Established Numerical Techniques for the Structural Analysis of a Regional Aircraft Landing Gear

Advances in Materials Science and Engineering, 2018
Usually during the design of landing gear, simplified Finite Element (FE) models, based on one-dimensional finite elements (stick model), are used to investigate the in-service reaction forces involving each subcomponent.

The Art of Reception: Field Visits as Microcosms for Development Interventions of Non‐Governmental Organisations in Uganda

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 ...

Dynamics of Oleo-Pneumatic Landing Gear Systems for Carrier-Based Unmanned Aerial Vehicles

Aerospace
This paper presents a comprehensive analysis of the dynamics and design of oleo-pneumatic shock absorbers for the landing gear of carrier-based Unmanned Aerial Vehicles (UAVs). Carrier-based operations impose unique challenges due to high-impact landings,

Individual movement modeling expands the power of migratory species observations: North Atlantic right whale case study

Limnology and Oceanography: Methods, EarlyView.
Abstract Understanding a population's distribution depends on observing the presence and movement of individuals throughout their range. For highly mobile marine species, these observations typically rely on high effort monitoring programs. Tracking enough individuals to understand trends in movement behavior is not always logistically feasible, and ...

Analysis of Coordinated Steering Performance in Multi‑wheel Landing Gears

Transactions of Nanjing University of Aeronautics and Astronautics
During aircraft ground steering， the nose landing gear （NLG） tires of large transport aircraft often experience excessive lateral loads， leading to sideslip. This compromises steering safety and accelerates tire wear.

Effects of preservatives and poisons on the elemental and isotopic composition of freshwater particulate organic matter

Limnology and Oceanography: Methods, EarlyView.
Abstract Sediment traps, often used in tandem with preservatives or poisons, are widely used for the collection of particulate organic matter (POM), providing insight into the source to sink mechanisms that shape major biogeochemical cycles and sedimentary carbon sequestration.

Research Study Concerning the Structural Design of a Drone Using 3D Print Technology

Macromolecular Symposia, EarlyView.
ABSTRACT The frame of a drone serves as support to hold in place all the key components of the drone, such as the battery, controller board, motors, and all the modules needed for different projects. In the industry, the drone frame is CNC machined from a block of material, or in some cases it is made of composite materials, carbon fiber, and ...
