08:27查看AI文稿AI文稿eighty percent of the current most advanced ev tall projects are using well known open propellers as the main propulsion system this simple and straightforward approach allows manufacturers to quickly progress in the development of an ev tall aircraft to make it marketable， this is a great strategy from a business perspective in the future however， these companies could be facing real market application issues related to payload、 safety noise and scalability in this video， i will analyze the main advantages of ducted fans over unducted propellers and i will explore a new and advanced ev tall propulsion system that offers extra thrust during hover reduced aerodynamic drag a forty percent greater efficiency and has the ability to assist the aircraft in the transition from hover to cruise flight the design of ev tall aircraft for passenger transport is a new field and it is driven by five degrees of freedom payload、 speed、 range、 noise and simplicity these degrees of freedom are firmly connected and the improvement of one parameter often disadvantages one or more of the others the choice of an ev tall design determines a trade off between the different degrees of freedom this ultimately dictate the crews and hover efficiency and the noise emissions of the aircraft a low noise aircraft is crucial to enable market access to inner city operations a major advantage of ducted fans over unducted propellers is that the duck acts to significantly mitigate noise， both blade passing noise and broadband noise this is achieved both by the presence of the duct and by acoustic liners mount within them nearly all blade tip losses and swirl losses are removed， thanks to the duct in the presence of stater veins， the design of the fan blades and stator veins is optimized to reduce noise emission in a similar manner to commercial jet engines further noise reduction can be achieved by the addition of acoustic liners to the internal walls of the duck structure ducted fans have efficiency advantages that arise from the presence of the duct the duck generates straight inflow on fan blades with low turbulence blade tip losses are reduced and the presence of a state of row removes exit swirl during hover open rotors are between eighty five and ninety percent less efficient than well shaped ducted fans at the same disc load nearly all blade， tip losses and swirl losses are removed， thanks to the duct and the presence of stator veins， the two main disadvantages of ducted fans are higher power requirement because of the higher disc loading the hover power consumption is higher than for open propeller aircraft additional aerodynamic drag and weight the duct generates drag during cruise flight and increases overall weight in order to minimize these two main drawbacks of traditional ducted fans a californian startup is developing a more powerful yet simple new kind of ev tall propulsion system that could become the new standard for urban air mobility aircraft one way to further improve the efficiency of ducted fans is by allowing the maximum amount of air to be drawn into the duct with minimum loss this can be achieved by adding a bell mouth inlet， which is a form of convergent inlet air duct used to direct air into the inlet of a ducted fan or a gas turbine the californian startup， xc and solutions has developed a propulsion system consisting of a bellmouth transformable ducted fan the team began to develop and propel this next generation ducted fan propulsion system back in twenty nineteen after many studies with air physics applied to ducted fan surfaces and using the burnilly law the team discovered the huge potential of adaptive ducted fan and build its first prototype during takeoff landing or hovering when the power consumption is greater， the bellmouth is deployed the deployed adaptive ducted fan is a duct fan with a bell mouth convertible mechanism for the inlet duct section that gives a very substantial area increase this configuration provides the maximum amount of air in the duck combined with the difference of air pressure significantly increases thrust during vertical takeoff and landing the retracted adaptive ducted fan is a ducted fan with a sharp nacille design this mode is intended for crews or straight flight due to the enched aerodynamic section of the hull the mechanical adaptation deployed to retracted of adaptive ducted fan takes less than three seconds it is important to mention the considerable performance advantages of adaptive ducted fans over traditional fixed geometry ducted fans to achieve similar hover efficiency a fixed geometry ducted fan has to be sixty percent larger in size than an adaptive ducted fan the volume of a fixed geometry duct is over four times larger than the retracted adaptive ducted fan also， there is likely a very substantial weight advantage associated with it the cruise drag of retracted adaptive ducted fans will also be less than half that of the large fix geometry ducted fan or retracted adaptive ducted fan offers a fifteen to twenty percent increase in propulsive efficiency relative to the larger fix geometry ducted fan this has a direct impact on range and maximum speed capability one of the critical stages of an ev tall flight mission is the transition from hover to cruise flight an adaptive ducted fan can improve the flight dynamics during the transition by varying the inlet aperture of the ducted fan the adaptive ducted fan has two working regimes automated segmentation and distribution of intake flaps helpful for hovering to cruise transition， minimizing drag and improving control ability uniform retracted and deployed regime standard mode depending on various weather conditions in different atmospheric pressure these two regimes combined will maximize the flight control efficiency the company envisions the integration of the adaptive ducted fan system into two main vehicle classes a seven seat hybrid powered v tall aircraft designed for regional air mobility and driven by four adaptive ducted fan thrusters an ev tall cargo on manned aerial vehicle designed for cargo and especially ultra heavy loads it intends to disrupt container operation costs and logistics of the poor industry the adaptive ducted fan system offers the potential for good hover and cruise efficiency for a representative ev all application in hover the deployed adaptive ducted fan matches the hover performance of a much larger fixed geometry ducted propeller further optimization of the adaptive ducted fan design may allow up to ten to fifteen percent improvement in hover performance the reduced volume of the adaptive ducted fan will contribute to lower weight relative to the larger fixed geometry duck the retracted adaptive ducted fan configuration contributes to lower dragon cruise flight enhancing the potential for higher flight speeds in longer range the adaptive ducted fan also offers the ability to adjust the duck geometry in transition between hover and cruise flight greatly assisting the flight control if you learned something from this video， please give it a like and if

02:19查看AI文稿AI文稿大家好，二零二六年世界无人机大会今天圆满结束了，最近腿都整废了，但真的有被震撼到，今天不绕弯子，直接给大家聊一聊本次大会最火的主角， evatar， 也就是空中出租车。先说一下 evatar 是 什么？ 说白了，它就是电动垂直起降飞行器，你可以把它想象成一个大号的无人机，加一个豪华的座舱，不用跑道，原地起飞。目前主要有三种形态， 多旋翼的，像放大版的无人机飞不远，复合翼的能垂直起降又能平飞，是现在的主流。还有一种轻转旋翼，飞的最远也最难做。那为啥他突然间这么火？核心就三个字，快、省、近、快。从深圳会展中心飞到珠海中山，原来堵车两小时，他半个小时给你送到，省！ 电动系统维护成本只有直升机的三分之一，单座每公里成本能做到二十元以内。近纯电驱动，噪音很小，不会像直升机那样一起飞就被投诉。 而且有个事你可能不知道， evo 超过百分之七十的核心技术与电动车是共通的，你完全可以把它理解成会飞的新能源车， 这发展速度能不快吗？但光快没用，想载人必须先拿证。圈内有句话，四行证就是飞行器的出生证，没它不能卖票。载客这玩意要拿起四证，其中最难的型号是合格证， 动不动就要折腾三到五年。目前全球唯一市政齐全的是一行的 e h 二幺六 s。 不 过玉峰未来莫非长空、小鹏会天、广汽高域这些预计今年就能拿下证。所以二零二六年很有可能就是空中出租车正式拉客的圆点， 你现在经常听到一机难求，不是因为没人造，而是合规安全，能量产的真的太稀缺了。政策这边更是直接开绿灯，低空经济已经开始写进政府工作报告，新修建的 民用航空法直接把零到一百二十米化为自主飞行区，各地掏钱也掏的非常猛，上海给 evo 整机项目最高补贴一个亿，深圳开放了百分之七十城区的一百二十米以下空域，广州直接砸了两百亿的产业基金，大家就是在这样抢这个万亿级的赛道，那这玩意到底能干什么？ 我直接说重点打飞的上下班成绩，通勤，美团的无人机已经在深圳送了六十多万单外卖，山区救援物资空投，还有现在最热的低空文旅作者看山海 e v t 不 再是画饼了，而是真真切切的要从科幻开进我们的日常了。 未来以来只是还没有均匀分布，说不定没几年你真能打个飞的去上班。觉得有用的点个赞，评论区咱们聊一聊。
