Problems solved by technology

Ice wind tunnels usually have high operating costs, take up a lot of space, and are difficult to independently develop, which is not conducive to basic icing tests; high and low temperature boxes and environmental laboratories can adjust the temperature in a confined space and conduct low temperature tests, but they cannot simulate wind speed And freezing cloud cloud environment, can not simulate the aircraft icing process and ice shape under real conditions

Abstract

The invention discloses a freezing cloud icing temperature-control simulation laboratory suitable for small- and medium-sized aircrafts; the freezing cloud icing temperature-control simulation laboratory comprises an inner building for receiving a test article, a spraying system for producing water spray, a power fan system for producing an air flow that delivers the water spray to the test article, and a refrigerating and heat exchange system used for adjusting inner temperature of the inner building and which may allow the test article to be in a low-temperature environment. The test article is a scaled-down model of an aircraft anti-icing system component. The freezing cloud icing temperature-control simulation laboratory can simulate low temperature, air speed and icing cloud and mist at the same time, is high in cost performance and simple in structure, has large available space, and is important to the experimental validation and technical research for anti-icing / deicing systems.

Description

technical field [0001] The invention belongs to the technical field of aircraft testing, in particular, the invention relates to a freezing cloud icing temperature control simulation laboratory suitable for small and medium-sized aircraft. Background technique [0002] The icing phenomenon, because it changes the aerodynamic shape of the aircraft, has an important impact on the performance, stability and control of the aircraft, and is extremely harmful to the safe flight of the aircraft. The aircraft icing test in the climate laboratory is an effective method to verify the function of the aircraft anti-icing / de-icing system, which is of great significance to flight safety. [0003] Domestic research on aircraft icing started relatively late, mainly on water droplet impact characteristics and numerical simulation of wing surface icing process. There are relatively few icing tests, mainly ice wind tunnel tests, and there is no general-purpose small and medium-sized It is a p...
