MGV-1SU8 Series 01

MGV-1SU8 Series 01 compact gyro vertical

MGV-1SU8 Series 01 is a compact aircraft gyro vertical used as a flight-navigation instrument for determining aircraft spatial position relative to the true horizon. The unit is built as a two-gyro force-stabilized platform and provides electrical signals proportional to roll and pitch angles. It is used as an onboard attitude reference source for flight-navigation equipment, indication systems, autopilot channels and related aircraft consumers.

Function of the MGV-1SU8 Series 01 gyro vertical

The main function of MGV-1SU8 Series 01 is continuous determination of aircraft roll and pitch. The unit measures the position of an aircraft or helicopter relative to the horizon plane and transmits this information as electrical output signals. These signals can be used by cockpit attitude indication, navigation systems, automatic flight control equipment and onboard stabilization circuits. The gyro vertical works as a remote avionics unit rather than as a standalone cockpit indicator.

Two-gyro force-stabilized platform

MGV-1SU8 Series 01 uses a two-gyro force-stabilized platform inside a compact housing. This construction combines gyroscopic sensing elements and stabilization mechanisms in one unit. The force-stabilized design helps the instrument maintain a stable vertical reference and reduce attitude errors during normal flight conditions. The unit includes caging / erection functions for bringing the platform to the vertical reference after power-up and during preparation for operation.

Application of MGV-1SU8 Series 01

MGV-1SU8 Series 01 and related MGV-1SK / MGV-1SU versions are used on Soviet and Russian civil, transport and special-purpose aircraft. The source context indicates application on Tu-154, Yak-42, An-72, An-74, Mi-26 and Ka-32 aircraft and helicopters, depending on the installed avionics configuration. Since exact use can vary by aircraft modification and system package, applicability should be confirmed by the aircraft equipment list and maintenance documentation.

Power supply and operating characteristics

The MGV-1SU8 Series 01 unit operates from both DC and AC aircraft power supplies. The source context indicates 27 V DC and 36 V AC at 400 Hz. After power-on, the gyro motors require a start-up and caging period before the instrument reaches operating readiness. The unit measures roll over a wide range and pitch within the specified aircraft attitude range. Static horizon-holding accuracy and recovery time after tilt are defined by the technical documentation.

Installation and ordering of MGV-1SU8 Series 01

MGV-1SU8 Series 01 is installed in an aircraft equipment compartment or avionics bay using a mounting flange and shock-mounted frame arrangement. The source context indicates a mounting zone of approximately 250 × 250 mm and possible use with an A-2V type shock-mounted frame. When ordering, the buyer should confirm the exact series, passport cipher, aircraft type, mounting frame requirement, condition, passport availability, repair certificate and test status.
