DRDO Transfers Stability Actuator Technology for AMCA to Godrej

The Defence Research and Development Organisation (DRDO) has transferred the technology (ToT) of Stability Actuators to Godrej Aerospace for India’s Advanced Medium Combat Aircraft (AMCA). This makes India one of the few countries capable of producing such flight-control systems domestically.

Stability actuators are electro-mechanical or hydraulic systems that control aircraft control surfaces such as elevators, ailerons, and rudders. They are part of the fly-by-wire (FBW) system, which uses electronic signals instead of mechanical linkages. For the AMCA, which is aerodynamically unstable for maneuverability, these actuators maintain balance, respond to pilot commands, and correct instability automatically during maneuvers. Without them, controlling the aircraft would be difficult.

The AMCA is India’s indigenous fighter program, and stability actuators help it perform maneuvers, reduce pilot workload, and ensure safety. Producing these actuators in India reduces dependence on foreign suppliers and improves integration with the aircraft’s control systems.

Godrej Aerospace, which has experience in defense and aerospace manufacturing, including engines and propulsion systems, will now handle production of these stability actuators, supporting India’s aerospace industry. With this transfer, India joins a small group of countries able to design and produce stability actuators for combat aircraft, supporting the AMCA program and reducing import dependency.

The AMCA project is expected to move into prototype development in the coming years, with DRDO and HAL working on design and production. The use of indigenous stability actuators will ensure proper integration and reliable performance.
