An investigation conducted in the icing research tunnel to determine aerodynamic and icing characteristics of two flush-inlet-type fuel cell vent installations. The vent tubes were mounted in two different locations in the two installations. The vents were aerodynamically investigated to obtain vent-tube static-pressure differentials and pressure surveys as a function of tunnel-air velocity and angle of attack.

Report discussing an aerodynamic control effectiveness study using free-flight, rocket-propelled test vehicles. Information about the effects of wing sweepback, aspect ratio, taper ratio, and section thickness ratio on the rolling effectiveness of full-span, sealed ailerons is provided.

From Summary: "The effects of externally mounted rockets and fuel tanks on the aerodynamic characteristics of an airplane model with a swept-back wing are presented in this report."

The vibration characteristics of a group of axial-flow compressor blades of similar geometry were investigated. Empirical-mode constants were determined for the first three bending and torsional modes. A comparison of experimentally determined frequencies of a second group of blades with frequencies computed using these mode constants showed that the computed values were correct within 10 percent. The approximate limiting ratios of depth to chord and length to chord below which these constants could not be used to compute the natural frequencies were also found experimentally.

Routine inspections of selected Van Stone flanges have been made at all three piles since start-up. In September, 1947, these inspections indicated that corrosion effects were becoming dangerously severe. Some of the flanges appeared to be corroied and pitted to a depth of two-thirds of the original flange thickness. To determine the extent and severity of the corrosion, residual flange thickness measurements were made on the flanges of about 64 scattered tubes. Included were front and rear flanges of tubes from all four orifice zones. Results of the survey indicated the immediate need for an extensive repair program to preclude the possibility of failure of some of the flanges.
