飞机重心位置的计算分析方法

飞机重心位置对飞机的安定性和操纵性影响很大.不在飞机重心允许范围内装货或载客时,会使飞机操纵性和安定性变差,影响飞行安全.飞机重心位置计算分析是新型飞机研制、现役飞机加改(换)装设计等工程中必不可少的一个重要环节.以某型现役飞机进口短波单边带电台换装国产短波自适应/跳频电台工程作为研究对象,研究了基于力矩平衡法的飞机重心位置计算方法,计算了该型飞机换装短波电台后空机重心位置.计算结果表明,该型飞机进口短波电台换装国产短波电台后,空机状态下的重心位置满足重心允许范围要求.

Methods of Calculating and Analysis of Aircraft's Gravity Position

Aircraft's gravity position had a great influence on the stability and maneuverability of aircraft. Beyond the scope of allowed variations when loading or passengers,the aircraft's maneuverability and sta-bility became worse,and it's flight safety was affected. Calculating and analyzing of aircraft's gravity posi-tion was an important part in engineering design,such as new aircraft's development and existing aircraft's modification. In this paper,methods of calculating and analyzing of aircraft's gravity position was studied . The results of calculating and analyzing showed that after import shortwave SSB radio equipments changed by domestic shortwave SSB radio equipments,aircraft's gravity position in empty station met the requirements of this type aircraft's allows range.
