 | This report presents an analysis of the first three months of calorimeter data from the NAVSTAR vehicle 38 solar array contamination flight test. The conclusion of this preliminary analysis is that the calorimeters' solar absorptances are increasing at a rate of several percent (absolute value) per year. These values are consistent with the observed approx. 2% per year anomalous solar array power loss. ... |

| The DoD procurement account fell by more than 70% during the past decade. The cost associated with the next generation of rotorcraft design, analysis, testing, training, and support, using current techniques, promises to escalate in a predicted hostile fiscal environment. This cost must be reduced through the use of credible simulation and other analytical options. Conventional multi-service air vehicle flight testing is becoming more expensive and the test results may ... |

| During the Electric Propulsion Space Experiment (ESEX) mission, eight firings of the 26 kW ammonia arcjet were performed. Data from on-board systems, GPS, and radar ranging taken during these firings are used in this paper to determine thruster performance. The on-board Servo Accelerometer Assembly (SAA) measured spacecraft acceleration continually at 10 Hz. Although the design prohibited precise acceleration measurement in the range nominally expected during the firings, estimates of acceleration ... |

| Development of effective countermeasures for use against infrared (IR) missiles is hindered by the difficulty inherent in testing tactical missiles. The designers of such a countermeasure must devise a means of reproducing missile attitude after the test flight to allow for further analysis. This thesis describes an Inertial Measurement Unit (IMU) compact enough to be mounted on board a 4.5 inch missile. The IMU sensing elements are three quartz rate ... |

 | The contract for developing the interceptor was a cost-plus-fixed-fee contract, a contract type that placed all of the program's financial risk on the government and did not include provisions that could be used to hold the contractor accountable for less than optimum performance. Flight-test failures have been caused primarily by manufacturing defects rather than problems with advanced technology. These failures have prevented the Army from demonstrating that it can reliably ... |

| Helicopter/slung load systems are two body systems in which the slung load adds its rigid body dynamics, aerodynamics, and sling stretching dynamics to the helicopter. The slung load can degrade helicopter handling qualities and reduce the flight envelope of the helicopter. Confirmation of system stability parameters and envelope is desired, but flight test evaluation is time consuming and costly. A simulation model validated for handling quality assessments would significantly reduce ... |
