 | An AH-64D/Unmanned Aerial System (UAS) aircrew workload assessment was conducted during February 2008 in Huntsville, AL. The purpose of the assessment was to evaluate AH-64D aircrew workload during UAS level II interoperability under simulated mission conditions. The workload assessment consisted of operational missions conducted by aircrews (eight pilots) in an AH-64D simulator. Pilot workload, situational awareness (SA), crew coordination, crewstation interface, switch actuations, simulator sickness, visual gaze and dwell times ... |

|
| In 2005, the U.S. Army debuted the TH-67 Creek flight motion simulator (FMS). Comments from the first class to use the devices indicated an unusually high number of instructor pilots (IPs) and student pilots (SPs) experienced severe simulator sickness (SS). To investigate the potential problem, a pre-study was conducted using the Simulator Sickness Questionnaire (SSQ) to collect data from three, 5-day class cycles from 73 IPs and 129 SPs. Based ... |

|
| The effects of increasing ion-neutral collisions on velocity-shear- driven ion cyclotron waves have been studied in simulated ionospheric conditions in the Naval Research Laboratory's Space Physics Simulation Chamber. The experiments show that shear-driven ion cyclotron waves can exist for ion-neutral collision frequencies of the order of the ion gyrofrequency. For higher collision frequencies where the ions become unmagnetized, a transition to a higher frequency mode is observed. |

| A cold electron beam, propagating through a weakly ionized plasma will, under proper conditions, produce a modified beam-plasma state known as the Beam-Plasma-Discharge (BDP). As the subject of a continuing series of experiments in a large facility chamber it was previously determined that the BPD had an abrupt ignition threshold as the beam current I sub B was increased at fixed beam energy. While a specific empirical relationship was established ... |

| An infrared optical transmission chamber was developed to measure the spectral transmission of cryogenically cooled (20 K and 80 K) optical windows, filters, etc., both with and without cryodeposit contamination. An FTS-14 Interferometer Spectrometer recorded transmission measurements for 20 and 80 K germanium windows both clean and with the following contaminants condensed on them: NH3, CO2, CO, CH4, HC1, and air. These measurements were made for many different contaminant thicknesses. ... |

| Volatile condensable material (VCM) measurements on a number of spacecraft materials have indicated that contamination rates onto surfaces at subambient temperatures cannot be predicted from standard outgassing tests, particularly where long-term exposures are involved. Contamination rates may depend markedly on temperature differentials between source and collector, the collection temperature, the source geometry and the exposure time. Contamination rates may also be influenced by solar irradiation. The results of this study ... |

| At the present time, duplication of reentry environments in ground test facilities cannot be satisfactorily accomplished. Major deficiencies in such facilities are: too short test times, gases not representative of the atmosphere because of residual dissociation and ionization of air molecules, and stagnation pressure and enthalpy not representative of those produced through dynamics of the flight vehicle. Many new concepts and attempts to circumvent these limitations have been studied over ... |

| A careful study of the reflectances of carbon dioxide and water cryodeposits was made in a vacuum integrating sphere in the solar wavelength range (0.30 to 2.55 micrometers). These deposits were formed on liquid-nitrogen-colled black epoxy paint and polished stainless steel substrates. The reflectances of these deposits were studied while varying the deposit thickness, view angle, and wavelength. The reflectance dependence on thickness was also predicted theoretically and the values ... |

In creating a realistic mathematical model, six different sets of boundary conditions are employed in order to determine which most closely approximates the actual experimental results. The medium is considered to be absorbing and scattering; due to the cryogenic temperatures involved, emission is justifiably neglected. The scattering is considered as isotropic.
