Aeral injector for combustor of small unmanned aircraft – results of investigation

The conception of the construction of the fuel spray injector for a turbo engine of a small unmanned aircraft is proposed in this paper. The work out of the injector model made in rapid prototyping method is shortly presented. Methods of the injector investigation were described. The results of the injector flow parameters and macrostructure parameters investigation were presented and discussed. They were used to formulate the main conclusion connected with the relation between the injector construction, the injector feeding parameters and spray parameters.
