China's General Aviation Engine Market Enters Order Fulfillment Phase: Over 42,000 Units Demand Expected in 20 Years
Policy–Industry–Capital Triple Resonance: China’s Commercial Spaceflight and General Aviation Propulsion Industries Enter the “Order Fulfillment Phase”
By the end of Q1 2025, China’s capital markets had quietly completed a structural leap forward: In the final week of March, Shenjian Co., Ltd. surged—recording three consecutive trading-day limit-ups—propelling the entire commercial spaceflight sector upward. Almost simultaneously, the innovative pharmaceuticals index posted five consecutive limit-ups, with heavyweight constituents such as Hengrui Medicine and BeiGene breaking above their annual moving averages on significantly increased trading volume. A deeper signal emerged from the policy front: The Ministry of Industry and Information Technology (MIIT) and the Civil Aviation Administration of China (CAAC) jointly released the Development Roadmap for General Aviation Propulsion Equipment (2025–2045)—for the first time explicitly forecasting that China’s incremental demand for general aviation engines over the next two decades will exceed 42,000 units, with turboshaft, turboprop, and novel electric propulsion systems collectively accounting for 78% of that total. This figure is not a speculative long-term vision—it is a conservative projection grounded in verifiable, near-term order milestones: the expansion of low-altitude airspace reform pilots; accelerated airworthiness certification for electric vertical takeoff and landing (eVTOL) aircraft; and the official rollout of procurement lists for emergency rescue and urban air mobility (UAM) applications. The convergence of these three forces signals a historic transition for China’s high-end manufacturing sector—from an era dominated by technological breakthroughs and policy expectations—to one defined by large-scale mass production and commercially viable, closed-loop realization.
General Aviation Propulsion: A Paradigm Shift—from “List of Critical Import Dependencies” to “Trillion-Yuan Order Pool”
For decades, aero-engines have been regarded as the “crown jewel” of high-end manufacturing. Within this domain, general aviation propulsion—characterized by low-volume, high-variety production and stringent reliability requirements—has ranked among the most import-dependent subsectors in China. Prior to 2023, domestic turboshaft engine localization stood below 15%, with critical components—including single-crystal superalloy turbine blades and Full-Authority Digital Engine Control (FADEC) systems—relying heavily on foreign suppliers. Yet a turning point emerged in 2024: AVIC Hunan Power successfully delivered its first batch of AEF125 turboshaft engines for installation on the AC313A helicopter. With hot-section component life reaching 3,000 hours, the engine achieved full domestic supply-chain integration for the first time. More critically, in February 2025, EHang Intelligent’s EH216-S became the world’s first manned eVTOL aircraft to receive a Type Certificate—its dual-redundant electric propulsion system sourced entirely from domestic suppliers: Jinjin Electric supplied permanent-magnet synchronous motors; CATL developed custom high-energy-density solid-state battery modules; and AVIC Opto-Electronics provided high-voltage cabling and thermal management systems. This milestone marks a fundamental divergence in technical pathways: while traditional gas turbines continue playing catch-up, electric propulsion has seized a new lane—achieving “leapfrog advancement” through strategic repositioning.
According to projections by the China Aviation Industry Development Research Center, the electric propulsion systems market will reach RMB 200 billion (≈USD 27.8 billion) between 2025 and 2035, growing at a compound annual growth rate (CAGR) exceeding 45%. Growth drivers extend well beyond eVTOL airframe volume (domestic operational fleets are projected to surpass 50,000 units by 2030)—they also stem from technology spillover effects: unmanned aerial vehicle (UAV) logistics (SF Express’s Fengyi and JD Logistics have launched procurement plans targeting tens of thousands of units); high-altitude, long-endurance solar-powered UAVs (e.g., AVIC UAV’s “Jiutian” platform); and even military unmanned loyal wingman propulsion systems—all demanding lightweight, high-power-density, intelligently managed electric propulsion solutions. This trend—“deep penetration of new-energy technologies into aviation”—is fundamentally reshaping industry valuation logic. Investors no longer focus solely on traditional metrics like thrust-to-weight ratio or specific fuel consumption; instead, they prioritize motor control algorithm iteration speed, battery thermal runaway protection ratings, and AI-driven predictive maintenance capabilities.
Commercial Spaceflight: An Ecological Restructuring—from “State-Led Dominance” to “Private Sector Leadership”
Shenjian’s triple limit-up was no isolated event. Its core driver lies in securing large-volume orders for rocket airframe structural components and solid-propellant engine casings—directly supplying next-generation reusable launch vehicles including LandSpace’s Zhuque-3 and CASIC’s Li Jian-2. Data shows that in Q1 2025, China conducted 17 commercial space launches, representing 63% of all national launch activity—with private enterprises responsible for 81% of those missions. Even more telling is the transformation in delivery models: the traditional “one rocket, one contract” custom-production paradigm is giving way to the emerging “Power-by-the-Hour” (PBH) service model. Companies such as iSpace and Galactic Energy have already signed low-earth-orbit (LEO) remote-sensing constellation operations and maintenance agreements with local governments—shifting their revenue model from hardware sales to data services plus on-orbit support. This evolution, in turn, compels upstream propulsion suppliers to develop robust full-lifecycle cost management capabilities.
This shift profoundly influences capital market valuation frameworks. When investors read Shenjian’s announcement of a RMB 970 million (≈USD 135 million) order for a solid rocket booster casing—with delivery cycle compressed to just eight months—they interpret far more than top-line revenue growth. They see clear evidence that China’s commercial spaceflight industry has definitively crossed the technological validation threshold and entered a new phase characterized by standardization, batch production, and service-oriented business models. Against this backdrop, synergy between general aviation propulsion and commercial spaceflight becomes strategically vital: the former provides “capillary-level” transport capacity for the low-altitude economy; the latter constructs an “information nervous system” for orbital infrastructure. Together, they form the three-dimensional foundational layer of China’s national aerospace infrastructure.
A New Global Landscape of Competition & Cooperation: The Low-Altitude Economy Emerges as a New Frontier in Great-Power Technological Rivalry
International developments provide vivid context. The deployment of U.S. Air Force F-35A fighters at Misawa Air Base in Japan appears merely as routine equipment modernization—but in reality underscores the U.S.–Japan strategic push to reinforce air dominance across the Western Pacific. Meanwhile, China’s low-altitude airspace management reforms have rolled out nationwide across 12 provinces, including Anhui, Hunan, and Hainan; and cities such as Shenzhen and Hefei have launched the nation’s first commercial eVTOL test flight routes. Technical standardization contests are intensifying: the U.S. Federal Aviation Administration (FAA) champions ASTM F3493-23, emphasizing fail-safe design against single-point failures; whereas CAAC’s Safety Requirements for Civil Unmanned Aircraft Systems places greater emphasis on multi-source redundancy and AI-enabled autonomous decision-making. This divergence reflects contrasting technological philosophies: the former pursues absolute physical reliability under extreme conditions; the latter embraces dynamic fault tolerance within complex adaptive systems.
Meanwhile, Moonshot AI’s Kimi K2.5 large language model recently surpassed USD 100 million in Annual Recurring Revenue (ARR)—with approximately 37% of its API call volume directed toward aerospace clients, supporting applications such as flight trajectory optimization, material defect identification, and engine health diagnostics. This reveals a deeper truth: large language models (LLMs) are rapidly evolving into the “digital twin central nervous system” for advanced equipment. China’s unique advantages across three dimensions—computing infrastructure (e.g., the East–West Data Transfer Project), industry-specific data accumulation (CAAC’s operational database openness rate stands at 82%), and closed-loop application scenarios (the Zhuhai Airshow now features a dedicated Low-Altitude Economy Exhibition Zone)—may well reshape the global competitive landscape for the low-altitude economy—not as fragmented product exports, but as integrated, systemic exports of hardware + software + services + standards.
Conclusion: A Historic Inflection Point—from “Catching Up Along the Curve” to “Defining the Curve”
The projected demand for 42,000 general aviation engines, the RMB 200 billion (≈USD 27.8 billion) electric propulsion market, and private enterprises conducting over 80% of commercial space launches—these figures, taken together, trace a clear evolutionary arc: China’s high-end manufacturing sector is decisively moving beyond the old narrative of “benchmarking and catching up,” entering a new epoch defined by standard-setting, ecosystem leadership, and paradigm exportation. When policy authorities issue explicit timetables, industrial players deliver bulk orders, and capital markets assign sustained premium valuations, the signal emanating from this triple resonance could not be clearer: “self-reliance and controllability” is no longer just a slogan—it is an unfolding industrial reality. This quiet yet profound transformation will ultimately elevate China—from a mid-tier participant in the global high-end equipment value chain—to the apex position of rule-maker and value allocator.
