The 'HyLiner' ESTOL Regional Jet - Economical Motivation, Technological Challenges and Current Status 2008

摘要

A predominant problem in the US as well as in Europe is the imminent capacity shortage of major hub airports. Concurrently, air traffic is assumed to increase significantly worldwide. But further runway extension of airports is difficult because of residents' resistance and limited land space availability. On the other side, the increasing market size gives a potential for new aircraft concepts. So the question arises, what type of aircraft will meet best the future market requirements.rnWe show that currently discussed solutions to airport capacity problems are mostly not in line with market requirements and have therefore not really the potential to alleviate the increasing capacity problems. We analyze to what extend an airplane with extreme short takeoff and landing (ESTOL) capabilities might be able to overcome these landside capacity problems and present the current technical challenges and progress in this area of research and give an overview on the current status of the "HyLiner" (Hybrid Airliner) ESTOL Regional Jet, including information about methods used for the conceptual design and the resultant different configurations that are investigated at the Bauhaus Luftfahrt (e.g. fan-in-wing and box-wing configurations).
