隱身技術是指在一定範圍内降低所要隱身目標的信號特徵,使其難以被雷達和紅外等探測手段所發現的技術。其作用是縮短敵防禦系統的發現距離,使敵方來不及組織有效的攔截,以此來提高作戰飛機的生存力,增强突防能力,達到消滅敵人保存自己的目的。因此,隱身能力將是現代作戰飛機必須具備的重要性能之一。目前已受到各國的高度重視並列入國家的重點發展項目。隱身技術的發展簡况隱身技術起源於第二次世界大戰,經歷了探索時期、技術全面發展時期和應用時期三個階段。目前已進入深化研究和廣泛應用階段。五十年代的初步嘗試 Stealth technology is to reduce the signal characteristics of the target to be stealth within a certain range, making it difficult to be detected by radar and infrared detection techniques. Its role is to shorten the discovery distance of the enemy defensive system so that the enemy can not organize an effective interception in time to enhance the survivability of the combat aircraft and enhance the penetration capability so as to eliminate the purpose for the enemy to save himself. Therefore, stealth capabilities will be one of the most important features that modern combat aircraft must have. At present, it has been highly valued by all countries and has been included in the key development projects of the country. Stealth technology development Stealth technology originated in the Second World War, has gone through the exploration period, the full development of technology and application of the three stages. Has now entered the deepening research and extensive application stage. The first attempt of the fifties
