Advances in both software and computer hardware have made the finite element method the preeminent choice for analyzing highly complex systems that are of great value to the Department of Defense.   The US Defense industry, however, continues to spend enormous time and resources in mesh generation, a key step in finite element analysis, despite progress that has been made in automated mesh gener ...

The objective of our proposed STTR phase-I work is to transition the latest advancements within the academic community to the design of a robust, user-friendly, and application-oriented tool for automatic hex-dominant meshing. Our software will fully couple CAD models to the discretized domain required by finite element software in structural analysis and other simulation and modeling applications ...

In the proposed STTR study, Catto Propellers, Inc. (Catto) and the University of North Dakota (UND) will create an efficient new propeller design utilizing advanced composite materials for use on small unmanned x systems.  During Phase I, a comprehensive study will be conducted to develop a new propeller design in order to increase propeller efficiency, reduce aerodynamic noise and utilize innova ...

Towing of a Magnetic Anomaly Detection (MAD) system is an important aspect of rotorcraft maritime operation in support of Anti-Submarine Warfare (ASW). The vibratory rotary wing platform combined with the long and flexible towing cable, the low mass ratio of the towed body to the total mass (the sum of the tow body and the towing aircraft), and the rotor downwash impingement on the towed body duri ...

Towing of a Magnetic Anomaly Detection (MAD) system is an important aspect of rotorcraftmaritime operation. The oscillatory rotorcraft combined with the long and flexible towingcable, the low mass ratio of the towed body to the towing aircraft, and the rotor wake effecton the towed body presents a challenge for integration of a modern MAD system withrotorcraft platform. The research objective is t ...

In our Phase I program, JEM and ASU will demonstrate a low cost manufacturing process to achieve the full theoretical hesitivity of a magnetic film that would enable greater effective hesitivity laminate. In Phase II we will develop a viable continuous process for two such materials to achieve light weight, low cost, and improved radiation efficiency; and we will seek to productize this process to ...

The Navy is interested in developing hybrid superconducting power transmission cables that would carry at least 5 kA of current and have a current density of at least 35 MA/m2. The cable should be able to carry 30 % of the rated current even when the superconducting cable fails. We propose to develop a hybrid superconducting cable, based on CORC cables, which potentially have a current density of ...

The Navy seeks new energetic and oxidizing ingredients for use in propellant and explosive formulations of modern weapons systems. With recent developments in the design and synthesis of new energetic molecules, we have the opportunity to take the steps needed before these materials can successfully transition to use in next generation propulsion and ordnance systems. TDA Research and the Universi ...

We propose development of a software capability which, based on use of MathSysaccurate and efficient exact-physics computational electromagnetics (CEM) solvers, will enable modeling and optimization of the properties of on-platform pRFID tag/reader antenna systems. Passive Radio Frequency Identification devices (pRFID) mounted on complex rotorcrafts pose challenging modeling problems: since pRFID ...

Additive manufacturing (AM) is a very promising technique for rapid, low-cost production of aircraft parts directly from a CAD file. AM is especially appealing for complex parts that would be costly or impossible to fabricate by machining or casting. At the current time there are no reliable, cost-effective techniques to qualify the finished parts. Several government studies have noted this gap an ...
