在飞机方案设计阶段,仅仅是确定了飞机的翼面参数,机身的大致长度、直径、进气道的基本形式等,在此基础上还要进行一轮飞机总体布置协调。此时经常出现这种情况,即进行布置后发现,飞机的内部空间特别紧张或特别宽松。这时一般的作法是紧张的时候将机身加长加粗,宽松的时候将机身缩短或 In the design stage of the aircraft, only the airfoil parameters of the aircraft, the approximate length of the fuselage, the diameter, the basic form of the air intake, etc. are determined. On the basis of this, coordination of the overall layout of the aircraft is also to be carried out. This is often the case at this time, that is, after placement, it is found that the interior of the aircraft is particularly stressful or particularly loose. At this time, the general approach is tense when the body lengthened bold, loose body will be shortened or
