First Test of EDF Jet Motor Prototype


This is a scaled-down working model of an Electric Ducted Fan Jet Motor with Thrust Vectoring control surfaces. I constructed it out of 5mm Foam Board typically found in the arts & crafts section of local store, poster board, white Duck brand Duct Tape, hot glue, and a modified cooling fan recovered from an Original Xbox gaming console. The purpose of making this model was first and foremost to see if it would actually work. I am working on a project that uses EDF Units and Brushless Inner-running motors as a method of propulsion. Before I invested in a factory made EDF Unit and motor, I thought it would be best to construct this prototype for testing. This fan is not powerful enough to provide the thrust needed for my project. It is merely a means to test the Thrust Vectoring control surfaces.

This prototype was designed with a compass, square, and metric ruler, remnants of my days in mechanical drawing class.


                What is Thrust Vectoring?


Thrust vectoring, also thrust vector control or TVC, is the ability of an aircraft, rocket, or other vehicle to manipulate the direction of the thrust from its engine(s) or motor(s) in order to control the attitude or angular velocity of the vehicle.


For aircraft, the method was originally envisaged to provide upward vertical thrust as a means to give aircraft vertical (VTOL) or short (STOL) takeoff and landing ability. Subsequently, it was realized that using vectored thrust in combat situations enabled aircraft to perform various maneuvers not available to conventional-engined planes. To perform turns, aircraft that use no thrust vectoring must rely on aerodynamic control surfaces only, such as ailerons or elevator; craft with vectoring must still use control surfaces, but to a lesser extent. - From Wikipedia, the free encyclopedia 









The design of an EDF unit has to be exact. If the circumference of the duct is not perfectly circular, this can cause a decrease in thrust and possibly fan blade and/or EDF unit failure. The purpose of these video tests were to see if the fan blades would make contact with the duct and to see any vibrations. I used an E-cigarette for the smoke test, so I should have said vapor test.
