Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the work was to define, by analysis and experimental evaluation, the design criteria and performance characteristics of the high- pressure-ratio, single-stage centrifugal compressor. The overall performance target was a pressure ratio of 10:1 at an adiabatic efficiency of 80 percent at an airflow of 2 pounds per second. The research was expected to lead to development of advanced technologies applicable to small gas turbine engines. The potential advances identified were: (1) Doubling of current power to weight ratio, (2) Reducing full and part load fuel consumption, and (3) Minimizing cost per horsepower. To illustrate the advances possible, two types of thermodynamic cycles (simple and regenerative) were studied. It was shown that a compressor meeting the above targets would provide an opportunity for reducing specific fuel consumptions to 0.49 pound per horsepower per hour (simple cycle) and 0.38 pound per horsepower per hour (regenerative). This report presents the design and test results of a single-stage, high-pressure-ratio (10:1) centrifugal compressor. Impeller and diffuser modifications are discussed, including diffuser throat boundary-layer bleed.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research program was to define, by analysis and experimental evaluations the design criteria and performance characteristics of a high-pressure-ratio, single-stage centrifugal compressor. The overall performance target was a pressure ratio of 10:1 at an efficiency of 80 percent and at an airflow rate of 2.0 pounds per second. The research was expected to lead to development of advanced technology, applicable to small gas-turbine engines. The research plan was to design 4 impellers and 4 diffusers using the best available knowledge. The components were to be tested and the design methods evaluated. Further tests were to be conducted with modified components to evaluate improvements in the design methods and add to the basic understanding. Each impeller was designed to provide a total-to-total pressure ratio of about 13:1 at a tip speed of 2000 fps, resulting in an absolute Mach number leaving the impeller of about 1.3. The inducers were designed with inlet-relative Mach numbers from 0.95 to 1.23, and the selected impeller diameters were from 6.0 to 8.0 inches. The diffusers were designed to match the impeller discharge Mach number of 1.3. Water-table studies were conducted with diffuser models to develop preliminary evaluations of the flow characteristics. Four diffuser models were selected for test with the same impeller. The diffuser test rig was instrumented with schlieren photography to evaluate the shock system of the diffuser. Diffuser models were designed to vary vaneless-space-diameter ratio, throat Mach number and throat area for investigating flow behavior and variable-airflow-capacity as a means of improving part load fuel consumption.

This book was released on 1969 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of a single stage axial supersonic compressor with a predicted performance of 2.8:1 stage pressure ratio at 82% adiabatic efficiency and 4 lb/sec airflow is discussed. The results of a gas generator performance study to evaluate non-regenerated designs with 16:1 pressure ratio compressors and turbine inlet temperatures between 2500 F and 3000 F are presented and discussed. The design point specific fuel consumption of the engines studied ranged from 0.415 to 0.438 lb/hp/hr. At 50% power this range increased to 0.465 and 0.534 respectively. The engine configuration which indicated the lowest specific fuel consumption has a two spool gas generator and variable stator free power turbine. The preliminary designs of a two stage axial/centrifugal compressor and an advanced gas generator which incorporates this compressor are discussed. The predicted performance of the compressor is 16:1 pressure ratio at an adiabatic efficiency of 77.5% and an airflow of 4 lb/sec. The predicted design point specific fuel consumption and power at a 2500 F turbine inlet temperature are 0.431 lb/hp/hr and 785 hp respectively. The results of a preliminary design study for a variable geometry axial compressor rotor concept are also discussed. This concept offers the potential for improved part speed compressor performance and stage matching. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this program is to facilitate the radial equilibrium analysis of the fluid flow in radial- and mixed-flow impellers for given design conditions. The radial-equilibrium equation is solved at stations normal to the meridional streamlines of an impeller. The total inlet conditions, exit-flow-angle distribution, recovery distribution, and the impeller geometry are inputs to the program. The design results printed out consist of temperatures, pressures, velocities, and angles determined at equilibrium streamlines for the inlet and downstream normal stations. The equilibrium results are used to compute blade surface velocities, which are also program outputs.
