Zusammenfassung: This paper presents a novel concept for a highly efficient and ecological propeller-driven aircraft. The aircraft has a high wing, T-tail, and two turboprop engines with large propeller diameters decreasing disc loading and therefore increasing propeller efficiency. The aircraft also features a strut-braced wing with natural laminar flow. It is shown that direct operating costs can potentially be reduced by about 17 % while reducing trip fuel mass and therefore CO2 emissions by about 36 % compared to the reference aircraft Airbus A320.

Zusammenfassung: In this thesis, a methodology for life cycle assessment in conceptual aircraft design is being developed. Using this methodology, the environmental impact of the designed aircraft can be calculated. Additionally the driving in- and outputs, processes, life cycle phases, impact categories and design parameters for the environmental impact of aircraft can be identified. A turboprop aircraft serves as application example for the methodology. It is being optimized for minimum environmental impact and the results are being compared to those of a reference aircraft. Additionally, the methodology is applied to future aircraft concepts and their environmental impact is compared to that of the reference aircraft as well. The investigation of the turboprop aircraft shows that there is generally a high potential for reducing environmental impact. The reduction of fuel consumption and an adaption of flight altitude are identified as decisive factors. The environmental impact of the investigated future concepts is tending to shift from the flight to the production of the respective energy source. In the production process, the share of electric energy from renewable energy sources should be as high as possible to achieve minimum environmental impact. The integration of a life cycle assessment methodology into conceptual aircraft design allows to analyze and influence the environmental impact of future aircraft early in the design process.
