Measurements of Heat Transfer and Boundary-Layer Transition on an 8-Inch-Diameter Hemisphere-Cylinder in Free Flight for a Mach Number Range of 2.00 to 3.88
"Measurements of aerodynamic heat transfer have been made along the hemisphere and cylinder of a hemisphere-cylinder rocket-propelled model in free flight up to a Mach number of 3.88. The test Reynolds number based on free-stream condition and diameter of model covered a range from 2.69 x l0(exp 6) to 11.70 x 10(exp 6). Laminar, transitional, and turbulent heat-transfer coefficients were obtained" (p. 1).

Cooling of Gas Turbines, 4 - Calculated Temperature Distribution in the Trailing Part of a Turbine Blade Using Direct Liquid Cooling
A theoretical analysis of the temperature distribution through the trailing portion of a blade near the coolant passages of liquid cooled gas turbines was made. The analysis was applied to obtain the hot spot temperatures at the trailing edge and influence of design variables. The effective gas temperature was varied from 2000 degrees to 5000 degrees F in each investigation.

An evaluation of an aeromechanical method of minimizing servo- missile transfer function variations with flight condition
Report presenting a theoretical investigation to determine the static and dynamic characteristics of a control-surface actuator and missile combination, with primary consideration given to the minimization of the effects of Mach number and altitude.The results indicate that the type of actuator studied in combination with a missile might replace a gain-adjusted acceleration control system. Results regarding the control-system static characteristics, control-system dynamic characteristics, comparison of torposervo and position-servo actuation, and some suggestions for further research are provided.

Analysis of an automatic control to prevent rolling divergence
From Introduction: "The use of automatic controls to reduce the tendency for rolling divergence has been investigated in references 2 and 3. These studies have considered the effect of artificial changes in certain stability derivatives on the rolling divergence, and have shown that increased damping in pitch may be quite effective in reducing the divergent tendency. In the present report, a different type of automatic control is investigated."

Effects of Reynolds number and leading-edge shape on the low-speed longitudinal stability of a 6-percent-thick 45 degree sweptback wing
Report presenting force-test data showing the effects of change in leading-edge radius on the low-speed longitudinal stability of a 6-percent-thick 45 degree sweptback wing of aspect ratio 3 for several ranges of Mach and Reynolds numbers. The results indicated that as the airfoil sections were thinned at the nose, separation effects occurred at lower values of lift coefficient.

Lateral Control Required for Satisfactory Flying Qualities Based on Flight Tests of Numerous Airplanes
Report presents the results of an analysis made of the aileron control characteristics of numerous airplanes tested in flight by the National Advisory Committee for Aeronautics. By the use of previously developed theory, the observed values of pb/2v for the various wing-aileron arrangements were examined to determine the effective section characteristics of the various aileron types.

Some Effects of Heat Transfer at Mach Number 2.0 at Stagnation Temperatures Between 2,310 and 3,500 Degrees R on a Magnesium Fin With Several Leading-Edge Modifications
Report presenting testing of four models of a thin magnesium fin, with the leading edge swept back 35 degrees, of a type used to stabilize the first stages of rocket-propelled multistage hypersonic models. The investigation was carried out to determine some effects of aerodynamic heating at high stagnation temperatures on the leading edges of fins and to determine the relative effectiveness of several leading-edge protective methods. The fins tested included a basic fin, a fin with a blunt leading edge, a fin with a blunt leading edge wrapped with Inconel, and a fin with a blunt leading edge made of stainless steel.

Heat Transfer and Boundary-Layer Transition on a Highly Polished Hemisphere-Cone in Free Flight at Mach Numbers Up to 3.14 and Reynolds Numbers Up to 24 X 10(Exp 6)
"A highly polished hemisphere-cone having a ratio of nose radius to base radius of 0.74 and a half-angle of 14.5 degrees was flight tested at Mach numbers up to 4.70. Temperature and pressure data were obtained at Mach numbers up to 3.14 and a free-stream Reynolds number of 24 x 10(exp 6) based on body diameter. The nose of the model had a surface roughness of 2 to 5 microinches as measured with an interferometer" (p. 1).

Reexamination of Agency Reporting Requirements: Annual Process Under the GPRA Modernization Act of 2010 (GPRAMA)
On January 4, 2011, the GPRA Modernization Act of 2010 (GPRAMA) became law. The acronym "GPRA" in the act's short title refers to the Government Performance and Results Act of 1993 (GPRA 1993), a law that GPRAMA substantially modified. Some of GPRAMA's provisions require agencies to produce plans and reports for a variety of audiences that focus on goal-setting and performance measurement. Other provisions, by contrast, establish an annual process to reexamine the usefulness of certain reporting requirements. The report concludes by looking potential issues for Congress in two categories.

Tribal Criminal Jurisdiction over Non-Indians in the Violence Against Women Act (VAWA) Reauthorization and the SAVE Native Women Act
A report looking at incidences of violence against women of American Indian ethnicity in relation to legal jurisdiction. American Indians experience violent crimes at a rate much higher than the general population. This trend carries over to domestic violence: American Indian women experience domestic and dating violence at more than twice the rate of non-Indian women. Most of this violence involves an offender of a different race. This fact creates a jurisdictional problem because tribal courts do not have criminal jurisdiction over crimes committed within the tribe's jurisdiction by non-Indians.

Navy Littoral Combat Ship (LCS) Program: Background, Issues, and Options for Congress
This report provides background information and potential issues for Congress on the Littoral Combat Ship (LCS), a relatively inexpensive Navy surface combatant equipped with modular "plug-and-fight" mission packages. The Navy's proposed FY2012 budget requests funding for the procurement of four LCSs. Current issues for Congress concerning the LCS program include changes or potential changes to the composition of LCS mission modules announced by the Navy in January 2011, the combat survivability of the LCS, and hull cracking on LCS-1. Congress's decisions on the LCS program could affect Navy capabilities and funding requirements, and the shipbuilding industrial base.

Iran: U.S. Concerns and Policy Responses
This report discusses the effects of economic sanctions against Iran; support to the Iranian democracy movement; and opposition against Iranian human rights violations and Iranian support for Syrian human rights violations. The Obama Administration identifies Iran as a major threat to U.S. national security interests. The sense of imminent crisis with Iran which greeted the beginning of 2012 follows three years in which the Obama Administration first offered Iran's leaders consistent and sustained engagement in exchange for limits to its nuclear program but, since 2010, has emphasized pressuring Iran through economic sanctions.
