Engine Description
The engine is a turbojet of a single shaft design specifically designed to power RC aircraft. The
engine starts automatically thanks to an installed electric starter situated in the front. The
starting sequence is controlled by an electronic unit that initiates the starting sequence and
controls the parameters of the engine within the design limits.
The engine uses a system of direct liquid preheating, ignited by a long life ceramic glow plug
situated inside the engine. After the initial preheat the liquid fuel is gradually introduced. The fuel
should contain a small percentage of oil and uses part of this fuel to lubricate its two ceramic
high speed bearings.
The fuel for the engine is provided from an external fuel tank through a small electrical pump
that uses a three phase brushless motor. The engine speed between idle and maximum is
