然而,由于供应链不稳定,特别是航太级原料短缺和专业锻造能力有限,市场面临许多重大障碍。这些营运中断经常导致生产延误和成本增加,使供应商难以按时交付。业界巨大的订单积压进一步加剧了这种压力。根据国际航空运输协会(IATA)统计,2024年累积未交付的新飞机订单将达到创纪录的17,000架。当前产能与持续需求之间的巨大差距,对市场的平稳发展构成了重大阻碍。
民航机机队的扩张是全球飞机引擎轴市场的主要驱动力,对生产计画产生了显着影响。随着航空公司积极更新机队以满足不断增长的客运量并淘汰老旧低效的飞机,涡轮扇发动机的产量正达到历史新高。这种扩张需要同时增加能够承受复杂结构负荷和旋转动态的关键低压和高压轴的产量。正如波音公司在2024年7月发布的《2024-2043年商用市场展望》中所述,未来20年,全球航空业预计将长期需要43,975架新的商用飞机,以扩大运力并取代老旧机队。
同时,不断增长的国防预算,尤其是用于加强空军力量的预算,显着增加了对高性能发动机部件的需求。各国政府优先采购下一代战斗机和军用运输机,这些飞机需要特殊设计的发动机轴,以承受比标准民航机轴更高的热负荷和扭力。根据斯德哥尔摩国际和平研究所(SIPRI)于2024年4月发布的《2023年全球军费开支趋势》概况介绍,预计全球军费开支将实际成长6.8%,达到2.443兆美元。这代表着对包括航空推进技术在内的国防技术的投资增加。采购量的激增支撑着整个推进系统供应链。例如,通用电气航空航太公司报告称,2023年全年订单总额达792亿美元,凸显了引擎零件生产的强劲经济势头。
供应链不稳定,尤其是专业锻造能力和航太级原料的短缺,是限制全球飞机引擎轴市场扩张的一大障碍。这些轴需要高性能材料(例如镍基高温合金和钛)以及精密锻造技术的组合,才能承受极高的旋转应力。目前这些特定资源的短缺导致生产严重受阻,因为製造商如果没有这些关键零件就无法完成推进系统组装。因此,锻造框架和原材料供应的短缺使得供应商无法将行业内大量的订单转化为实际收入,从而有效地限制了市场成长。
这些营运限制扰乱了整个航太价值链,导致儘管需求强劲,最终产品的交付却出现严重延误。近期生产数据表明,这些限制的严重性显而易见。根据国际航空运输协会(IATA)的数据,预计2024年全球飞机交付将降至1,254架,以金额为准,比疫情前的产量尖峰时段下降约30%。交付下降的主要原因是无法采购到关键的引擎零件,例如轴,而非订单不足。这显示供应链中断正在实际抑制市场的成长潜力。
用于齿轮传动涡轮扇 (GTF) 引擎的专用轴的进步正在显着改变市场的技术格局。与传统的直驱系统不同,齿轮传动涡轮扇发动机将风扇与低压涡轮和压缩机分离,因此需要复杂的齿轮箱和高性能轴系来适应不同的转速。这种设计显着提高了推进效率并降低了噪音水平,从而推动了对现代推进系统所需的高扭矩、重型轴的需求不断增长。这一趋势的商业性成功显而易见:根据 RTX 2024 年 7 月发布的新闻稿,普惠公司每年已获得超过 950 台 GTF 发动机的订单和合同,这表明市场对这些专用轴部件的需求持续旺盛。
同时,采用数位双胞胎技术进行预测性维护正成为引擎营运商的关键附加价值服务。这项创新利用配备感测器的轴,将热应力、振动和扭矩等即时资讯传输到虚拟模型,使营运商能够从固定维护计划转向基于状态的维护。透过在故障发生前预测零件疲劳,航空公司可以延长昂贵旋转零件的使用寿命,并最大限度地减少非计划性停机时间。蓬勃发展的售后市场凸显了这些监测工具的经济价值。 2025年1月,通用电气航空航太公司报告称,在庞大的装机量基础上,2024年全年商用发动机和服务订单总量增长了38%。高效率的、数据主导的维护策略对于确保运作可靠性至关重要。
The Global Aircraft Engine Shaft Market is projected to expand from USD 0.95 Billion in 2025 to USD 1.27 Billion by 2031, achieving a CAGR of 4.96%. This sector centers on the fabrication of high-strength rotating elements essential for transferring torque between the turbine and compressor sections of propulsion systems. Because these shafts are vital to engine operation, they must possess extraordinary durability to endure intense rotational velocities and thermal pressures. The market is principally propelled by the rising necessity for new military and commercial aircraft, a trend driven by the global increase in air passenger numbers and the extensive modernization of aging fleets. Furthermore, the industry's focus on enhanced fuel efficiency forces airlines to adopt next-generation engines, thereby directly intensifying the demand for these crucial components.

However, the market faces a substantial obstacle due to supply chain instability, specifically regarding the scarcity of aerospace-grade raw materials and limited specialized forging capabilities. These operational disruptions frequently lead to manufacturing delays and increased costs, complicating the ability of suppliers to adhere to delivery timelines. This pressure is exacerbated by the industry's immense backlog; according to the International Air Transport Association, the cumulative volume of unfulfilled new aircraft orders hit a record 17,000 units in 2024. This profound gap between current manufacturing capacities and sustained demand presents a formidable barrier to seamless market progression.
Market Driver
The growth of commercial aircraft fleets acts as a major driver for the Global Aircraft Engine Shaft Market, drastically influencing production schedules. As carriers aggressively update their operations to handle increasing passenger numbers and retire older, less efficient models, the manufacturing rates for turbofan engines have reached historic highs. This scale-up requires a concurrent boost in the production of essential low-pressure and high-pressure shafts capable of handling intricate structural loads and rotational dynamics. As noted by Boeing in their 'Commercial Market Outlook 2024-2043' released in July 2024, the aviation industry anticipates a long-term global requirement for 43,975 new commercial airplanes over the coming two decades to manage capacity growth and replace aging stock.
Simultaneously, rising defense budgets focused on aerial warfare capabilities are significantly increasing the need for high-performance engine parts. Governments are prioritizing the procurement of next-generation fighter jets and military transport aircraft, which demand specialized engine shafts built to endure greater thermal loads and torque compared to standard civilian versions. According to the Stockholm International Peace Research Institute's April 2024 'Trends in World Military Expenditure, 2023' Fact Sheet, global military spending rose by 6.8 percent in real terms to 2,443 billion USD, indicating increased investment in defense technologies like aerial propulsion. This purchasing surge supports the entire propulsion supply chain; for instance, GE Aerospace reported total full-year orders of 79.2 billion USD for 2023, highlighting the strong financial momentum underpinning engine component production.
Market Challenge
Supply chain instability, particularly the shortage of specialized forging capacity and aerospace-grade raw materials, represents a critical hurdle that directly impedes the Global Aircraft Engine Shaft Market's expansion. These shafts necessitate high-performance inputs, such as nickel-based superalloys and titanium, combined with precision forging to survive extreme rotational stresses. Existing deficits in these specific resources result in severe production bottlenecks, as manufacturers are unable to finalize propulsion system assemblies without these vital parts. Consequently, the failure to secure forging slots and raw materials stops suppliers from transforming the industry's massive order backlog into actual revenue, effectively limiting market growth.
This operational strain disrupts the entire aerospace value chain, resulting in substantial delays in end-product delivery despite strong demand. The severity of this limitation is highlighted by recent output data. According to the International Air Transport Association, global aircraft deliveries in 2024 dropped to 1,254 units, a figure roughly 30% lower than pre-pandemic production highs. This decline in deliveries, caused primarily by the inability to source critical engine components like shafts rather than a scarcity of orders, illustrates how supply chain fractures are actively restraining the market's growth potential.
Market Trends
The advancement of specialized shafts for Geared Turbofan (GTF) engine configurations is significantly reshaping the technological dynamics of the market. In contrast to traditional direct-drive systems, geared turbofan engines separate the fan from the low-pressure turbine and compressor, requiring an intricate arrangement of gearboxes and high-performance shafts to handle differing rotational speeds. This design greatly improves propulsive efficiency and lowers noise levels, fueling a rise in demand for the robust, high-torque shafts needed for these modern propulsion systems. The commercial success of this trend is clear; according to an RTX press release in July 2024, Pratt & Whitney accumulated over 950 orders and commitments for their GTF engines within the year, indicating a lasting production need for these unique shaft components.
At the same time, the adoption of Digital Twin technology for predictive shaft maintenance is becoming a vital value-added service for engine operators. This innovation involves using sensor-equipped shafts that relay real-time information regarding thermal stress, vibration, and torque to a virtual replica, allowing operators to shift from fixed schedules to condition-based maintenance. By anticipating component fatigue before failure, airlines can extend the lifespan of these costly rotating parts and minimize unplanned downtime. The financial drive for such monitoring tools is highlighted by the thriving aftermarket; GE Aerospace reported in January 2025 that total orders for commercial engines and services increased by 38 percent for the full year 2024, creating a vast installed base that requires efficient, data-led maintenance strategies to ensure operational reliability.
