Energy-efficient Electric Jump Take-Off

在过去的十年中，全球资本市场投入了大量资金，为新兴的先进空中交通领域提供商业上可行的、可认证的解决方案。目前，这些倡议都没有产生任何商业上可行的概念，为社会所接受，并能够获得航空航天管理机构的核证地位。随着EASA在2022年中期发布SC.VTOL认证标准，情况变得更加复杂。3E-JTO项目旨在带来一个商业和社会上可行的概念，将满足公布的认证标准。通过专注于为旋翼机或复合旋翼机的全跨度旋翼提供电力以实现跳起起飞（JTO），这些飞机可以携带比多旋翼飞机多倍的有效载荷/航程，而功率仅为多旋翼飞机的一小部分。JTO将允许飞机垂直起飞，但取消悬停能力。3E-JTO项目将专注于使用电池为全跨度转子供电的电力系统的集成和测试，需要一个小电池组、逆变器和低转速高扭矩电动机。这些将是现成的组件，用于在测试平台上测试系统。与其他电力解决方案相比，该项目将在成本、社会和环境方面带来多重效益。例如，与传统推进系统相比，该系统的运营成本降低了50%，由于功率更低，碳足迹更小，电池更小，与目前的垂直起降解决方案相比，飞机更大，并且由于该技术能够实现合理的飞机解决方案，因此连接性得到了改善。

The last decade has witnessed large-scale funding from global capital markets into the quest to produce commercially viable, certifiable solutions for the emerging Advanced Air Mobility domain. At present none of these initiatives has produced any commercially viable concepts that are socially acceptable and able to attain certification status from aerospace regulatory bodies. Having become even more complex with the publication of the SC.VTOL certification standard by EASA in mid-2022\.Project 3E-JTO seeks to bring a commercially and socially viable concept that will meet published certifiable standards. By focusing on electrically powering a full-span rotor of a gyrocopter or compound gyrocopter to achieve jump take-off (JTO), these aircraft can carry double the payload/range over multirotor aircraft at only a fraction of the power. JTO will allow the aircraft to take-off vertically but removes the ability to hover.Project 3E-JTO will focus on the integration and testing of the electrical power system using batteries to power a full-span rotor, requiring a small battery pack, inverter and low rpm high torque electric motor. These will be off-the-shelf components used to test the system on a test rig.The project will bring multiple benefits in cost, societal and environmental even when compared to other electric solutions. Such as 50% operating costs compared to conventional propulsion systems, a smaller carbon footprint due to lower power, a smaller battery, and larger aircraft to current VTOL solutions and improved connectivity due to the technology enabling a sensible aircraft solution.
