STRUCTURAL BEHAVIOR MONITORING SYSTEM OF FLYING MACHINE WING Russian patent published in 2009 - IPC G01N3/02 G01M7/02 

FIELD: physics, measuring.

SUBSTANCE: invention concerns the control and measuring technics, in particular, a plane wing, and can be used for the control of structural behavior by gauging of vibrations of the cantilever of a wing immediately in flight. The device includes three accelerometres, the circuit changer of analogue signals for connection of accelerometres to analogue-digitizer, analogue-digitizer, three parallel registers, two adders, two storage devices, a control mean and the counter of updating of the address. Accelerometres are erected on the right, left cantilevers of a wing and at centre of masses of a flying machine for parametric evaluation of wing stiffnesses on an arcuation in the course of flight operation. Signals from accelerometres arrive on the device for record. On the earth there is an evaluation and an estimate of frequencies natural momental oscillations of the left and right wing. Effects of an estimate collect on set in group of service of resorts of the objective control for a statistical estimate of decrease in rigidity of a wing on an arcuation while in service.

EFFECT: structural behavior control possibility by gauging of vibrations of the cantilever of a wing immediately in flight and in reliability increase of the control.
