Lightweight Rotary Wankel APU with 11kW Generator.
Ideal for hybrid-electric multicopters as LiPol Battery replacement.
Key technologies
Highly effective for sustained operation at constant speeds. Built for Multicopters and VTOLs.
Advanced electronic heavy fuel injection system with an ECU-controlled e-supercharger maintaining optimal intake pressure. Ultrasonic fuel injectors with variable duty cycles ensure precise 2-5 nm atomization across all temperatures and altitudes.
With a continuous electrical power output of 11 kW, peaking at up to 16 kW, the RW79 provides a robust power source. Consumers can connect through a distribution controller featuring four independent groups, each with four channels, totaling 16 channels, all operating at 48V. These channels can be combined into groups of 96, 144, 192, or 384 volts, allowing for versatile power configurations. Each channel group offers independent control, a prioritized overload protection system, power balancing, and power limitation features, ensuring optimal performance and safety.
The forced-air cooling system directs airflow through the generator stator coils, removing heat before centrifugal rotor blades accelerate it through optimized channels on the engine housing. These channels manage Wankel-specific heat distribution. Heated air is expelled around the exhaust system, preventing engine compartment heating and mixing with exhaust gases to reduce IR visibility.
Materials and technologies: The engine casing is milled from dural alloy forging. The combustion chamber (stator) is formed from a thin cast-iron sleeve and cast-iron side walls to the reverse side of which labyrinth cooling channels are connected. The rotor is hollow, cooled by the fuel mixture, and made from an aluminum forging. Apex channels are electroplated. Seal apexes are tungsten carbide, and sidewalls are ground and anti-seize coated. The crankshaft and internal gears are forged steel. Bearings operate on polished and hardened surfaces. The outer surfaces of the engine are hard anodized and primed. All fasteners are stainless steel or titanium. All connectors are sealed, mil-spec.
We offer an Engineering Developer's Kit (Demo Kit), which includes an engine mounted on a subframe, with all pumps, filters, an ECU, PDU (Generator Rectifier), Starter/Generator, Starter Battery and a full wiring kit— everything needed for startup and testing. Demo-Kit can be mounted on a dyno stand or integrated into your prototype. The package also includes control software, documentation, including an API and necessary source codes.
