FIELD: aeronautical and space engineering. SUBSTANCE: polyspherical fairing is made in form of cone with grooves on its lateral surface. Each groove is formed by surfaces of engageable spheres with centers in cone axis. Conjugating circumferences are located on surface of inscribed cone whose vertex and axis coincide with those of fairing cone at apex angle of 0.399 to 0.999 of apex angle of fairing cone. EFFECT: enhanced stability of flight and reduced drag. 2 cl, 2 dwg
