Problems solved by technology

In the actual flight of the aircraft, the air intake in the air inlet is huge, and it is often impossible to provide a matching air supply in the ground test environment
In addition, the configuration of the intake port is complex, and the engine in the exhaust section is expensive to use. Using the intake and exhaust interface scheme of a real aircraft has many shortcomings such as large test scale, large investment resources, and long construction period.
[0004] In order to facilitate installation, the annular radiator test environment in the prior art welds the annular radiator to the inlet and outlet pipes, and it is impossible to quickly replace the interface device, which is easy to cause loss to the test piece

Abstract

The invention provides an air inlet and outlet connector device for an annular radiator. The air inlet and outlet connector device comprises an air inlet connector assembly, an air outlet connector assembly and the annular radiator, the air inlet connector assembly comprises an air inlet inner barrel and an air inlet outer barrel, the air outlet connector assembly comprises an air outlet inner barrel and an air outlet outer barrel, the annular radiator is arranged between the air inlet connector assembly and the air outlet connector assembly, and the air inlet connector assembly and the air outlet connector assembly are fixed through a positioning connecting rod. According to the air inlet and outlet connector device for the annular radiator, the annular radiator can be rapidly replaced, the test environment building period is effectively shortened, the structure is simple, the performance is reliable, a movable connector is adopted, repeated utilization can be achieved, and the test requirement of the annular radiator is met at low cost.

Description

technical field [0001] The application belongs to the technical field of aircraft testing, and in particular relates to an air intake and exhaust interface device of an annular radiator. Background technique [0002] In the aircraft environmental control system, the contradiction between heat sink and heat dissipation is more prominent. As a section of the engine intake passage, the annular radiator can effectively use the cold resource of ram air and become an important part of the environmental control system. Therefore, a device with a matching annular radiator bleed air interface is required to ensure the normal operation of the system. [0003] The bleed air inlet of the annular radiator in the real aircraft is the aircraft intake, and the exhaust outlet is the engine. In the actual flight of the aircraft, the air intake in the air inlet is huge, and it is often impossible to provide a matching air supply in the ground test environment. Moreover, the configuration of ...
