The RW1-79 is a Wankel-based auxiliary power unit (APU) with an integrated 11kW generator, designed for fixed-wing UAVs with high electrical load requirements as well as VTOL aircraft. It utilizes advanced electronic fuel injection and proprietary ultrasonic fuel injectors to ensure consistent performance around a variety of operating temperatures and altitudes.
The unit delivers a robust power output of 11kW continuous and 16 kW peak. A distribution controller partitions this power into four independent groups, each with four channels, all operating at 48V. These channels can be combined into groups of 96, 144, 192, or 384 volts, allowing for versatile power configurations.
The rugged and lightweight unit features ultra-modern materials and manufacturing processes that have eliminated issues traditionally seen with Wankel rotary systems. The outer surfaces have been hard anodized and primed, and all connectors are sealed and mil-spec.
