The information provided here is as accurate as possible; however, eVTOL information from China is sometimes sparse, incomplete or conflicting. China is promoting what they call the "low-altitude economy" — a new push for general aviation — which includes both crewed and uncrewed passenger and air cargo eVTOL aircraft.

Based in China, the Beijing Shenmou Aircraft Technology Co., Ltd is in the business of designing and manufacturing passenger and air cargo hybrid-electric vertical takeoff and landing (VTOL) aircraft for advanced air mobility (AAM). In May 2025, the company unveiled their HW450H heavy-lift and long-range VTOL concept design aircraft. The English name of the company is SYSMO.

HW450H heavy-lift long-range passenger and air cargo hybrid-electric VTOL concept design aircraft
The HW450H is a heavy-lift and long-range passenger and air cargo hybrid-electric VTOL concept design aircraft. The aircraft has one pilot, carries three passengers and their luggage. If the aircraft is remotely or piloted autonomously, the aircraft can carry up to four passengers and their luggage. The aircraft can be configured into an emergency medical services (EMS) aircraft, an air cargo aircraft and into multiple other configurations for air missions. The company has designed the aircraft to be modular in design which allows for component swapping to support various mission profiles while foldable wings and arms enable compact storage and transportation.

The maximum speed of the aircraft is estimated at 320 km/h (199 mph), has an predicted range of 820 km (510 miles) and has a calculated maximum altitude of 6,000 m (19,685 ft). It has been reported the aircraft has 12 tilt-propellers, 12 electric motors and is powered by a hybrid-electric power source. However, upon looking at the aircraft's concept drawing, the aircraft could have four tilt-props and eight VTOL-only propellers.

The empty weight of the aircraft has been designed to be 750 kg (1,654 lb), with an expected maximum payload weight of 450 kg (992 lb) and has a target maximum takeoff weight of 1,200 kg (2,646 lb). The aircraft has tandem wings, two vertical stabilizers and has four fixed landing struts. It has been reported the aircraft will have gull-wing doors and a rear access door. The fuselage will be made from carbon fiber composite to give the aircraft a high strength to low weight ratio.

The company foresees their aircraft to be used for mountain operations, maritime operations, emergency rescue, remote air cargo transport, low-altitude tourism and advanced air mobility (AAM).

It is important to remember that all concept design aircraft specifications are estimated and can or will change as prototypes and production models are made, tested and flown with real world avionics, components and payloads.

Specifications:

• Aircraft type: Passenger and air cargo eVTOL concept design aircraft
• Piloting: 1 pilot, remote or autonomous
• Capacity: 3 passengers and their luggage or air cargo. The aircraft's interior can be reconfigured for multiple types of air missions.)
• Maximum speed: 320 km/h (199 mph)
• Range: 820 km (510 miles)
• Maximum altitude: 6,000 m (19,685 ft)
• Empty weight: 750 kg (1,654 lb)
• Maximum payload weight: 450 kg (992 lb)
• Maximum takeoff weight: 1,200 kg (2,646 lb)
• Propellers: 12 propellers (It has been reported there are 12 tilt-propellers.)
• Electric motors: 12 electric motors
• Power source: Hybrid-electric power source
• Fuselage: Carbon fiber composite with gull-wing doors and a rear access door
• Windows: Panoramic wrap around windows allowing forward, left and right visibility for spectacular views with a solid roof above the passenger compartment
• Wings: Tandem wings
• Tail: 2 vertical stabilizers
• Landing gear: 4 fixed struts
• Safety features: Distributed Electric Propulsion (DEP) uses multiple propellers or electric ducted fans, each powered by electric motors, to increase safety through redundancy. If one or more components fail, the remaining ones can still ensure a safe landing. There are also redundancies of critical components in the sub-systems of the aircraft providing safety through redundancy. Having multiple redundant systems on any aircraft decreases having any single point of failure.
