In this work, we integrate a mission analysis algorithm into the Multidisciplinary Airplane Research Integrated Library (MARILib), which is a multidisciplinary optimization tool for aircraft sizing. The main purpose of such an integration is to include aircraft operational data from the initial design process, to develop a more realistic aircraft design framework. With this approach, the design and mission requirements that reflect how aircraft actually operate are considered in the design process. Mission analysis tools are developed to model realistic aircraft operations. Data analytics, including clustering algorithms, is performed to extract information from flight data, which then becomes input to MARILib. The aim of the framework is to reduce operational costs of aircraft starting from the initial design itself, by incorporating air transportation data into the conceptual design stages.

Environmental life cycle assessment and operating cost analysis of a conceptual battery hybrid-electric transport aircraft

Noise and greenhouse gas emission targets set by e.g., the EU commission, NASA, and ICAO oblige the aviation industry to reduce its environmental footprint. Battery-powered hybrid-electric aircraft are currently being investigated in this regard as they can potentially reduce in-flight greenhouse gas emissions and noise. However, most studies to date have focused on the CO2 emission reduction potential instead of considering the total life cycle environmental impact. Hence, within this study an environmental life cycle assessment method for a hybrid-electric aircraft is developed and applied, supplemented by a direct operating costs analysis. This allows the simultaneous evaluation of the environmental impact reduction potential and the economic consequences for aircraft operators. This demonstrates the faced trade-off and contributes to a meaningful review process. A single-aisle transport aircraft (A320 class) serves as a use case for the established methodology. It consists of the conceptual aircraft design, the environmental life cycle assessment, and the direct operating costs analysis for a conventional reference aircraft and a hybrid-electric aircraft with a discrete parallel powertrain architecture. It should be noticed that the focus of this study is the comparison of conceptual aircraft designs of the same fidelity on system level, in lieu of the detailed modeling of a hybrid-electric aircraft. Results show that for a degree of hybridization of 0.3, the environmental impact of the hybrid-electric configuration increased by $$15.1\%$$ 15.1 % , while the operating costs increased by $$41.0\%$$ 41.0 % compared to a conventional reference aircraft. For a future scenario, favourable for hybrid-electric aircraft with i.a. renewable electricity production, the environmental impact could be reduced by $$7.0\%$$ 7.0 % compared to the reference aircraft. At the same time, the operating costs gap between both configurations decreases to $$+ 26.8\%$$ + 26.8 % . Hybrid-electric aircraft should therefore be investigated further as a potential solution to reduce the environmental impact of aviation, if simultaneously to developing them the expansion of renewable energies is fostered. Nevertheless, this reduction in environmental impact involves a high direct operating costs penalty.

“…The third is a steady, level flight assumption, which leads to the classic Bréguet range equation [23]. This assumption is commonly used for mass and endurance estimation at preliminary aircraft design stages for a single design point in software packages such as Multidisciplinary Airplane Research Integrated Library (MARILib) by ENAC, IRT Saint-Exupéry, and Airbus [24]. A limitation of this last approach is that it neglects important accelerated segments of flight which contribute to fuel burn in performance analysis.…”
