NASA seeks tailored airframes and structures to reduce structural mass in support of the NASA Aeronautics Strategic Implementation Plan (2015), following the Roadmap for Ultra-Efficient Commercial Vehicles, Subsonic Transport. Tailored structures are comprised of the right materials, at the right place, in the right orientation, in the right amount. Whatever the material or structural configuratio ...

Future Turboelectric or Hybrid Electric aircraft requires high power density and efficiency power generation components for which superconductors are likely key enablers. Therefore, there is a need for light-weight, high-performance superconducting wire with sufficiently high operating temperature, is stable, and available in long piece-length for coil fabrication. Improved 2nd generation magnesiu ...

The availability of low AC loss magnesium diboride (MgB2) superconducting wires enables much lighter weight superconducting stator coils than with any other metal or ceramic superconductor. This, together with Hyper Tech's capability to fabricate long piece-length (potentially 60 km) wires, in turn enables lighter superconducting motors/generators, essential components in the turboelectric aircraf ...

The proposed SBIR program by Virtual AeroSurface Technologies (VAST) focuses on the development of a novel variant of pulsed blowing active flow control in which chemically-based flow control actuators are utilized to create high-impulse pulsed jets from discrete reaction chambers with a flowable propellant mixture provided to each. Chemically-based actuation is capable of producing high-impulse ...

One of the primary shortcomings identified during the NASA sponsored CFD Vision 2030 Study conducted during 2012-2014 was that the generation of meshes suitable for CFD simulations constitutes a principal bottleneck in the workflow process as it requires significant human intervention. CAD simplification and cleanup is one of the most user-intensive steps of the CFD mesh generation process and it ...

We propose a novel computational method for generating data needed to create decision strategies for condition-based monitoring algorithms that can effectively differentiate between a healthy system and different types of defects in a damaged system. Currently, the only means available to generate this data are physical testing which is time consuming and expensive, and simplified computer models- ...

The performance gains and weight reductions from using Ceramic Matrix Composite(CMC) turbine blades in both the High Pressure Turbine(HPT) and Low Pressure Turbine(LPT) will be determined. Shrouding HPT rotor blades becomes feasible when low density CMC materials replace current metallic HPT rotor blades. The proposal has two components. The first is to identify stage efficiency improvements a ...

In order to improve high-temperature oxidation and corrosion resistance of critical superalloy components in turbine engines innovative processing methods must be devised to improve coating and materials properties at a higher reliability and lower costs. Whether or not thermal barrier coating are applied to the engine components, the resistance to oxidation and hot corrosion relies on metallic co ...

This work will focus on the development of a highly capable avionics subsystem and machine learning algorithms to provide early warning of potential failures of critical subsystems on small UAS. This modular system will consist of networked onboard monitoring nodes capable of observing operations and providing notification of off-nominal conditions to the autopilot as well as the operator, mitigat ...

Flight research is a critical element for the validation of ground test measurements and the maturation of new technology. Experimental measurement systems that offer fast response, high accuracy and reliability, and require minimal modification of the flight vehicle are needed to conduct flight research more effectively. There have recently been significant advances in the use of one such technol ...
