The current state of the art for production computational fluid dynamic (CFD) simulations in both the Entry, Descent and Landing (EDL) communities and modeling of hypersonic vehicles is the solution of steady-state problems on fixed computation grids. However, the majority of relevant challenge problems are unsteady. Accurate simulations of such unsteady phenomena currently require computational g ...

Corvid Technologies (Corvid) and North Carolina State University (NCSU) are employing a novel moving Discontinuous Galerkin with Interface Conservation Enforcement (MDG+ICE) approach. The MDG+ICE method represents a fundamentally grounded and break-through approach and is specifically designed for flows with discontinuities and therefore especially attractive for hypersonic flows. During Phase I, ...

The proposed work aims to demonstrate significant improvement in AlGaN-based detectors and detector arrays by employing single crystal AlN substrates, which practically eliminates leakage induced by screw dislocations. By employing defect controlled APDs on single crystal AlN, we aim to demonstrate sensitivity over the whole UVC range (120 - 275 nm) while being solar and visible blind. We will pro ...

This NASA SBIR Phase I proposal presents an unprecedented method to make high emissivity surfaces for space radiators. Integration of laser surface processing and robotics enables fast surface structuring for any shapes and any sizes. With our successful history in a variety of laser 3D processing, this proposal has a great potential to succeed. A proof of concept demonstration will be carried out ...

Anuma Aerospace seeks to develop the conceptual design for, and determine the technical and economic feasibility of, a Persistently-Elevated, Gas-free, Aerostatic Sensor Utility System (PEGASUS), which will work like a data buoy in the sky, continuously collecting and transmitting weather data from the marine atmospheric boundary layer (ABL) with the data being made available via application progr ...

In Phase I we developed a software capability for predicting the future positions of ocean drifters. We demonstrated the capability to predict drift for objects of varying shapes and train models based on historical observations. In Phase II we will leverage this software to perform high volume experimentation through which we will fully develop trained models using historical data for both passiv ...
