The SBIR.gov award data files now contain the required fields to calculate award timeliness for individual awards or for an agency or branch. Additional information on calculating award timeliness is available on the Data Resource Page.
SBC: HARP ENGINEERING LLC Topic: N19AT003
The performance of a composite material is heavily influenced by the strength and toughness of the interlaminar region, which is the resin rich area between the plies of a fiber reinforced composite. The interlaminar region generally provides a direct path for crack propagation since no continuous reinforcement is present and is often the cause of failure in materials subjected to cyclic loading s ...STTR Phase I 2019 Department of DefenseNavy
SBC: MANTEL TECHNOLOGIES, INC. Topic: N19AT013
The U.S. Navy seeks methods to improve the fuel economy of marine diesel engines through utilization of waste heat. Low temperature engine jacket water, lubrication oil, and aftercooler air are largely untapped streams of thermal energy on these ships, but their utilization circumvents many operation challenges associated with exhaust gases. For example, variable and high exhaust gas temperatures ...STTR Phase I 2019 Department of DefenseNavy
High Speed Spinning Scroll Expander (HiSSSE)- Organic Rankine Cycle for Increased Naval Ship Power Density and Fuel EfficiencySBC: Air Squared, Inc. Topic: N19AT013
Waste heat from Naval diesel generators provides significant opportunity to introduce organic Rankine cycles (ORC) to increase their fuel efficiency. The objective of the proposed effort is to design and demonstrate a high-speed, spinning scroll expander (HiSSSE) ORC as a power dense waste heat recovery system for diesel generators on ships. The system will leverage Air Squared’s spinning scroll ...STTR Phase I 2019 Department of DefenseNavy
SBC: SPECTRAL ENERGIES LLC Topic: N19AT013
The STTR topic N19A-T013 seeks innovative technology to improve the power density and efficiency of propulsion and power generation devices. To address this challenge, Spectral Energies in collaboration with its academic partner Dr. Rory Roberts at Wright State University proposes to develop a compact heat recovery system based on a supercritical CO2 based Rankin Cycle. At the end of the STTR prog ...STTR Phase I 2019 Department of DefenseNavy
SBC: CORNERSTONE RESEARCH GROUP INC Topic: N18AT012
Unmanned underwater vehicles (UUVs) are currently limited in the type of missions they can perform. Limited available power limits which sensors can be run or for how long, and also limits the duration and range of the mission. More efficient propulsion systems would increase the power available to the UUV payload. Improved power distribution systems and control systems would also increase the ava ...STTR Phase I 2018 Department of DefenseNavy
SBC: VALOR ROBOTICS, LLC Topic: N19AT011
The objective of the Phase I proposal is to investigate the application of controlled cavitation cleaning technology in conjunction with gecko-inspired mechanical adhesion and soft elastomeric applicators for use in non-intrusive EOD operations. This investigation requires the proof-of-concept testing and validation of a controlled cavitation cleaning mechanism, and a soft robotic gecko-inspired m ...STTR Phase I 2019 Department of DefenseNavy
SBC: TDA RESEARCH, INC. Topic: A18BT018
Defense against chemical weapons is a critical DoD requirement. An effective defense requires the development of unique respirator systems that prevent inhalation of chemical warfare (CW) agents. In addition, the protective equipment exposed to CW agents must not pose a residual hazard after use in the battlefield. Existing respirator canisters remove CW agents, but they do not self-decontaminate ...STTR Phase I 2019 Department of DefenseArmy
SBC: FLIGHTPROFILER, LLC Topic: AF19BT001
RADAR (and similar direct or observational meteorological measuring equipment) has limitations (inability to measure low vis conditions, line-of-site, limited vertical (z-axis), expensive/heavy equipment is required, etc.). To solve these limitations, a Purdue University team (launched via a SBC called FlightProfiler) has developed a technology that delivers a computer generated X-Y-Z environmenta ...STTR Phase I 2019 Department of DefenseAir Force
SBC: GLOBAL CIRCUIT INNOVATIONS INC Topic: AF19BT001
A growing number of electronic applications within the Air Force, such as devices for power conditioning and distribution, RF power amplification, and high power lasers have been identified for increased heat transfer requirements to maintain operational temperatures at acceptable levels while increasing the performance through higher power. However, this same target research that requires increas ...STTR Phase I 2019 Department of DefenseAir Force
SBC: NOVAA LTD Topic: AF19BT001
High-speed and reliable tactical communications have empowered the Air Force with overwhelming information superiority, and control of the battlespace. However, the effectiveness of such systems has been impacted by the increasingly congested and contested spectral environment, compounded by the reliance on half-duplex systems. The latter rely on time- or frequency-division to separate transmit an ...STTR Phase I 2019 Department of DefenseAir Force
