SBC: Material Flow Solutions, Inc. Topic: MDA16T001
Based on the results of our Phase I work, one significant barrier to optimizing battery performance lies in understanding the relationship between bulk solids and particle flow properties and the flow into the die. Our hypothesis: an increase in quality batteries production can be achieved if powder preparation process can be optimized and the die filling process controlled. We feel that control o ...STTR Phase II 2019 Department of DefenseMissile Defense Agency
SBC: MRL MATERIALS RESOURCES LLC Topic: MDA17T001
Metallic additive manufacturing (AM) is an attractive technology for the production of lethality test articles due to the potential for significantly reduced lead time and manufacturing cost. However, in order to be effective in providing accurate lethality data, the properties of the AM material have to match closely the properties of conventionally manufactured alloys found in real threat target ...STTR Phase II 2019 Department of DefenseMissile Defense Agency
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: McCoy Consulting, LLC Topic: N19AT007
The objective of this proposed effort is to increase the power and torque density of rotating electric machinery for Naval applications by up to 50%. This aggressive goal will be achieved by developing the novel homopolar AC machine (HAM) topology. This relatively un-studied topology relies on solenoidal field and armature coils, making manufacturing simpler than traditional machines. The HAM elim ...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: INTRABAND, LLC Topic: N11AT011
Monolithic surface-emitting (SE) semiconductor lasers hold promise for significant advantages over edge-emitting lasers in terms of both reliable operation, scaling the CW single-mode output powers into the multi-watt range, and manufacturing cost. Grating-coupled (GC) surface emitters offer a path to achieving single-spatial-mode, single-frequency CW operation, with the added advantage that relat ...STTR Phase II 2019 Department of DefenseNavy
SBC: VIRTUAL EM INC. Topic: AF19AT003
Virtual EM and Case Western Reserve University are teaming to propose a standoff cardiopulmonary sensing technology to aid remote monitoring of airman and others ' physiological state of health both in the field and in the office environments. While the pulmonary sensing unit could be operated meters away, the cardio signals are picked up in closer proximity to the body.STTR Phase I 2019 Department of DefenseAir Force
SBC: Guidestar Optical Systems, Inc. Topic: AF19AT006
Locating objects that vibrate is a way to discern potential threats and locate targets. However, current vibrometry technology typically measures only the global vibration of target and cannot create an extended spatial measurement of the vibration profile of the target. These solutions cannot identify what the target is, nor can they locate potential weak spots on the target, because they lack sp ...STTR Phase I 2019 Department of DefenseAir Force
SBC: Applied Optimization, Inc Topic: AF19AT008
The research objective of the proposed work is to increase the efficiency of the laser return of a Sodium Guide Star Laser (SGSL) reflected off the sodium layer for increased reliability and applicability of the artificial guide star technique. During Phase I, we will demonstrate the concept of maximizing the SGSL signal returns using numerical simulations that account for the effects of atmospher ...STTR Phase I 2019 Department of DefenseAir Force
Advanced Diagnostic for Performance and Combustion Characterization in Rotational Detonation Rocket Engine (RDRE)SBC: Exo-Atmospheric Technologies LLC Topic: AF19AT011
Rotating Detonation Rocket Engines (RDRE)are being developed to take advantage of the near instantaneous heat release potential of detonation waves versus conventional deflagration-based chemical reactions in combustion applications. However, the detonation product environment is extreme and current instrumentation to measure wall / surface conditions within the detonation chamber are lacking.
