GUST ALLEVIATION OF A LARGE AIRCRAFT WITH A PASSIVE TWIST WINGTIP

Gust Alleviation of a Large Aircraft with a Passive Twist Wingtip

This paper presents an investigation into the gust response and wing structure load alleviation of a 200-seater aircraft by employing a passive twist 2.75x100 wingtip (PTWT).The research was divided into three stages.The first stage was the design and analysis of the baseline aircraft, including aerodynamic analysis, structural design using the fin

Extracellular DNA is essential for maintaining Bordetella biofilm integrity on abiotic surfaces and in the upper respiratory tract of mice.

Bacteria form complex and highly elaborate surface adherent communities known as biofilms which are held together by a self-produced extracellular matrix.We have previously shown that by adopting a biofilm mode of existence in vivo, the gram negative bacterial pathogens Bordetella bronchiseptica and Bordetella pertussis are able to efficiently colo
