Perforated fairings for landing gear noise control

, 2008
Landing gears of commercial aircraft make an important contribution to total aircraft noise in the approach configuration. Using fairings to shield components from high speed impingement reduces noise.

Study on impact of test loading on sudden extension performance of dual-chamber buffers

Hangkong gongcheng jinzhan
The 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 ...

Aircraft Nose Landing Gear Shimmy with Nonlinear Tyre Models

International Journal of Bifurcation and Chaos
In this study, an application of a nonlinear tire model is considered in the analysis of aircraft nose landing gear shimmy. An aircraft single-wheel nose landing gear system is used to analyze the shimmy stability, where the tire model is designed to account the nonlinear relaxation length by the two-degree-of-freedom model, as well as the nonlinearity

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.

Syphilis and ‘Sons of Empire’: The ‘Prostitute’ and Britain's Fighting Arm in Nineteenth ̵ Century Colonial Punjab

Gender &History, EarlyView.
ABSTRACT The British army in India took great care to provide European troops with facilities for sexual relations while anxiously managing venereal disease. Examining archival evidence, political debates and medical discourse from the nineteenth century, this article examines the colonial military enterprise of regulated prostitution in colonial ...
