Device for detecting separation and assembly for such a device
A device for detecting separation in an aerodynamic or hydrodynamic profile having a one-piece structure with a flexible and deformable strip extending between the first end and the second end. The second end of the strip being free. A mounting plate configured to be attached to the profile. The mounting plate includes the first end of the flexible and deformable strip. The mounting plate also includes a circuit board and at least one separation sensor having a magnet generating an electrical signal which indicates a separation value.
1 . Device to detect separation in an aerodynamic or hydrodynamic profile, comprising a one-piece structure comprising:
a flexible and deformable strip made from a silicone material extending between a first end and a second end, the second end being free;
a mounting plate configured to be attached to the aerodynamic or hydrodynamic profile, the mounting plate comprising the first end of the flexible and deformable strip, a circuit board and at least one separation sensor comprising a magnet, the magnet generates an electrical signal indicative of a separation value along three orthogonal axes;
wherein the circuit board attached to the mounting plate transmits the electrical signal by a radio transmission system or a wired connection; and
wherein said at least one separation sensor is non-intrusive and detects a flow separation without disrupting a flow and without increasing drag.
2 . The device of claim 1 , further comprising a battery positioned internally or externally to the device, the battery serving as a power supply and connected to the circuit board.
3 . The device of claim 1 , wherein the one-piece structure comprises three parts: a first part comprises the flexible and deformable strip, a second part comprises the mounting plate, and a third part comprises a protective shell covering the mounting plate.
4 . The device of claim 1 , wherein the separation sensor utilizes principles of Hall effect electromagnetism or inductive eddy current.
5 . The device of claim 1 , wherein the flexible and deformable strip moves from a lowered position to a raised position.
6 . The device of claim 1 , wherein the silicone material of the flexible and deformable strip has a Shore value between 20 and 100.
7 . An assembly comprising a plurality of devices of claim 1 .
8 . The assembly of claim 7 , wherein each device comprises a battery positioned internally or externally to said each device, the battery serving as a power supply and connected to the circuit board of said each device.
9 . The assembly of claim 7 , wherein the one-piece structure of each device comprises three parts: a first part comprises the flexible and deformable strip, a second part comprises the mounting plate, and a third part comprises a protective shell covering the mounting plate.
