As climate change is exacerbated and existing resources are depleted, the need for
sustainable industries becomes ever so important. Aviation is not an exception. Despite the …

Non-CO2 aircraft emissions are responsible for the majority of aviation's climate impact,
however their precise effect is largely dependent on the environmental conditions of the …

Meeting climate mitigation goals would require transformative changes in the transport
sector (high confidence). In 2019, direct greenhouse gas (GHG) emissions from the transport …

This paper presents an uncertainty and disturbance estimator (UDE)-based nonlinear robust
controller for close formation flight in light of the command filtered backstepping technique …

Current practices for investment and technology decision making in aeronautics largely rely
on regression-based cost estimation methods. Although quick to implement and easy to use …

Large-eddy simulations (LES) have been employed to investigate the far-field four-vortex
wake vortex evolution over 10min behind an aircraft formation. In formation flight scenarios …

The reduction of wingtip vortices is a critical and challenging task for aircraft wing-design.
Inspired by the wingtip morphology of soaring birds, Whitcomb created winglets to reduce …

Formation flight is one potential measure to increase the efficiency of aviation. Flying in the
upwash region of an aircraft's wake vortex field is aerodynamically advantageous. It saves …

An operational measure that is inspired by migrant birds aiming toward the mitigation of
aviation climate impact is to fly in aerodynamic formation. When this operational measure is …

This paper introduces an integrated approach for flexible-aircraft time-domain aeroelastic
simulation and controller design suitable for wake encounter situations. The dynamic …
