Abstract : Fundamental problems encountered in combustion chambers and flame tubes of jet engines are discussed. It is recommended that the tightening force on combustion chamber flange bolts should not exceed 0.4 plus or minus 0.025 kgm. Fragment visual inspection of combustion chamber liners is recommended to prevent serious damage. A magnifying glass with a magnifying power of 5, the use of defectoscopy, and the use of ultrasound are recommended for inspections. Cracks found in flame tubes should be properly welded to increase their lifetime. (Author)
