| 摘 要： | 用有限基本解方法研制成翼身组合体升力和力矩的计算程序。以当量回转体代替机身,机翼可以有后掠、厚度及弯度。厚度问题用线源模拟,先予解决。然后求解升力问题,这时考虑了厚度的影响。此法简单且有一定的精度。本文还计算了一些实例,并与实验作了比较。对机身影响、机翼的后掠和根梢比等作了简要的讨论。

| Abstract: | With the finiteelementary solution method,a computer program has been developed for the calculation of the lift and moment of the wing-body combination.An equivalent revolution is employed as a substitution for the body.The wing may be a sweptback cambered wing having a thickened root.First,with the simulation of line source,the thickness problem is solved.Then the lift problem is solved with the effect of thickness considered.This method is simple and fairly accurate.Some available configurations are calculated and the results are compared with test data. Some problems are also discussed briefly.They are the effect of body,the sweepback and the root-to-tip ratio of wing. |
