ABSTRACT:
A system for testing, on the ground, an aircraft pitot-static pressure tube, its pitot and static pressure passageways and inlets, and the air pressure-sensitive flight instruments attached to the pitot-static pressure tube. The system includes a hollow adapter assembly into which the tip of the pitot-static pressure tube is inserted. When the tip is as far as it can go into the hollow adapter system, the pitot and static pressure inlets of the pitot-static tube are automatically in communication with their respective corresponding outlets in the hollow adapter assembly, irrespective of the orientation either of the pitot-static tube or of the hollow adapter assembly. This is accomplished with the use of a plurality of hollow spacers, internal of the hollow adapter body, which have flanged ends and form annular chambers that are intermediate of and in communication with the inlets and with the respective outlets. The hollow adapter assembly is releasably secured to the pitot-static tube by the use of rubber seals which, when compressed, expand, contact the tube, and hold it.
