There's Nothing Mysterious About Ducted Fan Models!

Free Flight Scale Plane

Wingspan 26 3/4”

Engine .049 Ducted Fan

By WAYNE A. SCHINDLER

   After studying the various articles on ducted fan propulsion and finding little useful information for converting to individual use, we decided to set up a series of experiments that would show us exactly how to go about designing a practical system.

 The first step was to decide on the general type of ducted fan propulsion to use ‑the wing root intake system or the straight‑through system. Since most present ­day jet aircraft have wing root intakes, we decided to develop a system that utilized these intakes. This would enable us to keep the nose of the model free for radio control equipment on a larger model. This system could also be used for U ­control scale or Navy Carrier Event models or Half‑A free‑flight scale craft.
