Data for Design of Entrance Vanes from Two-dimensional Tests of Airfoils in Cascade by Charles M. Zimmey,Viola M. Lappi Pdf

Data obtained from tests of five NACA blower-blade sections and four experimentally driven sections are presented in the form of entrance vane design charts for axial-flow compressors or turbines. These charts give blade section and angle of attack for any turning angle. Blades thus obtained operate with peak-free pressure distributions. These series of blower-blade sections, with relatively high critical speeds, will efficiently turn air flowing in an axial direction from 0 to 80 degrees.

Two-dimensional Compressible Flow in Centrifugal Compressors with Straight Blades by John D. Stanitz,Gaylord O. Ellis Pdf

Six numerical examples are presented for steady, two-dimensional, compressible, nonviscous flow in centrifugal compressors with straight blades. A seventh example is presented for incompressible flow. The solutions also applye to radial-flow turbines with rotation and flow direction reversed. The effects of variations in following parameters were investigated: (1) flow rate, (2) impeller-tip speed, (3) variation of passage height with radius, and (4) number of blades. The numerical results are presented in plots of the streamlines, constant Mach number lines, and constant pressure-ratio lines. Correlation equations are developed whereby the flow conditions in any impeller with straight blades can be determined for all operating conditions.

Methods for Obtaining Desired Helicopter Stability Characteristics and Procedures for Stability Predictions by F. B. Gustafson,Robert J. Tapscott Pdf

Part 1 of this report presents a brief review of methods available to the helicopter designer for obtaining desired stability characteristics by modifications to the airframe design. The discussion is based on modifications made during the establishment of flying-qualities criteria and includes sample results of theoretical studies of additional methods. The conclusion is reached that it is now feasible to utilize combinations of methods whereby stability-parameter values are realized which in turn provide the desired stability characteristics. Part 2 reviews some of the methods of predicting rotor stability derivatives. The procedures by which these rotor derivatives are employed to estimate helicopter stability characteristics have been summarized.

Attainable Circulation of Airfoils in Cascade by Arthur W. Goldstein,Artur Mager Pdf

From consideration of available information on boundary-layer behaviour, a relation among profile thickness, maximum surface velocity, Reynolds number, velocity diagram, and solidity is established for a cascade of airfoils immersed in a two-dimensional incompressible fluid flow. Several cascades are computed to show the effect of various cascade design parameters on minimum required cascade solidity.

Method for Determining Optimum Division of Power Between Jet and Propeller for Maximum Thrust Power of a Turbine-propeller Engine by Arthur M. Trout,Eldon W. Hall Pdf

Charts are presented by means of which the jet pressure ratio that give optimum division of power between propeller and jet for maximum total thrust power may be determined for any turbine-propeller engine with or without intercooling, reheat, regeneration, or any combination of these modifications.
