Investigation of Aerodynamic and Icing Characteristics of a Flush Alternate Inlet Induction System Air Scoop

Description: "An investigation has been made in the NACA Lewis icing research tunnel to determine the aerodynamic and icing characteristics of a full-scale induction-system air-scoop assembly incorporating a flush alternate inlet. The flush inlet was located immediately downstream of the offset ram inlet and included a 180 deg reversal and a 90 deg elbow in the ducting between inlet and carburetor top deck. The model also had a preheat-air inlet" (p. 1).

Buffeting of a vertical tail on an inclined body at supersonic Mach numbers

Description: Report presenting time histories of rolling and yawing moments on inclined bodies of revolution with vertical-tail surfaces at several Mach numbers and Reynolds numbers. Three ogival-nose bodies with three overall fineness ratios and a conical-nosed body with a fineness ratio of 12.0 were tested. Results regarding the visual-flow studies, rolling- and yawing-moment measurements, and pressure measurements are provided.

Experimental Investigation of the Flow Field Behind an Aspect-Ratio-10 Hydrofoil Near the Water Surface

Description: Report presenting an investigation of the flow field behind a hydrofoil with an 8-inch chord and an aspect ratio of 10; the foil was operating at about 0.75 chord below the free-water surface. The downwash and water surface profiles were measured behind the hydrofoil for a variety of positions of interest. Results regarding surface contours, a comparison of surface profiles with theoretical two-dimensional waves, and downwash are presented.

Performance Characteristics of a Double-Cylindrical-Shroud Ejector Nozzle

Description: Memorandum presenting an investigation of the performance characteristics of a double-shroud ejector for the purpose of evaluating its effectiveness as an exit nozzle. Calculations based on ejector performance data, taken with the ejector discharging into quiescent air, indicate that thrust performance on the order of ideal nozzle thrust may be obtained over a Mach number range of 0.8 to 2.3 from a double-shroud ejector. The results of a simplified theoretical analysis are in fair agreement wit… more

Performance of an annular turbojet combustor having reduced pressure losses and using propane fuel

Description: Report presenting an investigation to develop a high-combustion-efficiency turbojet combustor with pressure losses typical of those encountered in current turbojet engines. A total of 13 air-entry hole modifications was investigated to obtain a combustor design with high combustion efficiencies and a satisfactory outlet radial temperature profile. Results regarding combustor development and the performance of Model 28I are provided.

Wind-Tunnel Investigation of a Modified 1/20-Scale Model of the Convair MX-1554 Airplane at Mach Numbers of 1.41 and 2.01

Description: Report presenting an investigation of a model of the Convair MX-1554 airplane in the 4- by 4-foot supersonic pressure tunnel to evaluate the effects of extending the length of the fuselage afterbody and to provide longitudinal and lateral stability and control data. Results indicated that extension of the fuselage afterbody length caused little change in the minimum longitudinal force coefficient and drag due to lift.

Gust-Tunnel Investigation of the Effect of Leading Edge Separation on the Normal Accelerations Experienced by a 45 Degree Sweptback-Wing Model in Gusts

Description: Report presenting an investigation of a 45 degree sweptback-wing model with interchangeable round and sharp leading edges to determine the effect of leading-edge separation on the loads experienced by the models in gusts. Leading-edge separation was found to increase the gust load, which appeared to vary based on the gust-gradient distance and velocity.

Free-flight-tunnel investigation of the low-speed stability and control characteristics of a model having a fuselage of relatively flat cross section

Description: Report presenting an experimental investigation in the free-flight tunnel to determine the low-speed stability and control characteristics of a model with a fuselage of relatively flat cross section. The model was found to exhibit an erratic behavior in pitch and yaw, which appeared to be due to random trim changes associated with the flow from the forward portion of the flat fuselage. Results regarding the longitudinal stability and control characteristics and lateral stability and control cha… more

Formation of Nitrogen Oxides by Alpha Particle Irradiation of the System N₂-CO₂

Description: Abstract: "The reaction between nitrogen and carbon dioxide, under irradiation with 40 Mev alpha particles from the Berkeley 60 inch cyclotron, was studied at gas temperatures near 50 C and total pressures of about 600 millimeters of Hg, contained in Pyrex capsules. The range of gas compositions investigated included the pure components, as well as mixtures with and without trace oxygen. In all mixtures, a steady state concentration of nitrogen oxides of about 0.15 millimeter was reached after … more

Preliminary Report on Low Columbium: Uranium Corrosion Resistant Alloys

Description: Uranium alloys containing 3 and 6 w/o niobium have been prepared in which the impurity content is rather low. These alloys show very promising resistance to corrosion by water at 260 and 300 degree C. The corrosion resistance is exhibited in degassed water and in water which is saturated with air or oxygen at room temperature before testing.
