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）
