Book Effect of Steady state Pressure Distortion on Inlet Flow to a High bypass ratio Turbofan Engine

Download or read book Effect of Steady state Pressure Distortion on Inlet Flow to a High bypass ratio Turbofan Engine written by Ronald H. Soeder and published by . This book was released on 1982 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments were conducted to determine the effects of steady-state circumferential-pressure distortion on inlet flow and internal engine performance of a high-bypass-ratio turbofan engine. To measure these effects, flow-angle, static-pressure, and total-pressure instrumentation was placed between the rotatable distortion-generator assembly and the engine inlet. In addition, both static-pressure and total-pressure were recorded at the fan exit and compressor inlet and exit. Three circumferential screens were separately mounted on the rotatable assembly. For all configurations data were recorded at each of twelve 30 deg increments of assembly rotation. Experiments were conducted with fan speeds (corrected to station 2 temperature) of 80 or 90 percent of rated condition (7005 rpm) and Reynolds number indices of 0.2 or 0.5. Yaw angle increased between the distortion-generating assembly and the engine inlet. A change in Reynolds number index (RNI) has only a slight effect and a change in speed had no effect on yaw angle distribution. The flow angle was largest in the hub region of the engine inlet.

Book Effects of Inlet flow air Distortion on Steady state Altitude Performance of an Axial flow Turbojet Engine

Download or read book Effects of Inlet flow air Distortion on Steady state Altitude Performance of an Axial flow Turbojet Engine written by E. William Conrad and published by . This book was released on 1955 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of inlet-air-flow distortion on the steady-state performance of a current axial-flow turbojet engine were studied in an NACA altitude test chamber at altitudes from 15,000 to 50,000 feet at a simulated flight Mach number of 0.8. Radial distortions of various shapes up to 22 percent of the average engine-inlet total pressure and circumferential distortions up to 26 percent were imposed. Data were obtained for operation with the variable-position inlet guide vanes in both the open and closed positions with rated exhaust-nozzle area and for exhaust nozzle open with the guide vanes in the open position.

Book Effects of Steady State Pressure Distortion on the Stall Margin of a J85 21 Turbojet Engine

Download or read book Effects of Steady State Pressure Distortion on the Stall Margin of a J85 21 Turbojet Engine written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-26 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of the inlet pressure distortions, induced by five screen patterns, on the performance of a J85-21 turbojet engine was conducted at the NASA Lewis Research Center. Testing was in support of the HiMAT RPRV program at Dryden Flight Research Center. Distortion patterns were chosen based on anticipated application of test results of the HiMAT installation. Tests were conducted at a simulated Mach number and altitude condition of 0.9 and 10 973 meters. Results are presented in terms of distortion levels and standard compressor performance parameters.

Book Effect of Heat and Power Extraction on Turbojet engine Performance

Download or read book Effect of Heat and Power Extraction on Turbojet engine Performance written by Stanley L. Koutz and published by . This book was released on 1951 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: In general, with a turbojet engine operating at constant engine speed, bleeding gas from the tail pipe at constant tail-pipe-nozzle area and reduced turbine-inlet temperature caused 2.5 to 4 times as great a loss in thrust as bleeding gas at constant turbine-inlet temperature and reduced tail-pipe-nozzle area.

Book Effect of Steady State Inlet Temperature Distortion on the Engine Compressor Flow

Download or read book Effect of Steady State Inlet Temperature Distortion on the Engine Compressor Flow written by W. Koschel and published by . This book was released on 1987 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: A prediction model for the effects of a steady state temperature distortion on the overall performance of a multistage engine compressor is presented. In contrast to the well-known parallel compressor model, this method takes into account the circumferential interaction of the distorted and undistorted compressor flow. An extensive experimental program has been carried out on a single-spool jet engine with steady-state inlet temperature and pressure distortion tests. The experimental set-up is briefly described. Detailed results of the flow measurements obtained at the compressor inlet and exit and at the compressor interstage positions are presented and discussed. The experimental results support the validity of the prediction model developed within this project.

Book Generalization of Turbojet engine Performance in Terms of Pumping Characteristics

Download or read book Generalization of Turbojet engine Performance in Terms of Pumping Characteristics written by Newell D. Sanders and published by . This book was released on 1949 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Characteristics of a basic turbojet engine consisting of compressor, combustor, and turbine can be presented in terms of pumping characteristics; that is, corrected air flow, ratio of engine-outlet to -inlet total pressure, ratio of engine-outlet to -inlet total temperature, Reynolds number index, corrected engine speed, and corrected fuel-air ratio. Such a presentation describes the engine independently of the characteristics of other elements of the propulsion system. This method of presentation also permits rapid estimation of performance of complex propulsion systems involving the basic tubojet engine.

Book The Effect of Increase in Combustion air Inlet Temperature from 80 to 130 Degrees F on the Sea level Performance of a 22 inch diameter Pulse jet Engine

Download or read book The Effect of Increase in Combustion air Inlet Temperature from 80 to 130 Degrees F on the Sea level Performance of a 22 inch diameter Pulse jet Engine written by Michael F. Valerino and published by . This book was released on 1946 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data from a sea-level investigation of a 22-inch-diameter pulse-jet engine installed on a thrust stand were analyzed to determine the effect on the engine performance of a change in combustion-air temperature from approximately 80 to 130 degrees F. The tests at both combustion-air temperatures covered a range of simulated ram pressures from 19 to 58 inches of water for the fuel-flow range of resonant operation.
