Simulation system for ice-formation condition on ground

Abstract

The invention provides a simulation system for an ice-formation condition on a ground, and the simulation system is used for verifying the capacities of preventing / removing ice of tested pieces in an outdoor low temperature environment. The simulation system of the invention comprises a spraying device, a water supplying device, a gas source device, a wind source device and a measurement-control device, wherein the spraying device contains a spraying rod with a nozzle and an affiliated pipeline of the spraying rod, and the affiliated pipeline contains an air inlet pipe and a water inlet pipe; the water supplying device is communicated with the water inlet pipe, and delivers water through purification treatment to the nozzle; the gas source device is communicated with the air inlet pipe, and delivers high pressure air through purification treatment to the nozzle; the wind source device which simulates a wind tunnel delivers uniform and stable airflow to the spraying device; and the measurement-control device controls the whole simulation system, and can display the test parameters in real time. The simulation system for the ice-formation condition on the ground of the invention can simulate the meteorological condition of freezing fog on the ground in the outdoor low-temperature environment, produces water spray with adjustable liquid water content and water droplet diameter, and provides strong guarantee for verifying the capacities of preventing / removing ice of such as a short cabin of an airplane.

Description

technical field [0001] The invention relates to a ground icing condition simulation system, in particular to a ground icing condition simulation system for verifying the anti-icing / deicing ability of a test piece in an outdoor low temperature environment. Background technique [0002] During the airworthiness certification process of large civil aircraft, Article 1093(b)(2) of FAR25 and CCAR25 requires the applicant to show to the Authority that the nacelle anti-icing system is adequate under the conditions of freezing fog on the ground. anti-icing capability. Therefore, the applicant needs to conduct a test to verify that there is no icing on the leading edge of the engine inlet when the aircraft encounters freezing fog during route operation and needs to wait for takeoff. [0003] The icing meteorological conditions required in the airworthiness clauses are difficult to find in the natural environment. In order to break through the limitation of environmental conditions,...
