To provide power for unmanned aircraft systems (UAS), we propose developing solar cells made using perovskite halide solar absorbers, such as those based upon methylammonium lead iodide (CH3NH3PbI3). Our phase I efforts produced flexible solar cells that exhibited power conversion efficiencies (PCE) of 8.1%, a landmark achievement. The proposed research details how to achieve 20% power conversion ...

The Department of the Navy has a need for the development of an additive manufacturing (AM) process for key vacuum electronic device components to meet on-demand, flexible, and affordable manufacturing requirements. The goal of this Phase II effort is to develop and validate Electron Beam Melting (EBM) additive manufacturing (AM) technology for the production of vacuum electronic devices meeting t ...

CL-20 is the most powerful conventional explosive known, but its high cost has limited its adoption in a range of potential applications. Par of the challenge in making these materials is the complexity of the reaction used to prepare the polycyclic cage. The complexity of this reaction makes it difficult to have insight into the reaction and to improve it. Additionally, several of the intermediat ...

The Shallow Water and Surf Zone Minehunting program (MAD SWARM) is described that spans the development and demonstration of swarming micro-air vehicles (MAV’s) equipped with Magnetic Anomaly Detectors (MAD’s) to autonomously detect and locate mine targets in shallow water and the surf zone. The MAD Swarm system incorporates low cost micro-air vehicle (MAV) technology, swarming sensor search/c ...

In Naval, surface electronic warfare (EW), visual displays form critical bridges between warfighters and the complex operational radio-frequency (RF) spectrum they must monitor and interpret. Surface electronic warfare operators and supervisors must monitor and interact with multiple, stove-piped display systems in order to perform their work. Further, the visual displays they employ are not desig ...

The purpose of this Phase II project is to develop computational modeling methods that are able to describe the propagation and interaction of fatigue cracks using the phase-field methodology within the numerical framework of isogeometric analysis (IGA). The resulting computational platform, while focused on fracture and fatigue, will be general, in that any phase-field method can be easily incorp ...

We propose development of an improved bottom database suitable for use in the frequency range of 1-10 kHz. Measured transmission loss (TL) and reverberation level (RL) will be jointly processed in building the database. The influence of the rough sea surface, rough seafloor, as well as subbottom heterogeneity will be accounted for during database generation. The rough sea surface will be character ...

We propose to develop Cyber RAMPART as an extensible and customizable training delivery tool with near-term transition potential. It will offer shipboard operations personnel the opportunity to develop foundational cyber awareness knowledge and skill that prepares them to participate in their ship’s cyber defense mission and to hit the ground running in future fleet-level exercises that include ...

The introduction of new systems and technologies is critical for maintaining superiority, yet this brings with it uncertainty regarding the impact on users, teams, and organizations. Rigorous test and evaluation (T&E) practices are essential prior to acquiring and instituting new technologies, particularly to objectively assess the workload imposed on end users. Aptima, Inc. and its partners – S ...

Magnetic materials with high hesitivity values are needed to achieve low-profile conformal broadband magnetodielectric antennas with significantly enhanced efficiency in HF-UHF. The higher the hesitivity, the higher the attainable efficiency in these magnetodielectric antennas. State of the art hesitivity as high as 6×10^6 O/m has been reported in CoZrNb alloy films. Further hesitivity improvemen ...
