In this STTR, Daniel H. Wagner Associates, together with the University of Michigan (UM), will develop a Detection Avoidance System for Submarines (DASS). The proposed DASS is a set of software modules which solves the probabilistic passive sonar equation (PSE) using given environmental acoustic data, assesses submarine vulnerability based on intelligence about potential threat ASW assets, recomme ...

SI2 Technologies, Inc. (SI2) proposes to accelerate development of printed, high-efficiency phased arrays operating at Navy-relevant frequencies. The proposed development effort will include optimization of the array printing techniques from Phase I to meet the Navys phased array performance goals. The printed arrays will incorporate both printed radiating elements and an innovative printed packag ...

Rechargeable lithium ion battery systems can provide power throughout the aircraft, including engine or Auxiliary Power Unit (APU) starting, avionics, emergency, and other systems. Because of their high specific energy/power and potential thermal instability, they can present hazards if improperly designed, tested, handled, or stored. To address the thermal safety issue of Li-ion batteries, EIC La ...

Corrosive environments together with cyclic loading can lead to the formation of localized corrosion pits and corrosion fatigue cracks which can significantly deteriorate the structural integrity of aircraft components. The exact nature of corrosion fatigue damage is dependent on the competing multi-scale processes resulting from complex interactions between the structural material, its environmen ...

The U.S. Navy is seeking new technologies and platforms to advance airborne anti-submarine warfare (ASW) and related maritime surveillance. Current magnetic anomaly detection (MAD) sensors, such as the latest versions of atomic magnetometers, are capable of very low noise operation. However, the performance of these sensors can be limited by the geomagnetic noise environment more so than by eithe ...

The Navy faces a significant challenge to its dominance of sea and air given the Anti-Access Area-Denial (A2AD) capabilities of major powers. The Navy's response, in part, is to implement technical capabilities that enable platforms to coordinate in new ways to execute offensive and defensive actions at very long range. While the Navy finalizes this Naval Integrated Fire Control-Counter Air (NIFC- ...

Agiltron in collaboration with National Renewable Energy Laboratory (NREL) will develop a new class of high-efficiency and lightweight broadband inverted metamorphic multi-junction (IMM) solar cells for the uninterrupted flight missions of unmanned aerial vehicles (UAVs). The approach is closely coupled with Agiltrons extensive experience in high-transmittance broadband and wide-angle anti-reflect ...

The specific research objectives of this program are to develop a rugged and human equivalent (human-sized, multi-fingered with opposing thumb) underwater robotic hand that mimics the dexterity of a gloved diver and that can replace existing 1-DOF pliers on Navy Atmospheric Diving Suits (ADS) and Navy UUV (Unmanned Underwater Vehicles) without any mechanical seals. Furthermore it is the objective ...

It is critical to the safe use of ceramic matrix composite components that information on the fracture toughness of these materials be available in order to allow an assessment of the likelihood for crack growth. Although Military Standards and American Society for Testing and Materials both serve as resources for room and elevated temperature test methods, there are no standards to obtain the int ...

Widely used composite materials reduce aircraft weight and cost, improve structural performance, and boost fuel efficiency. However, composites are susceptible to adhesive bond line quality issues, both in initial fabrication and in service related bonding failures. Detection of weakened bonds requires an easy diagnostic approach to routinely monitor composite aircraft health. Our proposed solutio ...
