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.

This book was released on 1966 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laboratory tests indicated that: (1) the gross thrust value computed theoretically from the measured pressures were within plus or minus 2.0% of the thrust stand measured gross thrust, (2) the thrustmeter gross thrust values were within plus or minus 3.0% of the thrust stand measured values, (3) the net thrust values computed theoretically from the measured pressures were within plus or minus 3.9% of the thrust stand measured net thrust, and (4) the thrustmeter net thrust values were within plus or minus 4.2% of the thrust stand measured net thrust. The gross thrust computer module malfunctioned for a series of tests at a simulated altitude condition of 40,000 feet and Mach 1.2. Flight test results indicated that the system functioned properly aboard the aircraft and was responsive to small changes in engine power setting. The thrustmeter gross thrust and net thrust values agreed with the computed gross and net thrust of the engine within plus or minus 2.2% and plus or minus 2.8% respectively. In measuring net thrust during the flight tests, some difficulty was encountered in obtaining consistent static pressure readings at the compressor inlet station thus causing errors in the computation of ram drag.

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.
