Preliminary evaluation of the performance of a uniflow two-stroke-cycle spark-ignition engine combined with a blowdown turbine and a steady-flow turbine
Report presenting calculations based on a theoretical analysis for a composite engine consisting of a uniflow two-stroke-cycle spark-ignition engine, a compressor, a blowdown turbine, and a steady-flow turbine. Operation of the engine is considered for four cases of gas mixtures and steady-flow turbine temperatures.

Flight Investigation at Low Angles of Attack to Determine the Longitudinal Stability and Control Characteristics of the Sidewinder Missile at Mach Numbers from 1.2 to 2.1
At the request of the Bureau of Ordnance, Department of the Navy, the Langley Pilotless Aircraft Research Division has initiated a program to investigate the general aerodynamic characteristics of the Naval Ordnance Test Station's SIDEWINDER missile. The model used in the flight test presented herein was a full-scale, rocket-propelled test vehicle. This paper presents the results from a flight test investigation using the pulsed-control technique to determine the static and dynamic longitudinal stability and control derivatives and drag data for a canard-missile configuration.

Flight Measurement of Aerodynamic Loads and Moments on an External Store Mounted Under the Wing of a Swept-Wing Fighter-Type Airplane
Report discussing an investigation of external-store characteristics using a 245-gallon external fuel tank mounted under a wing of a North American F-86A airplane. The store normal force was found to increase abruptly on penetration of the buffet boundary. Information about the normal- and side-load distribution and integrated force and moment coefficients is provided.

Evaluation of End- and Radial-Burning Solid Fuels in Ram Jets Mounted in a Free Jet at Mach Numbers of 2.0, 2.2, and 2.3
Report presenting testing of two types of solid fuels in a 6.5-inch-diameter ram-jet engine mounted in a free supersonic jet at several Mach numbers. Results regarding radial-burning fuel, end-burning fuel, and a comparison of the two are provided. Unlike in previous testing, no fuel breakup was noted due to recently developed molding techniques.

Applications of auxiliary air injectors to supersonic wind tunnels
Report presenting a discussion of the adverse effects of high compression ratio requirements for supersonic wind tunnels as well as the use of second throats for alleviating those effects. The results indicated that an auxiliary air-injector system can reduce starting and running compression ratios as compared to a conventional wind tunnel with a divergent diffuser.

Fuel spray and flame formation in a compression-ignition engine employing air flow
"The effects of air flow on fuel spray and flame formation in a high-speed compression-ignition engine have been investigated by means of the NACA combustion apparatus. The process was studied by examining high-speed motion pictures taken at the rate of 2,200 frames a second. The combustion chamber was of the flat-disk type used in previous experiments with this apparatus. The air flow was produced by a rectangular displacer mounted on top of the engine piston. Three fuel-injection nozzles were tested: a 0.020-inch single-orifice nozzle, a 6-orifice nozzle, and a slit nozzle" (p. 281).

The effect on airplane performance of the factors that must be considered in applying low-drag cowling to radial engines
From Summary: "This report presents the results of flight tests with three different airplanes using several types of low-drag cowling for radial air-cooled engines. The greater part of the tests were made with a Curtiss XF7Cc-1 (Sea Hawk) with a 410 horsepower. Wasp engine, using three fuselage nose shapes and six types of outer cowling. The six cowlings were: a narrow ring, a wide ring, a wide cowling similar in the original NACA cowling, a thick ring incorporating an exhaust collector, a single-surface cowling shaped like the outer surface of the exhaust-collector cowling, and polygon-ring cowling, of which the angle of the straight sections with the thrust line could be varied over a wide range."

Comparison of Alcogas Aviation Fuel With Export Aviation Gasoline
Mixtures of gasoline and alcohol when used in internal combustion engines designed for gasoline have been found to possess the advantage of alcohol in withstanding high compression without "knock" while retaining advantages of gasoline with regard to starting characteristics. Test of such fuels for maximum power-producing ability and fuel economy at various rates of consumption are thus of practical importance, with especial reference to high-compression engine development. This report discusses the results of tests which compares the performance of alcogas with x gasoline (export grade) as a standard.

Defense: FY2012 Budget Request, Authorization and Appropriations
This report discusses legislative action that applied the Budget Control Act (BCA)-mandated spending reduction to FY2012 defense funding legislation was taken by the Senate Appropriations Committee on September 7, 2011, when it adopted discretionary spending ceilings for each of its 12 subcommittees that required the Defense Subcommittee to cut $25.9 billion from the President's request for programs funded by the DOD Appropriations bill. On September 15, the Senate Appropriations Committee reported an amended version of the House-passed DOD Appropriations bill (H.R. 2219) that would cut $29.3 billion from the Administration request.

Clean Air Act Issues in the 109th Congress
The courts and the executive branch face major decisions on clean air issues in 2006, with Congress more likely playing an oversight role. One focus is EPA's Jan. 17 2006 proposal to strengthen air quality standards for fine particles, which are estimated to cause tens of thousands of premature deaths annually. Whether the proposal is supported by the available science and what impact its implementation would have likely issues of concern. Other issues of continuing interest are EPA's 2005 decisions limiting interstate transport of air pollution and establishing cap-and-trade systems for emissions from coal-fired power plants, and the agency's proposed changes to New Source Review.
