Low-speed wind tunnel investigation of the lateral-directional characterisitcs of a large-scale variable wing-sweep fighter model in the high-lift configuration

The low-speed characteristics of a large-scale model of the F-14A aircraft were studied in tests conducted in the Ames Research Center 40- by 80-Foot Wind Tunnel. The primary purpose of the present tests was the determination of lateral-directional stability levels and control effectiveness of the aircraft in its high-lift configuration. Tests were conducted at wing angles of attack between minus 2 deg and 30 deg and with sideslip angles between minus 12 deg and 12 deg. Data were taken at a Reynolds number of 8.0 million based on a wing mean aerodynamic chord of 2.24 m (7.36 ft). The model configuration was changed as required to show the effects of direct lift control (spoilers) at yaw, yaw angle with speed brake deflected, and various amounts and combinations of roll control

COMMUNITY ECONOMIC EFFECTS OF POPULATION CHANGE IN THE MID-CONTINENT REGION

Population estimates for counties in the Mid-Continent Region were compiled by multi-county economic area for 1950, 1960, 1970, 1974, and 1976. Net migration estimates were compiled, also, by economic area. Finally, community economic effects for a metropolitan area and a nonmetropolitan area in Minnesota were estimated in terms of local government and personal income and expenditures and their relation to population change.Community/Rural/Urban Development,

ECONOMIC IMPORTANCE OF EXPORT-PRODUCING INDUSTRY IN MINNESOTA

In this report, the role and importance of export-producing industries in Minnesota are discussed. Major emphasis is on agricultural-related industries and their economic importance to the State in value of gross output and contribution to gross state product.Community/Rural/Urban Development, International Relations/Trade,

ECONOMIC IMPORTANCE OF AGRICULTURE-RELATED INDUSTRY IN MINNESOTA

This report is the third in a series on interindustry and interregional relationships and their implications for the economy of Minnesota and its substate development regions. In this report, the role and importance of agriculture-related industries in Minnesota are discussed. A total of 19 agriculture and 35 food products manufacturing industries are identified as the principal agriculture-related industries in the state and the nation. Their interindustry and interregional (Minnesota and rest-of-nation) linkages are derived for the 1977 calendar year.Community/Rural/Urban Development,

MINNESOTA'S ECONOMIC GROWTH IN RECESSION AND RECOVERY: PART I

This report presents statistical reference series for the study and projection of Minnesota's economic outlook in the 1980's. The reference series serve as baseline forecasts for the assessment on Minnesota's job and income prospects in its basic industries, including agriculture, forestry, mining, manufacturing and services for nonresidents in work and leisure activities. In Part I, two sets of baseline forecasts are presented, namely, short-term quarter-year and long-term five-year forecasts of industry employment and personal earnings and income.Community/Rural/Urban Development,

Enhancement of Superconductivity in Disordered Films by Parallel Magnetic Field

We show that the superconducting transition temperature T_c(H) of a very thin highly disordered film with strong spin-orbital scattering can be increased by parallel magnetic field H. This effect is due to polarization of magnetic impurity spins which reduces the full exchange scattering rate of electrons; the largest effect is predicted for spin-1/2 impurities. Moreover, for some range of magnetic impurity concentrations the phenomenon of {\it superconductivity induced by magnetic field} is predicted: superconducting transition temperature T_c(H) is found to be nonzero in the range of magnetic fields $0 < H^* <= H <= H_c$.Comment: 4 pages, 2 figure
