New Markets Tax Credit: The Credit Helps Fund a Variety of Projects in Low-Income Communities, but Could Be Simplified

New Markets Tax Credit: The Credit Helps Fund a Variety of Projects in Low-Income Communities, but Could Be Simplified

Date: January 29, 2010
Creator: United States. Government Accountability Office.
Description: A letter report issued by the Government Accountability Office with an abstract that begins "The Treasury Department's Community Development Financial Institutions (CDFI) Fund awarded $26 billion in New Markets Tax Credits (NMTC) through 2009 for investment in low-income communities. The NMTC allows investors to claim a tax credit totaling 39 percent of their investment in Community Development Entities (CDE) over 7 years which CDEs reinvest in qualified communities. This mandated report (1) describes where and how CDEs are using NMTCs, (2) assesses how CDEs use NMTCs to offer favorable financing terms to low-income community businesses and describes options for simplifying the NMTC, (3) describes how, if at all, NMTC investments support low-income community development, and (4) determines how effective IRS and the CDFI Fund have been in monitoring NMTC compliance. GAO analyzed CDFI Fund and CDE data, did case studies of CDEs, and interviewed relevant experts."

A new method for the prediction of airplane performance

A new method for the prediction of airplane performance

Date: February 1, 1929
Creator: Lesley, E P & Reid, E G
Description: A new method for the prediction of airplane performance in level and climbing flight, together with complete information regarding propeller speeds, is described in this report. Developed from Bairstow's system and making use of American absolute coefficients, this method has advantages of simplicity and brevity.

New method of calculating the power at altitude of aircraft engines equipped with superchargers on the basis of tests made under sea-level conditions

New method of calculating the power at altitude of aircraft engines equipped with superchargers on the basis of tests made under sea-level conditions

Date: July 1, 1941
Creator: Sarracino, Marcello
Description: The present article deals with what is considered to be a simpler and more accurate method of determining, from the results of bench tests under approved rating conditions, the power at altitude of a supercharged aircraft engine, without application of correction formulas. The method of calculating the characteristics at altitude, of supercharged engines, based on the consumption of air, is a more satisfactory and accurate procedure, especially at low boost pressures.

New Method of Determining the Polar Curve of an Airplane in Flight

New Method of Determining the Polar Curve of an Airplane in Flight

Date: March 1, 1945
Creator: Yegorov, B. N.
Description: A fundamental defect of existing methods for the determination of the polar of an airplane in flight is the impossibility of obtaining the thrust or the resistance of the propeller for any type airplane with any type engine. The new method is based on the premise that for zero propeller thrust the mean angle of attack of the blade is approximately the same for all propellers if this angle is reckoned from the aerodynamic chord of the profile section. This angle was determined from flight tests. Knowing the mean angle of the blade setting the angle of attack of the propeller blade at zero thrust can be found and the propeller speed in gliding obtained. The experimental check of the new method carried out on several airplanes gave positive results. The basic assumptions for the construction of the polars and the method of analyzing the flight data are given.

New method of extrapolation of the resistance of a model planing boat to full size

New method of extrapolation of the resistance of a model planing boat to full size

Date: March 1, 1942
Creator: Sottorf, W
Description: The previously employed method of extrapolating the total resistance to full size with lambda(exp 3) (model scale) and thereby foregoing a separate appraisal of the frictional resistance, was permissible for large models and floats of normal size. But faced with the ever increasing size of aircraft a reexamination of the problem of extrapolation to full size is called for. A method is described by means of which, on the basis of an analysis of tests on planing surfaces, the variation of the wetted surface over the take-off range is analytically obtained. The friction coefficients are read from Prandtl's curve for turbulent boundary layer with laminar approach. With these two values a correction for friction is obtainable.

A new method of studying the flow of the water along the bottom of a model of a flying-boat hull

A new method of studying the flow of the water along the bottom of a model of a flying-boat hull

Date: February 1, 1940
Creator: Ward, Kenneth E
Description: A new method of studying the flow of the water along the bottom of a model of a flying-boat hull is described. In this method, the model is fitted with a transparent bottom and is divided down the center line by a bulkhead. The flow is observed and photographed through one-half of the model by means of the diffused illumination from a battery of lamps contained in the other half of the model. Photographs of the flow, particularly of the changes that occur when the step ventilates, are shown. The results of the present investigation indicate that the method has considerable promise, chiefly in connection with motion-picture studies.

A new method of testing in wind tunnels

A new method of testing in wind tunnels

Date: August 1, 1921
Creator: Margoulis, W
Description: Now, in existing wind tunnels, using a horsepower of 100 to 300, the models are generally made to a 1/10 scale and the speed is appreciably lower than the speeds currently attained by airplanes. The Reynolds number realized is thus 15 to 25 times smaller than that reached by airplanes in free flight, while the ratio of speed to the velocity of sound is between a third and three quarters of the true ratio. The necessary increases in either the diameter of the wind tunnel or the velocity of the airstream are too costly. However, the author shows that it is possible to have wind tunnels in which the Reynolds number will be greater than that now obtained by airplanes, and in which the ratio of the velocity to the velocity of sound will also be greater than that realized in practice, by employing a gas other than air, at a pressure and temperature different from those of the surrounding atmosphere. The gas is carbonic acid, a gas having a low coefficient of viscosity, high density, and a low ratio of specific heat. The positive results of using carbonic acid in wind tunnel tests are given.
