METHOD AND DEVICE FOR INFLUENCING THE BODY LIMIT LAYER IN A FLOW

摘要

INFLUENCE ACCORDING TO THE PRINCIPLE OF ACTIVE MODIFICATION OF THE ORIGINAL MOVEMENT OF FLOWING PARTICLES CLOSE TO THE WALL. /P P THE PHYSICAL QUANTITY OF THE FLOW TO INFLUENCE AND USES CONTINUOUSLY BY PASSIVE SENSORS. CI AS ENTRY SIGNAL IN A REGULATION CIRCUIT WHOSE OUTPUT DELIVERS AN OSCILLATION SIGNAL TO BE INTRODUCED IN THE BOUNDARY LAYER BY AN ACTIVE OSCILLATION GENERATOR; THE DEVICE CONTAINS, INSIDE THE SURFACE 5 OF THE BODY 6 SURROUNDED BY THE FLUID, AT LEAST ONE PASSIVE SENSOR ELEMENT 1, 3, 4 AND AN OSCILLATION GENERATOR 2 WHICH COOPERATE WITH AN ANALYSIS AND REGULATION CIRCUIT 7 IN SUCH A WAY THAT FROM A FLOW QUANTITY CONTINUALLY MEASURED BY THE SENSOR, THEY GENERATE INSIDE THE SAID CIRCUIT A QUANTITY OF ADJUSTMENT WHICH EXERCISES, THROUGH THE OSCILLATION TRANSMITTER 2, AN INFLUENCE OF THE DESIRED SHAPE ON THE BOUNDARY LAYER. /P P THE INVENTION APPLIES IN PARTICULAR TO SUPPORTING WING PROFILES.
