Title:
THRUST RESERVOIR OF SPECIFIC CONTOUR FOR GAS TURBINE ENGINE AND NOZZLE SILENCER WITH LOBE
Document Type and Number:
Japanese Patent JP3289142
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To reduce engine noise to a moderate degree by making a blocker door of a specified contour form adjacent to a nozzle with a lobe, and forming an outer surface with a substantially continuous lobe, when the blocker door of the specific contour form is put in a storing position.
SOLUTION: Rear parts 40 of blocker doors 34, 36 of a specific contour form are formed, corresponding to the form of the front of a nozzle 32 with a lobe in a storing position, where the blocker doors 34, 36 of the specific contour form and the front of the nozzle 32 with a lobe overlap. Thus, when the blocker doors 34, 36 are put in the storing position, the rear parts 40 of the blocker doors 34, 36 with a lobe or of the specific contour form are aligned with the nozzle 32 with a lobe and adjacent thereto, to form an outer surface with a substantially continuous lobe. This outer surface is formed aerodynamically, so that the nozzle 32 with a lobe accelerates mixture of ambient air and engine exhaust, and mixing or noise reduction effect can be provided.
