The Dynamic Characteristics of a non-linear main landing gear system of an aircraft during landing

, 2020
The landing gear plays a very important role during landing by absorbing the high impact energy of the aircraft. The main landing gear absorbs the bulk of the load to reduce the load experienced by both the aircraft fuselage and the nose landing gear. In

Charting the Course: Real‐World Application of Sustainability and Innovation Principles in the Portuguese Blue Economy Firms

Business Strategy and the Environment, EarlyView.
ABSTRACT The blue economy has emerged as a key sector for linking sustainability and innovation, yet existing research has largely overlooked how firms operationalize these processes in practice. This study addresses that gap by asking: How do Portuguese blue economy firms embed sustainability‐oriented innovation (SOI) into their strategies, and what ...

A systematic review evaluating the performance of eDNA methods relative to conventional methods for biodiversity monitoring

Ecography, EarlyView.
The rapid adoption of environmental DNA (eDNA) methods has drastically changed biodiversity monitoring efforts. It is often claimed that eDNA methods are more sensitive and efficient than conventional biodiversity monitoring methods, but it is often unclear what metrics support this claim.

Exploring the Spatial Dynamics of a Just Regional Energy Transition: What If We Ask Citizens?

Environmental Policy and Governance, EarlyView.
ABSTRACT The installation of wind turbines and solar parks in valued rural landscapes has led to local concerns and perceived injustices to the extent that the societal acceptance of the energy transition is at stake. Although the literature on energy justice is blooming, research into citizens' understandings of justice with regards to regional energy

Shared Waters, Shared Responsibility: Solving Collective Action Problems in an Upstream‐Downstream Setting

Environmental Policy and Governance, EarlyView.
ABSTRACT The governance of shared water systems requires collaboration across diverse stakeholders. In this study we advance the theoretical understanding of asymmetric collective action problems (CAPs) by reassessing the role of third‐party interventions and emphasizing the strategic importance of policy brokers and institutional venues.

Analysis of Global Sensitivity of Landing Variables on Landing Loads and Extreme Values of the Loads in Carrier-Based Aircrafts

International Journal of Aerospace Engineering, 2018
When a carrier-based aircraft is in arrested landing on deck, the impact loads on landing gears and airframe are closely related to landing states. The distribution and extreme values of the landing loads obtained during life-cycle analysis provide an ...
