Abstract

This article contains materials about defect of two-stage combustion chamber gas turbine engine occurringby high temperatures. The design of basic burner with blade swirler is shown. Improvement of burner byusing of the minimum of design changes is required. Ways by absence overheating of elements homogeneousburners combustion chambers is developed. Six variants of burners were selected for their studying. They weremade by machining bush of basic burner. This machining bush consists of increasing diameter of inner centerhole. It is having variant complete deleting bush and his changing on groove nozzle. Data of experimental worksto determine capacity eight types of burners as function of air pressure and formatting field of pressure on edgeof burner is presented. The research result of two types burner with groove nozzle for search new ways to solvetask of increasing reliability burners is shown. Optimal method tweaking burners for absence overheating swirlerwas selected.
