Integration and Digital Demonstration of Low-emission Aircraft Technologies and Airport Operations

通过减少航空的影响来实现气候中立的目标是一项任务，需要为发展破坏性技术和行动概念制定一份仔细起草的路线图。在特别关注机场当地机场区域的污染物和噪音排放的情况下，需要采取协同办法，将飞机方面和机场方面的干预措施结合起来。这需要协调努力，开发技术，不仅在巡航条件下提供好处，而且能够改善当地空气质量和机场地区的噪音，这些地区的污染物和烦扰已被证明对当地社区的发病率和死亡率影响相当大。Indigo是学术界、研究中心和机场之间的一个合作项目，旨在确定由于引入新的非常规中程飞机而导致的当地空气质量和噪音的改善幅度，这种新型非常规中程飞机具有基于混合电力/可持续和传统燃料动力系统的分布式推进，大展弦比机翼能够在机场附近的低空以零到低排放模式(即电动和SAF)安静地飞行，并且只有在需要时，例如在较高高度，或者在巡航期间为电池充电时，才使用传统航空燃料。Indigo将为下一代无声和清洁的中程飞机探索一种新的范例，以及这种新飞机将如何改变机场及其附近的运营。它将引入改进的方法来分析未来的航空环境影响，在不确定因素的过滤下，将能够考虑到非常规飞机的性能和未来的机场情景。

Achieving the goals of climate neutrality by reducing the impact of aviation is a task that requires a carefully drafted roadmap for the development of disruptive technologies and concepts of operations. With particular attention to the emissions of pollutants and noise in airport local airport areas, a synergetic approach is needed that combines together interventions on the aircraft side and on the airport side. This calls for coordinated efforts in developing technologies that not only provide benefits during cruise conditions but also are capable of improving the local air quality and noise in airport areas where the impact of pollutants and annoyance to local communities has been demonstrated to be quite large in terms of morbidity and mortality. INDIGO is a collaborative project between academia, research centres and airports that aims at identifying the margins of improvement in airport local air quality and noise resulting from the introduction of a new non-conventional mid-range aircraft featuring distributed propulsion based on hybrid electric/sustainable and conventional fuel powertrain and large aspect-ratio wings capable to fly quietly and in zero-to-low-emission mode (i.e. electric and SAF) at low altitudes near airports and resort to conventional aviation fuel only when required, e.g. at higher altitudes or to recharge batteries during cruise. INDIGO will explore a new paradigm for the next-generation of silent and clean mid-range aircraft and for the way such a new aircraft will allow transforming the operations “at and near” airports. It will introduce improved methods for the analysis of future aviation environmental impact that, under the filter of uncertainty, will be able to account for non-conventional aircraft performance and future airport scenarios.
