The topic defines the problem as the development and demonstration of computationally efficient tools capable of modeling sound propagation in an urban environment for creating auralizations of UAM vehicles. The tools would be suitable for eventual integration with the NASA Auralization Framework (NAF).The topic requires a set of modules to be delivered which will integrate with existing NAF infr ...

This solicitation calls for online quality control to be applied to In-Space Manufactured (ISM) additive manufactured parts. Our proposed approach is integrated precision scanning of the additive manufactured (AM) parts and feedback of that data back into AM layer by layer process control. The goal is to augment Space Manufacturing AM process controls with verifiable feedback enabling improved p ...

Quantum Opus is excited to propose compactifying, enclosing, and automating ALL of the required vacuum, cryogenics, and electrical systems of a superconducting nanowire single-photon detection system into a 14-inch tall by 17-inch wide by 18-inch deep package and re-engineering the optical collection mechanisms to be compatible with existing NASA telescope infrastructure. The end product will be a ...

The overall objective of the SBIR is to develop a high performance, inexpensive, three-band thermal infrared camera system, suitable for deployment in Unmanned Airborne Systems and CubeSats. This imaging system will be capable of mapping thermal features on the surface of the earth with a high revisit rate and high spatial resolution. Xiomas believes the Three Band Infrared Detector (TBIRD) Syst ...

This SBIR project will develop a manufacturing method for nuclear fuels that can be universally applied for space-power systems that utilizes a dust-free uranium oxide production unit. For the particular application to nuclear thermal propulsion, in which one wishes, (1) to maximize hydrogen propellant heating, and (2) to reduce fission product gas release and reactor particulates into the engine ...

A receiver system for use in LIDAR consisting of an optical filter and optical spectrometer based upon two-photon absorption is proposed. The filter and spectrometer both use dispersion from excited state transitions of atomic rubidium to create a birefringent medium. The birefringent medium of the optical filter rotates the polarization of light so that it is transmitted through crossed polariz ...

The adoption of high energy lithium sulfur batteries hinges on significant improvements in charge/recharge cycle life. Cycle life is limited by migration of dissolved polysulfide species which creates an electrochemical short circuit. In this NASA SBIR, Navitas Systems proposes to develop an atomically precise and bifunctional membrane separator for lithium sulfur batteries that impedes polysulf ...

A key component in the Alkali Metal Thermal to Electric Converter (AMTEC) is the electrode that is generally sputter deposited on the beta"-alumina solid electrolyte (BASE). Electrode deposition, as it is now practiced however, is a random process that covers active sites on the BASE and places many electrode pore openings at inactive sites. This proposal describes a novel fabrication process for ...

Safety-critical aerospace applications have become increasingly dependent on a software component. However, conventional approaches to increasing the software reliability of these systems have focused on purely programming aspects. While these methods can all lead to techniques which should minimize the number of flaws in the logic of programs, none claim to result in generation of code with zero ...
