Nekrasov - Hydraulics For Aeronautical Engineers - Fundamentals and Applications","","Boris Nekrasov’s Hydraulics for Aeronautical Engineers presents a structured foundation of hydraulic science and its industrial use in aircraft systems. The text explains hydrostatics, relative rest of a liquid, and the core equations governing hydraulic motion. It develops flow through pipes, laminar and turbulent regimes, and analyzes local features and minor losses. Worked problems, diagrams, and engineering examples connect theory with practical calculation for aircraft hydraulic components.",{"@graph":14,"@context":72},[15,34,55],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/research-report/","Research
