Microcalorimetry is an enabling technology for many NASA space science missions because it permits detection of single photons at high rates with unprecedented energy resolution and efficiency. This remarkable technology relies upon superconducting devices that must be cooled below 100 mK. We propose to construct a doubly-integrated circuit in which critical features of microcalorimeter pixels on ...

The increased aircraft safety potential of active flow control using synthetic jets - specifically, using synthetic jets on the leading edge of the wing to delay flow separation - is of critical importance. Delaying flow separation could allow an aircraft to recover from adverse conditions that would otherwise result in a loss of control. Active flow control using synthetic jet actuators has been ...

This STTR Phase I project describes the development of a high-performance, robust, portable, and compact laser ultrasonic system for multi-purpose Non-Destructive Evaluation (NDE). Laser ultrasonic has now become a valuable tool for on-line inspection, demonstrating its advantages in the steel and aerospace industries. Non-destructive laser ultrasonic inspection equipments use large size laser com ...

We will design and implement an interface between the Paramesh computational libraries, developed and used by groups at NASA GSFC, and the Cactus computational framework, developed primarily by scientists at Louisiana State University, the RI on this proposal. Our innovation falls in the domain of adaptive mesh refinement (AMR), a technique to focus computational resources in regions of small sca ...

HyPerComp Engineering Inc. (HEI) and Utah State University (USU) propose to develop technology for lightweight composite materials for use in composite structures suitable for both cryogenic and damage tolerant environments. The proposed effort will incorporate previous work performed by HEI in the cryogenic performance of composite materials as well as previously developed improved impact technol ...

Innovators working to revolutionize air travel through personal aviation pioneers need innovative aircraft design tools. Vehicle Sketch Pad (VSP) is an aircraft geometry tool for rapid evaluation of advanced design concepts. VSP will be extended to include support for the modeling of aircraft structural layout and a modular system for integrating engineering analyses. These modifications will a ...

The primary focus of Integrated Vehicle Health Management (IVHM) has been on faults due to hardware failures. Yet software is growing in complexity, controls critical functionality under a wide range of conditions and does so with greater autonomy. Furthermore, software errors have negatively impacted major missions. Runtime recovery from software faults is gaining momentum in research community ...

Redefine Technologies, along with researchers at the University of Colorado, will use three redundancy methods to decrease the susceptibility of a spacecraft, on a mission survivability level, to electronic failures anywhere throughout the spacecraft. By using Field Programmable Gate Array (FPGA) chips, we will analyze the spacecraft-wide benefits of: *triplicating the logic and RAM on-board eac ...

An Integrated Sensing and Control of Aeroelastic Deformation (ISCAD) Toolbox is proposed. Specif-ically, this toolbox will provide a methodology, both hardware and software, that serves to compensate for uncommanded de?ections of ?ight systems. This toolbox is meant to augment existing procedures for design of both aircraft and autopilots by providing additional capabilities that address aspects u ...

The ability to quickly estimate flight vehicle behavior in an operational environment is particularly important since engineers from a variety of disciplines require accurate predictions in order to plan flight test experiments, expand aircraft operating envelopes safely, and have access to diagnostic methods when problems arise. In order to minimize risks, and to maximize compatibility with prese ...
