CGV-10P Series 04

CGV-10P Series 04 central gyroscopic vertical

CGV-10P Series 04 is an aircraft central gyroscopic vertical used as a two-gyro force-stabilized attitude reference unit. The instrument determines the spatial position of an aircraft relative to the local true vertical and measures roll and pitch angles for onboard systems. It is used in flight-navigation complexes of heavy transport and civil aircraft, including Il-76TD / Il-76MD and Tu-154 aircraft, depending on system configuration and documentation.

Function of the CGV-10P attitude reference unit

The main function of CGV-10P Series 04 is continuous measurement and output of aircraft roll and pitch data. The unit provides electrical signals proportional to aircraft attitude angles and distributes them to flight control, navigation, indication and stabilization systems. These signals are used by automatic flight control systems, command flight director indicators, attitude indicators, navigator displays, heading systems and radar stabilization circuits.

CGV-10P Series 04 in aircraft systems

In an aircraft installation, CGV-10P normally works as part of a redundant attitude reference set. The source context describes a system with three CGV-10P units: left, right and control gyroscopic verticals, operating together with a comparison unit. This architecture increases fault tolerance and allows aircraft systems to compare attitude data from several independent vertical references. Such redundancy is important on heavy transport aircraft where attitude information is used by multiple critical consumers.

Force stabilization principle of CGV-10P

CGV-10P uses a two-gyro force-stabilized scheme. The two gyroscopes and force unloading / stabilization circuits reduce dynamic errors during turns, maneuvers and aircraft evolutions. Compared with simpler free gyroscopic systems, force stabilization improves vertical holding accuracy and reduces the effect of external disturbing moments. This allows the unit to maintain reliable roll and pitch reference data during normal flight, maneuvering and moderate turbulence.

Series 04 design and integration features

The Series 04 version refers to a specific constructive and electrical execution of the CGV-10P unit. The source context links the series with internal potentiometric or selsyn sensors, connector configuration and integration requirements for particular aircraft types. The unit is housed in a cast aluminum cylindrical container with a mounting flange and shock-mounted frame. Exact installation dimensions and connector configuration should be checked by the product passport and aircraft system documentation.

Application and ordering of CGV-10P Series 04

CGV-10P Series 04 is used on aircraft requiring a central attitude reference for multiple onboard consumers. Typical consumers include SAU / autopilot, KPP command flight director indicators, cockpit attitude indication, TKS-P heading systems for GA-3 gyro stabilization, and radar antenna stabilization circuits. When ordering, the buyer should confirm the exact series, aircraft type, system configuration, condition, passport availability, repair documentation, test results and whether the unit must be supplied with its mounting frame.
