PSP MEASUREMENT OF STATOR VANE SURFACE PRESSURES IN A HIGH SPEED FAN Jan Lepicovsky NYMA, Inc. NASA Lewis Research Center Group, Brook Park, OH Abstract This paper presents measurements of static pressures on the stator vane suction side of a high-speed single stage fan using the technique of pressure sensitive paint (PSP). An experimental investigation of a free power turbine designed for a kW, automotive, gas-turbine engine was made to determine the penalty in performance due to the stator-vane end clearances. Tests were made over a range of mean section stator-vane angles from 26/sup 0/ to 50/sup 0/ with the vane end clearances filled.
A turbine (from the Latin turbo, a vortex, related to the Greek τύρβη, tyrbē, meaning "turbulence") is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful southindiatrails.com work produced by a turbine can be used for generating electrical power when combined with a generator. A turbine is a turbomachine with at least one moving part called a rotor assembly.

A Computational Investigation of Vane Clocking Effects on Embedded Compressor Stage Efficiency. Index Terms - Compressor, NACA, Axial flow, rotor, stator I. INTRODUCTION Axial-flow compressors are used in medium to large thrust gas turbine and jet engines. The compressor rotates at very high speeds, adding energy to the airflow while at the same time compressing it into a.
In recent years, the convective cooling channel has been applied in the compressor vanes to improve the efficiency of Brayton cycle. In order to investigate the influence of cooling on the aerodynamic and heat transfer performance of an intercooled compressor vane, a discontinuous Galerkin (DG) method has been employed in this southindiatrails.com by: 4.
uneventful single engine landing. On initial inspection, maintenance personnel found a single fractured first-stage variable stator vane (VSV) control lever (figure 1). Later internal boroscopic inspection of the engine found significant levels of mechanical damage within the intermediate and high-pressure compressor stages.
Aircraft Mechanic Books; Gas Turbine Engines – Axial-Flow Compressors The main difference between variable inlet guide vane (VIGV) and a variable stator vane (VSV) is their position with regard to the rotor blades.
air enters the front of the engine and is directed into the compressor at the proper angle by the variable inlet guide.
May 07, · The stator vane row behind this rotor is configured as a diffuser to slow the airflow down again by turning it back parallel to the rotor axis.
In so doing, it converts that excess velocity into a rise in static pressure. Modern engines can achieve a pressure rise of up to. Vane clocking is the relative circumferential positioning of consecutive stationary vane rows with the same vane count.
By altering the upstream vane wake's path with respect to the downstream vane, vane clocking changes the blade row interactions and results in a change in steady total pressure loss on the downstream southindiatrails.com: Natalie R.
Smith, Nicole L. Key. What is the key importance of Variable stator vanes in an axial compressor of a gas turbine. can be found in two excellent books: improving the efficiency of a compressor of a gas turbine. Jul 06, · I wanted to know more about stator vanes.
The definition out of the book I'm reading states that "By reducing rotational air movement from the spinning blades, stator vanes sustain linear airflow through the compressor and aid compression." How does the stator vane.
In the case of a piston engine, such as the engine in a car or reciprocating airplane engine, the intake, compression, combustion, and exhaust steps occur in the same place (cylinder head) at different times as the piston goes up and down.
In the turbine engine, however, these same four steps occur at the same time but in different places. A low-pressure compressor exit stator assembly for a gas turbine includes a multiple of vanes mounted between a full hoop outer shroud and an inner shroud.
The outer shroud and inner shroud are mounted to the intermediate case structure. A seal is located between the outer shroud and a bleed duct structure to accommodate thermal growth southindiatrails.com by: AbstractIn order to improve compressor performance using a new design method, which originates from the fins on a humpback whale, experimental tests and numerical simulations were undertaken to investigate the influence of the tubercle leading edge on the aerodynamic performance of a linear compressor cascade with a NACA 65– airfoil.
