Title:
AFTERBURNER AND AIRCRAFT ENGINE
Document Type and Number:
WIPO Patent Application WO/2015/166921
Kind Code:
A1
Abstract:
The present invention improves the durability of an afterburner (25) and yet suppresses a reduction in the engine efficiency of an aircraft engine (1). A ring-shaped cooling channel (35) through which cooling air (CA) flows is formed between the outer peripheral surface of a liner (31) and the inner peripheral surface of a rear duct (29). A plurality of cooling holes (37) for blowing the cooling air (CA) along the inner peripheral surface of the liner (31) are formed penetrating the liner (31). A ring-shaped annulus flame-holding member (51) on the inner peripheral surface of the liner (31) is provided concentrically with respect to a plurality of radial flame-holding members (47). The inner diameter of the annulus flame-holding member (51) decreases in the downstream direction. The annulus flame-holding member (51) functions as a throttle ring which throttles the flowing of a main flow of a mixed gas inside the liner (31).
