Abstract
Изобретение относитс к испытани м и оценке работоспособности, например, деталей летательных аппаратов, винтов и т. п. Цель изобретени - приближение условий испытани к реальным услови м изнашивани деталей летательных аппаратов. Способ реализуетс следующим образом. Вращают образец, прикладывают к нему изгибающий момент и одновременно изнашивают потоком газовой среды, который подают либо попутно, либо навстречу движению изнашиваемой поверхности. 2 ил.The invention relates to testing and evaluating the performance of, for example, aircraft parts, propellers, etc. The purpose of the invention is to approximate test conditions to actual wear conditions of aircraft parts. The method is implemented as follows. A sample is rotated, a bending moment is applied to it, and at the same time it is worn by a stream of gaseous medium, which is supplied either along the way or towards the movement of the wear surface. 2 Il.

Изобретение относитс к испытани м и . оценке работоспособности, например деталей летательных аппаратов, винтов и т.п.The invention relates to tests and. performance assessment, such as parts of aircraft, screws, etc.
Цель изобретени - приближение условий испытаний к реальным услови м изнашивани деталей летательных аппаратов.The purpose of the invention is to bring the test conditions closer to actual wear conditions of aircraft parts.
На фиг. 1 показана принципиальна схема взаимодействи потока газовой среды с образцом; на фиг. 2 - сечение А-А на фиг. 1.FIG. 1 shows a schematic diagram of the interaction of the flow of a gaseous medium with a sample; in fig. 2 is a section A-A in FIG. one.
Устройство дл реализации способа содержит приспособление (не показано) дл подачи потока 1 газовой среды, длинномерный образец 2, установленный с возможностью вращени в опорах 3, приспособление (не показано) дл приложени изгибающего момента за счет силы Q.A device for implementing the method comprises a device (not shown) for supplying a stream of 1 gaseous medium, a long sample 2 mounted rotatably in the supports 3, a device (not shown) for applying a bending moment due to the force Q.
Способ реализуетс следующим образом .The method is implemented as follows.
Вращают длинномерный образец 2, прикладывают к нему изгибающий момент и одновременно изнашивают потоком газовой среды с абразивными и/или жидкими частицами, которые подают либо попутно, либо навстречу движению изнашиваемой поверхности по касательной к ней.Rotate the lengthy sample 2, apply a bending moment to it and at the same time wear it with a stream of gaseous medium with abrasive and / or liquid particles, which are served either along the way or against the movement of the wearing surface tangentially to it.
Пример. Изнашивали образец 2 диаметром 20, изнашиваема поверхность была выполнена вогнутой (радиус кривиз0Example. Sample 2 with a diameter of 20 was worn, the wear surface was made concave (radius of curvature
ны R 40). При вращении образца 2 возникал циклически измен ющийс момент (частота 100 Гц), а на поверхности образца напр жени достигали 200-400 МПа. Одновременно на образец 2 подавали воздух, содержащий частицы пыли. Услови подачи потока 1 по первому варианту навстречу (поток 2 или 2) движению поверхности образца 2, а по второму варианту попутно (поток 2) движению поверхности образца 2.R 40). When sample 2 was rotated, a cyclically varying moment (frequency of 100 Hz) appeared, and the voltage on the sample surface reached 200-400 MPa. At the same time, air containing dust particles was supplied to sample 2. The flow conditions of flow 1 in the first embodiment meet (flow 2 or 2) to the movement of the surface of sample 2, and according to the second option in passing (flow 2) to the movement of the surface of the sample 2.
