Aerospace manufacturers are catering to these increasing demands and, therefore, offer sophisticated, advanced and reliable gearbox systems. Therefore, the expanding aviation industry will drive the growth of the global aircraft gearbox market.

  • Triumph Group Inc., a top manufacturer for aerospace and defence, announced that General Electric had awarded its Geared Solutions unit a new, long-term contract to supply "thousands" of inlet gearboxes (IGB) yearly for all three LEAP commercial aviation engine types. The two narrowbody jets with the greatest current sales figures, the Boeing 737 MAX and the Airbus A320neo, both have LEAP engines installed. Combined, Airbus and Boeing have order backlogs of about 10,000 twin-engine aircraft, which are scheduled for delivery over the course of the next ten years.

The high manufacturing, acquisition and maintenance costs The design and development of aircraft gearboxes involves a significant amount of engineering and certification processes that are time-consuming and capital-intensive. Aircraft gearboxes use sophisticated materials, which further adds to the costs. More costs are added when aircraft systems are modified to integrate modern gearboxes. Regular inspections, wear and tear, and component replacements increase maintenance costs. Therefore, the high acquisition and maintenance costs will hamper the market's growth.


There is a growing need to improve fuel economy and ensure sustainability advanced and sophisticated aircraft gearbox technologies drive sustainability and enable the aviation industry to contribute to a greener economy. They optimize engine performance and thereby enhance overall fuel efficiency. The incorporation of advanced propulsion systems helps reduce emissions and improve efficiency. Noise reduction and vibration damping achieved through gearbox technologies contribute to a quieter and more environmentally friendly aircraft operation. Furthermore, gearboxes facilitate the integration of hybrid and electric propulsion systems, aligning with the industry's exploration of greener technologies. These advancements will offer lucrative market growth opportunities during the forecast period.

  • Rolls-Royce's UltraFan power gearbox broke a world aeronautical record at its German factory. The gearbox tested at Dahlewitz, close to Berlin, reached 87,000 horsepower, or 64 megawatts. The power milestone was reached as work progressed on the power gearbox that will be supplied for the real UltraFan demonstrator engine, UF001. Scalable for both narrowbody and widebody aircraft, UltraFan is a vital component of Rolls-Royce's mission to improve the sustainability of travel. According to Rolls-Royce, gas turbines will remain the mainstay of long-haul aviation for many years. The company anticipates that UltraFan's efficiency will help make the transition to more sustainable fuels—which will probably cost more in the short run than traditional jet fuel—more financially feasible.
