Execution of very low energy renovation through an integrated approach of new technology

From the previous LEHR-project, it became clear that many retrofit projects are executed in a very fragmented way: many actors do a certain part of the works, without cooperation or coordination. Sometimes, there is a lack of attention for works that have been executed already, or the works that have to be executed afterwards are not kept in...

Formation flying as an innovative air transportation system for long-haul commercial flight: A focus on operational feasibility and potential gain

Formation flying is introduced as a new and innovative air transportation system for long-haul commercial flight. With this paper the operational feasibility of formation flying is addressed, both from a market demand and economic, as well as an air traffic control perspective. Preliminary results of a case study indicate that operating a newly...

Integrated Design of a Long-Haul Commercial Aircraft Optimized for Formation Flying

The airline industry is under continuous pressure to reduce emissions and costs. This paper investigates the feasibility for commercial airlines to use formation flight to reduce emissions and fuel burn. To fly in formation, an aircraft needs to benefit from the wake vortices of the preceding aircraft. This requires a stable aerodynamic flow,...
