RISHigh-Speed Recessed Conical Hybrid Bearings With Additive Manufacturing–Driven Large Gap Clearances for Integrated Bearing–Rotor Architectures of Gas Turbines: Navier–Stokes Analysis and Symbolic–Regression Correlations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Hydrostatic recessed conical bearings operating at high rotational speeds, commonly referred to as hybrid bearings, exhibit several advantages, including structural simplicity, reduced maintenance requirements, ...
Design-for-Additive-Manufacturing Approach for Support-Free Pre-Assembled Micro Gas Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This study presents a preliminary design approach for pre-assembled microgas turbine engines for unmanned aerospace propulsion systems, intended for fabrication via direct metal laser sintering, and demonstrates ...
