综合性网民问与答:飞行汽车是不是有普及化的概率?

2019-12-21 14:21

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?

正确答案:难度系数十分之高,高到不具有普及化的实际意义!

许多人觉得在科技时代沒有不可以保持的念头,殊不知却忽视了文明行为技术性级别的等级分类规范,参照卡尔达舍夫级别规范吧。

I:该文明行为(人类发展史)是大行星电力能源的主人家,可修罗神全部全球电力能源的综合性。

II:该文明行为可以搜集全部行星系统软件的电力能源。

III:该文明行为可以运用太阳系系统软件的电力能源为其常用。

会飞的汽车

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。

但以现在的高新科技水准是没法保持反重力的,因此飞行汽车则只能将会是二种形状:固定翼(伸缩翼)飞行汽车,旋翼机型或直升飞机型飞行汽车,其相互特性是应用星形活塞式发动机。

活塞式发动机与小车应用的活塞式发动机为同一定义,均为内燃式热机;差别为小车应用的是直列或水准对置型柴油发动机,设备的特性是“平躺着”,根据变速器接纳并变大柴油发动机輸出的扭距保持传动系统。而飞机场应用的柴油发动机则为星形构造,其特性为发动机曲轴坐落于正中间部位,活塞杆曲轴紧紧围绕发动机曲轴排序。

这类柴油发动机的优势是构造简易且品质轻,扭距挺大推重比很高;但这类设备也是比较突出的缺陷,实际有二点。

1:柴油发动机为立柱式构造,占有的空间构成十分大;针对小车来讲这类设备不适合应用,由于会挡住前档的视野,另外应用星型发动机只有保持后驱,由于发动机曲轴要指向小车的汽车后桥才可以根据变速器和转动轴輸出驱动力,殊不知加上容积粗大的纵置变速器,这类小车的武器装备品质必定会很高。整备质量高而一切正常安全驾驶必须的大马力会挺大,那麼起飞时必须的大马力则更大。星型发动机要想保持大功率輸出则务必以低挡位高速旋转运行,高速旋转会产生十分比较严重的难题,最先为高速旋转会提升柴油发动机的损坏减少使用期,次之高速旋转会产生极大的噪声和震动且星型发动机的震动本就很显著,但是这都并不是最关键的难题。

2:最关键的难题是耗油量,大家都知道内燃式汽车转速越高耗油量也会越高,由于转速比高而柴油发动机呼吸的负压力太大;柴油发动机的气体然料比为固定不动的,进供气量愈大点火提前角毫无疑问会同歩上升。一般的家庭装代步汽车以均值2000~3000转的低转速比行车,A/B级车的均值耗油量会在10L/100km上下;而假如安全驾驶设计风格激进派时间以4000~6000转的转速比行车,车子的耗油量则会很生动的超过30~50L/100km。那麼动则5/7/9缸的星型发动机以高速旋转輸出大功率,其耗油量能是平常人能够 接纳的吗?

小结:飞行汽车由于十分槽糕的客户体验(NVH)及其十分之高的耗能两大缺陷,基础决策了这类代步工具不具有普及化的概率。另外航空驾照报考的成本费都是十分高,直升机都是动则数十万;且飞行汽车一旦普及化则有将会导致一系列的难题,例如低空飞行无法控制或撞击后怎样确保路面房屋建筑与工作人员的安全性,这点儿应当是决策飞行汽车总是出現在影视剧中的关键缘故。

在沒有保持反重力航空以前,飞行汽车毫无用处,而现在的文明行为高新科技级别好像反重力也是科学幻想了,还希望飞行汽车吗?沒有捕捉并进行科学研究幽浮以前,小车還是妥妥的在道路行车吧!

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!
