Abstract

This paper presents a calculation method for the design of three types of "wigglestrap" film-cooling construction, i. e. the square, the trapeze and the double circle arc constructions, which are applied to the flame tube of aeroengine. When the airflow distribution and the cooresponding airflow passage section areas are given, all parameters of the construction can be determined.
