飞行汽车18个螺旋桨就能带你飞

2019-09-20 23:47

2010年,1个称为Volocopter的精英团队明确提出1个idea:

无人飞机即然能够垂直起降,那能不可以载上人们?

都没想到,这一idea并沒有滞留在随便说说罢了。次年,她们连续打造出了几款原型机:VC1、VC2。结构并不复杂,仅仅是利用十几组螺旋桨,就能顺利载起一个人。

idea的取得成功认证,驱动器着Volocopter乘热打铁。2013年,她们公布了概念机VC200。而到2016年,实验飞机场则在德国开展了初次首飞。

这期内,Volocopter的一连串行为也吸引住了风险投资的集中注意力。2013年,她们取得50万欧的種子轮股权融资。2017年8月,由戴姆勒参加、intel跟投的2500万余元欧股权融资,正是这一年,他们推出了一款真正成熟的产品:2X。

6个Y型支撑组成飞机螺旋桨支撑架,每根支撑上带3个飞机螺旋桨,总共18个飞机螺旋桨构成了多旋翼飞行器。

飞行汽车总重290kg,可负荷160kg,等于2个成年人男士的净重。(或许,休重很大的男性显而易见超出这一大数字)

和无人飞机相同,2X飞行汽车选用电力工程驱动器。填满一回电,航空时间为30分鐘,续驶为30km。

而从2017年公布刚开始,Volocopter 2X依次在阿联酋、赫尔辛基、马来西亚取得了航空批准支付牌照,并且全都顺利完成了试飞。其中,既有飞行员驾驶,又要自动驾驶测试。

单纯性的检测毫无疑问不足,这期内,她们花销了很多時间处理商品难题:安全性、噪音、热耗。

安全性:从2011年的初次首飞起算,始终到2019年。8年里,Volocopter总共开展了超出1000次的航空检测。

他们希望向空管机构证明一点:哪怕飞行汽车大批商业化运营,与传统飞机之间的关系也可以完全协调到位。

只能这种还不足,Volocopter了解:客户针对飞行汽车的安全系数自始至终怀有隔阂。产成品迭代更新全过程中,相继再加了预留充电电池、多个降落伞,用于避免飞行汽车失事。

设计产品、检修、操作工学习培训、生产制造,照着国际航空机构提供的标准运行,在这个基础之上,再去设计安全冗余。

最终,他们通过了欧盟航空安全局(EASA)的安全标准。

噪音:直升飞机的噪声有多少,绝大部分人都深有体会。假定,一大群飞行汽车以直升飞机一样的噪声聚集航空,又是啥感受?也许很怕想像。Volocopter最初就想起了这一点儿,她们发觉:人们的触觉针对单一化的突显噪音非常敏感。而对几处分散的微弱噪声,感知并不明显。

从其实着手,她们减缩了18个飞机螺旋桨的盘片净重。最后实际效果就是说:由直升飞机的1个飞机螺旋桨噪声源,分散化为飞行汽车上的18个飞机螺旋桨噪声源。

Volocopter的官方网站出示了那么1组统计数据:一样飞行高度上(75米),直升飞机的噪声分贝为82dB,Volocopter 2X的噪声分贝则为65dB,仅仅比人类正常谈话的声音略高几个分贝。

热耗:针对飞行汽车而言,最耗电量的行车环节就是说垂直起降。不论是起降還是着陆,全部升力必须由推动系统软件承担。Volocopter向社会公布过1组统计数据:她们的2X在垂直起降环节,功率达到500-1000kW。

这一大数字哪些定义?就算起降、着陆時间只能短短的3分鐘時间,也得以耗光50kWh的用电量,这等于一辆汽车规范续航力版本号的特斯拉汽车Model 3。

更难的还要后边:航空间距越来越远,充电电池包的净重也越多大,均值计算下来耗能越高。

也正是这样,Volocopter才选择将2X的续航里程定为30km,追求能耗效率。

当然,负面影响也不小,直接导致他们的飞行汽车一次只能行驶30分钟。最终,迫使他们采用换电的方式投入未来的商业化运营。

In 2010, an elite team called Volocopter explicitly proposed an idea:

The drone can now take off and land vertically. Can it be loaded with people?

I did not expect that this idea was not stuck in casual talk. The following year, they successively built several prototypes: VC1 and VC2. The structure is not complicated, just using a dozen sets of propellers, you can successfully carry a person.

The idea was successfully certified, and the drive was driven by Volocopter. In 2013, they announced the concept machine VC200. By 2016, the experimental airport launched its first first flight in Germany.

During this period, Volocopter's serial series also attracted the attention of venture capital. In 2013, they acquired a seed round of equity financing of 500,000 euros. In August 2017, Daimler participated in the instalment and investment of more than 25 million yuan in equity financing. It was this year that they launched a truly mature product: 2X.

Six Y-shaped supports form the aircraft propeller support, each with three aircraft propellers, and a total of 18 aircraft propellers constitute a multi-rotor aircraft.

The flying car has a total weight of 290kg and can load 160kg, which is equal to the net weight of two adult men. (Perhaps, men who are heavily rested are clearly above this big number)

Like a drone, the 2X flying car uses an electric engineering drive. Fill in a callback, the air time is 30 minutes, and the driving time is 30km.

Since the announcement in 2017, Volocopter 2X has obtained aviation approval payment licenses in the UAE, Helsinki and Malaysia, and all successfully completed the test flight. Among them, there are both pilots and automatic driving tests.

There is no doubt that simple testing is insufficient. During this period, they spent a lot of time dealing with commodity problems: safety, noise, and heat consumption.

Safety: From the first flight in 2011, always until 2019. In eight years, Volocopter conducted more than 1,000 aviation tests.

They want to prove to the air traffic control agency that even if a large number of commercial vehicles are commercialized, the relationship with the traditional aircraft can be fully coordinated.

Only this is not enough, Volocopter understands: the safety factor of the customer for the flying car is always from the beginning to the end. During the iterative update of the finished product, a reserved rechargeable battery and multiple parachutes were added to avoid the crash of the flying car.

Design products, maintenance, operator training, manufacturing, operating according to the standards provided by international aviation agencies, on this basis, design safety redundancy.

In the end, they passed the safety standards of the European Aviation Safety Agency (EASA).

Noise: How much noise the helicopter has, most people have a deep understanding. Suppose that a large group of flying cars gather aviation with the same noise as helicopters. Maybe I am afraid of it. Volocopter first thought of this, they found that people's sense of touch is very sensitive to the singularity of the noise. For a few scattered weak noises, the perception is not obvious.

In fact, they started to reduce the net weight of the 18 aircraft propellers. The final practical result is that one aircraft propeller noise source from the helicopter is decentralized into 18 aircraft propeller noise sources on the flying car.

Volocopter's official website shows a set of statistics: at the same flight altitude (75 meters), the helicopter's noise decibel is 82dB, and the Volocopter 2X's noise decibel is 65dB, which is only slightly higher than the human voice. decibel.

Heat consumption: For the flying car, the most power-consuming driving link is vertical take-off and landing. Whether it is taking off or landing, all lift must be borne by the system software. Volocopter has published a set of statistics to the public: their 2X is in the vertical takeoff and landing, the power reaches 500-1000kW.

What is the definition of this big number? Even if the landing and landing time can only be as short as 3 minutes, it can consume 50kWh of electricity, which is equal to the Tesla Model 3 of a car's standard endurance version.

It is even more difficult to be behind: the air distance is getting farther and farther, and the net weight of the rechargeable battery pack is also larger, and the average energy consumption is calculated.

This is exactly the case, Volocopter chose to set the 2X cruising range to 30km, pursuing energy efficiency.

Of course, the negative impact is not small, which directly leads to their flying car can only travel for 30 minutes at a time. In the end, they are forced to invest in future commercial operations.
