Download or read book Gas Turbine Engine Inlet Flow Distortion Guidelines written by S-16 Turbine Engine Inlet Flow Distortion Committee and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The turbine-engine inlet flow distortion methodology addressed in this document applies only to the effects of inlet total-pressure distortion. Practices employed to quantify these effects continue to develop and, therefore, periodic updates are anticipated. The effects of other forms of distortion on flow stability and performance, and of any distortion on aeroelastic stability are not addressed.The guidelines can be used as necessary to create a development method to minimize the risk of inlet/engine compatibility problems. The degree to which guidelines for descriptor use, assessment techniques, and testing outlined in this document are applied to a specific program should be consistent with the expected severity of the compatibility problem. This document provides definitions of stability margin and total-pressure distortion descriptors for gas turbine engines. In addition, guidelines for stability assessments, testing, instrumentation, data acquisition, and data processing are addressed.This document contains information that is fundamental to the discipline of inlet-engine compatibility and is expected to remain stable for the foreseeable future.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The turbine-engine-inlet flow distortion descriptors summarized in this document apply to the effects of inlet total-pressure, planar-wave, and total-temperature distortions. Guidelines on stability margin, destabilizing influences, types and purposes of inlet data, AIP definition, and data acquisition and handling are summarized from AIR5866, AIR5867, ARP1420, and AIR1419. The degree to which these recommendations are applied to a specific program should be consistent with the complexity of the inlet/engine integration. Total-pressure distortion is often the predominant destabilizing element that is encountered and is often the only type of distortion to be considered, i.e, not all types of distortion need to be considered for all vehicles. The SAE S-16 Turbine Engine Inlet Flow Distortion Committee has developed an Aerospace Recommended Practice (ARP) and Aerospace Information Reports (AIR) describing measurement stations and techniques, and descriptors for different types of inlet total-pressure, planar-wave, and total-temperature distortion. There has been broad acceptance of these descriptors by the industry. Although a treatment for swirl distortion has been proposed, no methodology for swirl distortion has gained wide acceptance. When an accepted methodology exists for swirl distortion, this document will be updated to include it. This document provides a single source that contains the recommended measurement stations and techniques, and descriptors for total-pressure, planar-wave, and total-temperature inlet distortion.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report revises ARD50015 document to the AIR format. This report, as was the original, is intended to complement ARP1420C and AIR1419C documents issued by the SAE S-16 Committee on spatial total-pressure distortion. These previous documents addressed only total-pressure distortion and excluded total temperature distortion.The subject of inlet total temperature distortion is addressed in this report with some background and identification of the problem area. The status of past efforts is reviewed, and an attempt is made to define where we are today. Deficiencies, voids, and limitations in knowledge and test techniques for total temperature distortion are identified. Due to the needs of the industry, this document has been upgraded to an AIR (Aerospace Information Report) from an ARD (Aerospace Research Document) status and was formerly catalogued as ARD50015. Most of the report is unchanged since the material is as useful now as it was when first published in 1991. Considerable total temperature distortion research has been accomplished since the publication of the original document, but these data are not available for public release. Thus, complete revision of this document is not presently warranted. A few paragraphs have been updated to reflect knowledge gained on recent aircraft programs. Other changes reflect consistency with more recently adopted definitions, and minor editorial and typographical corrections. Attempts were also made to update quality and timeliness of the original figures and tables. However, because it was not possible to retrieve some of the original material, the existing relevant figures and tables were kept, resulting in a varying appearance throughout this revision.As applications for turbine engines have become more sophisticated and the operating conditions more severe, the SAE S-16 Turbine Engine Inlet Flow Distortion Committee has recognized the need for guidelines and procedures that would address inlet flow total-temperature distortion in a manner similar to that accomplished for inlet flow total-pressure distortion, which resulted in the SAE documents ARP1420C and AIR1419C. This document brings together information and ideas which are required to address total temperature distortion problems.This document has been cleared for public release.The SAE S-16 Committee welcomes input from both industry and government organizations relative to the contents of this report and information on current and future programs in this important technical area as the committee attempts to define standard guidelines.

Download or read book Inlet Engine Compatibility From Model to Full Scale Development written by S-16 Turbine Engine Inlet Flow Distortion Committee and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document reviews the state of the art for data scaling issues associated with air induction system development for turbine-engine-powered aircraft. In particular, the document addresses issues with obtaining high quality aerodynamic data when testing inlets. These data are used in performance and inlet-engine compatibility analyses. Examples of such data are: inlet recovery, inlet turbulence, and steady-state and dynamic total-pressure inlet distortion indices. Achieving full-scale inlet/engine compatibility requires a deep understanding of three areas: 1) geometric scaling fidelity (referred to here as just "scaling"), 2) impact of Reynolds number, and 3) ground and flight-test techniques (including relevant environment simulation, data acquisition, and data reduction practices). The Model-to-Full Scale Subcommittee of the S-16 Turbine Engine Inlet Flow Distortion Committee has examined archives and has obtained recollections of experts regarding air induction system development experience to produce this document. The intent of this document is to capture the experience and lessons learned since approximately 1967 necessary to ensure that model-scale inlet total-pressure recovery and distortion data faithfully represent the corresponding full-scale inlet recovery and distortion characteristics.This document contains information that is fundamental to the discipline of inlet-engine compatibility and is expected to remain stable for the foreseeable future.

This book was released on 1976 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: A performance evaluation of an airjet distortion generator system used to produce steady-state, total-pressure distortion at the inlet to a turbine engine was conducted. The capability of the system to duplicate screen-generated, parametric distortion patterns (180 deg, one per revolution; tip radial; hub radial) and to maintain a constant composite distortion pattern over a range of airflows is presented. A comparison of the effect of inlet distortion produced by screens to that produced by the airjet distortion generator system on the stability characteristics of a present-day turbofan engine is described.

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.

This book was released on 2018-08-14 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Static pressure and total pressure distributions were measured in the inlet duct upstream of the engine inlet and within the fan and compressor of a YTF34 turbofan engine. In addition, the free stream flow angle was measured between the distortion generator and the engine inlet. Distortions were generated using three screen configurations with extents of 90 deg or 180 deg. The screens were mounted on a rotatable screen assembly. Reynolds number index upstream of the distortion device was maintained at 0.5 or 0.2, and engine fan speed corrected to station 2 temperature was maintained at 80 or 90 percent of rated condition (7005 rpm). Flow angle was nearly constant near the distortion device and increased as flow approached the engine inlet. The largest flow angle occurred in the hub region of the engine inlet. Static pressure distortion along the inlet duct increased exponentially as the flow approached the engine. Both static pressure and total pressure distortions were attenuated between engine inlet and compressor exit. Soeder, R. H. and Bobula, G. A.
