An extensive survey of current and future airframe construction materials and coolants was conducted, so that the most promising candidates could be examined for cooled-panel, cooling-system and airframe concepts. Consideration was given to over 100 structural materials, 50 coolants, 6 classes of structural panel concepts, 4 classes of thermal panel concepts with numerous variations, and 3 overall cooled airframe design approaches, including unshielded, shielded, and dual temperature types. The...

The data analyzed was from an auroral rocket probe, AF 10.312, launched in 1974 from Poker Flats, Alaska. The instrumentation is described in an AF Geophysics Laboratory Technical Report AFCRL-TR-75-0023. The data were from both a low energy and high energy electron spectrometer, which measured fluxes at 1-100 eV and 1-20 KeV respectively. The rocket flight was north along a geomagnetic meridian, crossing the Harang discontinuity and several non optical auroral arcs. Data represents the first...

The goal of this project was to explore THz technologies for wider bandwidth communications and sensing for DoD systems. More specifically the objective was to develop solid state THz sources for operation in the range between 0.3 to 10 (1 millimeter to 30 micrometer) mainly for aerospace communications and atmospheric sensing; and potentially, short-range terrestrial and airborne communications and near-object analysis. The focus was on all solid-state high efficiency, high power, directional...

Ideally, an adaptive optical control system would have instantaneous temporal response and infinite spatial bandwidth. In real systems, the response time of the adaptive optical control system is limited by the integration time of the wave front sensor, the computational time of the control algorithm, and the actuator response time. Additionally, finite inter actuator spacing limits the deformable mirror's ability to reproduce spatial frequencies having a period less than twice this spacing....

X-ray photoelectron spectroscopy (XPS) has been used to study the surface composition and chemistry of Long Duration Exposure Facility (LDEF) exposed materials. In each set of samples, silicones were the major contributors to the molecular film accumulated on the LDEF exposed surfaces. All surfaces analyzed have been contaminated with Si, 0, and C; most have low levels (l atom%) of N, S, and F. The contaminant overlayer is thought to be patchy, with significant areas covered by less than 100 A...

The atmosphere can have a tremendous impact on tactical high-energy laser (HEL) systems. The variable nature of the atmosphere can produce highly variable performance. System designers need accurate environmental models to optimize the design of these systems. This paper reviews the atmospheric impact of various atmospheric phenomena on laser performance and the measurement and modeling efforts of the Air Force Research Laboratory. Two of these phenomena, optical turbulence and cloud...

Collisional relaxation of the atmospherically important free radicals OH and NO by open-shell atoms have been studied in a coordinated theoretical and experimental investigation. A quantum statistical method has been employed to describe collisional processes proceeding through a strongly bound collision complex, such as occur in the interaction of many free radicals with atoms. This theory has been used to compute rotationally and vibrationally inelastic collision rates for collisions of OH...

Expert knowledge suggests that the performance of automated infrasound event association and source location algorithms could be greatly improved by the ability to continually update station travel-time curves to properly account for the hourly daily, and seasonal changes of the atmospheric state. With the goal of reducing false alarm rates and improving network detection capability we endeavor to develop, validate, and integrate this capability into infrasound processing operations at the...

During the past twenty years, since Vincent Schaefer and Bernart Vonnegut demonstrated that clouds could be modified by the introduction of artificial freezing nuclei, there have been massive assumptions and impressive voids in our knowledge of plume patterns associated with silver iodide dispensed from aircraft and ground based sources. These assumptions have probably contributed more to the erratic project results and apparent failures of some field programs than any other single source of...

The Tropospheric Electromagnetic Parabolic Equation Routine (TEMPER) being developed by the Fleet Systems at the Applied Physics Laboratory has proven to be a useful tool in predicting low-altitude radar propagation. A marching procedure is used to step the field through what has been assumed to be a deterministic spatially varying index of refraction profile. In an actual environment, small-scale random fluctuations from atmospheric turbulence are superimposed on the deterministic profile. In...

The High Frequency (HF) radio band, commonly taken to be that portion of the electromagnetic spectrum lying between approximately 3 MHz and 30 MHz, remains a popular and often cost-effective alternative to communications satellites and terrestrial microwave links for low data rate signals such as teletype, and at sea or in underdeveloped areas. HF radio wave propagation is governed by reasonably well-understood, but not fully predictable, atmospheric phenomena. Determining the location of an HF...

A theory is presented to describe the advance of ionizing potential waves in preionized gases in nonuniform fields. The theory is based on the use of similarity and related arguments to bypass complicated mathematics and derive scaling relationships for wave speed as a function of applied potential and degree of ionization. For uniform preionization wave speed is predicted to scale linearly with applied potential and weaker than linearly with degree of preionization. These predictions are shown...
