Aero Engine Corp of China (AECC) plans to obtain type certification for the AEP100 turboprop engine in 2027. The engine was designed to equip the W5000, a twin-engine cargo drone with a capacity for 5 tons and a range of 2,600 km, which, after its maiden flight, will become the world’s largest transport drone. China wants to eliminate dependence on foreign engines in the general aviation sector, where it has only a few thousand aircraft compared to over 275,000 in the United States.
The China is building an aircraft engine that is not just another aeronautical engineering project: it is a declaration of technological independence. The AEP100, developed by AE General Aviation Power Tech, a subsidiary of AECC (the country’s main aircraft engine manufacturer), has entered the final phase of the type certification process with the Civil Aviation Administration of China and is expected to receive approval in 2027. But what makes the project revealing is not the engine itself: it is the aircraft for which it was designed.
The AEP100 will equip the W5000, a twin-engine turboprop cargo drone that, when it takes off, will be the largest transport drone in the world. The W5000, developed by the Chinese startup Air White Whale, has a maximum takeoff weight of 10.8 tons, a payload capacity of 5 tons, an internal cargo space of over 65 cubic meters, and a range of 2,600 kilometers on a single flight. With a length of 22.9 meters and a wingspan of 22.7 meters, the aircraft is larger than many manned transport planes and does not require a pilot to operate.
What is the AEP100 engine and why does it matter to China
According to information released by China Daily, the AEP100 is a state-of-the-art turboprop engine that China is developing to end its dependence on foreign engines in the general aviation sector. The project’s general manager, Yuan An, states that the AEP100 demonstrates superior performance to foreign competitors in various technical indicators, including power, stability, and efficiency. The engine was installed in W5000 prototypes for ground tests over the past year and maintained consistent performance throughout the period.

Type certification is the mandatory regulatory approval for aeronautical components in China and confirms that the product meets the required safety, noise, and emissions standards. The AEP100’s process is progressing faster than that of the AES100 turboshaft engine because both use the same core engine, which significantly reduces validation procedures. The expectation is that the W5000 will make its maiden flight soon, also marking a milestone for the AEP100.
The W5000 drone that will become the world’s largest
The W5000 is neither a recreational drone nor surveillance equipment: it is a heavy transport aircraft designed to deliver 5-ton payloads over distances of up to 2,600 kilometers without human intervention. After its maiden flight, the W5000 will replace the Norinco Luca as the most powerful transport drone on the planet, consolidating Chinese leadership in a segment that uniquely combines aviation, automation, and logistics.
The dimensions of the aircraft are impressive: 22.9 meters long, 22.7 meters wingspan, and an internal cargo volume exceeding 65 cubic meters. For comparison, the W5000’s cargo space is larger than that of many delivery vans used on the ground, but with the advantage of flying over mountains, rivers, and regions without roads. China designed the drone to solve a problem faced by its 1.4 billion inhabitants: delivering supplies to remote areas that lack road or rail infrastructure.
The hidden ambition: why China wants 275,000 aircraft
The numbers reveal the true scale of Chinese ambition. The United States has over 275,000 general aviation aircraft, while China has only a few thousand, according to Yuan An. This disparity indicates a virtually untapped domestic market that, if even partially filled, would generate demand for hundreds of thousands of engines in the coming years.
Yuan precisely explains the logic: “When emergency supplies or high-value goods need to be delivered to remote mountainous areas, islands, and regions without expressways, general aviation aircraft become the most viable solution.” Given that each aircraft is typically equipped with one or two engines, market demand will be substantial. The AEP100 and its variants are China‘s answer to meet this demand without relying on Western manufacturers like Pratt & Whitney or Honeywell.
The end of reliance on foreign engines
The project’s general manager’s statement is categorical: “The AEP100 and its variants will end the heavy reliance on foreign engines in China’s general aviation sector.” The statement carries geopolitical weight because aeronautical engines are one of the few technological segments where China still depends on Western suppliers, and autonomy in this area removes a strategic vulnerability that adversaries could exploit with sanctions or export restrictions.
The strategy is not limited to the AEP100. AECC engineers are also designing hybrid engines with powers ranging from 200 to 1,000 kilowatts, signaling that China wants to master both conventional fossil fuel and electrified propulsion. Several customers have already expressed interest in the hybrid engines, indicating that the Chinese market is prepared to absorb a new generation of aircraft that combines energy efficiency with heavy payload capacity.
What the project means for the global technology race
The AEP100 and W5000 do not exist in a vacuum: they are part of a technology race where China seeks leadership in sectors ranging from semiconductors to autonomous aviation. A country that can manufacture its own aeronautical engines and the world’s largest cargo drones reduces reliance on supply chains controlled by geopolitical adversaries and gains military and logistical capabilities that few nations possess.
For the West, the certification of the AEP100 in 2027 and the maiden flight of the W5000 will be milestones confirming that China has not only caught up with traditional aeronautical engine manufacturers but is surpassing them in specific segments like autonomous cargo aviation. The true ambition behind the project is not just to fly without a pilot: it is to fly without needing anyone.
