System for sealing variable gaps for scale models tested in an aerodynamic tunnel

摘要

The system for sealing for variable spaces comprising packing means (3) for at least partially packing a space (4) between two pieces (1, 2) of a model, characterised in that at least a first piece (1) of the model presents, on its side facing a second piece (2) of the model, at least one recess (5) with a front end (5a) open and a back wall (5b), with the packing means, comprising an elastic and flexible packing body (3), being located in the front end (5a), and the back wall (5b) containing a set of spring elements (6, 7) among which are to be found coil springs or elastic strips, at least partially compressed by the packing body (3) and which push the latter against the surface of the second piece (1b) of the model.
