Reducing the aerodynamic drag of bodies of revolution at supersonic speeds due to the creation of a bottom thrust is an important subject of aeromechanics. In the framework of this problem, it is proposed to perform numerical experiments on a model with a detachable bottom. It is assumed that the detachable bottom is affected by the main air flow jets separating from the surface of the body of revolution. The gas is reflected from the bottom and acts on the body of revolution, creating a bottom thrust and accelerating it.

旋转物体加速情况下的数值实验

减小由于产生底部推力而导致的超音速旋转体的空气动力学阻力是空气力学的重要课题。在此问题的框架内，建议对底部可拆卸的模型进行数值实验。假定可分离的底部受到与旋转体表面分开的主要气流的影响。气体从底部反射并作用于旋转体，产生底部推力并使其加速。
