Influence of Variable Side-Stay Geometry on the Shimmy Dynamics of an Aircraft Dual-Wheel Main Landing Gear [PDF]

, 2013
Commercial aircraft are designed to fly but also need to operate safely and efficiently as vehicles on the ground. During taxiing, take-off, and landing the landing gear must operate reliably over a wide range of forward velocities and vertical loads ...

Community science datasets identify the spatial occurrence and hotspots of flapper skate (Dipturus intermedius)

Journal of Fish Biology, EarlyView.
Abstract The flapper skate, Dipturus intermedius (Parnell, 1837), is a large‐bodied, slow‐growing and late‐maturing, Critically Endangered elasmobranch with a constrained population distribution. Here, we use two longitudinal community science datasets to investigate the occurrence of flapper skates in Irish waters. The two datasets are as follows: the

Uncertainty Quantification in Planning Aircraft Ground Movement Operations With Towbarless Robotic Tractors

International Journal of Robust and Nonlinear Control, Volume 36, Issue 5, Page 2542-2556, 25 March 2026.
ABSTRACT This article addresses the problem of quantifying the uncertainty in planning aircraft ground movement operations using towbarless robotic tractors taking into account the inherent uncertainties of the problem, specifically, the uncertainties in the weight of the aircraft and in the rolling resistance of the wheels of the main landing gear ...

Stress Distribution Analysis using ANSYS of the Nose Landing Gear of STOL Aircrafts Considering Runway Gradient: A Simulation Study

Orchid Academia Siraha, 2023
Landing gear failures are a major cause of aircraft failures because they are an integral part of the aircraft's development. According to the Federal Aviation Administration (FAA), 50% of all aircraft failures occur during take-offs and landing.

Friction Shock Absorbers and Reverse Thrust for Fast Multirotor Landing on High‐Speed Vehicles

Journal of Field Robotics, Volume 43, Issue 2, Page 1068-1090, March 2026.
ABSTRACT Typical landing gears of small uninhabited aerial vehicles (UAV) limit their capability to land on vehicles moving at more than 20–50 km/h due to high drag forces, high pitch angles and potentially high relative horizontal velocities. To enable landing at higher speeds, a combination of lightweight friction shock absorbers and reverse thrust ...

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.

Length‐Based Assessment of the Seven Most Commonly Caught Coral Reef Fish Species to Support Improve Management of Small‐Scale Fisheries in Southwest Madagascar

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT The status of most fish stocks in Madagascar remains poorly documented. Given their importance for food security and livelihoods, it is necessary to define management measures with reliable data. This study applied a length‐based Bayesian biomass (LBB) estimation method for analysing the fisheries' representative length‐frequency data of seven

When property becomes rent

American Ethnologist, Volume 53, Issue 1, Page 45-56, February 2026.
Abstract For millions of working‐class Mexicans, property has turned into rent. This transformation has fundamentally dislocated social reproduction in Mexico by eroding households’ ability to envision themselves as holders of patrimony and as lasting social formations. To understand how and to what effect property turned into rent, we must look to the

Study on the Fast Extension Mechanism of Double-Cavity Shock Absorber with High-Pressure Piston

International Journal of Aerospace Engineering, 2021
Double-cavity shock absorber with high-pressure piston is the core component of the nose landing gear of the carrier-based aircraft, and its fast-extension performance seriously affects the safety of the catapult-assisted takeoff. The design of a carrier-

Application of Topology Optimization Method for Unmanned Aerial Vehicle Nose Landing Gear Fork

Journal of Polytechnic, 2022
Landing gear is one of the most important components of the aircraft. Among the tasks of the landing gear is to carry the loads coming on the aircraft, damping the impact at the time of landing and allow the aircraft to taxi. The landing gear consists of
