Abstract : Gas flow in an aircraft bomb rack system is controlled by a variable orifice device, described in the patent application, that is insertable into system gas flow conduits in a manner that makes an opening through the device an integral part of the gas flow conduit. A portion of the device can be rotated to present varying amounts of transverse opening to the gas flow path. The rotatable portion is mounted on a positioning fixture that is keyed to a receptacle in the system housing and adapted to locate the device and maintain its position. Indexing marks are provided on the positioning fixture and on the rotatable portion that can be matched for any of a multiplicity of orifice openings and the components can be locked in any selected position.
