A device for picking up the jet of exhaust gases of a reactor of 371 and testing installation for the reactor of 371

摘要

The invention provides a device for collecting the exhaust gas jet of an aircraft reactor with orientable propulsion nozzle or with a gas jet orientable with respect to the longitudinal axis of said reactor, during ground testing of the latter, as well as a testing installation for aircraft reactors equipped with said device. The device comprises an external cylindrical jacket bell-mouthed at its end intended to be situated opposite the tested reactor and a cylindrical internal jacket, concentric to said external jacket and intended for straightening out the exhaust gas jet when this latter or the propulsion nozzle of the tested reactor has a slant with respect to the axis of said reactor.
