Pitot-static tube tester system

Claim 1

A pitot-static tube tester system for use with a pitot-static tube to be tested, wherein said pitot-static tube has one pitot pressure passageway with an inlet and two static pressure passageways with an inlet in each said static pressure passageway, said pitot-static tube tester system comprising: a. a source of pitot pressure in communication with said inlet of said pitot pressure passageway of said pitot-static tube, wherein a pitot pressure flow emanates from this source; b. two sources of static pressure, with one of these sources in communication with the inlet of one of said static pressure passageways of said pitot-static tube, and with the other of these sources in communication with the inlet of the other static pressure passageway of said pitot static tube, wherein a static pressure flow emanates from each of these sources; c. an integrated pitot-static tube adapter assembly removably fitted over, releasably secured to, and selectively operably associated with said pitot-static tube, wherein said assembly includes: a hollow external member made of steel and cadmium plated, with this member having one pitot pressure opening, two static pressure openings, an entrance opening, and an internal surface, wherein this member is removably fitted over said pitot-static tube such that the pitot pressure opening of this member and the pitot pressure passageway inlet of said pitot-static tube are in communication, and such that the two static pressure openings of this member are in communication with a different one of the two static-pressure inlets of said pitot-static tube; a hollow sleeve-like subassembly which is disposed internally of said hollow external member and which includes a plurality of four aligned hollow aluminum spacers having end flanges in contact with said internal surface of said hollow external member, whereby annular spacers are formed between said spacers and said internal surface of said hollow external member, with two of said spacers each having two openings therein which are in communication with their corresponding annular spacers and which are also in communication with their respective static pressure openings of said hollow external member, with another of said spacers disposed such that its hollow portion is in communication with said pitot pressure opening of said hollow external member; a hollow end member connected to and in communication with said entrance opening in said hollow external member, wherein said end member is threadedly movable inwardly of said hollow external member; and a plurality of five hollow rubber seals interspersed between and among said plurality of four aligned aluminum spacers; whereby said hollow external member and said hollow-sleeve like subassembly define and separate said three pressure flows from each other; and whereby when said end member is moved inwardly of said hollow external member, said hollow rubber seals are compressed and become enlarged, thereby said enlarged seals contact and hold said pitot-static tube, and thereby releasably secure said adapter assembly to said pitot-static tube.
