Study on Reducing Towing Drag by Varying the Shape and Arrangement of Floats and Gears
Applied Sciences, 2022 Many studies have been conducted with the aim of reducing fuel consumption by the fishing industry. We examined whether drag can be reduced by changing the arrangement of gears without requiring the development of new parts for the conventional float and

Preliminary calculation of the landing gear of a military training aircraft [PDF]
INCAS Bulletin, 2020 The paper presents a preliminary calculation method, which is easy to apply for pre-dimensioning the landing gear. Preliminary calculation of the landing gear includes estimating the loads on landing and determining the position of the nose landing gear ...

Landing Impact Load Analysis and Validation of a Civil Aircraft Nose Landing Gear
Aerospace, 2023 Landing impact load design is essential, but the process has rarely been fully described, and some designers have even neglected the differences between wheel-axle and ground-contact loads, as well as loads in the longitudinal direction, especially in ...

Impact of ground gear design on catch efficiency in demersal trawl fishery
Regional Studies in Marine Science, 2023 The choice of ground gear design in demersal trawls can significantly affect both catch composition and efficiency. The preference for a specific design depends on the fishing ground. In the North-Eastern Mediterranean, two types of ground gears, Single Line and Double Line are commonly used.

Influence of running-in on surface characteristics of efficiency tested ground gears [PDF]
Tribology International, 2017 The effect of running-in load (0.9 or 1.7 GPa) on surface characteristics of ground spur gears, and on their development during subsequent efficiency testing (FZG rig), is examined. The effect was confined to less than 10 ism depth. Micropitting was associated with surface asperities and their plastic deformation; higher running-in load gave more ...
