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

Modern turbine engines undergo extensive ground testing in test cells during development. These engines are instrumented with numerous strain gages for high-frequency dynamic strain measurements. Currently, analog signals from these gages are routed out of the test cell to remote data acquisition equipment over hundreds of feet of wire. With up to 200 gages to be installed, the task of patching ...

The Air Force is in need of a system to measure stray laser energy during the open-air test-range firing of high-energy laser weapons such as the Airborne Laser. In Phase I, a laboratory-scale system composed of four hemispherical-imaging laser-scattering detectors was constructed to monitor light scattered from stray laser energy during simulated laser weapon engagements. It was demonstrated th ...

Current survivability and engineering requirements for airframe platforms necessitate the automated application of numerous specialty coatings onto critical surfaces. One such critical surface is an airframes inlet duct OML surface. These specialty coatings have tight specification tolerances for the final thicknesses and surface finish. Sanding is required to meet the final thickness and surfa ...

The objective of this proposal is to identify and integrate multi-echelon constraints in Manufacturing Repair Overhaul (MRO) process planning and scheduling. The OC-ALC depot operates in a multi-echelon MRO environment that is highly constrained regarding its capacities, resources, deadlines, and other physical limitations. The representation, capture, satisfaction and relaxation of these constra ...

The main goal of this work is to develop a more reliable, robust, and accurate measurements of radome transmission properties. As a result, we propose a pilot study in order to design a two-horn testing system and provide several prototype radome testing measurements. The proposed two-horn testing system will be mainly focused on transmission efficiency mechanism. The proposed system features a ...

Due to the significant decrease of aircraft parts across the U.S. military over past years, managing parts more efficiently has become a great necessity. The term managing suggests having the data resources available to predict, forecast events or determine an item’s use such as the mission capability of a part or weapon system. The decrease of parts can be attributed to many factors, some of w ...

The objective of this proposal is to develop a low cost head tracking system to monitor the orientations of an individual’s head. This head tracker can be incorporated with a 3-D audio system that will provide cues to operators for increasing situational awareness. This proposed system will be based on Archangel’s Inertial Measurement Unit ‘IM3’. The Head Alignment and Orientation (HALO) ...

The Security to the Edge strategy identifies a growth area in the development technologies to enable Trusting the Edge; particularly, two research areas are specified: i) hardening an edge node against physical attack; and ii) facilitating the ability of an edge node to monitor and communicate the state of its integrity. The thrust of this proposal is twofold: i) to describe a technique for hidin ...

The AEDC Engine Test Facility (ETF) has more than 20 test cells that can be used for testing prototype propulsion systems and components. The testing of propulsion systems requires significant data acquisition capabilities, with one test utilizing more than 4200 channels of instrumentation, including 200 dynamic strain gages. In response to the shear set-up challenge, AEDC has developed the conc ...
