宽比智能化系统”的科技时代，保持小车航空没办法吗？
在这里一环节中人们并未迈入这三级文明行为级别中的新手入门，简单点来说人们的高新科技水准现在归属于初始阶段，为大行星文明行为。而飞行汽车在影视剧中大多数为反重力技术性，车子能够 安安稳稳的飘浮半空中不会受到一切约束力，其耗能能够 保证十分之低乃至有無限电力能源的特性，定义参照下面的图。
The attractiveness of flying cars that often appear in film and television dramas is the concern of many car enthusiasts. Major car companies have also released a number of aviation concept sports cars one after another. I do n’t know that such cars have basically never appeared in daily life. In the era of science and technology that can help others to work on the phone, can chat with people on the phone, and drive the car to "rapidly move" in the "aspect ratio intelligent system", is there no way to keep the car aviation?
Correct answer: The difficulty factor is very high, so high that it has no practical significance for popularization!
Many people think that in the age of science and technology, there is no idea that they cannot be maintained, but they do not know but ignore the hierarchical classification norms of the technical level of civilized behavior. Refer to the Kaldashev level norm.
I: This civilized behavior (history of human development) is the host of the planetary power energy, which can be the comprehensiveness of all global power energy of the God of Shura.
II: This civilized behavior can collect the power energy of all planetary system software.
III: This civilized behavior can use the electric energy of solar system software for its common use.
In this link, people have not stepped into the novice entry of these three levels of civilized behavior. To put it simply, the high-tech level of people now belongs to the initial stage, which is the behavior of large planet civilization. Most flying cars are anti-gravity technology in film and television dramas. The car can float in the air safely without being subject to all constraints. Its energy consumption can be guaranteed to be very low and even has the characteristics of infinite electric energy. For definition, refer to the following Illustration.
However, at the current high-tech level, it is impossible to maintain anti-gravity, so flying cars can only have two shapes: fixed-wing (telescopic wing) flying cars, rotary-wing models or helicopter flying cars. The characteristic is the application of a star piston engine.
The piston engine is the same as the piston engine used in trolleys, and both are internal combustion heat engines. The difference is that in-line or horizontally opposed diesel engines are used for trolleys. The characteristic of the equipment is "lay flat", which is accepted and enlarged according to the transmission. The torque output of the diesel engine maintains the transmission system. The diesel engine used in the airport has a star structure. Its characteristics are that the engine crankshaft is located in the middle, and the piston rod crankshaft is tightly arranged around the engine crankshaft.
The advantages of this type of diesel engine are simple structure, light weight, high torque and high weight-to-weight ratio; however, this type of equipment is also a relatively prominent defect, which actually has two points.
1: The diesel engine is a pillar structure, which occupies a very large space. For a car, this type of equipment is not suitable for application. Because it will block the view of the front gear, in addition, the star engine is only used to maintain the rear drive. The rear axle of the car can only output the driving force according to the transmission and the rotating shaft. It is unknown that with the large-capacity vertical transmission, the quality of weapons and equipment of this type of car will be very high. The mass is high and the horsepower required for all normal and safe driving will be quite large, so the horsepower required for takeoff is even greater. For star engines to maintain high power output, they must run at low gears and high speeds. High speeds will cause very serious problems. The first is that high speeds will increase the damage of diesel engines and reduce the service life, followed by high speeds. Extreme noise and vibration and the vibration of the star engine are already significant, but this is not the most critical problem.
2: The most critical problem is fuel consumption. Everyone knows that the higher the speed of internal combustion vehicles, the higher the fuel consumption. The higher the speed ratio, the higher the negative pressure of the diesel engine breathing; the gas-to-fuel ratio of a diesel engine is If it is fixed, the larger the intake air supply, the ignition advance angle will undoubtedly increase at the same time. The average family-installed scooter is driven at a low speed ratio of an average of 2000 to 3000 rpm, and the average fuel consumption of A / B-class vehicles will be around 10L / 100km; if the design of safe driving is radical, the time is 4000 to 6000 The speed is faster than driving, and the fuel consumption of the car will be more than 30 ~ 50L / 100km. Then the star engine of the 5/7/9 cylinder can output high power at high speed. Can its fuel consumption be acceptable to ordinary people?
Summary: Due to the two shortcomings of the very bad customer experience (NVH) and its very high energy consumption, the basic decision of this type of mobility tool does not have the probability of popularization. In addition, the cost of applying for an aviation driver's license is very high. Helicopters are hundreds of thousands. Once flying cars are popularized, there will be a series of problems, such as how to ensure low-altitude flight control or how to ensure road and housing construction. With the safety of the staff, this should be the key reason why decision-making flying cars always appear in film and television dramas.
Before the anti-gravity aviation was maintained, flying cars were useless, and now the high-tech level of civilized behavior seems to be anti-gravity is also a science fantasy. Do you still want to fly cars? Before capturing and conducting scientific research on the UFO, the car is still properly driving on the road!
