This Phase I SBIR will establish the feasibility of developing a collinear three wavelength source for an in-situ, 1800, back scatter nephelometer. The three wavelength source is being developed to facilitate on-board validation measurements of airborne remote backscatter lidar. Currently, commercial nephelometers utilized for in-situ validation measurements employ wavelengths that are both not ...

Bridger Photonics Inc. (Bridger) proposes developing the most efficient, compact, rugged, low-power consumption and cost-effective UV ozone differential absorption lidar (DIAL) transmitter available. Bridger will demonstrate pulse energies above 0.5 mJ with a goal of 1 mJ/pulse with a pulse repetition frequency of 1 kHz. The proposed transmitter will enable widespread deployment of ozone DIAL s ...

In response to NASA 2015 SBIR Topic H4.02, Air-Lock proposes to define the maximum allowable contact stress for Titanium bearings. The modulus of Titanium is lower than legacy spacesuit bearing materials (Stainless Steel). Due to this, Titanium bearings are more susceptible to deflection under man and plug load scenarios. Bearing deflection causes a limited number of balls to absorb the full load ...

In Phase II, the QSI-Vanderbilt team seeks to develop a system-level diagnostics and prognostic process that incorporates a "sense and respond capability," which first uses error codes and discrete sensor values to correctly diagnose the system health including degradations and failures of sensors and components, and then invokes appropriate prognostics routines for the assessment of RUL and perfo ...

This SBIR Phase II proposes the development and delivery of a compact, space qualifiable, diode-based seed laser system that utilizes a digital controller to allow autonomous acquisition of lock to the required wavelength in remote environments for multi-wavelength flight and space-based lidar applications. Successful development of this technology, due to its compact, efficient, and reliable des ...

Precision Combustion, Inc. (PCI) proposes to develop and demonstrate an innovative high power density design for direct internal reforming of regolith off-gases (e.g., methane and high hydrocarbons) within a solid oxide stack. The resulting enhanced heat transfer design offers the potential for higher overall efficiency, simplifies the system, and enables further compactness and weight reduction o ...

As NASA space missions become longer in duration the need for high efficiency power generator sets that can operate on NASA logistical fuel become critical. Historically NASA has used fuel cells as part of the energy solution. Space bound energy and power systems require rapid start and stop cycle times as well as high power densities. The high operational efficiency, coupled with the use of logi ...

There has been a renewed push across NASA centers and programs to make Systems Engineering & Integration (SE&I) processes more efficient and results-oriented than the current cumbersome and expensive cross-checking processes using text documents, and transition to a repeatable and a cost-effective process of Model Based Systems Engineering (MBSE). In parallel, Systems Health management (SHM), with ...
