Adapter for connecting a pressure line to the perforated surface of a model to be tested in the wind tunnel

摘要

To measure the pressure distribution at an airplane model and the like, the surface of the model is provided with a number of holes (11) . An adapter (25) of elastomeric material adapted to be joined via a pressure duct (24) to a testing means is placed on each hole (11). A plurality of connecting hoses (13) extending out of the model (10) are joined to a measuring point selector (14). Each adapter (25) contains a self-adhesive flange by which the adapter may be sealingly mounted quickly and by simple means to a measuring bore.
