Blade to blade vibration damper
The Journal of the Acoustical Society of America, 1983L'appareil ci-decrit permet l'amortissement effectif de l'energie vibratoire des aubes. The apparatus described above enables the effective damping of the vibratory energy of the blades. Les concepts concernent essentiellement l'amortissement dit aube-aube en comparaison a l'amortissement aube-sol.

Blade to blade vibration damper
The Journal of the Acoustical Society of America, 1985Apparatus for dampening rotor blade vibratory energy in a rotary machine is disclosed. Concepts employing blade to blade damping are discussed. In one detailed form, a damper (52) is disposed to seat against the undersides of adjacent blade platform sections (20) and a seal (42) is spaced sufficiently close to the damper so as to be deflected ...

Fan Blade Flutter: Single Blade Instability or Blade to Blade Coupling?
Volume 1: Aircraft Engine; Marine; Turbomachinery; Microturbines and Small Turbomachinery, 1985Different types of fan blade flutter occur at the various compressor flow regimes. Sub/transonic stall flutter and two forms of supersonic started flow flutter have been studied in a straight cascade wind tunnel. Results show clearly that these three common forms of flutter can exist as single-degree-of-freedom (single-blade instabilities).

Stability analysis of the n-bladed system with blade-to-blade interaction
Proceedings of Global Power & Propulsion Society, 2023This paper presents a new approach based on simplified dynamic modelling of the blade and blade-to-blade interaction, which generally occurs due to flow structures with large extent such as tip clearance vortex. The model considers the blade-to-blade interaction as the primary cause of the local instability.

Individual blade control of hinged blades using smart structures
Smart Materials and Structures, 1994The feasibility of employing piezoceramic smart materials in active control of the higher harmonic vibration of hinged helicopter blades is investigated. The individual-blade-control concept is adopted to build feedback controllers that employ collocated smart sensors and actuators and are optimized to achieve damping augmentation for blade modes that ...

Guarded Microvitreoretinal Blade
Archives of Ophthalmology, 1996During vitreoretinal surgery, the microvitreoretinal blade may be misdirected and injure operating room personnel. A sheated, retractable blade has been developed to reduce the likelihood of such injuries. In the blade's retracted position, a safety feature prevents inadvertent exposure of the sharp blade.
