[Letter from S. H. Thornhill to Linnet Moore, June 6, 1899]

Description: This is a letter from the Charles B. Moore Collection. It is written by S. H. Thornhill to Linnet Moore. In this letter, Thornhill discusses establishing a line of communication with Linnet through correspondences. He states that he had hoped to hear from Linnet after she left Waxahachie, but understands that her studies took priority of writing letter. Now that school is out, he mentions, it is about time she write him a few lines. He details that all the family is well, urges Linnet to visit … more

Analysis of Performance of Jet Engine From Characteristics of Components 1: Aerodynamic and Matching Characteristics of Turbine Component Determined With Cold Air

Description: "The performance of the turbine component of an NACA research jet engine was investigated with cold air. The interaction and the matching of the turbine with the NACA eight-stage compressor were computed with the combination considered as a jet engine. The over-all performance of the engine was then determined. The internal aerodynamics were studied to the extent of investigating the performance of the first stator ring and its influence on the turbine performance" (p. 397).

A fuel-distribution control for continuous-flow manifold injection on reciprocating engines

Description: "A fuel-distribution control for continuous-flow manifold injection on reciprocating engines is described. A method is installation of the control on an engine is suggested. The device controlled the flow to four spring-loaded nozzles within 2 percent of perfect distribution over a wide range of fuel-flow rates and the distribution was practically unaffected by uneven discharge-nozzle pressures" (p. 1).

An Investigation of the Low-Speed Characteristics of Two Sharp-Edge Supersonic Inlets Designed for Essentially External Supersonic Compression

Description: Report presenting an investigation of two sharp-edge annular inlets with conical central bodies at low airspeeds in the propeller research tunnel to obtain information concerning the surface-pressure, drag, and pressure-recovery characteristics of the inlets at subsonic flight. Results regarding the nose and inner surface of the diffuser, inlet lips, minimum surface pressures and critical Mach numbers, pressure surveys in inlets, and pressure surveys in diffusers are provided.

Some pressure-distribution measurements on a swept-wing at transonic speeds by the NACA wing-flow method

Description: Report presenting results of chordwise pressure-distribution measurements on a 45 degree sweptback wing at transonic speeds. The two stations for measuring were located at the 18 percent chord from the root and the 87 percent chord. The changes in pressure distribution with Mach number did not indicate any appreciable net loss in section lift, but did indicate large increases in the section drag and diving moment.

The Effect of Blade-Section Thickness Ratios on the Aerodynamic Characteristics of Related Full-Scale Propellers at Mach Numbers Up to 0.65

Description: Report discussing an investigation of two full-scale NACA propellers at a range of blade angles and at speeds of up to 500 miles per hour. The results are compared to previous investigations of five NACA propellers to evaluate the effects of blade-section thickness ratios on propeller characteristics.

Investigation of downwash and wake characteristics at a Mach number of 1.53 2: triangular wing

Description: Report presenting the results of an experimental investigation of the downwash and wake characteristics behind a triangular plan-form wing in a supersonic stream. Measurements were made of the variation of downwash angle with angle of attack at several positions within the induced flow field. Results regarding the spanwise variation of the induced stream angle, rate of change of downwash at zero lift, variation of downwash with angle of attack, and wake are provided.

Material balance flowsheet Redox Production plant

Description: The attached material balance flowsheet for the proposed Redox Production plant is based on the two chemical flowsheets submitted by R.B. Richards of the Technical Division in HW 13,320 (INDC-3130) and HW 13,452 (INDC 3176). Production rates for the plant have been assumed as 2.5 short tone U per day (including a maximum of 0.75 short tons of U from stored Bi PO{sub 4} waste) and 19 kg. Pu per month (633 gms/day) as established by the Redox Committee. The flowsheets for preparation of solvent e… more

Performance of Axial-Flow Supersonic Compressor of XJ55-FF-1 Turbojet Engine 2 - Performance of Inlet Guide Vanes as Separate Component

Description: "The inlet guide vanes for the supersonic compressor of the XJ55-FF-1 engine were studied as a separate component in order to determine the performance prior to installation in the compressor test rig. Turning angles approached design values, and increased approximately to through the inlet Mach number range from 0.30 to choke. A sharp break in turning angle was experienced when the choke condition was reached" (p. 1).

Performance of J33 turbojet engine with shaft-power extraction 3: turbine performance

Description: From Summary: "The performance of the turbine component of a J33 turbojet engine was determined over a range of turbine speeds from 8000 to 11,500 rpm.Turbine-inlet temperature was varied from the minimum required to drive the compressor to a maximum of approximately 2000 degrees R at each of several intermediate turbine speeds. Data are presented that show the horsepower developed by the turbine per pound of gas flow."
