Available in PDF, EPUB and Kindle. Book excerpt: In general, with a turbojet engine operating at constant engine speed, bleeding gas from the tail pipe at constant tail-pipe-nozzle area and reduced turbine-inlet temperature caused 2.5 to 4 times as great a loss in thrust as bleeding gas at constant turbine-inlet temperature and reduced tail-pipe-nozzle area.

Download or read book Effect of Heat and Power Extraction on Turbojet Engine Performance III Analytical Determination of Effects of Shaft Power Extraction written by and published by . This book was released on 1950 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The performance of an axial-flow-type turbojet engine operating with shaft-power extraction was analytically determined by matching experimentally determined component characteristics of a typical axial-flow-type engine. Performance is presented in the form of generalized working charts that were used to investigate engine performance with variable and rated tail-pipe-nozzle area operation at constant turbine-inlet temperature, constant engine speed, and constant thrust. A range of altitudes and flight Mach numbers was considered. The maximum power extraction permissible is presented as a function of altitude and thrust.

Download or read book Theoretical Investigation and Application of Transonic Similarity Law for Two Dimensional Flow written by William Perl and published by . This book was released on 1950 with total page 724 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transonic similarity law for two-dimensional flow derived by von Karman was investigated by an iteration procedure similar to that of the Rayleigh-Janzen and Ackeret-Prandtl-Glauert methods. The results, which show that the potential can be expressed as a power series in a single parameter that depends on Mach number, thickness ratio, and ratio of specific heats, are in agreement with those of von Karman. By the iteration procedure, the second approximation for the flow past a Kaplan section was obtained in similarity form. The exact solution by Kaplan for the second approximation was examined and found expressible in the same similarity form. The exact numerical results to three approximations obtained by Kaplan for the Kaplan section and the circular arc have been reduced to transonic similarity form.

Download or read book Electrical Techniques for Compensation of Thermal Time Lag of Thermocouples and Resistance Thermometer Elements written by Charles E. Shepard and published by . This book was released on 1952 with total page 740 pages. Available in PDF, EPUB and Kindle. Book excerpt: Basic electrical networks are described that compensate for the thermal time lag of thermocouple and resistance thermometer elements. For a given set of operating conditions, networks requiring no amplifiers can provide a thirtyfold reduction in effective time lag. This improvement is obtained without attenuation of the voltage signal, but does result in a large reduction in the amount of electric power available because of an increase in the output impedance of the network. Networks used commercially available amplifiers can provide a thousandfold reduction in the effective time lag without attenuation of the alternating voltage signal or or the available electric power, but the improvement is often obtained at the expense of loss of the zero-frequency signal. The completeness of compensation is limited by the extent of off-design operation required.

This book was released on 1951 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical method is presented for obtaining turbulent temperature recovery factors for a thermally insulated surface in supersonic flow. The method is an extension of Squire's analysis for incompressible flow. The boundary layer velocity profile is represented by a power law and a similarity is postulated for squared-velocity the static-temperature-difference profiles.
