Turbocharged fanprop

The unique turbofan prop engine illustrated below is a product of King Yarl's incessant work on many projects. The projects always overlapped. The King also saw the engine applied in his country's own aircraft designed from scratch. (Unlike the Vandal aircraft, which use structural concepts developed jointly with US manufacturers) These indigenous aircraft comprised unusually fast and maneuverable Coast Guard patrol-gunship planes, a large attack gunship plane and a utility heavy lifter plane.

The engines are unique because they preserve efficiency of a turboprop at any speed and altitude, allowing for controlling individual speeds of turbines, propellers, and propeller pitch. Another unique feature of the engine is having an equivalent of a turbocharger and a variable afterburner.
