Fault-Tolerant Control (FTC) is an emerging area of engineering and scientific research that integrates prognostics, health management concepts and intelligent control. Impact Technologies and the Georgia Institute of Technology, propose to build off of a strong foundation in fault-tolerant control (FTC) research performed with NASA in past years to mature the applicability of this technology and ...

Future NASA exploration missions will rely on remote operation of robots. As human explorers move further away from Earth, robotic precursors will scout destinations and robotic assistants will perform tasks to reduce astronaut risk and workload. 3D visualization is a key component of how humans will interact with robots for these missions. When the operator engages a robot using visualization, th ...

Airfoils produce more lift and less drag when the boundary layer is attached to the airfoil. With most aircraft there are combinations of airspeed and angle of attack where the boundary layer at least partially detaches from the airfoil. Reducing boundary layer detachment increases lift and reduce drag reducing fuel consumption and improving control for the pilot. Two methods known to improve b ...

The ability to quickly and reliably simulate high-speed flows over a wide range of geometrically complex configurations is critical to many of NASA's missions. Advances in CFD methods and parallel computing have provided NASA the core flow solvers to perform these simulations. However, the ease of use of these flow solvers and the reliability of the results obtained are a strong function of t ...

During recent robotic field tests, NASA investigated the use of intelligent planetary rovers to improve the productivity of human explorers on planetary surfaces. For these field tests, a remote Science Team built rover plans to collect data that supplements astronaut EVA and a remote Flight Team supervised the execution of these plans. This model of operation requires the Science Team to generate ...

Balcones Technologies, LLC proposes to adapt technologies developed by and resident in The University of Texas at Austin Center for Electromechanics (CEM) in the areas of superconducting Trapped Field Magnet (TFM) motors, magnetic bearings, terrestrial and space-based flywheel energy storage systems, and air-core generators to address STTR 2010-1 Subtopic T3.01, Technologies for Space Power and Pr ...

Innovative Imaging and Research, a small technology development company, has teamed with the University of Southern Mississippi Instrument and Cryogenics Research Laboratory to integrate existing NASA Stennis Space Center heritage cryogen level monitoring technology with noncontact optical methods and advanced signal processing to create a 21st century liquid cryogen level measurement technique. ...

As 'fly-by-wire' technologies become more prevalent in the aerospace systems, the need to develop innovative monitoring, diagnostic and fault tolerant techniques for the electrical systems is becoming obvious. Among all the possible electrical system failures, two types of failures are considered the most frequent, and hence most critical: intermittent disconnection in connectors, and capacitance ...

The proposed project will develop a new technique for invariant inference and embed this and other current invariant inference and checking techniques in an easy-to-use tool. The result will enhance an engineer's ability to use formal methodsÂ? generating, editing, reviewing, proving and testing invariants Â? and improve productivity in verification and validation of safety and correctness ...

The proposed research focuses on the development of a new adaptive control methodology for active control of wing aerodynamic shape to effect distributed aerodynamic forces and moments for maneuvering and stabilization of flexible airframes without moving control surfaces. The new aero-effected flight control will be achieved using output feedback adaptive control of distributed bleed across aero ...
