Energy-efficient Electric Jump Take-Off

在过去的十年里，全球资本市场的大规模资金投入到为新兴的先进空中机动领域提供商业上可行的、可认证的解决方案的探索中。目前，这些举措都没有产生任何商业上可行的、社会上可接受的、能够获得航空航天管理机构认证的概念。随着EASA在2022年中期发布SC.VTOL认证标准，3E-JTO项目变得更加复杂，旨在带来一个商业和社会可行的概念，以满足已发布的可认证标准。通过专注于为旋翼直升机或复合旋翼直升机的全翼展旋翼提供电力以实现跳跃起飞（JTO），这些飞机可以以仅一小部分的功率携带多旋翼飞机的两倍有效载荷/航程。JTO将允许飞机垂直起飞，但取消悬停能力。项目3E-JTO将专注于使用电池为全翼展旋翼供电的电力系统的集成和测试，需要小型电池组，逆变器和低转速高扭矩电动机。这些都是现成的组件，用于在测试台上测试系统。即使与其他电气解决方案相比，该项目也将在成本、社会和环境方面带来多重效益。例如，与传统推进系统相比，运营成本降低了50%，由于功率更低，电池更小，与当前VTOL解决方案相比飞机更大，以及由于技术实现了合理的飞机解决方案而改善了连接性。

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.
