飛行汽車真正飛入生活還面臨多重瓶頸和阻礙

隨著飛行汽車在車展上亮相，讓很多人不禁高呼：“告別擁堵，我要飛得更高！”但是實際上，與堵在高速路上的噩夢說再見的動人時刻，未必很快到來。張揚軍指出，飛行汽車的發展目前還處于從研究探索走向商業化應用的早期階段。言外之意，以飛行汽車為載體的城市空中交通，將顛覆人們傳統的出行方式。但要實現這一美好愿景，還面臨著許多瓶頸和障礙。

    張揚軍說，第一是規則問題。其中涉及城市空域管理，包括“航線”的制定、行駛的規則、事故責任的劃分、空中執法手段等。目前為止全球沒有任何針對飛行汽車認證和空中交通管理的清晰、統一的標準及規章體系。

    第二是市場問題。例如，飛行汽車采用電動化分布式推進，實際運行噪聲遠比直升機小，但城市空中交通的運行頻次較現有直升機城市運行要密集很多，對城市人類生活到底會產生多大影響，公眾能否接受都尚未可知。此外，城市空中交通的基礎設施、運營模式、經濟成本，以及用戶體驗等也都未見雛形。

    第三是技術問題?！?a href="http://www.sacramento-business.com/" >飛行汽車性能主要涉及車體結構、飛控駕駛和動力推進三大技術領域。由于動力推進技術有其自身特有的專業技術門檻和難度，所以有關飛行汽車性能的技術研究，無論是讓汽車飛起來的早期探索，還是現在面向城市空中交通的研發實踐，都主要集中在車體結構和飛控駕駛這兩大技術領域，而對于動力推進，更多的是對已有的技術和產品進行選型、系統集成和應用，專門針對飛行汽車動力推進的研究相對較少。動力推進的瓶頸會導致飛行汽車的有效載荷低、航程短，是當前飛行汽車性能研發面臨的最主要問題和挑戰?！睆垞P軍說。

    As the flying car was unveiled at the auto show, many people couldn't help shouting: "Farewell to the congestion, I want to fly higher!" But in fact, the moving moment of saying goodbye to the nightmare stuck on the highway may not come soon. Zhang Yangjun pointed out that the development of flying cars is still in the early stage of moving from research and exploration to commercial application. The implication is that urban air transportation with flying cars as the carrier will subvert people's traditional way of travel. But to realize this beautiful vision, there are still many bottlenecks and obstacles.

    Zhang Yangjun said, the first is the issue of rules. It involves urban airspace management, including the formulation of "routes", driving rules, division of accident responsibilities, air law enforcement methods, etc. So far, there is no clear and unified standard and regulatory system for flying car certification and air traffic management in the world.

    The second is the market issue. For example, flying cars use electric distributed propulsion, and the actual operating noise is much lower than that of helicopters, but the frequency of urban air traffic operations is much intensive than the existing helicopter urban operations. How much impact will it have on urban human life? Is it acceptable to the public? None is known yet. In addition, the infrastructure, operating mode, economic cost, and user experience of urban air transportation have not yet seen embryonic form.

    The third is technical issues. “Flying car performance mainly involves three major technical fields: car body structure, flight control driving, and power propulsion. Because power propulsion technology has its own unique professional technical threshold and difficulty, the technical research on flying car performance, whether it is to make the car fly The early exploration, or the current research and development practice for urban air traffic, are mainly concentrated in the two technical fields of car body structure and flight control driving. For power propulsion, more is the selection of existing technologies and products. There are relatively few researches on the power propulsion of flying vehicles. The bottleneck of power propulsion will lead to low payload and short range of flying vehicles. This is the main problem and challenge facing the performance research and development of flying vehicles" Zhang Yangjun said.（圖文僅供參考侵刪/飛行汽車  www.feiauto.com）
