Geared-elevator flutter study [PDF]

An experimental and analytical study was made of the transonic flutter characteristics of a supersonic transport tail assembly model having an all-movable, horizontal tail with a geared elevator. Two model configurations, namely, one with a gear-elevator

Challenges in Balancing Sustainability, Competitiveness and Geopolitics in Critical Mineral Supply Chains

Business Strategy and the Environment, EarlyView.
ABSTRACT The energy transition is driving demand for critical raw materials (CRMs), creating complex challenges for companies in CRM supply chains. This study examines how firms in Europe navigate the intersecting pressures of sustainability, competitiveness and geopolitical risk, based on interviews with industry representatives.

Wing/store flutter with nonlinear pylon stiffness [PDF]

Recent wind tunnel tests and analytical studies show that a store mounted on a pylon with soft pitch stiffness provides substantial increase in flutter speed of fighter aircraft and reduces dependency of flutter on mass and inertia of the store.

Exploring the Role of Prospect Theory for Fast‐Fashion Practice as Experienced Through a Generational Lens: Marketing an Environmental Business Strategy That Appeals to Fashion Identity and Time Horizon Values

Business Strategy and the Environment, EarlyView.
ABSTRACT The financially lucrative fast‐fashion business strategy is criticised for impacting detrimentally on the environment, with marketing tactics encouraging frequent‐impulsive fashion consumption. This research presents a novel conceptual framework merging fashion involvement values within prospect theory, creating a fashion‐identity‐time‐horizon

Wind-tunnel evaluation of NASA developed control laws for flutter suppression on a DC-10 derivative wing [PDF]

Two flutter suppression control laws were synthesized, implemented, and tested on a low speed aeroelastic wing model of a DC-10 derivative. The methodology used to design the control laws is described.
