PG-1V-11

PG-1V-11 stabilized gyro platform for inertial systems

PG-1V-11 is an aircraft stabilized gyro platform used in navigation and flight systems of Il-76 family aircraft and related modifications, including Il-78 according to the source context. The platform is associated with inertial and damping-type navigation complexes, including systems of the I-11-76 type. It provides a stabilized base for inertial sensors and supports the generation of aircraft attitude and navigation data.

Function of the PG-1V-11 gyro platform

The main function of PG-1V-11 is physical stabilization of measuring elements relative to the true horizon. The platform keeps gyroscopes and linear accelerometers in a controlled spatial position while the aircraft maneuvers. This allows the system to determine aircraft orientation parameters, including roll, pitch and heading, and to support autonomous inertial navigation calculations. In the aircraft system, the platform works together with external electronic, control and signal-processing units.

PG-1V-11 in Il-76 navigation equipment

PG-1V-11 is used as part of onboard navigation and flight complexes installed on heavy military transport aircraft. The source context links the unit to Il-76 and Il-78 aircraft, where inertial equipment is used for flight parameter measurement, damping functions and autonomous navigation support. The platform may be connected with gyroscopes, accelerometers, frame drive circuits and control electronics that process signals for aircraft navigation and flight-control consumers.

Gimbal stabilization principle

The PG-1V-11 platform is based on a classical gimbal suspension arrangement. Signals from gyro angle sensors are transmitted to stabilization drive motors, which maintain the internal frame in a horizontal reference position. As the aircraft changes attitude, the platform control system compensates motion of the aircraft body and keeps the measuring frame aligned with the required reference. This principle allows inertial sensors to operate from a stabilized base instead of following every aircraft movement directly.

Sensor set and internal construction

According to the source context, a PG-1V-type platform may include three two-degree floated gyroscopes of the GPA-20 type or similar, and two DA-1 linear pendulum accelerometers. The platform is described as a sealed monoblock with a cylindrical-spherical housing and an internal multi-frame gimbal suspension. The internal volume may be filled with dried air or nitrogen to reduce moisture and condensation risk. Exact internal drawings and detailed parameters are normally defined in specialized manufacturer and aircraft maintenance documentation.

Ordering and maintenance of PG-1V-11

PG-1V-11 is a specialized aircraft inertial unit, so procurement should be based on the exact aircraft system configuration and documentation. The buyer should confirm whether the requirement is for the platform only, a platform with mounting frame, or a wider set with external electronic blocks and coordinate conversion equipment. Required condition, passport availability, storage records, repair certificate, test results and compatibility with the installed Il-76 / Il-78 navigation system should be checked before supply.
