Frequently Asked Questions About UAV Engines
A heavy-fuel engine runs on kerosene-based fuels such as JP-8, JP-5 or Jet A rather than gasoline. Military operators favor them because a single fuel supply serves aircraft, vehicles and generators, and because heavy fuels are far safer to store and handle aboard ship.
HFE International designs and manufactures heavy-fuel and multi-fuel propulsion systems for unmanned aircraft. The range covers EFI UAV engines, MIL-SPEC engines, GenPod field-swappable propulsion units, Wankel rotary engines, power management systems, servos, sensors and UAV ground support equipment.
Electronic fuel injection meters fuel electronically against engine and air data, where a carburetor relies on airflow through a fixed jet. EFI starts and runs reliably across altitude and temperature swings without manual adjustment, holds a more consistent air-fuel ratio, and typically burns less fuel for the same power.
A GenPod is a complete line-replaceable propulsion unit from HFE International, combining engine, mounts, fuel system, ignition and generator in one sealed assembly. A field crew swaps the entire pod instead of repairing an engine on the flight line. GenPod is available in 70, 100, 120 and 150 configurations.
Yes. HFE International is a business-to-business supplier to UAV manufacturers, aerospace integrators, defense contractors and government agencies worldwide, including the United States and Canadian Armed Forces. We hold AS9100D and ISO 9001:2015 certification.
The DA series of EFI UAV engines runs from the DA-35 through the DA-50, DA-70, DA-100, DA-120, DA-150 and DA-215. MIL-SPEC variants, Wankel rotary engines and multi-fuel engines are also available, spanning roughly 15 to 40 brake horsepower with generator options across most of the range.
