P. NarasimhamurthyBISPLINGHOFF has given a comparative graph showing the relative importance of the parameters of design at various Mach numbers. At Mach numbers above five, i.e. in the range of…
Measurement of Adhesive Moduli: The Use of Ultrasonics to Measure the Dynamic Modulus of Metal‐to‐Metal Adhesive Joints
P.F. Tapp, A. Broodo, C.E. Horn, S.V. CastnerMANY efforts have been made to evaluate adhesion by relating adhesion to measured forces. Many of these are comparative and do not actually measure adhesion alone, but depend upon…
The Annular Aerofoil with Central Body and Propeller: An Approximate Method for the Estimation of the Velocity and Pressure Distribution over the Surface of a Circular Annular Aerofoil with Central Body and Propeller
Svetopolk PivkoCONSIDER an isolated circular fairing whose cross‐sections along in the flow direction are of aerofoil shape, inclined at small angle of attack a, FIG. 1. By applying the general…
