Experiment and simulation research on the effect of airframe flexibility on landing load
Hangkong gongcheng jinzhan, 2020 Due to the increasing utilization of new materials and structures in modern airline, the flexibility of the airframe is increasing, and the coupling between the airframe and landing gear system during landing cannot be ignored.

Integrative Conservation, EarlyView.This study presents a comprehensive review of the 500‐year spatiotemporal evolution of global botanical gardens, identifying three major development stages—initial exploration (1543–1699), steady expansion (1700–1899), and rapid proliferation (1900–2020)—with six distinct sub‐stages. We propose a tripartite driving framework grounded in colonial botany

Irrigation and Drainage, EarlyView.ABSTRACT Long‐term economic analyses of variable rate irrigation (VRI) strategies were performed compared with uniform irrigation management (UIM) in a reference production field using the AquaCrop model. Five strategies to trigger irrigation were as follows: (Field Capacity‐VRI, Driest Soil Trigger‐VRI, Water Mining‐VRI, Conventional Uniform ...

Journal of International Development, EarlyView.ABSTRACT Field visits are common phenomena with non‐governmental organisations in Uganda. During these visits, Ugandan national staff guide visitors on series of meetings and interactions in the field. Following an actor‐oriented approach and drawing on ethnographic data on 14 field visits, this paper understands the field visit as a microcosm for the ...

Physics-based aeroacoustic modelling of bluff-bodies
, 2009 In this work physics-based modelling of bluff-body noise was performed with application to landing gear noise production. The landing gear is a primary contributor to airframe noise during approach.

Study on impact of test loading on sudden extension performance of dual-chamber buffers
Hangkong gongcheng jinzhanThe take-off angle of attack is increased by extending the nose landing gear suddenly at the end of the stroke during catapult take-off. The measurement of the sudden extension performance of landing gear is of great significance for the development of ...

Bifurcation and stability analysis of aircraft turning manoeuvres [PDF]
, 2008 During ground manoeuvres a loss of lateral stability due to the saturation of the main landing gear tyres can cause the aircraft to enter a skid or a spin. The lateral stability is governed not only by aspects of the gear design, such as its geometry and

Living on the edge: Habitat characteristics of northern myotis at the periphery of its distribution
The Journal of Wildlife Management, EarlyView.Northern myotis selected tall trees with minimal decay, in patches with other roosting options. In our study area, these trees occurred in narrow bands within an agricultural matrix, differing from contiguous forest at the core of the species' distribution. Nevertheless, bats selected the tallest trees in the densest patches available.
