The Study of Air Flows for an Electric Motor with a Nozzle for an Unmanned Flying Platform
Authors: , ,
Abstract: The subject of this article is the analysis of unit parameters of the electric motor placed on the rotorcraft carrying frame in the aspect of the process implemented in this type of drive unit. The main purpose of this work is to carry out tests of the air flow of the drive unit in the range of changes in the unit thrust depending on the operating conditions of electric motors, based on numerical analyses using the finite element methods, through which the analysis of the nozzle installed under the engine was performed. To this end, the course of changes in calculated parameters characterizing aerodynamics along flow channels of engines implemented in unmanned aircraft vehicles was analyzed. In addition, created mathematical models describing physical phenomena within the simulation domain (study area) were considered. In the final part of the article, on the basis of the above and the obtained results of simulation studies, practical conclusions were formulated.
