Computational Evaluation of Aerodynamic Loading on Retractable Landing-Gears
Aerospace, 2020 Computational fluid dynamics is employed to evaluate the mean aerodynamic loading on the retractable landing-gears of a regional transport commercial aircraft. The mean turbulent flow around simplified landing-gear systems including doors is simulated by

Experimental Investigations on the Possibility to Apply the Corrugated Sheet Metal Used in the Past with Junkers Aircraft to Reduce Noise for Future European Aircraft. Other Noise Reduction Experiments for Future European Aircraft [PDF]
INCAS Bulletin, 2018 This paper shows that corrugated skin used in the past with Junkers aircraft to increase the fuselage and wing rigidity can lead to noise reduction for future European aircraft. If the pressure side of wing which is placed above the engine is corrugated,

Shimmy analysis of light weight aircraft nose wheel landing gear
Vibroengineering Procedia, 2022 This paper presents mathematical modeling and analysis of shimmy oscillations for a light weight airplane single wheel nose landing gear. Shimmy is a self-excited oscillation which occurs usually on the nose wheel landing gear assembly during ground maneuvers which is governed by the dynamic characteristics of the landing gear and tires.

Lack of capture‐induced mortality of neonates associated with variation in handling protocols
Wildlife Society Bulletin, EarlyView.We found that handling metrics (e.g., handling time, number of collectors, and age at capture) had limited or no influence on the survival of neonatal mule deer, desert bighorn sheep, and Rocky Mountain bighorn sheep within the first few days of life. Furthermore, we found that handled mule deer and Rocky Mountain bighorn neonates were recruited at a ...
