Manual 'free' welding of 2014-t6 aluminum( Book )

1 edition published in 1957 in English and held by 1 WorldCat member library worldwide

Test results indicate that repair welding will increase the width of the heat-affected zone. The increased width results in lower design allowables for the welded joint than in straight welding. The average tensile strength of the repaired Set 1 specimens is higher than the original straight specimens. A probable explanation is that the severely induced stresses on the original specimens may have been reduced during repair welding. As in previous welding tests, the results are inconsistent. This is largely attributed to operator variables. (Author)
Transient tests of the ylr 87-aj-5 rocket engine turbopump with the redesigned fuel pump and associated propulsion equipment( Book )

1 edition published in 1964 in English and held by 1 WorldCat member library worldwide

Two tests were conducted with suction pulsing and one test was conducted with discharge pulsing. The redesigned pump exhibited a significant advantage over the production pump for the parameters which are pertinent to the analysis and re duction of the Titan II longitudinal oscillation. Use of the redesigned fuel pump on the overall system stability must be analyzed in conjunction with the oxidizer system configuration. (Author)

Main tank injection for packaged liquid missiles. volume i. systems analysis and component test( Book )

1 edition published in 1966 in English and held by 1 WorldCat member library worldwide

A study is being conducted on the use of main tank injection (MTI) for pressurization of packaged liquid missile propellant tanks. The propellants for this short-range, air-to-ground weapon system are MHF-5 fuel and Compound A oxidizer. This report presents the analytical evaluation of propellant orientation subsystems and MTI performance together with the results of limited tests on the compatibility of flexing components with hot Compound A. Analyses were conducted to define the vehicle propulsion system configuration and a program reference mission
Manual and repair welding of chemically milled 2014-t6 aluminum sheeting( Book )

1 edition published in 1957 in English and held by 1 WorldCat member library worldwide

A 2 inch wide land 0.100 in. thick, will fully retain the weld heat-affected zone of repaired welds (based on hardness data). Parent metal properties are only slightly affected by weld heat on repairs of 1.5 inch lands. Values of 59,000 psi can be expected with 90 percent confidence for repaired 1.5 inch lands. If 95 and 99 percent confidence is required, expected values for repaired 1.5 inch lands are 57,800 and 55,400 psi. If land widths of 1.625 inches and above are used, parent metal strength can be expected for manual welds followed by repair welds
Main tank injection for packaged liquid missiles phase i report. volume ii. systems feasibility testing( Book )

1 edition published in 1967 in English and held by 1 WorldCat member library worldwide

A two-phase program is being conducted to establish feasibility and demonstrate practicality of using main tank injection (MTI) for pressurization of packaged liquid missile (PLM) propellant tanks. The propellants for this short-range, air-to-ground weapon system are MHF-5 fuel and Compound A oxidizer. An analysis of various simplified MTI pressure control techniques is also included. Two half-scale, screen-type propellant retention devices were designed, fabricated, and tested under the projected vibration/slosh and acceleration environments of PLM. These devices, required to ensure gas-free propellant expulsion, were the propellant reservoir and lined dome segment configurations previously selected during systems analysis. The environmental testing, performed with propellant simulants, demonstrated that both configurations could retain propellant without leakage at acceleration and vibration levels in excess of those required for PLM. Based on cost projections and versatility of the devices for PLM, the propellant reservoir was selected over the lined dome segment for the full-scale Phase II demonstration tests. The feasibility of employing MTI pressurization for MHF-5 fuel and Compound A oxidizer was investigated with a specially constructed test system
Evaluation of 6061-t6 to 2014-t6 and 6061-t6 to 6061-t6 aluminum alloy welds( Book )

1 edition published in 1959 in English and held by 1 WorldCat member library worldwide

This weld-evaluation program was conducted by simulating the cap-to-skirt weld junction, the cap-toskirt T-weld junction, and the cap-to-outlet weld, and testing and examining these simulated welds for tensile tukon microhardness, and metallographic data. In addition special studies were made of welding under stress, mismatch of material thickness, and weld heat-affected zones. Confidence levels of 99.5%, 99.0%, and 95.0% for design application on fusion-, lap-, and T-welds are included. This report substantiates previous evidence that microcracks will not result from a 2014-T6 to 6061-T6 combination, provided the alloys are fusion- or T-welded and not lap-welded. This report also substantiates the fact that thickness mismatch in similar lap-welded metal junctions does not produce microcracks. Minimum ultimate tensile strength (UTS) data reveal that the use of thinner-than-anticipated dome material may be possible. Data on weld heat-affected zones prove that the heataffected zone of 6061-T6 is greater than that of 2014-T6 and furnish the land widths necessary to restrict heat flow during welding of fusion and lap welds.

Preliminary evaluation of direct-current manual welding of 2014-t6 aluminum( Book )

1 edition published in 1958 in English and held by 1 WorldCat member library worldwide

Roark Engineering d-c welding is only equal or inferior to Martin a-c welding; Direct-current filler-arc welding holds considerable promise over a-c welds because: The weld heat-affected zone decreases noticeably, using either 4043 or 5456 aluminum filler rods; Weld strengths are equal or superior under the same conditions; Using 5456 filler rod, a finer grained weld structure and higher initial weld hardness are achieved. (Higher hardness and finer grain structure could cause weld cracking problems.) (Author)
HETEROGENEOUS PROPELLANT STORAGE TESTING( Book )

1 edition published in 1966 in English and held by 1 WorldCat member library worldwide

The long-term storability of hydrazine-aluminum gelled propellants is uncertain due to propellant decomposition. The problem was investigated in three phases: (1) bulk expansion due to gases trapped in the gel; (2) pressure rise due to gas evolution and bulk expansion of the propellant; and (3) scaling tests to determine the effect of size on gas evolution rate as measured by pressure rise. Nine chemicals were tested as additives for reducing gas evolution. None lowered the rate significantly below that of the hydrazine control, but two, toluene and silicon dioxide, were selected for trial in the scaling tests. These tests, even without inhibitor, showed a marked decrease of gas evolution rate with increasing size. When extrapolated to 10,000 gal., the gas evolution rate is of the order of 10 to the -6th power sccm/lb-minute. Before these extrapolated results are accepted, it is recommended that further work be accomplished using larger test containers to confirm the scaling effect. (Author)

An analytical study of the effects of oblateness on satellite orbits( Book )

1 edition published in 1960 in English and held by 1 WorldCat member library worldwide

This report contains an analytical study of the short term effects of planetary oblateness on the path of a satellite that is under the sole influence of gravitational attraction. Analytical solutions of the equations of the path, valid to the first order in the oblateness parameter J, are determined following the method of Lindstedt. The initial conditions considered in this report require that the satellite be initially at an apse in the equatorial plane, but the inclination and the eccentricity are unrestricted. Subsequent reports will consider: (1) initial positions not in the equatorial plane; and (2) the escape path from an oblate planet. Both analytical expressions and numerical results are given for the radial position, speed, angular momentum, deviation from the initial plane of motion, rate of nodal regression, and the rate of apsidal advance of a satellite. In addition, the injection speed required for prescribed apses is derived

1 edition published in 1958 in English and held by 1 WorldCat member library worldwide

Based on test results, the following conclusions were reached: For a 99-percent confidence level, the following are the expected design parameters when stops, starts, tacks ground out, and tacks welded over are included: 40,000 psi -- 0.05-in. material; 36,400 psi -- 0.125-in. material; 36,400 psi -- 0.25-in. material; Tensile elongations of 7.5 percent are typical for 0.05- and 0.125-in. material; however, the minimum elongations are 8.5 percent for 0.25-in. material; The recommended heat treatment for the bimetal junction is solution heat treatment at 950 = 10 deg F with a water quench, followed by an aging treatment at 350 = 10 deg F for eight hours, and subsequent cooling in air. The soaking times required for various sheet thicknesses are: <0.032 in., 20 minutes;> 0.032-in. but <0.10 in., 45 minutes; and> 0.10 in., 60 minutes. (Author)
