Mиг－23飞机尾旋试飞体会

Ｍиг－２３飞机是一种变后掠翼战斗机，它的尾旋动态及改出尾旋的方法很复杂。根据在该机上进行的四次尾旋飞行试验，叙述其尾旋进入的方法、尾旋中的动态和改出尾旋的方法。并举出三个典型的尾旋模态实例，详细记述整个尾旋过程和进行分析，说明Ｍиг－２３飞机尾旋动态的复杂性及其表现出的特点。最后，提出了几点在判断和改出Ｍиг－２３飞机的尾旋时应注意的事项。

FLIGHT EXPERIENCE ABOUT SPIN FLIGHT TEST FOR Mig-23 AIRCRAFT

Mig-23 aircraft is a kind of variable sweep wing fighter.Its spin dynamicand recovery method are extremely complex. Four times stall/spin flight test has ever beenoperated by myself in Mig-23 aircraft.This paper primarily discusses the entering methodof spin, the spin dynamic and recovery method for Mig-23 aircraft.As an example,threetypical spin modallty in which the entire spin process is detailed and analyzed are introducedborder to show the complex and characteristic of spin dynamic for Mig-23 aircraft.Finaily, some important suggestion is proposed for to judge and recover the spin of Mig-23 aircraft.
