ABSTRACT:
The invention is a method of forming a multiple layer dielectric for use in a hot-film laminar separation sensor 21. The multiple layer dielectric substrate is formed by depositing a first layer 22 of a thermoplastic polymer such as on an electrically conductive substrate such as the metal surface 23 of a model 24 to be tested under cryogenic conditions and high Reynolds numbers. Next, a second dielectric layer 26 of fused silica is formed on the first dielectric layer 22 of thermoplastic polymer. A resistive metal film is deposited on selected areas of the multiple layer dielectric substrate to form one or more hot-film sensor elements 27 to which aluminum electrical circuits 28 deposited upon the multiple layered dielectric substrate are connected.
