Abstract

This application belongs to the field of gas turbine engine anti -ice test technology, involving a device that controls the channel -type components in the ice wind cave to flow parameters.This device mainly includes an overflow device installed on the front end of the channel -type component. The overflow device includes a cylinder and ring component. The cylinder is installed on the intake port of the channel -type component.The inner wall of the rectifier, the ring component is installed on the outer wall of the cylinder, and the inlet of the inlet near the channel -type component is located.The flow speed of the type component.This application adopts the flow device control channel type component to flow the speed of flow speed, which can enable the ice -winded cave to be frozen and anti -ice test of small -sized channel components., Ensure the accuracy of the test results.

Description

technical field [0001] The application belongs to the technical field of anti-icing tests of gas turbine engines, and in particular relates to a device for controlling incoming flow parameters of channel-type components in an ice wind tunnel. Background technique [0002] The icing and anti-icing effect tests of gas turbine engine imported parts are one of the important verification activities in the engine design process. The anti-icing test of components should be carried out on ice wind tunnel equipment. There are generally two types of ice wind tunnels: free jet type and closed loop type. For the closed-circulation ice wind tunnel, when conducting the anti-icing test of channel-type components (for example, air intake casing), in order to ensure the incoming flow velocity, flow rate and surface water impact characteristics of the channel-type components, ice is usually The wind tunnel test section is directly connected to the channel-type component, that is, the mainstr...
