Effect of Gyroscopic Couple on Aircraft Landing Gear Shimmy [PDF]
, 2023 This article presents the effect of gyroscopic couples on the shimmy response of landing gear. The gyroscopic effect between the rotational motions of the aircraft’s longitudinal and vertical axes may be one of the causes of shimmy.

Nose Landing Gear Shimmy Analysis with Variable System Stiffness Under Time-Varying Load
AerospaceVertical load fluctuations alter nose landing gear (NLG) system stiffness and complicate shimmy dynamics. Based on the full-scale NLG static stiffness test data, the relationship between shock absorber stroke and system stiffness was fitted, and a ...

Shimmy analysis of light weight aircraft nose wheel landing gear [PDF]
, 2022 This paper presents mathematical modeling and analysis of shimmy oscillations for a light weight airplane single wheel nose landing gear. Shimmy is a self-excited oscillation which occurs usually on the nose wheel landing gear assembly during ground ...

How can children and young people have a voice in urban treescapes?
People and Nature, EarlyView.Abstract Scientific understanding of climate change has, to date, failed to result in sufficient action. This paper proposes that a deficit model of top‐down learning and dissemination in relation to public engagement with science may be part of the problem, particularly when considering the attitudes, values and empowerment of children and young ...

Przejawy pornografii według prasy katolickiej w II Rzeczypospolitej
Nasza Przeszłość, 2021 Na przestrzeni lat rozumienie pojęcia pornografia uległo istot-nym zmianom. Przekonujemy się o tym, analizując polską międzywojenną prasę katolicką. Występujące tam definicje omawianego zjawiska odbiegają od współczesnych norm kulturowych.

Predicting the Remaining Useful Life of Landing Gear with Prognostics and Health Management (PHM)
Aerospace, 2022 Landing gear is an essential part of an aircraft. However, the components of landing gear are susceptible to degradation over the life of their operation, which can result in the shimmy effect occurring during take-off and landing.

CSRcalculator: A reproducible framework for understanding plant ecological strategies
PLANTS, PEOPLE, PLANET, EarlyView.Understanding how plants respond to environmental change is essential for conserving biodiversity and managing ecosystems under climate change. We developed CSRcalculator, an open‐source platform that brings together major competitor, stress‐tolerator, ruderal (CSR) models to make ecological strategy classification accessible, reproducible and scalable.
