This NASA sponsored STTR project will investigate methods for close-out of large, liquid rocket engine, nickel or stainless steel nozzle, coolant channels utilizing robotic laser and pulsed-arc additive manufacturing (AM)methods. Structural jacket to coolant channel land area interface strength will be quantified and metallurgical characterization completed. Process optimizations will be conducte ...

Launch safety and efficiency requires timely and accurate wind, thermodynamic and pressure information from the surface to 20 km height, and lightning risk identification. A Doppler radar now provides wind measurements that satisfy this requirement at the Eastern Test Range. Thermodynamic soundings are provided by intermittent radiosondes on launch day. Typical intervals of an hour or more between ...

The tiltwing class of aircraft consists of vehicles with the ability to rotate the wing and propulsion system as a unit a full 90 degrees from the standard fixed wing configuration to one in which the wing and thrust axis become perpendicular to the body axis. This thrust vectoring capability allows the aircraft to utilize thrust borne flight for vertical takeoff and landing as well as the convent ...

Luna will team with Dr. John Bowers of UCSB to develop an Optical Frequency Domain Reflectometry (OFDR) system-on-chip using heterogeneous silicon photonics to enable a minimal weight structural health monitoring system. This system-on-chip will be the building block for distributed sensing interrogation systems that are the size of a deck of playing cards. This lightweight, rugged, and miniature ...

In this Phase II STTR project, the proposed collaborative effort between UTC, AFIT, and ULRF represents a crucial step forward for AM. UTC’s unique AM optimization and process control framework, constructed entirely from experimental sensor data collected in-situ, will finally transfer technology from our SLM test bed system to state-of-the-art and commercial-grade systems, including a Concept ...

The S-351 mini-sub is a prototype of the Dry Combat Submersible (DCS). This prototype was established as a means of risk reduction prior to a full commitment to the DCS program. Both of these platforms have an operational need to transit with minimum operator fatigue safely to a pre-defined point and covertly deploy and retrieve SEALS. To meet these operational needs, these platforms require upgra ...

Polymer matrix composites are increasingly replacing traditional metallic materials in NASA launch vehicles. However, the repair and subsequent inspection methods for these materials are considerably more complicated. Typically, a composite laminate patch must be manually fabricated and bonded or co-cured to the damaged structure. To ensure high quality patches with sufficient compaction and l ...

Laser & Plasma Technologies (LPT), teamed with the National Science Foundation (NSF) Center for Lasers at the University of Virginia (UVA), proposes an advanced optical fiber coupled hybrid spectroscope for in situ characterization of organic compounds. The proposed approach provides information on organic compounds by analyzing spectra obtained from Laser Induced Breakdown Spectroscopy (LIBS) an ...

The Phase I STTR project will develop an ignition system for a high density hybrid rocket motor using non-toxic, storable, ionic liquid oxidizers and high density polymer fuels. The program will also research fuel additives to boost ISP and fuel regression rate of the high density, high regression ate fuel.. This high density propulsion system resolves one of the chief drawbacks of hybrid rock ...

Supporting aerospace mission readiness, a system is needed that allows for composite repairs without the current roadblocks imposed by ovens, autoclaves, and expensive tooling. Cornerstone Research Group (CRG), its subsidiary NONA Composites, and the University of Dayton Research Institute (UDRI) presents NASA with the opportunity to obtain a rapid and robust method for on-site composite structura ...
