FIELD: aerodynamics.
SUBSTANCE: invention relates to experimental aerogas dynamics. Universal Eiffel working chamber of aerogas dynamics installation contains working chamber, model gas source at its inlet, and diffuser chamber at outlet. In working chamber there is partition forming auxiliary chamber. There are holes made in partition. One hole has diameter by 1.1÷1.3 times more than output nozzle diameter and is aligned with said nozzle. Holes on periphery of partition are equipped with plugs. During tests of aircraft models plugs are installed in holes on partition periphery. Test models holder attachment assembly is arranged in auxiliary chamber. During tests of rocket aft parts plugs in holes on periphery of partition are not set.
EFFECT: technical result of invention enables to conduct testing both models of missiles aft parts with nozzles of rocket engines and various aircraft models at minimum costs for reconfiguration and rearrangement of working part of installation elements.
