SUPERHIGH BY-PASS RATIO TURBOJET ENGINE

摘要

FIELD: aircraft industry. ^ SUBSTANCE: proposed superhigh by-pass ratio turbojet engine is provided with ring member arranged in lower part of outer pod in direction of flow made movable in axial direction, and conical central fairing arranged radially inside pod. Fairing is made on its outer surface of length L with angle of cone generatrix alpha=15-25° at outlet of nozzle of outer circuit with smooth transition to angle beta=0-15° at fairing cut at L/l=0.5-2.5 where l is axial displacement of ring member of outer pod. ^ EFFECT: reduced overall dimensions, weight and increased efficiency of turbojet engine. ^ 2 dwg
