GAS-TURBINE ENGINE COMBUSTION CHAMBER

摘要

FIELD: mechanical engineering; aircrafts and ground plants. SUBSTANCE: combustion chamber of gas-turbine engine has number of flame tubes arranged in ring space formed by outer and inner housings, and stabilizers installed inside outlet of each flame tube. Each stabilizer is connected with corresponding screen pointed to combustion product flow and made from segment in the form of cone or hyperboloid of rotation whose vertex is placed in direction of flow, and screen surface directed to stabilizer forms a slot channel with the latter. Side walls of stabilizer are arranged at an acute or right angle relative to each other. Rear wall of stabilizer coincides with cross section of flame tube, and one of side walls of at least four stabilizers is parallel to radial plane of flame tube passing through axis of combustion chamber. EFFECT: enhanced reliability and increased service life of combustion chamber at reduced overall dimensions due to complete combustion of fuel and reduced times during which combustion products are in maximum temperature zones. 7 dwga
