但是对于短途旅行——任何小于35公里(22英里)的地方——单人内燃机车比单人VTOLs使用更少的能源，产生更少的温室气体排放。这是一个重要的考虑因素，因为地面车辆的平均通勤距离只有17公里(11英里)。研究报告的撰写者之一、密歇根大学环境与可持续发展学院(U-M School for Environment and Sustainability)和罗斯商学院(Ross School of Business)的研究生吉姆?“因此，VTOLs在可持续移动系统中的贡献和作用将受到限制。”
The researchers analyzed primary energy use and greenhouse gas emissions in five phases: take-off hover, climb hover, cruise hover, descent hover, and landing hover. These aircraft consume a lot of energy during take-off and climb, but are relatively efficient during the cruise phase and can reach speeds of up to 150 miles per hour. Therefore, VTOLs are the most energy-efficient in long-distance travel, and the total flight mileage is dominated during the cruise phase.
But for short trips - anywhere less than 35 kilometers (22 miles) - single-person diesel locomotives use less energy than single VTOLs, producing less greenhouse gas emissions. This is an important consideration because the average commuting distance of ground vehicles is only 17 kilometers (11 miles). One of the authors of the study, the UM School for Environment and Sustainability and the graduate student of the Ross School of Business, Jim? "Therefore, the contribution of VTOLs to sustainable mobile systems And the role will be limited."
Not surprisingly, VTOL completed a 100-kilometer base flight, much faster than a ground vehicle. The point-to-point vertical take-off and landing (VTOL) flight path, combined with higher speeds, saves approximately 80% of the time compared to ground vehicles. "In general, aircraft electrification is expected to fundamentally change the aerospace industry in the near future. The authors of the study point out that many other issues need to be addressed to assess the viability of VTOLs, including cost, noise, and social and Consumer acceptance.
