FIELD: aeronautical engineering. SUBSTANCE: vibratory ice detector includes vibrator whose sensitive element is made in form of flexible diaphragm, air intake mounted on vibrator housing, working chamber located between air intake and sensitive element with outlet ports on side surface. Outlet of air intake having acute angle end surface in form knife forms circular clearance with plane of sensitive element. Outlet of air intake has such diameter that circular clearance passes above plane at maximum amplitude of vibrations of flexible diaphragm. EFFECT: enhanced reliability. 3 dwg
