Analysis of Coordinated Steering Performance in Multi‑wheel Landing Gears

open access: yesTransactions 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.

Development of an energy-absorbing passenger seat for a transport aircraft [PDF]

open access: yes, 1985
Commercial air transport passenger safety and survivability, in the event of an impact-survivable crash, are subjects receiving increased technical focus/study by the aviation community. A B-720 aircraft, highly instrumented, and remotely controlled from

Effects of tooth heights on noise and vibration of mirrorlike ground gears.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1991
Spur gears with profile contact ratios ranging from 1.62 to 2.15 were mirrorlike finished to an accuracy of JIS 0 class using a CNC gear grinder designed and made by the authors. Elastic deformations of teeth and the resulting rotational errors of test gears were calculated, and then the amount and the starting point of profile modifications were ...

Flatfish herding behavior in response to trawl sweeps: a comparison of diel responses to conventional sweeps and elevated sweeps [PDF]

open access: yes, 2010
Commercial bottom trawls often have sweeps to herd fish into the net. Elevation of the sweeps off the seaf loor may reduce seafloor disturbance, but also reduce herding effectiveness.

Using tickler chains to promote more environmentally benign trawls in an Australian penaeid fishery

open access: yesAquaculture and Fisheries, 2023
There has been an increasing emphasis on reducing the environmental impacts of penaeid trawls by modifying their anterior sections. In one Australian estuary, this approach has culminated in a new generic trawl comprising a slightly smaller mesh size ...

Refining tickler chains for penaeid trawls

open access: yesAquaculture and Fisheries, 2022
Tickler chains are simple additions to the ground gears of benthic trawls that can improve the catches of some target species, albeit with considerable variability.
