Mobile radios on highly dynamic platforms, when networked into a virtual antenna array, can perform distributed array agile beamforming (DAAB) to serve the purposes of communications at longer range, higher data rate, and higher quality of service, targeting (an imaging radar for intelligence surveillance and reconnaissance - ISR) at longer range and higher resolution, and more powerful electronic ...

Acceleration of a launch package from a railgun is a disruptive technology with capabilities to launch projectiles in a shorter time-to-target and a greater effectiveness at long range. However, these railguns generate tremendous magnetic fields of up to 20 Telsa. These magnetic fields pose a threat to on-board, mission-critical electronics within the launch package. Mainstream Engineering Corpora ...

The goal of this proposal is to develop PFC hardware that can interface with combat aircraft 115V, 400 Hz, power systems and provide system reactive current to correct the 0.98 leading power factor to 0.93-0.97 lagging. To this end, Mainstream Engineering proposes a configurable inductor that can provide up to reactive current to the aircraft 65 kVA power system. The proposed PFC hardware will be ...

The toolset Anyar will develop in this SBIR will provide a 3D physics-based engine for assessing the effects of single and/or multi-weapon engagements against maritime geometric target models. Many of the algorithms/methodologies for the physics-based calculations involved in maritime engagements already exist and have been developed by contractors and government agencies; however, they tend to be ...

Experience in utilization of test information standards exposes levels of allowable variance that circumvents interoperability and allows proliferation of incompatible products. The standards must provide this flexibility in order to accommodate the variety of applications for which they are intended. However, achievement of compatibility, interoperability and other objectives associated with the ...

The MJU-49/B decoy is an infrared countermeasure dispensed by the ALE-47 countermeasure defense system to protect Navy aircraft form incoming threats that utilize infrared sensors. This decoy uses pyrophoric foils that react with atmospheric air upon release to give an infrared signature whose emissions are tailored to the threat sensors. The Navy has identified that greater protection would be af ...

Whether a laser-based system is used to autonomously detect and recognize a periscope, or the laser-based system is used as a complement to a radar-based periscope detection system, the timeliness of the laser-based detection is critical. Electronically steering the pointing direction of the laser and the field of view of the laser receiver enables a timely response by the laser-based system to an ...

For this research program, Mainstream will develop a nanocomposite thermal interface material (TIM) combining the benefits of boron nitride nanotubes (BNNTs) and cellulose nanofiber (CNF) for use with Navy-relevant power conversion components. The overall goal of the SBIR program is to develop a usable product with the following characteristics: robust to vibration and abrasion, non-permanent bond ...

Optical cooling is a unique and promising cooling method capable of cooling to cryogenic temperatures in the absence of moving parts, noise, or vibration. Only a laser is used to pump in light; a semiconducting material upconverts this energy to reject higher energy photons producing a net cooling effect. Optical cooling is contrasted by mechanical systems, such as Stirling cryocoolers which can b ...

The addition of CNTs traditional steel cabling has the potential to significantly improve cable strength and longevity. However, previous methods for CNT integration struggle due to CNT aggregation and poor interfacial interactions between CNT and matrix. Mainstream’s CNT coating process is based on a simple, scalable, one-pot process that uses emulsion chemistry to coat a metal on the surface o ...
