General Science / Aerospace: Magnetic Levitating Rim Driven Ducted Fan - Possible or Not?
« on: 18/12/2023 12:45:09 »
Hello Forum Members,
I am currently occupied in exploring innovative solutions for aerospace propulsion systems, with a specific focus on enhancing efficiency and reducing noise. I am reaching out to seek your expertise in evaluating the feasibility of a concept I've been pondering about.
In my quest to optimize aerospace propulsion, I am contemplating repositioning the electric drive motor from the center to the rim of the system, into the duct itself. This shift presents both advantages and challenges. Notably, it eliminates the tip gap between the rotor and stator, addressing significant pressure losses observed in current aerospropulsion systems. Additionally, this configuration enables the system to intake and expel air more efficiently, enhancing overall aerodynamic performance.
While I believe the rim-driven aspect is feasible, my next consideration involves the removal of classical roller ball bearings to reduce friction and associated inefficiencies. The proposed solution is a magnetic levitating setup. Imagine a high-speed maglev train executing an infinite loop. Makes sense?
To achieve a completely contactless setup and minimize friction to the bare minimum dictated by aerodynamics, the levitation unit must exert a force capable of not only lifting the rotor but also supporting the entire weight of the aircraft, including loads from aerodynamics and general aircraft control.
As someone more inclined towards creativity than mathematics, I am seeking assistance in performing basic calculations to determine the strength required for electromagnets to make this concept a reality.
Your insights and expertise would be immensely valuable in assessing the viability of this propulsion system modification. I appreciate any input or calculations you can provide on the strength of electromagnets needed for this ambitious concept.
This topic is something I am greatly passionate about. I am really looking forward to start a conversation and receive your input.
Thank you for your time and consideration.
