Abstract
An object of the present invention is to provide a technique of enlarging a stable operating range of an intake in accordance with an operating condition of an engine without using a complicated control system so that a wide operating range of the engine can be covered. In an operation stabilization method for a supersonic intake according to the present invention, an enlarged duct between a cowl and a ramp of the intake is divided by a splitter plate such that an opening angle of the enlarged duct decreases. Further, in the operation stabilization method for a supersonic intake according to the present invention, when the duct is divided by the splitter plate, the splitter plate is disposed such that, from among a cowl side duct and a ramp side duct, cross-section variation in one duct, in which an effect of a flow is larger, is reduced within an allowable range of total pressure loss in the other duct.
