Green Regional Aircraft (GRA)
The Green Regional Aircraft research programme (GRA), co-led by Leonardo Aircraft Division and Airbus D&S, has developed, delivered and integrated technologies to reduce noise and emissions of the future regional aircraft configuration. These include in particular advanced low-weight and high performance structures, incorporation of all-electric systems, bleed-less engine architectures, low noise/high efficiency aerodynamics, and environmentally optimised mission and trajectory management.
Throughout the Clean Sky programme lifetime, the Green Regional Aircraft ITD beneficiaries participated in many dissemination events across Europe.
Partners including SMEs, research centres and universities greatly contributed to reach the target shown in the table, by increasing performances year after year.
The figure below shows the production of the papers during the course of the project. Clean Sky 2 is certain that further publications have been made after the closure of the project and for this it invites the authors to report their works.
Paper Production for Year
Most of these works were produced by universities. This chart considers only the institution to which the first author of the paper belongs. However, it must be noted that more than 50% of GRA Clean Sky papers involve more than one organisation. This means that the participation of universities and industry (SMEs have been included in this category) in the project dissemination is higher than that indicated in the picture below.
Paper for type of organisation
More than 68% of all dissemination occurred in Europe, around 24% in the United States and about 8% in the rest of the world, as shown in this figure where the number of papers for country are reported.
