In a nutshell, landing gear in an aircraft provides suspension and movement during take-off, landing, and taxi. The sudden shock of landing impact is absorbed by the landing gear as it is designed for that purpose. It is considered one of the crucial components of an aircraft, they are controlled by pneumatic and hydraulic systems and they have a specified service life. For Example, the average life of a landing gear is 5 years and they will go for replacement after the same time period. The key market players benefit from these replacements and overhauls. The market will witness a high growth rate in the future period. In terms of geography, the most significant provider of helicopter landing gear is North America. To strengthen their defense capabilities many countries are increasing their investment in military aircraft, which in turn fuels the growth of the market. There is an increase in the adoption of UAVs in military operations, which is anticipated to increase the growth of the market. Landing gear components such as wheels, actuation systems, and brakes will undergo wear and tear and it need maintenance operations a prescribed intervals. The MRO receives more revenue from these replacements. In addition, to modernize aircraft fleets the national defense budget is increased, and the replacement of conventional landing gear with an advanced gear system is expected to increase the market growth further. In an aircraft, the aircraft landing gear is a heavily loaded structure. Out of the total weight of the aircraft, 3% to 6 % weighs the aircraft’s landing gear. The companies are ready to manufacture lighter and more robust landing gear without removing its functions, performance, maintenance, operations, and safety requirements. By using materials of fracture toughness, fatigue properties, and higher strength, this is made possible. These materials include corrosion-resistant steel, high- strength aluminum alloys, ultra-high-strength alloy steels, titanium alloys, and composites. The reason behind the use of composite materials in aircraft and landing gear is that it provide stiffness properties and super-specific strength. For example, carbon composite disc brakes provide longer life, lower maintenance, and reduced weight. The cost of manufacturing composite is very high but presently it has been overcome using different production techniques. These factors fuel the Landing Gear Market growth in the forthcoming years. Focusing on intelligent fleet building that provide future network flexibility, improving efficiency and sustainability, and maximizing capability while minimizing risk. In aircraft today, the landing gear is retracted and extended using power drawn from complex, centralized and heavy hydraulic systems that also power aircraft flight control services. Efficiency is increased using new technologies and materials. Lighter composites and titanium materials developments are made to reduce the weight of the landing structures.
