Viscosity and low temperature lubricant characteristics determine turbine engine starting capability, and lubricant motion with respect to the contact surfaces at low ambient temperature. Such low ambient temperatures influence the oil viscosity and also the variation of its curve shape versus the temperature. According to the aforementioned research method, the requirements for accuracy and rel ...

We propose real time, compact hardware implementation and integration of sensors, algorithms, and processing hardware for extracting 3-D imagery and absolute range from visible and/or infrared (IR) images collected from small UAVs or situational awareness sensors. The proposed approach can be used for 3D structure reconstruction, scene interpretation, and 3D visualization. Sensor/ system will use ...

The primary objective of the proposed work is to develop a directed energy system analysis and design environment. This analysis and design environment will be based upon Distributed Heterogeneous Simulation (DHS) and Distributed Heterogeneous Optimization (DHO) technology. DHS allows the interconnection of models developed in different simulation languages running on different computing platfor ...

The primary objective of the proposed work is to investigate design techniques to improve torque density, power density, and efficiency in wound-rotor synchronous machines. The underlying principle of the proposed design technique is to alter the flux paths in the machine to increase torque production. This will be achieved through optimally altering the stator tooth geometry, rotor tooth geomet ...

SHOT’s innovative design for a deeply buried hardened target fuze incorporates the use of a non-inertial proximity sensor as a solution to the shortcomings of existing accelerometer –based smart fuze designs. The proposed sensor is compact, relatively low power, and can easily be adapted to a wide variety of proximity sensing problems in retrofit adaptable form factors. SHOT’s proposed desi ...

Specifically, the project advances high energy density cells by focusing on increasing the energy density of these cells. Our hi ...

The proposed Phase II program will optimize the design and manufacturing process of a compliant brush shroud casing. Recent tests at Wright Laboratories with staged brush seals have demonstrated significantly increased blade to shroud rub tolerance of acompliant casing. Phase I of the program is expected to demonstrate the feasibility of two innovative brush shroud designs with lower cost and we ...

During aircraft turbine engine operation, augmentor (afterburner) operation is often associated with combustion instabilities (oscillations) that can be potentially detrimental to the turbine engine if the resonant amplitude levels are excessive.Oscillation in the frequency range of 50-100 Hz is commonly called

The Phase I efforts aimed at establishing the feasibility of Air Film Damping for controlling vibration induced high-cycle fatigue (HCF) in gas turbine engine components. To establish this goal, current commercially available finite element software wasutilized to develop a methodology for predicting the effects of Air Film Damping on dynamic response of simple components such as beams and plates ...
