When people picture aerospace, they picture orbit — rockets climbing through the atmosphere toward the black. But some of the most consequential growth in the aerospace economy is now happening in the opposite direction: downward, into the layer of sky closest to the ground. The "low-altitude economy" — drone logistics, electric air taxis, aerial inspection and surveying, agricultural aviation, emergency response, and the vast supporting infrastructure behind them — is turning airspace that has sat largely empty for a century into a working industrial layer, typically defined as the airspace below about 1,000 meters, with the bulk of commercial activity concentrated under 300.
It is also, increasingly, an equipment story: new airframes, propulsion systems, batteries, avionics, ground stations, and traffic-management platforms that did not exist a decade ago. Many of these technologies and the suppliers behind them will be on display at The 10th Shanghai International Aerospace Technology and Equipment Exhibition 2027 (AIREXPO 2027), taking place July 7–9, 2027, at the Shanghai New International Expo Center — a timely vantage point on the newest layer of the aerospace economy.
The low-altitude economy is unusual: it was named into existence by policy before most people had heard of it. In 2024, China's Government Work Report listed the sector alongside commercial spaceflight as one of the country's designated "new growth engines," and the country's top macroeconomic planning agency has since established a dedicated office for it. Provincial and municipal governments across China have followed with implementation plans, flight-corridor designations, and special funds, according to public reports.
The commercial base underneath the policy is real. Industry research groups commonly sized China's low-altitude economy in the hundreds of billions of yuan annually, and the projections that circulate in official-adjacent analyses point to trillion-yuan scale in the middle years of this decade and several times that by 2035. Shenzhen alone is home to more than a thousand drone-related companies, and Chinese manufacturers dominate the global market for small commercial drones. Guangzhou, Hefei, Chengdu, and the Yangtze River Delta cities have each built clusters around eVTOL developers, drone operators, and their component suppliers — a geography that matters for anyone sourcing into this industry.
What makes the sector more than a niche is the breadth of jobs being flown today. Agriculture, power-line and solar-farm inspection, mapping and surveying, emergency delivery, firefighting support, and aerial filming are established, revenue-generating applications. Food and parcel delivery by drone now runs on regular scheduled routes in several Chinese cities. The low-altitude economy is not a plan for the future; it is an operating industry scaling up.
The airframe landscape is sorting itself into recognizable classes, each with its own certification path and economics.
Multirotor logistics drones carry payloads of a few kilograms over short urban hops. They are cheap, numerous, and increasingly autonomous, and their constraint is not performance but airspace allocation and noise.
Heavy cargo drones and ton-class eVTOLs are the workhorses in development — platforms designed to move hundreds of kilograms or more between logistics hubs, islands, and industrial sites. According to public announcements, a Chinese ton-class cargo eVTOL collected a type certificate in 2024, a first for that category, and several developers are flying prototypes at commercial scale.
Passenger-carrying eVTOLs mark the frontier. A Chinese developer received the world's first type certificate for an autonomous, passenger-carrying electric vertical-takeoff-and-landing aircraft in 2023, followed in due course by production and operator approvals — meaning scheduled, ticketed autonomous air-taxi flights are no longer a concept but a regulatory category. Internationally, developers in the United States and Europe are progressing along parallel certification pathways, generally with onboard pilots. The result is two philosophies racing on two tracks — autonomous-uncrewed in China, piloted-crewed in much of the West — and both converge on the same industrial demands: energy-dense batteries, redundant electric propulsion, lightweight structures, and certifiable autonomy.
Here is the counterintuitive part: the hardest problem in the low-altitude economy is not building vehicles. It is building the system around them.
Ground infrastructure comes first. Aircraft that take off and land vertically need somewhere to do it — vertiports, rooftop pads, charging stations, and maintenance facilities arranged into networks. Shenzhen has announced plans for a municipal network of more than a thousand low-altitude takeoff and landing points, according to public reports, and other cities are drafting their own. Each pad is a construction project; each network is an urban-planning exercise.
Airspace management is the deeper challenge. Thousands of autonomous aircraft cannot share low-altitude airspace on voice radio and eyeballs; they need a digital traffic layer — automated flight-plan filing, real-time deconfliction, remote identification, and dynamic corridor management. China's approach is to build this "digital infrastructure first," with unmanned traffic management platforms and dedicated low-altitude service networks under construction at national and municipal levels. Telecommunications operators are additionally trialing 5G-Advanced networks whose base stations double as low-altitude sensing infrastructure, extending coverage to the 300-meter layer that conventional networks were never designed to serve.
Weather, noise, and public acceptance complete the picture. Low-altitude operations are far more exposed to wind, rain, and icing than airline routes; communities are sensitive to drone buzz over residential areas; and operators must earn the social license that comes from years of safe flying. None of these is a technical showstopper, but all of them shape deployment speed — and all of them generate demand for equipment: weather stations, acoustic measurement, simulation platforms, and test infrastructure.
Airworthiness certification is the crucible of this industry. A passenger eVTOL must demonstrate structural integrity beyond a conventional aircraft's usage envelope — thousands of daily takeoffs and landings, battery thermal safety, motor-out contingencies, and software reliability across millions of autonomous flight hours' worth of evidence. Regulators in China, the United States, and Europe are writing the rulebook in real time, and the manufacturers who certify early acquire a moat that capital alone cannot buy.
The second-order effects are significant. Certification drives the market for test equipment — iron-bird rigs, battery abuse testing, fatigue frames, environmental chambers — and for the documentation, simulation, and data-management tools that assemble the safety case. Insurance and liability frameworks are being built atop these certificates. For equipment and service providers, regulation is not friction; it is the product roadmap.
Follow the money down the stack, and the low-altitude economy reveals itself as a supply-chain story:
Propulsion: high power-to-weight electric motors, motor controllers, and the thermal management around them — physics shared with electric vehicles but specified to aviation standards.
Energy: high-energy-density battery cells and packs, battery management systems, and fast charging; the industry is watching semi-solid-state and other advanced chemistries move from announcements to airframes.
Structures: carbon-fiber composites and automated composite manufacturing, because every kilogram of airframe is a kilogram of battery that does not have to be carried.
Avionics and autonomy: flight-control computers, inertial and GNSS navigation, detect-and-avoid sensing, and the software stack that makes uncrewed flight safe in cluttered airspace.
Ground and test equipment: pads and charging networks, weather and surveillance sensors, test rigs, and simulation environments.
Two supply-chain adjacencies stand out. First, the electric-vehicle and consumer-drone industries have already industrialized most of these components — meaning the marginal cost of entering aerospace-grade supply is lower than in any previous aviation era, and Chinese suppliers sit near the center of both. Second, the connection to space: satellite constellations in low Earth orbit are being positioned as connectivity for beyond-visual-line-of-sight drone operations, and the autonomy stacks, composite manufacturing techniques, and test regimes of drones and satellites increasingly borrow from each other. The low-altitude economy and the orbital economy are not separate industries; they are two curves of the same aerospace upturn.
That convergence is what makes AIREXPO 2027 an efficient waypoint for the industry. The 10th Shanghai International Aerospace Technology and Equipment Exhibition 2027, taking place July 7–9, 2027, at the Shanghai New International Expo Center, will bring together the full span of the aerospace equipment ecosystem — launch vehicles and satellites, aviation platforms and their suppliers, and the low-altitude technologies now bridging the two: eVTOL airframes, propulsion and battery systems, flight-control and traffic-management platforms, composite manufacturing equipment, and test and certification infrastructure.
Shanghai itself is a fitting host. The Yangtze River Delta hosts one of the country's densest concentrations of aerospace, robotics, electronics, and precision-manufacturing capability — the exact supplier base the low-altitude economy needs as it moves from demonstration to deployment. For procurement teams, the exhibition compresses months of supplier discovery into three days; for technology companies on the outside of aerospace looking in, it is the lowest-friction entry point to a market being built in real time.
The next layer of the aerospace economy will not be built in orbit first. It is being assembled at 300 meters and below, pad by pad, corridor by corridor, certificate by certificate — and July 7–9, 2027, is when the industry gathering to build it convenes in Shanghai.
