Abstract
The Coordinated Research Centre 880 (CRC 880) focuses on the development of a new active high-lift system, which enables short takeoff and landing, low fuel consumption, and low noise immission. In order to assess the active high lift system on an aircraft level, several vehicle variants, that are equipped with this active high-lift system, have been developed within the 9-year funding period of the CRC 880. This article describes the CRC 880 vehicle concepts and evaluates their advantages and disadvantages in detail. Furthermore, the noise prediction methodology is described and the noise immission of the vehicle concepts is evaluated on a comparative basis. Results indicate that a propeller-driven short takeoff and landing (STOL) aircraft is cost-efficient but has increased noise immission compared to a conventional turbofan aircraft. On the other side, STOL aircraft with turbofan engines located above and aft of the main wing for fan sound shielding are more expensive but offer significant noise reductions.
