ABSTRACT:
A ducted fan type model aircraft power plant having a mounting for a one cylinder internal combustion model aircraft engine. The preferred engine utilizes a special vertically oriented carburetor. A duct is supported by a set of stators having an aerodynamic shape for straightening airflow through the duct. A fan having seven identical individual replaceable blades is disposed at the front of the duct and directly driven by the engine. One stator is adapted to essentially enclose the vertical carburetor and to smoothly direct the airflow from the fan around the carburetor to the engine cylinder for cooling. The stator has an opening to the carburetor air inlet for providing air under pressure thereto. The stator shapes cooperate with the duct and aft fairings of the power plant to deliver a smooth airstream having a uniform non-turbulent flow to produce a maximum propulsive efficiency.
