80C High power aeroengine
The core of miniaturization pump
Ten years manufacturing experience of small Aeroengine
Cross border composing innovation movement!
Horizontal layout of 80C Aeroengine
Realize the ultra-thin and miniaturization of pump body

Ceramic cylinder, 300hr high power test
forced water cooling of low pressure balance tube

Ten years of aero engine technology accumulation
Fully autonomous design and manufacturing

Integral aviation aluminum alloy, precision machining
CNC precision core components, strict assembly process

80C high-performance UAV Engine power assembly is adopted, with air-cooled and forced water-cooled composite heat dissipation, meeting the ultra-long continuous working time. The engine has been tested for more than 300hr high-speed uninterrupted operation, with a maximum speed of 9000 rpm and an output power of 10 horsepower. It has an engine overheating protection system.
80C horizontal engine, built-in high-intensity magnetic power generation system, can continuously output 14.5V and 60W stable voltage in the working process, ensure the power consumption of external equipment, and charge the starting battery, which is an outstanding progress brought by technical advantages.
The durability of 80C horizontal engine comes from the specially designed low-pressure balance tube water-cooling technology. The continuous water flow ensures that the engine does not suffer from cylinder pulling and temperature overload caused by overheating. This inherent advantage ensures that each pump has incomparable durability.
