Dynamic Powder Consolidation for Full Density and Nano Grain Preservation

Phase 1 SBIR

Agency: Army
Topic: A11-088
Budget: 10/24/11 - 04/24/12
PI: Dr. Bhanumathi Chelluri

Transparent polycrystalline ceramic nanomaterials benefit a host of military applications including as laser materials, transparent armor, and high strength windows. While current nanopowder processing techniques produce large quantities of quality ceramic nanopowders, they yield parts with sub-micron to micron grain sizes when manufactured by c...

Flexible Cooled Power Conductors for Electromagnetic Railguns

Phase 1 SBIR

Agency: Navy
Topic: N111-074
Budget: 05/09/11 - 03/09/12
PI: Mr. David P. Bauer

Electromagnetic railguns are transitioning from single shot lab guns to a weapon system firing 6-12 rounds per minute. The cables that supply the railgun current from the power supply must also make this transition. We propose to develop a flexible coaxial cable with cooled conductors to meet this need. The cable system will be designed to deliv...

Compact High-Speed Isolation Device for MVDC Applications

Phase 1 SBIR

Agency: Navy
Topic: N103-226
Budget: 03/09/11 - 09/09/11
PI: Mr. Antonios Challita

Future ships will have significantly increased power demands compared to ships of similar size constructed today. To enable this, MVDC will be needed to move generated power to both propulsion and advanced weapons and sensors. Integrating large power sources and loads via a common DC bus simplified the interface control and hardware requirements...

Improved Electrical Contact Materials for Extremely High Current Sliding Contact Materials

Phase 2 SBIR

Agency: Navy
Topic: N091-069
Budget: 06/25/10 - 12/24/11
PI: Mr. David P. Bauer

Our Phase II objective is to scale-up the advanced armature materials developed in Phase I to large bore railguns, with bore sizes as large as 120 mm and lengths up to 10 m. This will be accomplished through a proven methodology of Integrated Launch Package (ILP) development at IAP. During the baseline Phase II effort we will develop the process...

Advanced Rail Materials for Electromagnetic Launchers

Phase 1 SBIR

Agency: Navy
Topic: N101-086
Budget: 05/10/10 - 03/09/11
PI: Mr. David P. Bauer

Erosion of copper rail surfaces in EM launchers is a major impediment to their development. Subscale testing at IAP has shown that thin high temperature bore layers such as Tantalum and other refractory metals offer significant protection against erosion. The focus of this Phase I effort is to establish the feasibility of using laser cladding an...

Improved Electrical Contact Materials for Extremely High Current Sliding Contact Materials

Phase 1 SBIR

Agency: Navy
Topic: N091-069
Budget: 05/18/09 - 05/23/10
PI: Dr. Bhanumathi Chelluri

For Naval railgun technology to be a reality launch package armature mass and armature induced rail wear must be significantly reduced. Lighter materials with enhanced electro-thermal properties and mechanical properties equivalent to current aluminum alloys are required. IAP is proposing the development of a powder metal (P/M) magnesium armatur...

Bore Insulator Protection Layer for a Naval Electromagnetic Launcher

Phase 1 SBIR

Agency: Navy
Topic: N08-074
Budget: 05/12/08 - 03/11/09
PI: Mr. David P. Bauer

This project will develop several bore insulator surface concepts to overcome the limitations found in current insulator designs. Prototype insulators will be built and validated through railgun testing in Phase I.

Bulk Nano Structured Thermoelectric Materials for Building Air Conditioning and Commercial Refrigeration Applications

Phase 1 SBIR

Agency: Department of Energy
Topic: 2008
Budget: 01/01/08 - 12/31/08
PI: Dr. Bhanumathi Chelluri

High-efficiency, bulk nano-structured thermoelectric composite materials with high performance (ZT ~ 3 or 4) are needed for refrigeration applications in buildings. The concept of improving ZT by making nano-structured thin film materials in the form of quantum wells and dots has been demonstrated. Instead, in this project, nano-structured bulk ...

Lightweight Transformer Replacement

Phase 2 SBIR

Agency: Office of the Secretary of Defense
Topic: OSD04-EP5
Budget: 04/26/07 - 04/26/09
PI: Mr. Antonios Challita

The overall objective of the Phase I effort was to establish the feasibility of a Solid State Lightweight Transformer (SSLT) Concept to significantly increase power density for 13.8 kV 2.7 MVA class transformers. This was accomplished by developing a concept for the Solid State Lightweight Transformer (SSLT) System which consists of the follow...

Investigate and Develop an Analytical Approach to Automatically Mitigate Electrical Faults Caused by Battle Damage

Phase 1 SBIR

Agency: Navy
Topic: N06-174
Budget: 03/21/07 - 09/30/07
PI: Mr. Antonios Challita

Electrical faults in the shipboard power system can result in the loss of power to critical loads of the system because today s electrical systems protection devices cannot clear faults in less than a cycle or two. The result is that very high current flow in the system. In this Phase I SBIR, we propose to develop an initial concept to limit t...
