The invention is suitable for the technical field of wind tunnel tests, and provides an icing wind tunnel anti-icing and deicing test method and system. The method comprises the following steps of: setting a periodic control law grid; carrying out a primary periodic electric heating anti-icing and deicing test; updating the periodic control law grid according to the following conditions to obtainan updated periodic control law grid: after the primary periodic electric heating anti-icing and deicing test is completed, if the surface of a to-be-tested part is still iced, increasing the on-statetime in the periodic control law grid; after the primary periodic electric heating anti-icing and deicing test is completed, if overflow ice appears on the surface of the to-be-tested part, increasing the off-state time in the periodic control law grid; and performing the periodic electric heating anti-icing and deicing test again by using the updated periodic control law grid. According to the icing wind tunnel anti-icing and deicing test method and system, the periodic control law is simple to set, and icing and ice overflowing are not prone to occurring after the test.
本发明适用于风洞试验技术领域,提供了一种结冰风洞防除冰试验方法及系统,其包括如下步骤:设置周期性控制律网格;进行初次周期性电热防除冰试验;按照以下条件更新周期性控制律网格,得到更新后的周期性控制律网格:完成初次周期性电热防除冰试验后,如果待测试部件的表面仍发生结冰,则增加周期性控制律网格中的通状态的时间;完成初次周期性电热防除冰试验后,如果待测试部件的表面出现溢流冰,则增加周期性控制律网格中的断状态的时间;以更新后的周期性控制律网格再次进行周期性电热防除冰试验。本发明的结冰风洞防除冰试验方法及系统,周期性控制律设置简单、试验后不容易出现结冰、溢流冰。
