FIELD: weapons and ammunition.
SUBSTANCE: aerodynamical stabiliser consists of fairing with fixing slots and blades that fold on axes. Fairing shell in zone of fixing slots location is arranged with local bulges equal to 0.8-1.2 of blade thickness in root section. Bulges make it possible to provide for contact of blade eyes with fairing along surface equal to 0.25-0.35 of blade root section area. Thickness of end part of blade in millimetres makes millimetres, where Mmax is maximum flight Mach number;
is frequency of own bending vibration of blade at maximum aerodynamical heating, Hz.
EFFECT: increased distance and accuracy of shooting due to elimination of blades and fixing slots shape variations in fairing as a result of temperature deformations and absence of vibrations and provision of low amplitude of blade bending vibration.
