FIELD: measurement technology; instrument making industry. ^ SUBSTANCE: proposed device that may be found useful for inertial systems of mobile objects such as small-size airplanes, space vehicles, and other vehicles has case and moving base made in the form of hollow rotor accommodating even number of sensing elements of pendulous accelerometers incorporating signal conversion unit. Sensing elements of pendulous accelerometers are mounted for vibrating in plane chosen as a minimum from two relatively perpendicular planes of which one is equatorial for rotor and remaining planes are meridian ones. Pendulous-accelerometer sensing-element arms are disposed in pairs in rotor motion (rotation) plane symmetrically to rotor axis of revolution; they are secured on rotor hollow periphery and radially directed to axis of revolution. Inertial masses of pendulous-accelerometer sensing elements are flat in shape and function as movable electrode of capacitor, fixed electrode in the form of plate being attached to case. In the process sensing element generates signal transferred to signal conversion unit. In addition sensing elements of pendulous accelerometers can be made in the form of two monolithic assemblies of which one incorporates sensing elements designed for vibrating in equatorial plane of rotor and those of other assembly, for vibrating in meridian plane. ^ EFFECT: enlarged functional capabilities and reduced size of device. ^ 2 cl, 7 dwg |
