Aerospace Instrument-Making Annotation << Back Disturbing moments of floating navigation instruments with the elastic casing Д.В. Кондратов, Л.И. Могилевич The article deals with the problem of defining vibrating errors of floating navigation instruments with elastic casing at the free butt ends leakage of liquid. The achieve the is goal the combined non-linear elastohydrodynamic problem is set up. As a result of solving this problem the constant component of hydrodynamic moment, defining the value of error was found. The calculations for floating gyroscope and floating pendulum accelerometer with cylindric floating suspension were given.
