When there is a need to move cargo across the world in the fastest possible manner, airlift is the prime solution. Due to the potential extreme requirements of airlift, aircraft have to be capable of performing in a myriad of operational environments. To support future aircraft design loops, this work proposes a framework which couples aircraft...

The potential for a correction by Rethorst for Vortex Lattice Methods (VLMs) exists to improve Longitudinal Static Stability predictions when applying the Rethorst correction to a slipstream engulfed horizontal stabilizer. The Rethorst correction has already proven to result in accurate lift predictions in VLMs for an isolated wing in a...

The Flying-V aircraft concept promises better fuel-burn performance over conventional tube-and-wing configurations, integrating the passenger cabin and cargo volume into the lifting surface. However, the wing-fuselage and cockpit windows of the Flying-V are exposed to the flight direction, posing a new challenge to the design and...

Various research initiatives in hybrid-electric/sustainable aviation typically address only a single vehicle or single vehicle class. However, novel propulsion and energy solutions can be expected to be differently applied in different vehicle classes. The objective of the EU funded research project CHYLA (Credible HYbrid eLectric Aircraft) is...

The aircraft’s environmental performance on fleet level is so far completely decoupled from the design process. The climate impact from aviation arising from non-CO2 effects are largely independent from CO2 emissions, but rather depend on the atmospheric state. Previously complex climate-chemistry models were used to evaluate the non-CO2...

Decades of improvements of engine efficiency on internal engine components through better materials, design methods and novel fabrication techniques have resulted in fuel consumption reductions. Another major factor for improving engine fuel consumption has been the increase of bypass ratio. However, this has a significant impact on engine...

Given the comparably high impact of aircraft emissions, especially their non-CO2 effects, on climate in the order of 5%, aviation stakeholders are required to act to reduce the warming effects of air traffic. Besides new operational procedures, like e.g. climate-optimized routing, this demands the development of completely new global-warming...

The design and integration of the propulsion system is known to be an interesting, multi-disciplinary challenge in aircraft design projects. Especially for new aircraft configurations, it is important to gain a lot of knowledge in the preliminary design stages. An example of such an unconventional configuration is the box-wing aircraft examined...

A process to efficiently design composite wing boxes is presented. It uses analytical and semi-empirical equations for failure modes such as material strength, plate buckling, stiffener column buckling and stiffener flange or web crippling. Laminate layups for the different components are selected in accordance with basic engineering rules...
