Book excerpt: Ramjet and scramjet engines are being developed to provide a more fuel efficient means of propulsion at high Mach numbers. Part of the development of these engines involves test and evaluation of an engine in ground facilities as well as in flight. Ground facilities, like Arnold Engineering Development Complex (AEDC) and those at engine manufacturers like General Electric (GE) and Pratt & Whitney (PW), have decades of experience testing traditional turbine engines and much less experience testing full scale ramjet engines. Testing a supersonic engine in a free-jet mode presents a host of challenges not experienced during traditional direct connect turbine engine tests. Characterizing the performance of an engine in a free-jet test facility is a difficult task due in part to the difficulty in determining how much air the engine is ingesting and the spillage, friction and base drag of the engine installation. As more exotic propulsion systems like DARPA's Falcon Combined Cycle Engine Test (FaCET) article or NASA's X-43 are developed, there is a greater need for effective ground tests to determine engine performance and operability prior to flight testing. This thesis proposes a method for calculating three key performance parameters (airflow, fuel flow, and thrust) and investigates the uncertainty influences for these calculations. A data reduction method was developed for this thesis to calculate the engine airflow, net thrust, and specific impulse (ISP) in a ground test of a generic ramjet engine in a free-jet test facility. It considered typical measurements for an engine test (pressures, temperatures, fuel flow, scale force, and engine and cowl geometry). Once the code was developed, an uncertainty analysis of the calculations was conducted, starting with a simplified analytical assessment. A common industry accepted uncertainty approach was then used in conjunction with the data reduction code to determine the sensitivity or influence coefficients of the independent measurements on the dependent parameters by the dithering method. These influence coefficients were used to ascertain where measurement improvements could be made to affect the greatest reduction in uncertainty of the predicted engine performance.

Book Synopsis Method for Calculation of Ram-jet Performance by : John R. Henry
Download or read book Method for Calculation of Ram-jet Performance written by John R. Henry and published by . This book was released on 1951 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method utilizing precalculated solutions graphically presented for calculating subsonic and supersonic ram-jet thrust coefficients and other important quantities is presented with the associated equations and graphs. Using the assumption of constant values of specific-heat ratio and gas constant equal to those of standard air, the thrust-coefficient calculation has been reduced to a few simple operations. Correction methods are presented to account for variations in specific-heat ratio and gas constant. The correction to the thrust coefficient for a typical set of operating conditions may be of the order of 5 to 10 percent.

Book Synopsis Estimation of Measurement Uncertainty in Engine Tests Based on NATO AGARD Uniform Engine Test Program by : E-33 In Flight Propulsion Measurement Committee
Download or read book Estimation of Measurement Uncertainty in Engine Tests Based on NATO AGARD Uniform Engine Test Program written by E-33 In Flight Propulsion Measurement Committee and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this document is to describe the systematic and random measurement uncertainties which may be expected when testing gas turbine engines in a range of different test facilities. The documentation covers a "traditional" method for estimating pretest uncertainties and a "new" method for computing and comparing posttest uncertainties. To determine these posttest uncertainties, data generated during the AGARD Uniform Engine Test Program (UETP) were analyzed and compared to the pretest estimates.The proposed procedure provides a mechanism for determining the expected accuracy of test results obtained from facilities which were not previously cross calibrated. Furthermore, the method can be used to assist in making cost-effective management decisions on the level of validation/cross calibration necessary when bringing a test facility on line.This document is also intended to act as a guide for improving uncertainty analyses in a broad spectrum of related industries. Measurement uncertainty and measurement system approaches and practices for the UETP are presented in a systematic format. Readers can use these uncertainty approaches and practices for comparison to their own measurement systems.The approach chosen was to analyze three of the UETP test conditions at eight test facilities along with the individual measurement system approaches and practices. The test program provided a wide range of performance measurements and corresponding pretest uncertainty estimates encompassing a variety of test and measurement approaches and practices. Included in the analysis are the basic gas turbine performance measurements of temperature, pressure, airflow, fuel flow, area, speed, thrust, and typical performance parameter functions and associated uncertainty estimates. The overall objectives and approach described in this document were intended to provide guidance and benchmarking. Readers may refer to this approach and practice guidance for application, comparison, or extension to their specific related tasks, using the appropriate technical data, requirements and the most current applicable references. The general approach and guidance are considered stable in regards to the above stated intent.
