The objective of this project is to develop and validate a CAD tool for the rapid design of mechanically fastened repairs, bonded repairs, and hybrid repairs involving both adhesive bonding and mechanical fasteners. To allow use by non-specialists, the CAD tool will replace the current process of manual construction of joint finite element models with CAD tinker toy assembly using parametric par ...

A simple clamping U bracket to secure itself under pressure on both sides of the aircraft's structural frame ribs. A clamp will be placed on every section where the bonded studs currently exist. A cavity on the bottom of each clamp will hold a stud or other tool to secure the blankets. The outer surface of the bracket will be made of rubber and the inner core will be made of 9255 spring steel, ...

Information Management is an important component in the development of viable information sharing systems, such as JBI, where shared information may be manipulated to derive further information. The qualities of such derived information depend on qualities of the contributing information and of their sources. Determining information quality requires propagation of qualitative and pedigree data abo ...

The military is actively implementing diagnostics, prognostics, and health management technologies across platforms in an effort to reduce maintenance costs, increase readiness and availability, and improve safety. In aircraft electric power systems, the largest maintenance driver is the generator, followed by the batteries. Common faults include winding shorts, pitting and spalling in bearings, a ...

Preservation of the perishable food, especially fresh fruits and vegetables (FF&V), is particularly challenging due to substantial amount of refrigeration required to prevent spoilage. In the case of FF&V, the refrigerated air can quickly become contaminated with ethylene gas produced by the fruits and vegetables, which can lead to autocatalytic ripening of FF&V and accelerate spoilage even at id ...

The goal of this research is to produce a light-weight, inexpensive bioluminescence sensor capable of accurately measuring fine-scale vertical bioluminescence potential (

This is a proposal to research new methods of coating small particles using a water-based electroplating process. These methods would build upon existing technology, in which small particulates are placed into a metallic-ion-containing electrolyte solution inside an electroplating device. The particulates are repeatedly stirred, allowing sedimentation to occur by gravity until a sedimentation laye ...

A system that provides a large field of regard for propagation of a lethal beam from a transonic platform will be evaluated. The proposed design incorporates concepts to address the fact that shocks do develop in transonic flow, but with the proposed system the field of regard should be enhanced. A second feature is provided that allows a simple method of controlling optical aberrations imposed b ...

The F-35 prognostic health management (PHM) system will generate a large volume of data on current and predicted component health. Tools are needed to automatically assimilate and analyze this data, and present findings and recommended actions to the user. These automated reasoner tools are necessary to ensure that PHM data is utilized for maximum benefit, to allow maintainers to focus on maintena ...

We propose to design and implement a domain-specific language (DSL) called Nettle that will eliminate a large class of network misconfiguration errors, together with a verification tool that will be used to establish the correctness of other network configuration specifications. Advantages of our approach include: - It can be deployed gracefully and incrementally. The use of Nettle will guarantee ...
