日前，罗尔斯-罗伊斯在范堡罗航展公布了电动垂直起降（EVTOL，electric vertical take-off and landing）飞行器概念。EVTOL设计在个人和公共交通、物流和军事领域都有着广泛应用前景。罗尔斯-罗伊斯在该领域拥有大量技术储备，最早能在2025年前将概念变为现实。

A few days ago, Rawls - Royce announced the concept of EVTOL electric vertical take-off and landing at the airport. EVTOL design has broad application prospects in personal and public transport, logistics and military fields. Rawls Royce has a large number of technical reserves in the field, and the concept can be turned into reality as early as 2025.

EVTOL项目是罗尔斯-罗伊斯“倡导电气化”战略的重要部分，旨在打造全球领先工业技术企业。该概念设计基于罗尔斯-罗伊斯在火车舰艇用油电混合动力系统积累的经验，容纳其在燃气涡轮、垂直起降技术、系统分析以及航空法规和认证领域的专长，是罗尔斯-罗伊斯技术创新和系统整合能力的例证。EVTOL的商业化应用还需要与飞机制造商紧密合作，以及电气系统的一系列战略合作伙伴。

The EVTOL project is an important part of Rawls Roy's strategy of electrification. It aims to build a leading industrial technology company in the world. The conceptual design is based on the experience accumulated by Rawls - Royce in the oil and electric hybrid system of the train ships, accommodates its expertise in the gas turbine, vertical take-off and landing technology, system analysis, and aviation regulations and certification, and is an example of Rawls Royce's technological innovation and system integration capability. The commercial application of EVTOL also requires close cooperation with aircraft manufacturers and a series of strategic partners in the electrical system.

EVTOL概念飞行器通过燃气涡轮技术发电，为六台特别设计的低噪电动推进器提供动力。该飞行器还配备储能电池。采用混合EVTOL配置，该飞行器可以承载四到五人，以每小时最高达250英里的速度不间断飞行约500英里，期间电池通过燃气涡轮进行充电，能够利用停机坪和常规机场等现有设施。

The EVTOL concept aircraft powered by gas turbine technology provides power for six specially designed low-noise electric thrusters. The aircraft is also equipped with energy storage batteries. Using a hybrid EVTOL configuration, the aircraft can carry four to five people, flying uninterrupted about 500 miles at a speed of up to 250 miles an hour, during which the battery is charged through a gas turbine and can use existing facilities such as the apron and the conventional airport.

飞行器的机翼能够旋转90度，从而实现垂直起降。一旦上升至巡航高度，机翼上的推进螺旋桨可以折起，以降低阻力和机舱噪音。之后飞行器依靠两台后侧推进螺旋桨提供推力。随着城市化进程加剧，人口密度增加为常规交通系统造成巨大压力。EVTOL为高效低排个人空中交通提供了新的可能。

The wing of an aircraft can rotate 90 degrees to achieve vertical takeoff and landing. Once it reaches the cruising altitude, the propeller on the wing can be folded to reduce drag and engine noise. After that, the aircraft relies on two rear propulsion propellers to provide thrust. With the intensification of urbanization, increasing population density has caused tremendous pressure on conventional transportation systems. EVTOL provides a new possibility for efficient and low personal air traffic.

罗尔斯-罗伊斯电气化团队主管RobWatson表示：“电气化是工业技术的必然趋势，将为推进系统带来革命。依托我们在电气技术和航空领域的专长，罗尔斯-罗伊斯正在为电动和混动飞行开发潜在市场和应用。我们拥有得天独厚的优势，引领这一新兴领域的进程，同时也期待与行业伙伴开展合作。”

RobWatson electrification team leader Rawls said: "electrification is the inevitable trend of industrial technology, and will bring revolution to the propulsion system. Relying on our expertise in electrical technology and aviation, Rawls Royce is developing potential markets and applications for electric and hybrid flight. We have the unique advantage of leading the new field and looking forward to cooperate with our industry partners. "

“作为航空动力领域的先驱，罗尔斯-罗伊斯拥有可靠记录。从开发首台涡桨和喷气发动机，到制造全球最高效大型民航发动机和垂直起降解决方案，我们拥有雄厚的传统。随着航空业正开始进入第三个时代，现在正是我们再次引领行业的时候。”

"As a pioneer in the field of aviation power, Rawls Royce has a reliable record. From developing the first turboprop and jet engine to manufacturing the most efficient civil aero engine and vertical take-off and landing solutions in the world, we have a strong tradition. As the airline industry is entering the third era, it is time for us to lead the industry again. "

初始EVTOL概念飞行器采用M250燃气涡轮，嵌入飞行器后部，改装为混合电动推进系统的一部分。M250是罗罗极其成功的发动机，自半个多世纪前投入运营以来，已交付超过3.1万台，现役约1.6万台。M250发动机为170多种不同直升机和固定翼飞机提供动力，整个机队的累计飞行时间超过2亿小时。

The initial EVTOL concept aircraft adopts M250 gas turbine, which is embedded in the rear part of the aircraft, and is converted into a part of the hybrid electric propulsion system. M250 is a highly successful engine of Rolls Royce. Since its operation half a century ago, it has delivered more than 31 thousand units and has about 16 thousand units in active service. The M250 engine provides power for more than 170 different types of helicopters and fixed wing aircraft. The total flight time of the whole fleet exceeds 200 million hours.
