RISThree Dimensional Tailored Vibration Response and Flutter Control of High Bypass Shroudless Aeroengine Fans
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new reducedorder design synthesis technology has been developed for vibration response and flutter control of coldstream, highbypass ratio, shroudless, aeroengine fans. To simplify the design synthesis (optimization) of ...
A Reduced Order Meshless Energy Model for the Vibrations of Mistuned Bladed Disks—Part II: Finite Element Benchmark Comparisons
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper draws upon the theoretical basis and applicability of the threedimensional (3D) reducedorder spectralbased “meshless†energy technology presented in a companion paper (McGee et al., 2013, “A ReducedOrder ...
A Reduced Order Meshless Energy Model for the Vibrations of Mistuned Bladed Disks—Part I: Theoretical Basis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a reduced order model for the vibrations of bladed disk assemblies was achieved. The system studied was a 3D annulus of shroudless, “customtailored,†mistuned blades attached to a flexible disk. Specifically, ...
Aeromechanical Control of High Speed Axial Compressor Stall and Engine Performance—Part II: Assessments of Methodology
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A theoretical assessment was made explaining how aeromechanical feedback control can be implemented to stabilize rotating stall inception in highspeed axial compression systems. Ten aeromechanical control strategies were ...
Aeromechanical Control of High Speed Axial Compressor Stall and Engine Performance— Part I: Control Theoretic Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: General methodologies are proposed in this twopart paper that further phenomenological understanding of compressible stall inception and aeromechanical control of highspeed axial compressors and engine performance. Developed ...
