VerdeGo testing shows it won't need to compromise on performance

VerdeGo is in the process of shifting its R&D program over to using SAF to validate compatibility with 30/70 and 50/50 blends of SAF/jet fuel, along with 100% SAF for the capability to achieve zero net carbon ops.

The VH-3 hybrid powerplant has completed a rigorous testing programme which, says VerdeGo, proves it doesn't need to compromise between performance and sustainability.

The company has completed more than 500 full scale tests of its prototype hybrid systems since mid 2020 and during endurance tests of up to six hours in length, fuel input and electrical output were directly measured, validating the efficiency of its hybrid powerplant architecture. Testing was performed during 85 degree F to 89 degree F days with all cooling systems operational to enable full power output at zero forward airspeed, to simulate hover conditions. It says the resulting specific fuel consumption was 227g/kWh at 150kW of output, with a very flat efficiency curve that demonstrates high efficiency during all phases of a typical flight.

VerdeGo says the VH-3 is suited for customers such as the Jaunt Air Mobility Hybrid. The specific fuel consumption of competing turbine hybrid approaches is estimated to be between 0.55 and 0.65 lb/hp hr which is 49% to 76% higher than the demonstrated efficiency of VerdeGo's hybrid powerplant.

Conformal VH-3 systems for non-certified applications are projected to be available to customers in late 2023 with certified powerplants available in 2025. VerdeGo's has adopted a no compromises approach to electrification and says this will accelerate the electrification of flight and will lead to faster progress towards aviation sustainability.

Dave Spitzer, VerdeGo Aero's VP of product development says: “When we test our hybrid powerplants, we directly measure fuel going in and kilowatt hours of electrical power flowing out, it doesn't get simpler than that. All of the cooling and auxiliary systems are present, so what we are reporting is what our customers should see in service.”

Jaunt CCO Simon Briceno adds: “The twin VerdeGo VH-3 installation in the Jaunt Hybrid Aircraft will provide unprecedented mission capability and efficiency for customers operating fleets of our aircraft.”
