Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation of stall propagation in a stationary circular cascade in which high-speed schlieren and interferometer photography is used is described. This investigation suggests an analytical approach to the study of stall propagation which is valid only for an isolated blade row in an infinite flow field but which is not restricted to small unsteady perturbations or to an assumed simplified cascade geometry. Conditions necessary for the existence of the assumed type of stall cells are described and equations are derived for the velocity of stall-cell propagation.

Book excerpt: An experimental investigation of stall propagation in a stationary circular cascade in which high-speed schlieren and interferometer photography is used is described. This investigation suggests an analytical approach to the study of stall propagation which is valid only for an isolated blade row in an infinite flow field but which is not restricted to small unsteady perturbations or to an assumed simplified cascade geometry. Conditions necessary for the existence of the assumed type of stall cells are described and equations are derived for the velocity of stall-cell propagation. The propagation velocities predicted for the theoretical potential-flow model correlate with all the experimental values measured in an isolated rotor within 15 percent. Analysis of the flow model leads to the prediction of a tendency for the assumed type of stall cell to split with increasing incidence of the mean flow through the blade row. This tendency appears to correspond with the experimental observation of a trend for increasing numbers of cells in the rotor.

This book was released on 2015-12-08 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume XI of the High Speed Aerodynamics and Jet Propulsion series. Edited by W.R. Hawthorne and W.T. Olson. This is a comprehensive presentation of basic problems involved in the design of aircraft gas turbines, including sections covering requirements and processes, experimental techniques, fuel injection, flame stabilization, mixing processes, fuels, combustion chamber development, materials for gas turbine applications, turbine blade vibration, and performance. Originally published in 1960. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Download or read book Effect of Pneumatic De icers and Ice Formations on Aerodynamic Characteristics of an Airfoil written by Dean T. Bowden and published by . This book was released on 1956 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements of lift, drag, and pitching moment of an NACA 0011 airfoil were made in icing using two types of pneumatic de-icers, one having spanwise inflatable tubes and the other having chordwise tubes. Ice remaining after inflation of the spanwise-tube de-icer increased airfoil section drag 7 to 37 percent for 0 to 4.6 degrees angle of attack over the ranges of airspeed, total air temperature, liquid-water content, and cycle times covered. This drag increase became constant after a few de-icing cycles. Drag increases due to ice remaining on the chordwise-tube de-icer were similar to those for the spanwise-tube de-icer. Minimum airfoil drag in icing (averaged over a de-icing cycle) was usually obtained with a short (about i min) de-icing cycle.
