***** Will it work or not? ***** Please read. This is another "I always wanted to try this" episode from Mr. Herbert's science class. My theory is, just like jet turbines, compressing the air in stages will increase the final output. So by adding a Ducted Fan "compressor" to the intake, the main fan should work more efficiently. This test idea was borne when my long time friend, Bud Parriott laid the idea down of adding a second ducted fan to "feed" the main ducted fan like we did on his Space Shuttle model long ago.. In it he used a gas ducted fan in the nose to supply air to the main engine. I was intrigued for sure with trying it with electric ducted fans. Back when we were first experimenting with gas ducted fans, like on my Byron F-16, we had to cut a big "Cheater Hole" in the lower fuselage to get more air to the fan. Otherwise, the fan would "cavitate" the air and it would not have enough power to fly. The standard intake was just not big enough to get enough air. I decided to use my old NitroPlanes Art Tech F-15 for the test. There is lots of room on the back. This is the plane that I inadvertently crashed a while back, when I shut the transmitter off while trying to trim it. It is a little banged up, but it works. It also was not very fast....until now. Remember, if it sounds stupid, but it works, it ain't stupid. Thanks for watching and subscribing. Dave Herbert Academy of Model Aeronautics # 8221 Contest Director, Leader Member, Scientific.
