AAI Flies Aerosonde(R) Mark 4.7 Aircraft with Heavy Fuel Engine

A heavy fuel propulsion system is a critical capability for both U.S. and international armed services. Maritime forces like the U.S. Navy and Coast Guard benefit because kerosene-based fuels are less flammable than gasoline in shipboard environments. Services with both land- and air-based missions, such as the U.S. Army, can embrace a "one fuel forward" concept by transitioning to a single fuel for all of their assets, minimizing cost and logistics.
