This paper presents an investigation into the gust response and wing structure load alleviation of a 200-seater aircraft by employing a passive twist 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 finite eleme
In order to cope with strengthened marine environmental regulations and to reduce fuel consumption, recently constructed vessels are equipped with an ultra-long stroke engine and apply engine de-rating technology.This was intended to improve propulsion efficiency by adopting a larger diameter propeller turning at a lower speed but also results in a
HTS 2G superconducting tapes without stabilizer are nova medical products for sale in arizona used for the construction of superconducting fault current limiters.The characteristics R =f(T) of the superconducting tape is essential for design of superconducting current limiters and analysis of their numerical models.The article presents the experime
Common reed fender two tone amp (Phragmites australis) is a widespread grass species that exhibits a high degree of intraspecific variation for functional traits along environmental gradients.However, the mechanisms underlying intraspecific variation and adaptation strategies in response to environmental gradients on a regional scale remain poorly
