LABEL SENSOR FOR AERODYNAMIC ANGLE AND AIR SPEED Russian patent published in 2012 - IPC G01P5/14 

FIELD: physics.

SUBSTANCE: device has an ion label generator, a system of receiving electrodes, a channel for detecting ion labels and a measuring circuit for generating output signals. The system of receiving electrodes is in form of circular metal plates lying equidistant on a circle with the centre at the point of generation of ion labels and are placed directly under the opening in the metal plate - "mask", which is mounted on a dielectric plate, where the receiving electrodes are connected to inputs of preamplifiers of the channel for detecting ion labels and are merged into autonomous modules, having a screening housing. Outputs of the preamplifiers are connected through analogue switches (commutator switches) and adders to inputs of differential amplifiers of the channel for detecting ion labels.

EFFECT: wider measuring range for the aerodynamic angle, ensuring high aerodynamic angle resolution without increasing the number of receiving electrodes and size of the system of receiving electrodes, possibility of simultaneous measurement of the value and the direction angle of the air velocity vector of aircraft without putting protruding aerometric receivers into the incoming air stream.
