A peculiar characteristic that comes from the results is a lift-enhancement derived from the unusual shape of the dragonfly airfoil. The book considers the current research, conducted at the Department of Aerospace Engineering at the University of Michigan, USA, and analyzes a corrugated airfoil in gliding flight at different Reynolds numbers and for various angles of attack in unsteady state simulations. The primary focus of this book is a computational study of the aerodynamic characteristics of a dragonfly aerofoil. With the advent of the micro air vehicles (MAVs), vehicles with a maximal dimension of 15 cm or less and a flight speed of 10 m/s, the aerospace engineering community started to conduct studies about the aerodynamic characteristics of the flight of birds, bats and insects. Low Reynolds number aerodynamics is characteristic of the flight of many natural and man-made flyers. From past studies dragonfly wings, compared with a flat plate or a conventional smooth airfoil, highlighted better performance in term of lift and drag.

Порядок перевода слов в атрибутивных группах может быть различным и определяется по смыслу, например: Low empera ure physics – физика низких температур.5.Выделение атрибутивной группы 1 2 облегчается наличием различных суффиксов существительного 2 (-er (-or), -me , -io (- io , -sio )), например: We compare he levels of machi e vibra io s wi h biological sys ems.6.Наличие явного сказуемого (is, are, was, were, have, had, has, mus , ca , may) – облегчает поиск атрибутивной группы 1 2, выступающей в функции подлежащего, например: Sou d waves are a alyzed by he compu er every o e-hu dred h of a seco d.7.Атрибутивная группа 1 2 может входить в состав подлежащего и вводиться при помощи различных предлогов (of, a , i ), например: A ew ype of laser beam has bee developed by Byelorussia scie is s, где, 1 2 /laser beam/, стоящее перед явным сказуемым «has bee developed», вводится в группу подлежащего при помощи предлога rai .
