Lynntech is developing a single-loop hydraulic line clamp cushion that meets or exceeds Navy reliability requirements resulting in fewer maintenance cycles, lower costs, and increased operational readiness. Clamp materials, derived from UV and ozone resistant polymers, have demonstrated pass performance after hydraulic fluid immersion, fuel immersion, heat aging under standardized test conditions, and continue to pass specifications after exposure to accelerated degradation conditions (equivalent to >66,000 hours of UV and ~18,000 hours of ozone exposure at 50,000 ft). Lynntech’s multidisciplinary staff has a 33 year history of developing and transitioning technologies to make a warfighter’s job safer or better. These advanced clamps can be applied to any airframe and will be provided to NAVSUP and OEM manufacturers.
Lynntech’s Computer Vision FoolKit realizes a form of camouflage tailor-made for making an object of interest evasive in appearance to computer vision systems. This technology exploits computer vision classifiers by manipulating the input signal - so called adversarial examples. Lynntech’s multidisciplinary staff develops and transitions technologies to make a warfighter’s job safer or better. This innovative computer vision camouflage significantly disrupts the performance of cutting-edge ISR/ATR systems. Lynntech has successfully fooled white box (known) classifiers and has developed rigorous synthesis and evaluation procedures to ensure the effectiveness of our camouflage patterns in black box tests against unknown classifiers. Lynntech intends to work with US Marine Corps PEO Land Systems and other customers to develop computer vision camouflage capabilities to meet their operational needs.
Lynntech is developing practical all solid-state (PASS) batteries with enhanced safety and performance for military aircraft and other applications. Lynntech has significant experience developing advanced batteries. for military and commercial applications. PASS batteries utilize core-shell electrodes and high conductivity solid electrolytes. These features provide a clear competitive advantage over current Lithium batteries based on improved safety/abuse tolerance and cycle life, in addition to high energy and power densities. The F/A-18 & EA-18G Program Office (PMA-265) is an initial transition target as the sponsoring program office, while Air Anti-Submarine Warfare Systems Program Office (PMA-264) has shown interest to support efforts by the Electrical Power branch within NAWCAD to begin an assessment for the potential for a post-Phase II initiative. Lynntech has performed both lab-scale and scaled-up electrode/electrolyte preparations, including cell fabrication and evaluation, which demonstrated the capability of PASS batteries to meet the Navy’s requirements.
Early detection of lithium battery faults provides critical warning before these issues evolve into more hazardous situations, such as fire, toxic off-gassing, or catastrophic failure. Lynntech is developing an early warning fault indication system (EWFIS) with low volume, weight, and energy. It provides high speed monitoring at the cell level along with system performance monitoring, triggering an alarm when a battery fault precursor is detected. Lynntech has significant experience in developing lithium batteries, miniature chemical sensors, and integrated electronics. EWFIS can be adapted to many battery packages and chemistries, including Li-ion batteries in Navy’s UUVs and submarines. EWFIS prototypes have been successfully designed, fabricated, and tested for monitoring Li-ion batteries (8 or 32 cells). The ultimate transition goal for this technology is government and prime contractor systems for monitoring lithium batteries, increasing safety and reliability.
The Navy utilizes polymer-bound energetic materials for warheads, propellants, and pyrotechnics. Properties like mechanical strength, pot-life, processing, and cure times are either key features or challenging impediments. Advances in additive manufacturing utilizing diverse materials can be leveraged to perform formulation testing and rapid prototyping of unique energetic formulations. This enables potential fast-tracked scale-up processes for the direct manufacture of warheads, propellants, and pyrotechnics. Lynntech has experience developing novel feedstocks for additive manufacturing and working with energetics; we are developing photo-curable and multi-stage cured polymer/binder systems for COTS 3D printer rapid prototyping (print, cure, and testing) of explosive formulations. These unique 3D printable feedstocks can be integrated into development and manufacturing processes utilized by government and prime contractors for testing and production of energetics.
Lynntech Inc is developing new polymeric materials that can be extruded to make filaments compatible with fused filament fabrication (FFF) techniques. The newly developed polymer formulations, textile design, and printing process will reduce the number of steps required to manufacture clothing items and simplify production of personalized garments. It will also allow production of clothing articles with mechanical strength and water vapor transport capabilities essential for military fabrics, and allow low volume manufacturing of garments in remote locations. Moreover, this technology will allow for design of garments from a 3D body scanner. Lynntech, a 2016 Tibbetts award winning small business, is looking for textile partners to integrate our 3D printing techniques and formulations into their customizable clothing article development.
Lynntech Inc. has developed On-Demand Hypoxia Trainer (ODHT) – a portable, pressure-on-demand, mask-on, train-like-you-fly, hypoxia training device for aircrew. The ODHT is based on an energy-efficient electrochemical oxygen pump and has successfully undergone human effects testing at Embry Riddle Aeronautical University. Production of the ODHT starts in 2019. The initial customer is the Navy Medicine Operational Training Center, Naval Survival Training Institute; units are scheduled for delivery to NAVAIR starting in late FY 2019. Lynntech, a 30-year old small business successful at developing and transitioning electrochemical-based technologies to the warfighter and 2016 Tibbets Award winner, will manufacture the ODHT in-house and supply it to the customer.
Lynntech Inc is developing rechargeable lithium-air batteries composed of a lithium metal anode, a lithium-ion conducting electrolyte, and a porous air cathode to meet the increased energy demands of military aircraft and systems. Lynntech has significant experience in developing advanced electrodes and electrolytes for lithium-based batteries. The Airborne Electronic Attack (AEA) Systems and EA-6B Program Office (PMA-234) is the acquisition program sponsor under Program Executive Officer for Tactical Aircraft Programs [PEO(T)]. Rechargeable lithium-air batteries provide greater specific energy, wider operating temperature ranges, longer lifetimes, enhanced safety, and lower cost than current lithium-ion batteries. Phase I results have demonstrated the feasibility of rechargeable lithium-air batteries with high specific energy, enhanced safety, and wide operating temperature performance that meet the Navy’s requirements for naval aircraft power systems.
Hypoxia training is essential for early recognition of hypoxic conditions which is paramount for corrective actions to minimize the adverse impact on pilots. Existing hypoxia training devices are bulky, have significant logistic demands and are susceptible to air starvation of the trainees. Lynntech is developing a compact, portable, pressure-on-demand hypoxia training device that allows the mobility to support training anywhere, eliminates the risk of oxygen starvation that the current equipment suffers from, and has a pure oxygen delivery feature that decreases recovery time. The device is predicated on an electrochemical oxygen separation technology, is very efficient, and is operated on a standard 110VAC wall outlet. Lynntech’s hypoxia training technology will increase the quality, efficiency, flexibility, and safety of hypoxia training for the Navy and others.
