机载外挂物地面间隙指标及确定方法

机载外挂物地面间隙作为机载外挂物地面相容性设计中的一项重要指标，是决定飞机外挂方案配置的重要因素之一，也是保障飞机及其外挂物使用安全的重要指标。而军标所给出的地面间隙指标没有按飞机在地面的动态使用过程考虑，难以保证飞机及其外挂物的使用安全，文中则根据飞机的实际使用，并充分考虑飞机在地面的动态使用过程，提出了一个科学合理的地面间隙指标的确定方法。

The Index of the Ground Clearances of the Airborne External Stores and How to Determine the Minimum Ground Clearances

The ground clearances of airborne stores is a very important index in the ground compatibility design of airborne stores. It''s also one of major factors in determining the scheme of aircraft external carriage. It'' s concerned with the aircraft and aircraft external carriage'' s safety.But in the military standard of both American and Chinese , the measure of determining the ground clearances is not concerned with the aircrafe''s taking - off and landing process on the ground , so it cannot ensure the aircraft and aircraft external carriage'' s safety. This article is written for putting forward a scientific measure in determining the ground clearance , according to the'' practical use of aircraft , especially through fully considering the aircraft'' s taking- off and landing process.
