FIELD: aero-hydrodynamic experiments. SUBSTANCE: films 1, 3, 7 of polyimide are subjected to treatment in aqueous solution of sodium bichromate 40.0 g/l, and sulfuric acid 400.0 g/l for the course of 3 to 5 min at temperature 60-80 C before metallization. After this film is rinsed with jet of distilled water. For protection against moisture upper surface of film of transducer is metallized with continuous layer. EFFECT: improved technological process. 2 cl, 1 dwg
