PacMar Technologies engineers are collaborating with the Office of Naval Research to develop hybrid and all-electric propulsion systems for Navy craft that maximize energy efficiency and reduce the vessel’s signatures, making them safer for the warfighter to operate in contested environments. Power & Energy Electric and hybrid-electric propulsion systems for small craft, amphibious vehicles, and unmanned aircraft is a new frontier for PacMar Technologies’ model and simulation, control systems, and power electronics. Innovative propulsion concepts rely on energy efficient platforms and harvesting concepts for general system electrification. Using advance power architecture and power management enables long-duration operations for a variety of military and commercial applications. Hybrid and All-Electric Propulsion Systems PacMar Technologies engineers are collaborating with the Office of Naval Research to develop hybrid and all-electric propulsion systems for Navy craft that maximize energy efficiency and reduce the vessel’s signatures, making them safer for the warfighter to operate in contested environments. PacMar Technologies is also performing research to advance the maturity of next-generation integrated power and energy systems (IPES) for Navy combatants that can adaptively route power from a ship’s propulsion system to meet the demands of directed energy weapons. Energy Harvesting PacMar Technologies is at the forefront of developing technology that can harvest energy from the ocean environment to power nearby installations or recharge unmanned vehicles, keeping them on station and performing their mission longer. Previous and ongoing work includes harvesting from the sun, waves, and ocean currents. Our capabilities in this area span system design, power takeoff mechanism design, energy feasibility analysis, and prototyping construction. Systems Engineering and Integration for Advanced Power Architectures The electrification of military vehicles is steadily increasing as more mission systems and payload require electrical power, energy efficiency, and resiliency. PacMar Technologies power systems and electrical engineering experts are collaborating with the Navy and Army to design new architectures for compact and resilient power systems with applications for integration. Power management controls for long-duration USV operations The Navy is on a path to acquiring medium and large unmanned surface vessels that are expected to operate in the open ocean for long periods. PacMar Technologies power systems researchers are tackling a core limitation of these USVs – how to maintain stable electrical power for 30 days or more without human intervention. Our experts are researching new power management controls and redundant power architectures with the goal of providing these ships with resilient electrical power. » back to top

We develop digital twins of systems and subsystems on DoD platforms, for hull structural health monitoring, self-healing autonomous machinery, and smart electrical grids. Our unique understanding of artificial intelligence and machine learning is applied to the development of efficient and accurate virtual worlds. Methods to test and train unmanned systems in all domains ensures resiliency of these technologies and systems. Computational Fluid Dynamics The Art of the Possible PacMar Technologies is a leader in computational fluid dynamics and physics-based motion simulation and optimization. Engineering Expertise: Advanced Seakeeping & CFD Analysis Engineering Development from TRL1 to TRL6 Hydro-Mechanical Simulation Concept Design Mechanical Systems Design Amphibious Vehicles Uncrewed Refueling Remote Vessel Operation Undersea Vehicle Design Case Study with AppliedCAx Building prototypes to validate designs is costly and limits innovation. PacMar Technologies has created virtual sea states in which we can simulate and optimize design iterations before constructing physical prototypes and testing in real-world conditions. We utilize advanced simulation tools STAR-CCM+ and our in-house code AEGIR in the product development cycle to validate product designs. Developing the Next Generation of Aquatic Vessels As a company, PacMar Technologies prides itself on tackling tough challenges and being able to take an idea from a napkin sketch to a detailed design and simulation, then finally constructing and delivering a fully functional physical prototype that goes to the sea for in-water testing. Our Honolulu location offers an optimal setting for real-world validation as the challenging sea state and uniquely rough waters makes for a dynamic testing ground. Designs that can perform here can perform anywhere. Designing for the Rigors of the Ocean The ocean is an unforgiving environment, and the main challenge of maritime design is the sea itself. Watercraft designs and prototypes taken to the sea must be ready for those challenges and be able to overcome the dynamics of a harsh, deep ocean environment. Surface vessels, underwater vehicles, as well as amphibious vehicles, all have to deal with waves, the surf zone, currents, and wind, all coming together in an incompressible fluid - whether it's on the surface or below. Innovative Success Powered by Simulation PacMar Technologies has had many successful surface ship programs in its history. Oneof the most successful has been their Sea Blade line of surface ships. Novel in its approach to hydrodynamics and performance, they leveraged STAR-CCM+ to run simulations on "many, many" iterations, doing different benchmark comparisons against different hull designs. The most comparable hull ship is a Deep-V hull design. Looking at the Sea Blade vs the Deep-V, they showed a 23% reduction in slamming and a 50% reduction in roll response. They're also able to go up an additional 2 knots in speed. These are key metrics for operator safety, allowing the operator to not only go faster but also avoid injuring crew and damaging machinery or electronics. These designs would not be possible without having access to simulation. Without the reduction in risk, the cost of developing cutting-edge technologies would not have been possible.

This month PMT celebrates the U.S Navy’s 246th birthday. As a proud supporter of the Office of Naval Research (ONR), PMT has been working with ONR on projects for over 40 years in areas like small/large boats/ships design, science, technology and research – contributing to the ever-evolving capabilities of today’s Fleet. PMT Celebrates the Navy’s Birthday » back to News Article by Communications Staff Photo Credit: Gray Gibson/U.S. Navy via AP This month PMT celebrates the U.S Navy’s 246th birthday. As a proud supporter of the Office of Naval Research (ONR), PMT has been working with ONR on projects for over 40 years in areas like small/large boats/ships design, science, technology and research – contributing to the ever-evolving capabilities of today’s Fleet. This year, the theme of the Navy’s birthday celebration is “Resilient and Ready”. The Navy has a history of overcoming any challenge, including the ongoing global pandemic. Here at PMT we face challenges everyday but live by this same motto as we strive to do our best work and are excited to continue to support Navy programs now and into the future. PMT wanted to reflect on a few of our notable past and present ONR projects. Pictured: Seaflyer, Lifting-Body Technology Demonstrator. Pictured: Ultra Heavy-Lift Amphibious Connector (UHAC), MDG built a half-scale prototype of a ship-to-shore connector. Pictured: BLB-65. This boat has a dihedral bow lifting body (BLB) with trailing edge flaps, active control system, and designed for efficiency and seakeeping. Pictured: ORADTS program. This project combined all of PMT ’s capabilities to create an at-sea automated refueling and data transfer system for unmanned surface vehicles. The resulting system, which was generated using in-house CFD and physics-based motion simulation and optimization, decoupled the motions of the capture mechanism from the host platform enabling more reliable transfer of fuel and data regardless of sea-state Pictured: DARPA Manta Ray program. This program seeks to develop a new class of long-duration, long-range, payload-capable UUVs at an acquisition and lifecycle cost significantly less than current payload-capable UUVs. Pictured: Under the IMS program, PMT built a 36 ft medium-scale vessel in support of towing drop stitch inflatable structures as well as advancing automation, controls, and autonomous capability across a range of sub-systems in support of that program. Pictured: Sea Slice was a 105’ high-speed low-motion SWATH demonstrator built and tested for ONR by PMT and Lockheed Martin. » back to top
