An optimal choice of a power plant is an important problem when ultra-light unmanned aerial vehicle work out. Aerodynamic experiment is a significant part of this problem solution. Aim of experiment is to determine throttle and speed performances of a power plant, also efficiency coefficient of propeller for different modes. A technology of execution of the experiment is considered in the paper and the results are shown: throttle performances on the thrust of the internal combustion engine MDS0.78 with 362mm×148mm propeller; throttle performances on the thrust and power of the internal combustion engine MDS1.48 with 17″×8″ propeller; speed performances on the thrust and power of MDS1.48 motor with 16″×10″ propeller. Values of an efficiency coefficient of 16″×10″ propeller are gotten for flow speed 0, 10.4 and 14 m/sec when 6000 rpm. A comparison of experimental and accessible theoretical results [1, 2, 3, 4] is given. The results of experiment can be useful when design and manufacture ultra-light unmanned aerial vehicle to provide an optimal combination of profiles of the load carrying surfaces and elements of power plant.
