    Ducted fan blade design

    Ducted fan efficiency if engine is taken out of the equation (pure electric case)

    Hey there Starman- It happens to be that I acquired 2 Turbofan Blades from a LearJet Engine during my A&P Training Class back a while ago. THe Idea I have is to recreate these Blades with Carbon FiberGlass making them extremely ridgid and significantly lighter (as opposed to Titanum)---...

    Ducted Fans

    I notice that this thread is a bit out dated....... I would like to re-open the conversation if anyone out there is interested in moving forward on the possibilities of a cold jet.... I have a prototype that uses some principles not yet thought about (except for a couple of Experimental...
