In this article, the object of research is various layouts of unmanned aerial vehicles with a small turbojet engine using an ejector thrust magnifier. The author develops aerodynamic layouts of unmanned aerial vehicles taking into account the required size and operating speed range, determines the optimal aerodynamic scheme, performs a numerical calculation of the engine operation with an ejector thrust booster, optimizes design parameters in the XFLR5 and ANSYS software packages.
Currently, unmanned aerial vehicles of various tactical and technical parameters, sizes and masses are being developed. The engines will be improved increasing efficiency and improving the characteristics: thrust, efficiency and mass. The rapid development of unmanned aerial vehicles is due to the advantages they have, for example: the absence of crew members eliminates the risk of human losses, the ability to perform maneuvers with an overload exceeding the physical capabilities of pilots, as well as the absence of a crew fatigue factor. The cost of unmanned aerial vehicles has been reduced, and lower operating costs allow for the mass production of inexpensive but efficient aircraft.
The article presents graphs of changes in the aerodynamic characteristics of the considered layouts of unmanned aerial vehicles, the results of numerical calculation during the operation of the engine in flight with an ejector thrust booster, a comparison of the results obtained, as well as options for optimizing design parameters, which is the main purpose of the study in this work.
