A model would be a good (and probably more accesible (unless you live close to and have access to a good engineering school) than computer simulation) method to test this ideation. I wish you the best of luck, as I am a novice inventor myself and think it is awesome that you put this out on the web for people to comment and debunk. Most all the best inventions have come from someones garage!
Thank you for your thoughts ! I think that one of the things that makes it necessary for impellers/fans/compressors to have thin blades is that if they are too thick then the friction against the surface would cause a larger boundary layer to move in a circular motion thus effected by centrifugal force . The ring is an option but it need not be heavy imo especially if it made of carbon fiber and i think the main force acting upon the ring would be centrifugal force keeping it nice and circular
But this is one idea for trying to mitigate the effects of centrifugal force imparted to the air caused by blades of greater chord . The simulations sound like a good idea . Maybe I will just build a model of it and test it out and see though .
I have a prediction for you : It will not be debunked . In fact , as the technology of blade construction advances, this shape will become commonplace in turbofans . As well I wish you the best of luck with your inventions !
Another thing to consider is where you want the air to go. The design that you criticized will probably push the air outward, and the one you gave will push the air inward. If you want more air to bypass the turbojet part of the turbofan engine, you probably want to push the air outwards. If you don't have enough air in the turbojet part, then we should use your design.
Thank you for your input! The intent of the shape would be to counteract the effect of centrifugal force on the air and convert it into linear movement . Looking back , I guess i might have made this vid more concise and and explain better. Experimentation will yield the answers.
I am definitely not an expert in the field, but I would think your design would cause cavitation and/or extreme pressure changes (and in turn temp changes) due the anticipated air acceleration path. Your suggested ring on the outside causes a lot of additional weight, which means a lot more energy into rotating the system. Just something to think about. If you a serious about this, try designing it in CAD and running it through some fluid model simulations.
In theory, wouldn't this design pull air towards the center, working against the centrifugal force? so instead of mitigating the effects of this radial force, your actually doing the exact opposite.. This may in turn increase the torque necessary to keep the fan at a constant speed. i am an engineer at Purdue U and can assume that there are a lot of highly intellectual people working at rolls royce running optimization simulations constantly and id be surprised if this wasn't already attempted.
