Dual-Rotor Turbocharged Engine Ignition Marks New Milestone for Low-Altitude Mobility

Harbin Dongan Auto Engine has reached an important development milestone after successfully igniting its first dual-rotor turbocharged engine, known as the R10TE. The project was jointly engineered with AVL and builds upon the company’s earlier R05E single-rotor platform. Designed around a 1.0-liter dual-rotor turbocharged architecture, the new engine is intended to support future high-power mobility applications. According to the company, the R10TE is expected to enter mass production in 2028 as development activities continue toward commercialization.

The R10TE incorporates several advanced engineering features aimed at enhancing performance and efficiency. The engine utilizes an 11.5:1 compression ratio, a twin-channel supercharger configuration, and a composite-material sealing system developed for rotary engine applications. These technologies contribute to a power-to-weight ratio exceeding 1.8 while enabling output of more than 120 kW at a rated speed of 5,500 rpm. The company has also strengthened its intellectual property position, filing more than 70 patent applications associated with rotary engine innovations and related technologies.

Dongan Power indicated that its rotary engine platform has attracted interest from multiple organizations operating in emerging mobility sectors. Discussions have been conducted with companies including XPeng AeroHT, Changan Automobile’s flying car division, DJI, and Harbin Aircraft Industry Group. The R10TE has been specifically developed to address the growing demand for high-power propulsion systems supporting low-altitude economy applications, a segment that includes next-generation aerial mobility platforms and other advanced transportation solutions.
