ABSTRACT: The need for evaluation of aerodynamic loads on internal weapons bay doors comes from the US Air Force's requirement to open doors on many of its aircraft during flight. This ranges from an aircraft's low-speed opening of landing gear doors and speed brakes to opening weapons bay doors in supersonic flight. This sets up a situation for unsteady aerodynamic loading of these surfaces due ...

ABSTRACT:We propose to develop and demonstrate component technologies, interfaces, and software necessary to build a prototype Short Wave Infrared (SWIR) projection system with high dynamic range and fast frame rates. More specifically, final hardware deliverables for this project include three (3) tested hybrid modules that integrate a 1024x1024 24-micron pitch SWIR LED emitter array with a match ...

ABSTRACT:Development and use of new composite materials is imperative for continued advancement of airframe and engine systems.In order to facilitate the accelerated insertion of new composite materials, there is a need for an improved analysis methodology that allows designers to reduce the time and cost associated with material and structural development and test programs.The goal of the propose ...

ABSTRACT: Composite materials often represent the most weight efficient and lowest cost solutions for airframe structures. Many of these structures are in areas that are susceptible to incidental impact damage and require adequate residual strength after impact for specified periods of service. Current design methodologies require designers to predict the residual response of full-scale composit ...

Passive microwave sensors aboard satellites provide valuable information regarding weather conditions by measuring atmospheric attenuation over a broad range of frequencies from 0-200 GHz. Additional ground-based sensors are desirable to provide complementary upward looking measurements that can be used to refine existing attenuation models. Operating over such a large bandwidth, however, places ...

ABSTRACT: Next generation liquid rocket systems, envision novel designs for cryogenic turbopumps that exhibit high suction performance with low inlet pressures, operate at high tip speeds to reduce size and weight, and can be throttled over a wide range of low, off-design flow conditions where the inlet flow quality is poor with large backflow. These are extremely demanding flow regimes which ma ...

ABSTRACT: The production of 3D models from aerial imagery has been an active research area for many years. Given sufficient image texture and a variety of divergent camera viewpoints, camera pose and scene structure are fully recoverable. Further, software for fully reconstructing a scene from an image set is now freely available. As the range of viewpoints decreases, however, traditional methods ...

Individual differences in vulnerability to sleep loss and fatigue from extended work hours and night work are a substantial problem in transportation policy making, work schedule development, fatigue risk management strategies, and prediction of performance impairment in real-world operations (Van Dongen et al. 2003; Mollicone et al. 2010). Our group was the first to document the considerable magn ...

ABSTRACT: The challenges in the operations of small unmanned aircraft systems (SUAS) and micro air vehicles (MAVs) in terms of required agility and benign flying qualities require a superior understanding of their basic flight mechanics and vehicle dynamics. Flight test data for MAVs are sparse, and wind tunnel unsteady aerodynamic data of MAVs with flexible wing structures are non-existent. Alth ...

ABSTRACT: TRS Technologies, Inc. proposes to develop nonlinear dielectric ceramic capacitors for discharge pulse power application and reduce the production cost of cofired multilayer capacitors. In the phase I program TRS developed a new antiferroelectric composition showing energy density>4J/cc at a field as low as 200kV/cm and demonstrated that high breakdown strength can be achieved from ant ...
