ANNOUNCEMENT - the engines have been flown by a Nigerian model flyer (Zortrax M200 printed) - see photos - delighted and Congratulations to Tommy Mubarak for such a fine job. Link to YouTube. https://www.youtube.com/watch?v=Oow1ppcij9o Tested jet engine housing for edf ducted fans. Model file is 10x actual size (to solve an issue with Setchup) - so scale down to 10% for 70mm EDF units. Last photo is the plane the model was based on - the Britten Norman Islander ducted fan version. The fan units were off eBay - look up '2x 70mm Duct Fan 3000KV motor + 2x Mystery 60A brushless ESC+ Program Card B' This is my very first Thingiverse upload. Youtube Video here https://www.youtube.com/watch?v=J75adKruarc&t=7s Engine casing has been tested on the 70mm EDF units they were designed for - but I see no reason they couldn't be scaled for other sizes of EDF units I cut the lugs off the EDF unit and superglue it in to the casing.... Mine were made on Zortrax M200 and M300 printers. Note... A ducted fan is a propeller in a straight sided duct, a turbofan jet engine generates a back pressure behind the fan which is converted in to thrust by the internal geometry of the engine, including the exhaust nozzle - we tried a straight through 'ducted fan' set up with the same fan units and they didn't work as well, so this design is working just like a full size turbofan - the only difference is the replacement of the gas engine that turns the fan with an electric motor. Nearly all the thrust from a typical passenger jet airliner engine is from the big fan just shoving air straight out the back through the engine nozzle geometry, just like this one :)
