This article analyses the possibility of employment of floated-type gyroscope suspension with nonzero total curvature. It is regarded as a method of passive reduction of measurement error influenced by the powerful shock wave. The surface of suspension is represented by catenoid. The radius of the shell part changes along the sinusoid δsin(πz) at zϵ[0,1], where is generatrix deflection in the middle bulkhead. The value of δ changes within the limits of 0,1•10-3-2,0•10-3 m. The quantative analysis gave an opportunity to choose the optimal value of generatrix deflection δ = 0.11•10-3 m, where the systematic error does not exceed (-0,1 g c-1). The estimated error confirms the reduction of error below bench test data. This means that the suspension with nonzero total curvature allows to reduce the influence of powerful shock waves on the sensitive elements of gyrostabilized platform. The data obtain may be used while designing the floated-type gyroscope for flying in hypersonic speed conditions.References
