VH-3 185 kW

What if you could have a 555 kW-hr battery pack with 1200 wh/kg energy density now and not decades in the future?

The VH-3-185 kW hybrid powerplant is a game-changer for commercial and military aviation, unlocking new mission capabilities across a range of applications, such as urban air mobility and regional cargo transport to tactical defense and unmanned aerial systems. Leveraging insights from two prior generations of VerdeGo Aero hybrid systems, the VH-3-185 sets the industry standard as the best piston-powered hybrid powerplant on the market. Our powerplant features patent-pending elements that make it more efficient, reliable, and flexible for applications in a wide array of market segments. The result is a next-generation powerplant providing 185 kW of continuous electrical power output in a 650 lb package with exceptional fuel efficiency of 0.37 lb/HP-hr.

With a focus on simplified electronics and engine operation, this powerplant is gaining traction with commercial and military customers, and its predecessor is already in flight testing in a crewed aircraft applying hybridization and distributed electric propulsion to achieve new levels of performance and efficiency.  

Development of the VH-3 is supported by multiple U.S. Air Force and NASA programs involving  multiple airframe applications across different markets. A trusted partner of the Air Force, VerdeGo was awarded a program to develop and test the first production-intent VH-3 prototype, accelerating its path toward operational deployment.
