Sustainable Development, EarlyView.ABSTRACT Air transport is one of the fastest‐growing sources of greenhouse gas emissions, yet it remains one of the most difficult sectors to decarbonize. The sector's climate impact is amplified by two factors: the steady rise in passenger demand and the absence of commercially viable low‐carbon technologies for long‐haul flights.

Conceptual design synthesis of fighter aircraft
, 2020 The aim of this thesis is to analyze the effects of initial engine scaling (using a competitor aircraft aerodynamic performance) on fighter aircraft conceptual design activities. A design synthesis including engine scaling, configuration development, fixed aircraft analysis, fixed wing aircraft sizing and optimization methodology has been developed ...

Highly Dynamic Soft Electrohydraulic Origami Actuators for Agile and Multimodal Robotic Locomotion
SmartBot, EarlyView.Most current soft robots still lag far behind their natural counterparts in both agility and speed, mainly attributed to the limited morphing modes and performance of soft actuators. Here, the authors report a new methodology of electrohydraulic origami (EHO) for creating powerful and multimodal soft actuators with large strain, high speed, lightweight,
