Magnetic Suspension Conical Compressor (MSCC)

Summary: A high-efficiency, oil-free compressor architecture using a magnetically suspended conical rotor with internal groove dynamics for gas compression, cooling, and adiabatic expansion — ideal for aerospace propulsion, closed-loop Brayton cycles, and compact cryogenic systems.

🔌 Motivation

Conventional turbomachinery suffers from mechanical friction, lubricant contamination, and scale inefficiencies in small formats. This project proposes a frictionless, high-speed compressor using magnetic suspension and helical groove aerodynamics to enable efficient microscale or mesoscale thermodynamic systems.

🔹 Architecture Overview

  • Rotor: Magnetically suspended, gas-lubricated conical rotor

  • Housing: Grooved cone matching rotor helix to guide laminar flow

  • Clearances: Micron-scale tolerances, no mechanical contact

  • Thermal Extraction: Outer housing grooves act as heat sinks

  • Expansion Stage: Tight nozzle outlet enables adiabatic expansion

  • Use Case: Can connect to recuperators, turbines, or fuel injectors downstream

🔢 Key Features

  • No mechanical contact: reduces wear, friction, and heat loss

  • Oil-free: suitable for oxygen or high-purity systems

  • Passive magnetic bearing design: simple and low power

  • Laminar compression: reduces turbulence and noise

  • Adiabatic expansion nozzle: boosts energy efficiency

🌐 Applications

  • Aerospace cooling loops (e.g., LPT turbine intercooling)

  • Cryogenic refrigeration and liquefaction systems

  • Waste heat recovery in closed Brayton cycles

  • Fuel cell air compressors

  • Portable heat pumps / microturbines
