The proposed innovation is a heterogeneous multi-robot team developed as a platform for effective subsurface planetary exploration. State-of-art robotic exploration is based on single-robot systems with human controllers augmented by limited automation. This system requires near-constant communication and a single failure results in the end of the mission. A multi-robot system offers more efficien ...

An orifice element is commonly used in liquid rocket engine test facilities to provide a large reduction in pressure over a very small distance in the piping system. Orifice elements are used in propellant lines, feed systems, plume suppression systems and steam ejector trains. While the orifice as a device is largely effective in stepping down pressure, it is also susceptible to a wake-vortex ty ...

The proposed SBIR Phase II program will lead to the validation of a state-of-the-art Large Eddy Simulation (LES) model, coupled with a Ffowcs-Williams-Hawkings (FW-H) farfield acoustic solver, for supporting the development of advanced engine concepts, including innovative flow control strategies for attenuation of their jet noise emissions. During Phase I, the LES/FW-H model was validated against ...

TRS proposes to develop a simple-to-use, launch capable, ultrasound transducer that is capable of producing the necessary bandwidth to accurately determine in vivo bone characteristics that correlate to loss of strength in astronauts in long-duration space flights (microgravity). The transducer will be capable of measuring backscatter, attenuation, reflectivity and other ultrasound parameters of ...

Given the extended duration of future missions and the isolated, extreme, and confined environments, there is the possibility that stress-related behavioral conditions and mental disorders (DSM-IV-TR) will develop. The overarching goal of this project is to deliver an integrated system that will track physiological signals (heart rate and heart rate variability) and behavioral signals (sleep wake ...

Naturally occurring in the stratosphere, ozone plays a significant role in many atmospheric reactions, cloud formation, and is the key player in shielding harmful UV radiation. In the troposphere, it is a criteria pollutant produced via photochemical smog reactions, and is key in the formation of organic aerosols from VOCs. A better understanding on the distribution of ozone and its influences o ...

Random number (RN) generation is the key software component that permits random sampling. Software for parallel RN generation (RNG) should be based on RNGs that are good serial generators, but also are suitable for concurrent execution, i.e. RNs produced by different concurrent processes must be statistically independent of one another. With dependence, the work done on one concurrent process wi ...

Prognostic monitoring capabilities for space exploration aircrafts are crucial to enable safety and reliability in these platforms. Nokomis proposes to develop and mature a system which exploits electromagnetic emissions to identify degradation in avionics components and determine the probability of failure and remaining useful life (RUL). Over time, the deterioration of components under stress ...

The Area-I team has developed and fabricated the unmanned Prototype-Technology Evaluation and Research Aircraft or PTERA ("ptera" being Greek for wing, or wing-like). The PTERA is an extremely versatile and high-quality, yet inexpensive flight research testbed that serves as a bridge between wind tunnel and manned flight testing by enabling the low-cost, low-risk flight-based evaluation of a wide ...
