Effect of high air velocities on the distribution and penetration of a fuel spray
Author(s): Rothrock, A M
Abstract: By means of the NACA Spray Photography Equipment high speed moving pictures were taken of the formation and development of fuel sprays from an automatic injection valve. The sprays were injected normal to and counter to air ...

Effect of nose shape on the characteristics of symmetrical airfoils
Author(s): Pinkerton, Robert M
Abstract: Tests of nine symmetrical airfoils, having different leading-edge radii, were made in the variable density wind tunnel. Three symmetrical NACA airfoils having maximum thickness-to-chord ratio of 0.06, 0.012, and 0.018 were ...

Combined pitching and yawing motion of airplanes
Author(s): Baranoff, A V; Hopf, L
Abstract: This report treats the following problems: The beginning of the investigated motions is always a setting of the lateral controls, i.e., the rudder or the ailerons. Now, the first interesting question is how the motion would ...
