METHOD OF LAND TRIALS OF OBJECTS OF AVIATION TECHNICS WHICH ARE EXPOSED TO ICING AND DEVICE FOR ITS REALISATION Russian patent published in 2009 - IPC G01M9/04 B64D15/20 

FIELD: physics, trials.

SUBSTANCE: inventions concern field of mechanical engineering and can be used in the aviation industry at carrying out of land trials of objects of the aviation technics which are exposed to an icing in vivo to operation. The method consists in imitation of requirements of operation with the help of airflow of the trials object by the organised and uniform water-airflow, created by airflow and system erected on an exit from a wind tunnel of the spraying devices in the form of atomisers. Thus maintenance of the uniform state of an airflow is provided with the ejecting air inlet on system of pipelines to the wind tunnel both sucking away an interface of an airflow and offtaking it in atmosphere, by heating of atomisers by hot air, and also turbulisation of airflow, by whirling of airflow in opposite directions by means of erected on an exit from a wind tunnel of two and more generators of vortexes. The device includes object of trials, a wind tunnel, airflow radiant, system of the spraying devices in the form of the atomisers erected in a wind tunnel, a main of delivery water and aerial working environments to atomizers, the mechanism of orientation of atomizers, radiants of the visible beams erected on atomizers for the control of their orientation. In addition on an exit from a wind tunnel it is erected two and more generators of vortexes. Besides, for heating of atomisers, for the purpose of icing exception in an operating time, delivery of hot air in the grooves executed on their surface is provided The control of a state of a water-airflow carry out by means of icing indicators translocated rather each other lengthways on stream, between wind tunnel and object of trials.

EFFECT: cutting of terms of trials by an exception of freezing of atomisers in the course of trials and mode adjustment, pinch of accuracy of effects of trials by making of real requirements of an icing in land requirements
