China’s AES100 Helicopter Engine Advances Aviation Self-Sufficiency
China certifies first domestic 1,100kW turboshaft helicopter engine, reducing reliance on Western tech and boosting Made in China 2025 aerospace goals.
China’s aviation sector has taken a decisive step forward with the approval of the AES100, the country’s first domestically developed 1,100-kilowatt turboshaft helicopter engine. This development marks a critical milestone in Beijing’s broader effort to achieve technological self-sufficiency in aerospace, particularly amid escalating export restrictions from the United States. The AES100, developed by the state-owned Aero Engine Corporation of China (AECC), has now received a type certificate from the Civil Aviation Administration of China (CAAC), signaling readiness for mass manufacturing and integration into operational platforms.
For decades, China has relied heavily on foreign suppliers for high-performance aircraft engines, particularly from Western countries. However, ongoing geopolitical tensions have intensified the urgency of establishing an independent aerospace supply chain. The AES100 is not just a technical achievement; it is a strategic move aligning with national priorities like the “Made in China 2025” initiative, which emphasizes domestic innovation in high-tech industries, including aerospace propulsion systems.
While the AES100 is primarily intended for helicopter applications, its successful development sends a broader message: China is narrowing the gap with global aerospace leaders and asserting its ambition to become a dominant player in both military and civilian aviation markets. The implications of this development extend beyond engineering into areas of national security, economic competitiveness, and global market dynamics.
The AES100 represents a new generation of turboshaft engines designed to power medium-lift helicopters used in both civilian and military contexts. According to AECC, the engine meets or exceeds performance standards required for advanced rotorcraft, including efficiency, reliability, and operational flexibility. The 1,100-kilowatt output positions it competitively against international counterparts, enabling China to reduce dependency on imported engines from manufacturers such as Safran Helicopter Engines (France) or General Electric (US).
One of the key breakthroughs in the AES100’s development was the integration of advanced materials and digital control systems. These technologies improve thermal efficiency and reduce maintenance cycles, making the engine suitable for varied mission profiles, including search and rescue, transport, and reconnaissance. The engine’s modular design also facilitates easier upgrades and maintenance, aligning with global trends toward flexible, scalable propulsion systems.
Li Gaiqi, chief designer of the AES100, emphasized that the type certificate reflects “China’s ability to independently develop and manufacture advanced civil turboshaft engines.” This statement underscores not only the technical achievement but also the symbolic value of the AES100 as a proof of concept for China’s broader aerospace ambitions.
“The successful development of a new helicopter engine is a crucial step toward China’s goal of technological self-sufficiency in aviation.”, Dr. Li Wei, Beihang University
The timing of the AES100’s approval is notable, coming just days after the United States announced a new round of export restrictions targeting jet engine-related technologies. These measures have increasingly limited China’s access to critical aerospace components, effectively accelerating Beijing’s drive for indigenous innovation. By developing the AES100 domestically, China mitigates the risks associated with supply chain disruptions and geopolitical leverage over key technologies.
Economically, the AES100 positions China to capture a larger share of the global helicopter market, valued at approximately $20 billion annually. With a domestically produced engine, Chinese manufacturers can offer more competitive pricing, reduce lead times, and ensure better integration with locally developed airframes. This could make Chinese helicopters more attractive to emerging markets in Asia, Africa, and Latin America, where cost and availability are significant purchasing factors. Furthermore, the AES100 supports the broader goals of the “Made in China 2025” initiative, which targets self-reliance in high-tech sectors. The government has reportedly invested over $5 billion in civil aviation R&D in recent years, and the AES100 represents a tangible return on that investment. It also enhances China’s ability to project power and respond to emergencies domestically and abroad, reinforcing its strategic autonomy.
Despite the progress represented by the AES100, China still faces significant challenges in achieving parity with global engine manufacturers. Turboshaft engines require high levels of precision engineering, rigorous testing, and long-term durability under diverse environmental conditions. Matching the performance, fuel efficiency, and certification standards of established players like Rolls-Royce or Pratt & Whitney remains a long-term objective.
Certification, in particular, is a critical area. While the AES100 has received a domestic type certificate, international certification is essential for export opportunities and global acceptance. This process involves extensive testing and compliance with standards set by regulatory bodies such as the FAA (Federal Aviation Administration) and EASA (European Union Aviation Safety Agency), which can take years to complete.
Additionally, the broader ecosystem of engine manufacturing,including supply chains for high-temperature alloys, precision components, and advanced coatings,is still developing in China. Continued investment in materials science, manufacturing technology, and workforce training will be necessary to sustain momentum and close the remaining gaps.
The AES100’s development is emblematic of a broader global trend: the pursuit of strategic autonomy in defense and aerospace technologies. As geopolitical tensions rise, particularly between the US and China, countries are increasingly seeking to insulate their critical industries from external disruptions. In this context, China’s progress in helicopter engine development may prompt similar moves by other nations to localize production and reduce reliance on foreign suppliers.
US export controls have had a paradoxical effect. While intended to limit China’s military and technological advancement, they have also galvanized domestic innovation. According to aviation analyst Mark Thompson, “US export controls have inadvertently accelerated China’s domestic innovation. While China still lags behind in some advanced engine technologies, these breakthroughs indicate a narrowing gap.”
From a market perspective, the emergence of a capable Chinese engine manufacturer introduces new competition for established firms. If China can achieve cost-effective production and secure international certifications, it could disrupt current market dynamics, particularly in price-sensitive regions. However, reputational factors, service networks, and long-term reliability will continue to influence purchasing decisions globally.
The AES100 helicopter engine marks a significant achievement for China’s aviation industry. Beyond its technical specifications, the engine represents a strategic pivot toward self-reliance, driven by necessity and supported by sustained government investment. It showcases China’s growing capabilities in aerospace engineering and signals its intent to become a formidable player in both civilian and military aviation sectors. Looking ahead, the AES100 is likely to be the first in a series of domestically produced engines aimed at reducing reliance on foreign technologies. While challenges remain in areas such as certification, durability, and global competitiveness, the trajectory is clear. China is investing in its future as an aerospace power, and the AES100 is a milestone on that journey.

Bye Aerospace Partners with Composite Approach for eFlyer 2 Production
Bye Aerospace teams with Composite Approach to produce composite structures for the eFlyer 2, targeting Spring 2026 first flight and FAA certification.
This article is based on an official press release from Bye Aerospace.
Bye Aerospace, the Denver-based developer of the all-electric eFlyer family of aircraft, has officially announced a strategic manufacturing partnership with Composite Approach. According to a press release issued on December 2, 2025, the Oregon-based manufacturer has been selected to produce the major composite structures, including the fuselage, wings, and empennage, for the first production-conforming eFlyer 2.
This agreement marks a significant transition for Bye Aerospace as it moves from the research and development phase into industrialization. The components manufactured by Composite Approach will be utilized to assemble the specific aircraft designated for the eFlyer 2’s inaugural flight as a production-conforming prototype. The company has targeted Spring 2026 for this milestone flight.
The partnership focuses on the “new-design” eFlyer 2, a term the company uses to distinguish the production-conforming airframe from previous proof-of-concept demonstrators. According to the company’s announcement, this airframe represents the design specifications submitted to the Federal Aviation Administration (FAA) for certification.
Rod Zastrow, CEO of Bye Aerospace, described the partnership as a critical step in the company’s roadmap. In the press release, Zastrow emphasized the shift toward physical production of the certified asset.
“This partnership marks a turning point for Bye Aerospace as we move from design to the physical production of our certified aircraft.”
, Rod Zastrow, CEO of Bye Aerospace
Composite Approach, located in Redmond, Oregon, brings decades of experience in advanced composite manufacturing. The firm is tasked with executing a “build-to-print” mandate, producing high-precision carbon fiber parts based on Bye Aerospace’s engineering data. Brian Harris, CEO of Composite Approach, noted in the release that the project involves “pushing the boundaries of composite technology” to meet the rigorous weight and aerodynamic requirements of electric-aviation.
The production-conforming eFlyer 2 is designed to meet the FAA’s Part 23 Amendment 64 certification basis, a performance-based regulation adapted to accommodate novel technologies like electric propulsion. The aircraft features an optimized aerodynamic design intended to maximize the lift-to-drag ratio, a critical factor for extending the range of battery-electric aircraft. According to technical details released by the company, the aircraft will be powered by the Safran ENGINeUS™ 100 electric motor. This propulsion system, combined with high-density battery packs, is engineered to support a flight endurance of up to three hours. This endurance target is a key differentiator in the electric flight training market, where current certified competitors often offer significantly shorter flight times.
The selection of Composite Approach signals that Bye Aerospace is attempting to de-risk its path to market by leveraging an established supply chain partner rather than building internal fabrication capacity from scratch. By outsourcing the major structural components, Bye Aerospace can concentrate its internal resources on systems integration, final assembly, and the complex FAA certification process.
The stakes are high for the Denver-based manufacturer. With a reported order backlog exceeding $700 million, the company faces pressure to deliver a certified product to flight schools eager to reduce operating costs. Traditional training aircraft burn leaded aviation fuel and require frequent engine maintenance; Bye Aerospace claims the eFlyer 2 will operate at one-fifth the cost of these legacy aircraft.
While the Spring 2026 target for the inaugural flight is ambitious, it represents the critical path toward final certification flight testing. If the eFlyer 2 can achieve its projected 3-hour endurance, it would offer a distinct operational advantage over existing certified electric aircraft, such as the Pipistrel Velis Electro, which is generally limited to local traffic patterns.
What is the difference between the “new-design” eFlyer 2 and previous versions? When will the production-conforming eFlyer 2 fly? Who is manufacturing the airframe? What is the primary market for this aircraft?

Eve Air Mobility Selects BETA Technologies for eVTOL Pusher Motors
Eve Air Mobility chooses BETA Technologies to supply electric pusher motors for eVTOL aircraft in a deal worth up to $1 billion over 10 years.
This article is based on an official press release from BETA Technologies and Eve Air Mobility.
In a significant move for the electric aviation sector, Eve Air Mobility has officially selected BETA Technologies to supply the electric pusher motors for its eVTOL (electric vertical take-off and landing) aircraft. The agreement, announced on December 2, 2025, represents a major step toward supply chain consolidation as the industry approaches commercialization.
According to the official announcement, this long-term agreement covers the supply of electric pusher motors for both Eve’s conforming prototypes and its serial production aircraft. Industry reports indicate the deal could be valued at up to $1 billion over a ten-year period, supporting Eve’s substantial order backlog of 2,800 aircraft.
The partnership marks a strategic pivot from vertical integration to a “best-of-breed” supply chain approach. By selecting BETA’s proven propulsion technology for forward flight, Eve aims to de-risk its certification timeline while retaining Nidec Aerospace as the supplier for its vertical lift motors.
To understand the significance of this supplier selection, it is necessary to examine Eve’s specific aircraft design. The company utilizes a “Lift + Cruise” configuration, which separates the propulsion systems used for hovering from those used for forward flight.
Under this architecture, the aircraft relies on two distinct motor types:
By separating these functions, Eve can optimize each motor for its specific phase of flight, high torque for the lift motors and high efficiency for the cruise motor.
According to technical details surrounding the deal, Eve is expected to utilize BETA’s proprietary motor technology, likely the H500A series currently used in BETA’s own ALIA aircraft. Key specifications highlighted in industry analysis include:
“These motors have been validated through thousands of flight hours on BETA’s own ALIA test aircraft, reducing the technical risk for Eve.”
, Industry Research Report
This agreement highlights a growing trend of cooperation between companies that might otherwise be viewed as competitors. Both Eve and BETA are developing their own electric aircraft, yet this deal positions BETA as a Tier 1 supplier to other Original Equipment Manufacturers (OEMs).
For Eve, the decision to source a critical propulsion component externally rather than developing it in-house offers clear strategic advantages. It allows the company to leverage BETA’s existing flight heritage, BETA has flown its motors extensively across the U.S., thereby potentially accelerating Eve’s entry into service, targeted for 2026.
With this selection, Eve has secured top-tier suppliers for the majority of its critical systems. The supply chain now includes:
The Era of “Frenemies” in Flight
We view this partnership as a maturing moment for the Advanced Air Mobility (AAM) sector. In the early days of the industry, many startups attempted to vertically integrate every component, from batteries to motors to airframes. Eve’s decision to purchase a motor from BETA, technically a competitor in the airframe space, signals that the industry is prioritizing certification speed and safety over proprietary exclusivity.
Furthermore, this deal validates BETA Technologies’ dual business model. By selling their propulsion tech to other OEMs, BETA diversifies its revenue streams beyond just operating its own ALIA aircraft. For investors, this reduces the “winner-take-all” risk often associated with new technology markets.
What is the value of the deal between Eve and BETA?
Reports estimate the agreement could be worth up to $1 billion over the course of 10 years, covering both prototype and serial production phases.
Does this mean Eve is stopping its own motor development? Eve is retaining Nidec Aerospace for its vertical lift motors. The agreement with BETA is specifically for the pusher motor used in forward cruise flight, allowing Eve to utilize off-the-shelf, proven technology for that specific function.
When is Eve expected to enter service?
Eve Air Mobility is currently targeting an entry into service (EIS) date of 2026.

Vertical Aerospace Expected to Generate £9 Billion Revenue by 2035
Frontier Economics study projects Vertical Aerospace’s £9 billion revenue by 2035, supporting UK jobs and contributing £3 billion annually to the economy.
This article is based on an official report released by Frontier Economics and commissioned by Vertical Aerospace.
A new economic impact study released in December 2025 suggests that the United Kingdom’s electric aviation sector is poised to become a significant contributor to the national economy. The report, titled “Next-Gen Aviation: Made in the UK” and conducted by Frontier Economics, uses Bristol-based Vertical Aerospace as a primary case study to demonstrate the financial viability of electric Vertical Take-Off and Landing (eVTOL) aircraft.
Commissioned by Vertical Aerospace, the findings argue that zero-emission aviation is transitioning from a future ambition to a current economic driver. The data highlights substantial potential for high-value job creation and export-led growth, particularly within the South West of England’s historic aerospace cluster.
The Frontier Economics report outlines aggressive growth targets for Vertical Aerospace over the next decade. According to the study’s projections, the company’s annual revenues could approach £9 billion by 2035. A significant portion of this revenue is expected to come from international markets, with the report estimating that approximately 90% of sales will be exports.
Beyond direct revenue, the report calculates the broader economic benefits for the UK:
The study emphasizes the role of “next-generation” aviation in sustaining the UK’s skilled manufacturing base. Vertical Aerospace currently employs 479 people. However, the report projects that direct employment at the company will rise to approximately 2,200 Full-Time Equivalent (FTE) roles by 2035.
Frontier Economics notes that these roles command a “wage premium,” with salaries at the company reportedly reaching up to twice the average for the region and the wider sector. This data is presented as evidence that the shift to green aviation supports high-quality employment rather than just volume.
In an effort to highlight the “Made in the UK” aspect of the industry, the report analyzes procurement data from 2022 to 2024. It finds that over 60% of Vertical Aerospace’s procurement was retained within the UK. This domestic spending reportedly supported roughly 720 additional jobs in the Bristol area and generated £21 million in local spending during that period.
“Vertical’s activities are well-aligned with the UK government’s priorities for industrial strategy, innovation, clean growth and defence… With sustained investment and supportive policy, Vertical could help shape the next generation of global aviation.”
, Andrew Leicester, Executive Director for Public Policy at Frontier Economics
The release of this data comes as the UK aviation industry works to align with the government’s “Jet Zero” strategy, which mandates net-zero aviation emissions by 2050. This strategy relies on three pillars: system efficiencies, Sustainable Aviation Fuels (SAF), and Zero-Emission Flight (ZEF).
The Frontier Economics report positions Vertical Aerospace within the ZEF pillar, arguing that new entrants are essential for modernizing regional hubs like the South West. This aligns with previous findings from the government-backed FlyZero project, which identified a “once-in-a-generation” opportunity for the UK to capture the global zero-emission aircraft market.
The Push for Policy Support
While the projected figures of £9 billion in revenue and £3 billion in GVA are impressive, we note that they remain projections contingent on certification timelines and market adoption. The timing of this report is likely strategic. By quantifying the return on investment for the taxpayer, specifically the £800 million in potential tax revenue, Vertical Aerospace is building a case for continued or increased government support.
As the industry faces high capital costs associated with certification and scaling manufacturing, demonstrating a tangible “ripple effect” in the local supply chain is a critical lever for securing grants and favorable policy frameworks. The report effectively argues that supporting eVTOLs is not just an environmental decision, but a necessary industrial strategy to prevent the UK’s aerospace sector from stagnating.
