Abstract

The invention provides an aero-engine turbine blade air mass flow testing device. The testing device comprises an inlet valve, a pressure gauge, a filter, a self-operated pressure maintaining valve, a main path adjustment valve, a bypass fluid passage provided with a bypass adjustment valve, at least two multipled measuring by-paths, a temperature sensor, a pressure sensor, a blade clamp and a worktable. Each measuring by-path is provided with a stop valve and a flowmeter from an inlet end to an outlet end in sequence, and the flowmeter of each measuring by-path has different measuring ranges. The provided aero-engine turbine blade air mass flow testing device is used for making testing the conditions of film holes of turbine blades and internal fluid passage processing convenient, and provides reference for choosing installed blades.

Description

technical field [0001] The invention belongs to the field of aero-engine non-standard parts, in particular to an aero-engine turbine blade air flow test device. Background technique [0002] According to the development requirements of the engine turbine blade equipment, it is necessary to conduct an air flow test on the measured blade, that is, to measure the air mass flow through the blade under the test pressure, and to check the air film hole of the blade by measuring the air flow of the turbine blade air film hole and the flow channel The conditions and internal flow channel processing conditions provide a reference for the selection of installed blades. This requires the use of air flow test equipment. At present, the air flow test device for measuring aeroengine turbine blades is a kind of fixture, and the connected pipeline needs to be fixed in a specific test room, which is inconvenient to carry, takes up a lot of space, and the measurement range cannot be adjusted...
