GAS-TURBINE ENGINE COMBUSTION CHAMBER FLAME TUBE

摘要

FIELD: mechanical engineering. SUBSTANCE: proposed flame tube contains housing and segments furnished with two longitudinal and two cross ribs and secured on housing at least in one point. Cross shoulders are made on housing between which cross ribs of segments are located. Each longitudinal rib of segments is provided with projection. Projection on one rib of segment is located close to housing, and on other rib is remote from housing. Projections of adjacent segments are installed one over the other for contact, and fastening of segment to housing is made near projection remote from housing. EFFECT: improved efficiency of cooling owing to prevention of opening of butt joints between ribs of segments and housing and elimination of leakage of cooling air through said joints. 3 dwg
