This book was released on 1955 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experience accumulated during the past 10 years in measuring turbojet-engine thrust in altitude facilities is summarized herein to indicate the currently best-known techniques applicable for obtaining in-flight thrust measurements. Problems that are encountered in obtaining accurate thrust measurements are illustrated, and the resultant techniques required for measurement of the net thrust of several typical types of turbojet installations are discussed. Techniques for obtaining a performance calibration of the basic engine while it is installed in an airplane are also indicated.

Book Synopsis Experimental Results of an Investigation of Two Methods of Inflight Thrust Measurement Applicable to Afterburning Turbojet Engines with Ejectors by : Harry E. Bloomer
Download or read book Experimental Results of an Investigation of Two Methods of Inflight Thrust Measurement Applicable to Afterburning Turbojet Engines with Ejectors written by Harry E. Bloomer and published by . This book was released on 1958 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was conducted in an altitude test chamber using a turbojet engine equipped with an afterburner and ejector to compare directly two techniques of determining thrust that are both applicable to flight installations. One method is the use of a swinging uncooled rake at the ejector outlet. The other method requires extensive instrumentation to measure the momentum forces of the primary and secondary systems and the force on the internal surface of the ejector nozzle. The two methods are compared on the basis of accuracy, ease of installation calibration required, and so forth. Comparisons are presented so that the reader can be guided to his own choice.

Book Synopsis Full Flight Envelope Direct Thrust Measurement on a Supersonic Aircraft by : Timothy R. Conners
Download or read book Full Flight Envelope Direct Thrust Measurement on a Supersonic Aircraft written by Timothy R. Conners and published by . This book was released on 1998 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Direct thrust measurement using strain gages offers advantages over analytically-based thrust calculation methods. For flight test applications, the direct measurement method typically uses a simpler sensor arrangement and minimal data processing compared to analytical techniques, which normally require costly engine modeling and multisensor arrangements throughout the engine. Conversely, direct thrust measurement has historically produced less than desirable accuracy because of difficulty in mounting and calibrating the strain gages and the inability to account for secondary forces that influence the thrust reading at the engine mounts. Consequently, the strain-gage technique has normally been used for simple engine arrangements and primarily in the subsonic speed range. This paper presents the results of a strain gage-based direct thrust-measurement technique developed by the NASA Dryden Flight Research Center and successfully applied to the full flight envelope of an F-15 aircraft powered by two F100-PW-229 turbofan engines. Measurements have been obtained at quasi-steady-state operating conditions at maximum nonaugmented and maximum augmented power throughout the altitude range of the vehicle and to a maximum speed of Mach 2.0, and are compared against results from two analytically-based thrust calculation methods. The strain-gage installation and calibration processes are also described.

Book Synopsis Uncertainty of In-Flight Thrust Determination by : E-33 In Flight Propulsion Measurement Committee
Download or read book Uncertainty of In-Flight Thrust Determination written by E-33 In Flight Propulsion Measurement Committee and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document defines and illustrates the process for determination of uncertainty of turbofan and turbojet engine in-flight thrust and other measured in-flight performance parameters. The reasons for requiring this information, as specified in the E-33 Charter, are: determination of high confidence aircraft drag; problem rectification if performance is low; interpolation of measured thrust and aircraft drag over a range of flight conditions by validation and development of high confidence analytical methods; establishment of a baseline for future engine modifications.This document describes systematic and random measurement uncertainties and methods for propagating the uncertainties to the more complicated parameter, in-flight thrust. Methods for combining the uncertainties to obtain given confidence levels are also addressed. Although the primary focus of the document is in-flight thrust, the statistical methods described are applicable to any measurement process.The E-33 Committee has endeavoured to gather industry-wide expertise in in-flight measurement and uncertainty analysis to collect and promulgate recommended practices in the subject disciplines. The Committee is organized into subcommittees to address both the analytical and test methodology for determination of in-flight thrust and also the uncertainty of the determination. This document; Uncertainty of In-flight Thrust Determination, AIR1678, addresses the process for determining the uncertainty of in-flight thrust. A companion document, In-Flight Thrust Determination, AIR1703, addresses the basic methodology for determining in-flight thrust.The Committee, after reviewing recommended changes and clarification in definitions and application of statistical uncertainty items, made small revisions to the original document published in 1985. These changes were incorporated into AIR1678 Rev A.This Revision B has the same Scope as preceding versions. The nomenclature and methodology used herein are now consistent with evolving world and national standards promulgated primarily by ISO and ASME. AIR1678B has been reaffirmed to comply with the SAE Five-Year Review policy.
