Thermoelectric Cranial Cooling Collar (TEC-3)
Amount: $120,865 Topic: N211-013
Helmet systems for hearing and head protection are essential for the safety of maintainers, flight deck crew, and rotary-wing aircrew operating in extremely loud environments. Many of the features that make these helmets effective for noise abatement—e.g., limited venting and edge seals—also act as a thermal barrier increasing the risk of hyperthermia. In this SBIR, we focus on developing a lightweight personal cooling unit capable of delivering targeted head and neck cooling for 12+ hours without degrading helmet protection or the effectiveness of its wearer. Our proposed approach, a Thermoelectric Cranial Cooling Collar (TEC-3), integrates highly novel and proven technologies to deliver significant thermal performance—rapidly cooling >40°F below ambient—in a lightweight, low-profile, and durable system with hot-swappable rechargeable batteries for 12+ hours of continuous cooling.

CLAD: Compound Lever-Actuated Dead Man Switch for Blast Nozzles
Amount: $141,056 Topic: AF192-063
Compound lever-actuated dead man (CLAD) with simple, rugged design that proffers a myriad of benefits to plastic media blast (PBM) operators, including: reduced grip force to initiate and maintain activation; ergonomic, adjustable grip for enhanced comfort; and rugged construction capable of 100+ repeated 48-inch vertical drops and >500 hours’ cumulative use.

Non-Pyro Battlefield Effects Replication
Amount: $95,772 Topic: A18-091
Our objective is to design a multi-aspect Battlefield Effects Replication (BFER) system, assess its feasibility and technical merit, and lay the framework for future prototyping and development. In Phase I, we will develop a modular BFER system comprising a portable, ruggedized cradle with universal docking system for easy installation, reconfiguration and control of multiple "plug-n-play" modules providing myriad visual, thermal and audio effects.

Naval Special Warfare (NSW) Diver Thermal Human Interface
Amount: $992,530 Topic: N15A-T012
During Phase I of this project, WElkins identified, developed and established the technical merit of potential improvements to the SEAL Delivery Vehicle (SDV) Diver Human Thermal Interface (DHTI). In Phase II, we shall build prototypes of the next-generation DHTI, including a multi-zone Liquid Cooling Garment, Quick-Disconnect Coupling, and Fluid Delivery Lines. These prototypes will be tested in simulated subsea conditions to validate the thermal and operational improvements modeled in Phase I analysis.

Naval Special Warfare (NSW) Diver Thermal Human Interface
Amount: $149,977 Topic: N15A-T012
This effort, led by WElkins, LLC and its research partner, Wheaton College, proposes to develop and test a next generation SDV human thermal interface system with major technical improvements in three areas: the thermal interface garment, umbilical connections, and fluid delivery system. To improve the thermal interface garment, WElkins proposes replacement of the current generation tube suit with a multi-zone printed circuit heat exchanger, which provides a larger and more effective surface area for heat exchange; this next generation heat exchanger will feature enhanced passive insulation and be integrated directly into the dry/wet suit for improved wearability. Improvement of the umbilical connectors will leverage WElkins experience developing custom hydraulic-pneumatic connectors for its medical devices; innovations will target ease-of-use and reliability in low-visibility, limited-dexterity conditions. On the fluid delivery system, this effort proposes enhancements to the fluid delivery lines and couplings to improve thermal efficiency across the system; again, WElkins medical device R&D experience and current technology will support the proposed improvements. Following requirements definition and preliminary concept, WElkins and Wheaton College will model, simulate and evaluate the feasibility of the proposed improvementsboth as independent elements and a comprehensive systemusing computerized fluid and thermodynamic tools.
