Wall interference in a two-dimensional-flow wind tunnel, with consideration of the effect of compressibility (open access)

Wall interference in a two-dimensional-flow wind tunnel, with consideration of the effect of compressibility

From Summary: "Theoretical tunnel-wall corrections are derived for an airfoil of finite thickness and camber in a two-dimensional-flow wind tunnel. The theory takes account of the effects of the wake of the airfoil and of the compressibility of the fluid, and is based upon the assumption that the chord of the airfoil is small in comparison with the height of the tunnel. Consideration is given to the phenomenon of choking at high speeds and its relation to the tunnel-wall corrections. The theoretical results are compared with the small amount of low-speed experimental data available and the agreement is seen to be satisfactory, even for relatively large values of the chord-height ratio."

The Knock-Limited Performance of Several Fuels Blended With S-2 Reference Fuel (open access)

The Knock-Limited Performance of Several Fuels Blended With S-2 Reference Fuel

Report discussing the results of testing conducted to determine the knock-limited performance of fuel blends containing 80 percent of S-2 reference fuel and 20 percent of several exploratory fuels. Butyl acetate, sec-butyl acetate, isopropyl acetate, sec-butyl alcohol, tert-butyl alcohol, isopropyl alcohol, cyclohexanol, methylcyclohexanol, isobutylcarbinol, sec-butylcarbinol, triethyl borate, and dimethylfuran were examined.

Trends in Surface-Ignition Temperatures (open access)

Trends in Surface-Ignition Temperatures

Report discusses the variation of surface-ignition temperature with charge density, fuel-air ratio, and surface-ignition advance. Tests on several fuels were conducted on a supercharged CFR engine to determine surface-ignition temperature as a function of the three variables. It was concluded that surface-ignition temperature is not a satisfactory criterion for differentiating between preignition characteristics of different fuels.

The Effect of Compression Ratio on Knock Limits of High-Performance Fuels in a CFR Engine 1: Blends of Triptane and 28-R Fuel (open access)

The Effect of Compression Ratio on Knock Limits of High-Performance Fuels in a CFR Engine 1: Blends of Triptane and 28-R Fuel

Report discussing the knock-limited performance of blends of triptane and 28-R fuel in an F-4 engine at three sets of conditions and three compression ratios. The knock limits of the triptane blends were more sensitive to compression ratio than the 28-R fuel, and the sensitivities of the blends increased as the severity of other engine conditions increased.

Knock-Limited Performance of Blends of AN-F-28 Fuel Containing 2 Percent Aromatic Amines 4

Report discussing tests on the effect of 2-percent additions of 13 aromatic amines on the knock-limited performance of 28-R fuel in a CFR engine. The amines tested gave good rich mixture response at standard F-4 operating conditions, but were sensitive to engine severity at lean fuel-air ratios.
