Heavy-Fuel Range for Small Drones, at Attritable Cost

An affordable hybrid propulsion module that runs small unmanned systems on JP-8 and other heavy fuels — extending range and endurance far beyond batteries, from a domestic, mass-producible supply base.

What It Is

[Atomizer-on-engine — Fig 2 — Image to be uploaded]

Small unmanned systems in the 5–20 kg class are capped by their batteries — roughly an hour of endurance — while the few small engines that burn military heavy fuel cost tens of thousands of dollars each. This is a propulsion module, not a vehicle: a compact two-stroke heavy-fuel engine paired with a generator that recharges the battery in flight, so an integrator can drop it in where a battery pack used to be. Ultrasonic piezoelectric atomization is the enabling idea — it prepares cold, viscous fuel finely enough to burn in a small high-speed engine, which is what lets the platform run on a single forward fuel.

Key Capabilities

• • Single forward fuel — JP-8, JP-5, F-24, Jet-A1, or diesel
• • Range and endurance well beyond battery-electric in the same class
• • ~1.2 kg module, ~750–860 W shaft power at cruise, sized for the 5–20 kg class
• • Engine displacement scalable to the platform and mission
• • Built on mature, domestically produced components — aligned with Section 889

Development Status

The module is in active development; performance figures are engineering targets pending integrated test. We’re seeking platform integrators and development partners.
