Measurements have been made of vortex breakdown position on a series of symmetrical delta wings of 70 degrees sweep angle but differing thickness distribution using a schlieren system to detect the breakdown. The results ...
An attempt has been made to determine whether a large contraction ratio and wire gauze screens in the maximum section would prevent unsteadiness of flow in the return circuit frcm affecting the flow in the working section.
An algebraic solution is given for the problem of ascertaining the probability of finding any number of fatigue cracks in a fleet of aircraft at any specific point in time. By a simple approximation concerning the fatigue ...
