然而,由於供應鏈不穩定,特別是航太級原料短缺和專業鍛造能力有限,市場面臨許多重大障礙。這些營運中斷經常導致生產延誤和成本增加,使供應商難以按時交付。業界巨大的訂單積壓進一步加劇了這種壓力。根據國際航空運輸協會(IATA)統計,2024年累積未交付的新飛機訂單將達到創紀錄的17,000架。當前產能與持續需求之間的巨大差距,對市場的平穩發展構成了重大阻礙。
民航機機隊的擴張是全球飛機引擎軸市場的主要驅動力,對生產計畫產生了顯著影響。隨著航空公司積極更新機隊以滿足不斷成長的客運量並淘汰老舊低效的飛機,渦輪扇引擎的產量正達到歷史新高。這種擴張需要同時增加能夠承受複雜結構負荷和旋轉動態的關鍵低壓和高壓軸的產量。正如波音公司在2024年7月發布的《2024-2043年商用市場展望》中所述,未來20年,全球航空業預計將長期需要43,975架新的商用飛機,以擴大運力並取代老舊機隊。
同時,不斷成長的國防預算,尤其是用於加強空軍力量的預算,顯著增加了對高性能引擎部件的需求。各國政府優先採購下一代戰鬥機和軍用運輸機,這些飛機需要特殊設計的引擎軸,以承受比標準民航機軸更高的熱負荷和扭力。根據斯德哥爾摩國際和平研究所(SIPRI)於2024年4月發布的《2023年全球軍費開支趨勢》概況介紹,預計全球軍費開支將實際成長6.8%,達到2.443兆美元。這代表著對包括航空推進技術在內的國防技術的投資增加。採購量的激增支撐著整個推進系統供應鏈。例如,通用電氣航空航太公司報告稱,2023年全年訂單總額達792億美元,凸顯了引擎零件生產的強勁經濟勢頭。
供應鏈不穩定,尤其是專業鍛造能力和航太級原料的短缺,是限制全球飛機引擎軸市場擴張的一大障礙。這些軸需要高性能材料(例如鎳基高溫合金和鈦)以及精密鍛造技術的組合,才能承受極高的旋轉應力。目前這些特定資源的短缺導致生產嚴重受阻,因為製造商如果沒有這些關鍵零件就無法完成推進系統組裝。因此,鍛造框架和原料供應的短缺使得供應商無法將行業內大量的訂單轉化為實際收入,從而有效地限制了市場成長。
這些營運限制擾亂了整個航太價值鏈,導致儘管需求強勁,最終產品的交付卻出現嚴重延誤。近期生產數據表明,這些限制的嚴重性顯而易見。根據國際航空運輸協會(IATA)的數據,預計2024年全球飛機交付將降至1,254架,以金額為準,比疫情前的產量尖峰時段下降約30%。交付下降的主要原因是無法採購到關鍵的引擎零件,例如軸,而非訂單不足。這顯示供應鏈中斷正在實際抑制市場的成長潛力。
用於齒輪傳動渦輪扇 (GTF) 引擎的專用軸的進步正在顯著改變市場的技術格局。與傳統的直驅系統不同,齒輪傳動渦輪扇引擎將風扇與低壓渦輪和壓縮機分離,因此需要複雜的齒輪箱和高性能軸系來適應不同的轉速。這種設計顯著提高了推進效率並降低了噪音水平,從而推動了對現代推進系統所需的高扭矩、重型軸的需求不斷成長。這一趨勢的商業性成功顯而易見:根據 RTX 2024 年 7 月發布的新聞稿,普惠公司每年已獲得超過 950 台 GTF 引擎的訂單和契約,這表明市場對這些專用軸部件的需求持續旺盛。
同時,採用數位雙胞胎技術進行預測性維護正成為引擎營運商的關鍵附加價值服務。這項創新利用配備感測器的軸,將熱應力、振動和扭矩等即時資訊傳輸到虛擬模型,使營運商能夠從固定維護計劃轉向基於狀態的維護。透過在故障發生前預測零件疲勞,航空公司可以延長昂貴旋轉零件的使用壽命,並最大限度地減少非計劃性停機時間。蓬勃發展的售後市場凸顯了這些監測工具的經濟價值。 2025年1月,通用電氣航空航太公司報告稱,在龐大的裝機量基礎上,2024年全年商用引擎和服務訂單總量成長了38%。高效率的、數據主導的維護策略對於確保運作可靠性至關重要。
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.
