An aircraft gearbox is a mechanical device used in aircraft propulsion systems to control and transfer the power generated by the engines. It is a type of transmission that connects the engine to the aircraft's propellers and allows for the adjustment of rotational speed and torque, contributing to the safe and efficient operation of the aircraft. The output torque and speed of a gearbox are determined by the shafts attached to it and by the internal configuration of the gearbox. An aircraft gearbox is used to adjust a motor's speed (RPM) or increase its output torque.
The aircraft gearbox market consists of sales, by entities (organizations, sole traders and partnerships), of aircraft gearboxes that are used in aircraft propulsion systems. An aviation gearbox's main function is to change the engine's high-speed, low-torque output into a lower-speed, higher-torque output that can drive the propeller or rotor. The gearbox allows the propeller or rotor to revolve at the proper speed for the best aircraft performance while allowing the engine to run efficiently at its best speed.
The global aircraft gearbox market was valued at $3,259.73 million in 2019 which grew till 2024 at a compound annual growth rate (CAGR) of more than 2.00%.
Rise In Demand For Hybrid-Electric Aircraft
The rise in demand for hybrid-electric aircraft propelled the growth of the aircraft gearbox market in the historic period. Hybrid-electric aircraft combine conventional engines with electric motors, requiring specialized gearboxes to efficiently manage power distribution between the two sources. These gearboxes are essential for optimizing engine performance, ensuring smooth power transfer and enhancing overall efficiency. For instance, in January 2025, according to an article published by Airbus SE, a European aerospace corporation, the EcoPulse project, a collaborative effort between Airbus, Daher, and Safran, has concluded its flight test campaign, yielding promising results for the future of hybrid-electric aviation. The demonstrator, based on a modified Daher TBM 900 turboprop aircraft, conducted its first flight on November 29, 2023, and completed approximately 100 flight hours over 50 test flights by July 2024. Therefore, the rise in demand for hybrid-electric aircraft supported the growth of the aircraft gearbox market.
Advanced Gearbox Design Doubles Time Before Overhaul For Heavy Twin Helicopter
Major companies operating in the aircraft gearbox market are focused on developing advanced gearbox design doubles time before overhaul for heavy twin helicopters. Heavy twin helicopters are widely used in critical sectors such as offshore oil and gas operations, search and rescue missions and military applications, where minimizing downtime is crucial. By extending the TBO, these advanced gearboxes improve the helicopter's availability, allowing operators to complete more missions without frequent maintenance interruptions. This not only reduces maintenance costs but also enhances fleet utilization, improving overall profitability for operators. For instance, in February 2023, Airbus Helicopters, a France-based company that provides the most efficient helicopter solutions, launched an upgraded main gearbox for the H225 as the airframer continues to invest in the heavy twin to raise safety standards and reduce the maintenance workload for customers. The new gearbox, known as the e-MGB, will increase the component's time before overhaul (TBO) from 1,000 hours to 2,000 hours. This enhanced MGB will provide increased robustness and alleviate the maintenance plan of the H225. H225, are the engines composed of modules that can be replaced independently for ease of maintenance.
