一般认为,第四代战斗机应该具备隐身、超声速巡航、超机动和网络战等能力。其中,隐身能力是最引人注目的。F-22是第一架集上述能力于一身的战斗机,代表了目前世界战斗机技术发展的顶峰。本文将以 F-22战斗机作为案例,分析第四代战斗机隐身性能的相关问题。隐身性能与飞行性能空战的理想境界是把空中战场推到敌方的天空去。只有征服了敌人头顶的天空,才能打击敌人脚下的大地,并保护己方的陆海军不受敌人的空中打击。F-22所代表的“空中主宰”(airdominance)作战思想,不再满足于在 Generally believed that the fourth generation fighter should have stealth, supersonic cruise, super maneuver and network warfare capabilities. Among them, stealth ability is the most striking. The F-22 is the first fighter to combine these capabilities and represents the pinnacle of technology development for the current world fighter. This article will be F-22 fighter as a case to analyze the fourth-generation fighter stealth performance related issues. Stealth performance and flight performance The ideal state of air combat is to push the air battlefield to the enemy’s sky. Only by conquering the sky above the enemy’s head will it be possible to strike the ground under the enemy’s foot and protect our own land and navy from the enemy’s air strikes. The “airdominance” operational thinking represented by F-22 is no longer content with
