In the course of the tests it was established that the pipes formed by flexible pushing through adie with the internal pressure of the filler and those produced by flexible expansion with elastic medium havecyclic longevity exceeding the resource of an airframe.</p>Life testtubular partslongevitypulsating pressureИспытания на ресурструбчатые деталидолговечностьпульсирующее давление
