本文从飞机方案设计的角度,并在同一设计要求的基础上,比较了无尾和有尾两种布局型式的优缺点。针对两种不同要求的歼击机,即超音速截击机和高机动性歼击机,作了无尾方案和有尾方案的比较。同时也研究了随控布局(放宽静安定度)对这两种方案的影响。 对于超音速截击机,无尾方案的主要飞行性能优于有尾方案。主要原因为阻力小和重量轻。对于高机动性歼击机,无尾方案仍然是一个具有竞争力的方案。随控布局(放宽静安定度)可以显著提高歼击机的机动性。应用随控布局,无尾方案比有尾方案可以得到更大的收益。
In this paper, the advantages and disadvantages of both tailless and tail-wise layout are compared based on the same design requirements from the perspective of aircraft design. For two different requirements of the fighter, namely the supersonic interceptor and high-mobility fighter, made a tailless program and a tail program comparison. At the same time, we also study the influence of the controllable layout (relaxation of static stability) on these two schemes. For supersonic aircraft, the main flight performance of the tailless scheme is superior to that of the tailless scheme. The main reason is resistance and light weight. For the high mobility fighter, the tailless program is still a competitive solution. With the control layout (to relax static stability) can significantly improve the fighter mobility. With a random layout, the tailless scheme can yield greater benefits than the tailed scheme.
