Abstract
A change-over arrangement for an integrated turboramjet engine has a guide ring which can be displaced in the axial direction and an annular cone which can be displaced against the guide ring. In the turbo-operation, the annular cone is in its front position and the guide ring is in its rear position closing off a ram air inlet duct, and in the ramjet operation, the annular cone, in its rear position, closes off the turbo-inlet duct, and the guide ring opens up the ram air inlet duct. As a result, a low-loss introduction of the air current can take place into the turbo-inlet duct or into the ram air inlet duct, without, at the same time, requiring disadvantageous enlargements of the diameter of the outer casing of the engine.
