Miller Fasteners made from 2-D laminates represent the state of the art in joining CMC panels to metal frames. Despite its success, the extant Miller fastener design is limited by its construction from a laminate of 2-D fabric. The resultant fastener part has poor interlaminar shear strength, and its manufacture and application entails high machining costs and high material scrap rates. 3TEX, i ...

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 computational system is required that contains validated/certified tools and models that can be readily employed by non-FEM experts. Designers would be able to input parameters, such as panel bay spacing, boundary conditions, skin material and thickness, skin stiffness, flushness requirement, and scarf angles, while the system would automatically construct a valid finite element representation ...

The proposal outlines the use of rapid protyping techniques to create a functional small scale feasibility system and documentation to provide a demonstration of the features needed in a full-scale automated isolation and tag-out system. It will use a highly innovative, patented network control technology that provides a reliable, low cost means to interconnect thousands of remote sensor and cont ...

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, ...

The USN is seeking innovative solutions to model and aid in the prediction of enemy course of action with emphasis on learning, adaptation, and intent. While analysts and strategists are well-versed in tracking threats against conventional military targets, the new asymmetric threats posed by insurgents and terrorist organizations alike, are much more difficult to anticipate. Given the events and ...

We propose investigating new technology for cutting fishing nets, both for commercial fishing or that may be deployed for UUV denial purposes. The envisioned technology is conformal and modular, intended initially for the MRUUV but scalable to larger and smaller vehicles. It is intended as an affordable system requiring minimal space and energy, while providing redundancy in capabilities through ...

Utilizing Nitronex’s solid state GaN FETs and SAIC’s design expertise in PAs, a small, lightweight power amplifier can be achieved. Specifically, in this phase I effort, Nitronex will advance GaN technology and design high power (>250W) devices with very low thermal resistance in order to provide building blocks required for the PA. Nitronex will perform extensive thermal simulations and arr ...

Nitronex will use baseline GaN HEMT process (NRF1) to demonstrate feasibility of broadband 35-40W solid-state PA with >35% efficiency across 225-3200MHz frequency range required by the program. Nitronex will establish feasibility by (a) reducing thermal resistance of current generation device layout through thermal simulation (b) modifying CFET model with updated thermal characteristics of the ou ...

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 ...
