The final report focused on the detailed design of the final chosen concept, which is a BWB aircraft with a distributed propulsion system powered by liquid hydrogen. Before doing the actual technical design part, a market analysis is made to investigate the future demand for this type of aircraft. To do so, the SWOT analysis, market characteristics, and competitor analysis are made. After that, an estimation of the market dynamics & trends, as well as the expected demand for the aircraft is made. In financial analysis, the financial forecast and strategies for the whole aircraft program are discussed, from which the unit cost, operational cost, return on investment and cost-breakdown structure can be found. The report concludes that the Lightning2 program is a promising step towards more sustainable aviation. It emphasizes the need for further development and adaptation to technological advancements to maintain a competitive position in the market​

Reducing the emissions of ultra-fine particles in the vicinity of airports to minimise detrimental health effects for near-airport residents and airport personnel has been the main objective of the project. This report details the realisation of this goal which was done by designing a hybrid aircraft with notable improvements in the efficiency and emission characteristics. The aircraft in question is named the ’Low Emission Alternative Fuel’ aircraft, or ’LEAF’. Design of essential components and systems is presented along with evaluation of aspects needed for LEAF aircraft to enter the market by 2035.
