飞行载荷分析计算研究

 介绍歼××飞机飞行载荷分析计算研究的一些内容,包括：飞行包线计算、机动过程计算、弹性修正、气动载荷和惯性载荷计算、全机平衡、控制面弯扭剪计算、载荷包线绘制和设计情况选取等十几个方面,井进行了分析。通过大量的计算结果和歼××飞机原设计载荷情况进行了比较,对今后如何贯彻和进一步研究《国军标》提出了一些看法。

ANALYTICAL INVESTIGATION OF THE AIRCRAFT FLIGHT LOADS

he main purpose of this paper is to introduce some efforts of the“Analvtical investi- gation of the aircraft flight loads”,which was one of the research tasks of the aircraft strength specification in the period of the seventh-five year program. Analytical results shown in this pa- per include:flight envelopes,manuvering histories,static elastic correction,aerodynamic loads and inertial loads,loading balance of the aircraft,bending moments,torsion moments and shear- ing loads at specified cross sections of the airframe. All these results were studied and compared with the original design loads conditions of the fighter aircraft. In addition,some points of view about further investigation and implementation of the“NATIONAL MILITARY SPECIFICA- TION OF TNE STRENGTH AND LOADS”are presented.
