Rotor dynamics of a sliding vane turbine
Mechanism and Machine Theory, 1976Abstract A general mechanical design and performance analysis is presented for a sliding vane turbine. The analysis is general in the sense that it is valid for any stator profile and that there is no restriction on the turbine use. This analysis includes a dynamic force analysis on the vane, rotor dynamics, and vane kinematics.

Nanobrazing for Turbine Blade and Vane Repair
AM&P Technical Articles, 2017Abstract Nanobrazing is an innovative brazing technique that uses nanomaterials as the filler materials. Incorporating nanobrazing into conventional technologies such as vacuum and laser brazing creates a new frontier for repairing turbine blades and vanes.

Aerodynamic investigation of turbine cooled vane block
Thermal Engineering, 2015The vane block (VB) has been investigated and it gives several important results related to test methods and calculation procedures. The vane block is characterized by a developed film and convective cooling system. Blowing tests demonstrate that there is a weak correlation between cooling type and energy loss.

Abstract A turbine vane made of cast cobalt-base alloy AMS 5382 (Stellite 31; composition: Co-25.5Cr-10.5Ni-7.5W) was returned from service after an undetermined number of service hours because of crack indications on the airfoil sections. This alloy is cast by the precision investment method.

Cooling system optimisation of turbine guide vane
Applied Thermal Engineering, 2009This paper discuses the problem of cooling system optimisation within a gas turbine vane. The analysis involves the optimisation of size and location of internal cooling passages within the vane. Cooling is provided with ten circular passages and heat is transported only convectively. The task is approached in 3D configuration. Each passage is fed with

Modeling of Combustor and Turbine Vane Interaction
Volume 2C: Turbomachinery, 2019Abstract Modern aero-engines are characterized by compact components (fan, compressor, combustor, and turbine). Such proximity creates a complex interaction between the components and poses a modeling challenge due to the difficulties in identifying a clear interface between components since they are usually modeled separately.

Metal-Reinforced Ceramic Composites for Turbine Vanes
ASME 1972 International Gas Turbine and Fluids Engineering Conference and Products Show, 1972Experiments have been performed which indicate the potential of metal-fiber reinforced-ceramic matrix composites for use as a high temperature structural matrix. The results of this work reveal that metal-fiber reinforced ceramics obey compostie theory, and that after cracks occur in the matrix, a pseudo-ductility can be introduced into the composite ...

Air Cooling of Turbine Blades and Vanes
Aircraft Engineering and Aerospace Technology, 1967THE demand of the aircraft designer has been, and presumably always will be, for his engines to operate better in three basic respects. To give more thrust, to have less weight, and to require less fuel.

Thermo-Structural Analysis of Ceramic Vanes for Gas Turbines
Advances in Science and Technology, 2006Advanced structural ceramics such as Hot Pressed Silicon Nitride (HPSN) and Reaction Bonded Silicon Carbide (RBSC), thanks to their low density (3.1 ÷ 3.4 gr/cm3) and to their thermostructural properties, are interesting candidates for aerospace applications.
