The correct choice of a propulsion system for UAVs, especially for small and medium-size classes, is a difficult task. Despite a number of significant advantages of microgasturbines (MGT) compared with the electric motors and internal combustion engines, first have a very low overall efficiency of the order about 17%, which was caused by low cycle parameters and low propulsion efficiency of modern MGT. So, improvement of MGTs efficiency leads to better overall performance of UAVs and carrying out of further experiments and developing new approaches to MGT is very important.</p>Boundary layer theoryexperimental aerodynamicslow Reynolds numbersmicrogasturbinesoverall efficiencyunmanned aerial vehiclewater channelwind tunnelАэродинамическая трубабеспилотный летательный аппаратводный каналмигрогазотурбинный двигательнизкие числа Рейнольдсаобщий коэффициент полезного действиятеория пограничного слояэкспериментальная аэродинамика
