Study of Warm Influence on Stability of SINS Accelerometer Set Carier System Axes

Abstract

The authors propose a numerical approach to the study of thermal phenomena in the carrier system of the strapdown inertial navigation systems accelerometers set using the finite element method in three-dimensional formulation and an estimation of accelerometer's sensitivity axes deviation stability, which makes the most important contribution to the balance of errors of high-dynamic aircraft. The most promising series of structural solutions for carrier systems for various manifestations of thermal force displacements (deformations) in them is shown.
