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.

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 1975 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: An in-flight thrust measurement and display system (TMS) for an afterburning turbojet engine with a continuously variable exhaust nozzle has been developed by Computing Devices Company. A special-purpose digital computer calculates engine gross thrust using aerothermodynamic equations requiring ambient static pressure, and three engine tailpipe pressures as inputs. A reference gross thrust is also calculated for a nominal or average engine operating at military power under the prevailing ambient conditions. The display system provides updates of gross thrust and the percentage of the reference gross thrust at the rate of two per second. Flight-rated digital data recording equipment is interfaced with the system to provide a consistency check of the flight data. (Author).
