Among the variety of pilotless aircrafts (BPLA) of different types most distribution was got by complexes battle-fields (MINI-BPLA) which execute tasks on purpose in a radius a 2...15 km These vehicles are usually equipped a power-plant in which an airscrew is driven to the action an electric engine. An aviation market offers the enormous amount of vehicles of this type on this time. Their producers, promoting a product, declare certain aircraft performance descriptions. How after these descriptions to estimate, even approximately, technical perfection of standard of traditional aerodynamic arrangements is the article of this article.
