防喘装置是预防导弹发射造成发动机空中停车的一种安全措施。在现代战斗机上 ,有无高性能的防喘装置已成为评定飞机先进性的重要指标。对防喘装置的基本要求应是不失时机的有效防喘 (或退喘 ) ;对发动机和进气系统的动态扰动和性能损失要小 ,推力恢复要快 ;不因防喘装置工作而 Anti-asthma device is to prevent the launch of a missile engine parking in the air a safety measure. On modern fighter jets, whether or not high-performance anti-asthma devices have become an important indicator of the advanced nature of aircraft. The basic requirements of the anti-asthma device should be an effective anti-asthma (or retreat); the dynamic disturbance and loss of performance on the engine and intake system should be small, thrust recovery faster; not due to anti-asthma device work
