Development Of Helicopter Flight Path Models, Alfred Fermelia, Donald A. Gyorog, V. J. Flanigan

Mechanical and Aerospace Engineering Faculty Research & Creative Works

The objective of this paper is to present general techniques for simulating helicopter flight trajectory response. During flight the pilot manipulates the controls either to trim the helicopter for steady flight by balancing the external forces and moments or to produce a desired maneuver by controlling the unbalance of these forces and moments. Discussions of the physical phenomena involved with the aerodynamics of the rotors and fuselage are given in [1] through [3]. The simulated control function will be composed forward-aft cyclic, lateral cyclic, pedal, and collective. This control will be represented by the vector

Void-Strengthening In Aluminum And Its Nature, P. G. Manusmare, Hollis P. Leighly

Materials Science and Engineering Faculty Research & Creative Works

Temperature and strain rate dependence of yield strength were used to analyze the nature of aluminum strengthened by the formation of voids. Aluminum rods 99.999% pure were quenched and heat treated to form voids with an approximate density of 1013-1014 voids/cm3. Voids in selected samples were observed by electron microscopy. The yield strength of the void strengthened samples was measured at various temperatures from 77 to 593 K and at two strain rates, 3.33 x 10-2/s and 1.67 x 10-3/s. Tests at room temperature and at 77 K were made at various strain rates. The similarity of Coulomb's approach to …

Feasibility Of Integrated Ocean Thermal Gradient-Nuclear Plants For The Production Of Electrical Power, Frank Ferrer, Donald Sasscer

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

A study was made of the feasibility of integrating an ocean thermal energy conversion (OTEC) electrical power plant with a nuclear power plant. The integration was such that the waste heat of the nuclear plant was used to augment the thermal efficiency of the OTEC plant. The study was performed for three shore line sites of Puerto Rico where deep cold water is found between 2 and 10 miles from shore.

Radiative Lifetimes Of Some Group Ii Ions By The Hanle Effect In A Fast-Flowing Helium Afterglow, F. H.K. Rambow, Laird D. Schearer

Physics Faculty Research & Creative Works

Radiative lifetimes of the first P322 state of Mgu, Cau, Znu, Sru, Cdu, and Bau are reported as measured by the Hanle effect in a fast-flowing helium afterglow. They are, respectively, 3.65(0.12), 6.61(0.30), 2.4(0.3), 6.64(0.10), 2.86(0.25), 6.78(0.40) in units of 10-9 sec. The ions in the afterglow are created by Penning ionization of the neutral metal atoms, thus providing a steady-state, field-free region for observation. Comparisons are made with measurements by other methods, and discrepancies are discussed. © 1976 The American Physical Society.

Physics Faculty Research & Creative Works

The radiative lifetimes of the 17992-,25068-,28857-, 37414-, 40564-, and 44017-cm-1 neutral levels and the 30392-cm-1 ion level of Yb have been measured by the Hanle method in a fast-flowing He system. The lifetimes (in units of 10-9 sec) were found to be 820(20), 5.12(0.12), 14.4(0.4), 77.4(6.0), 9.32(0.6), 39.1(3.5), and 5.8(0.6), respectively. In a flowing system with He as a buffer gas the alignment depolarization cross sections with Yb were obtained and are reported here for the first time.

Surface Electromagnetic Waves With Damping. I. Isotropic Media, G. S. Kovener, Ralph William Alexander, Robert John Bell

Physics Faculty Research & Creative Works

Surface-Electromagnetic-Wave Dispersion Curves Are Usually Calculated using a Simple Equation Derived from Maxwell's Equations and Boundary Conditions. When Complex Dielectric Functions Are Used for the Two Media, the Component of the Propagation Vector Along the Surface, Kx, Becomes Infinite as the Frequency Approaches the Surface Polariton Frequency Ωs If Ω is Considered Complex and Kx is Real. on the Other Hand, If Kx is Considered Complex and Ω Real, the Dispersion Curves Bend Back Toward Smaller Kx as Ω Approaches Ωs. We Have Previously Demonstrated that Both Types of Behavior Can Be Obtained from Attenuated-Total-Reflection Measurements of Silver. We Now …

The Internal Chemical Shift - A Key To Bonding In Aromatic Molecules. 2. Substituent Effects On The Carbon-13 Magnetic Resonance Spectra Of The 1,4-Disubstituted Benzenes, Donald W. Beistel, W. Dan Edwards

Chemistry Faculty Research & Creative Works

Carbon-13 magnetic resonance shifts were determined for six families of 1,4-disubstituted benzenes. Linear least-squares correlations between the internal shifts of the families suggest an additivity relationship for 13C substituent effects at all four nonidentical ring carbons and at the α position when one of the substituents has a central carbon. The correlation of 1H and 13C shifts for these compounds is also linear, implying that the additivity relationships derived in a previous 1H study can be generalized to 13C.

Structural Stability Research Council: Proceedings 1976, Structural Stability Research Council

CCFSS Library (1939 - present)

One of the purposes of the Council is to maintain a forum where problems related to the design and behavior of columns and other compression elements in metal structures can be presented for evaluation and discussion. The Annual Technical Session provides an opportunity to carry out this function. The 1976 Annual Technical Session was held on March 2 and 3 at the SheratonBiltmore Hotel in Atlanta, Georgia. Fifty-five persons attended the session and nineteen papers were delivered. A panel discussion on "New Ideas on Stability of Multistory Buildings" was held in the evening of March 2, 1976. the panelists were …

Influence Of Turbidity On The Stratification Development Of A Deep Water Reservoir., David Allen Prouty

Masters Theses

"The influence of turbidity on the diurnal temperature distribution and thermocline development in a deep water impoundment which is exposed to heating and cooling loads by convection, evaporation, and radiation is examined analytically. The diurnal behavior of the solar load, directional and spectral, is used with an isotropic multiple scattering model to simulate the attenuation of solar flux by turbid water. The diurnal behavior of the ambient temperature, humidity and wind speed were mathematically modeled to simulate the local (Phelps Co.) spring time of the year. The combined conduction and radiation energy transfer through the water was treated as a …

The Energy Conservation Implications Of Master Metering Of Electric Service In Apartments, Gordon Gross

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

A study has been made of the difference in electricity usage between residents of "Electricity included" apartments and those tenants who pay individual "light bills." The factors which influence owners' and builders' choices of metering service are discussed in detail.

Data taken from over 100 apartment buildings or complexes in 10 major U.S. metropolitan areas and from over 50 major electric power companies are used as the basis for the reported results. Contractors estimates of the costs to convert building service from master to individual meter and some bases for these costs are presented.

Self-Consistency In Estimating Future Electrical Energy Consumption, W. D. Devine Jr., C. C. Calligan, O. D. Osborne

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

A socio economic computer simulation model for the State of Oregon is described. The Oregon State Simulation Model (OSSIM) includes a thirty-seven sector model of electrical energy consumption. Coupling between this model and the OSSIM ensures self-consistent scenarios of socio economic phenomena which underlie energy consumption. One of the purposes of this effort is to help state-level decision makers understand the determinants of electricity consumption within a context of changing economic conditions.
