This project addresses three modeling elements relevant to NASA's IADS research and ATD-2 project, two related to ramp operations at primary airports and one related to departure status at secondary airports. Departure scheduling requires departure status information from secondary airports that lack surface surveillance. We propose a method using aircraft transponder activation and data science ...

Air traffic control research, air traffic control operations and user operations rely on simulators that predict the future time history of three-dimensional aircraft trajectories. Such predicted trajectories are fundamental inputs to a wide variety of planning, monitoring and control tasks, including airline seasonal fleet planning, pre-departure flight planning, real-time airspace and airport lo ...

A wide variety of flow management techniques is employed every day in the NAS, from strategic Ground Delay Programs (GDP's) with national scope to local Miles-In-Trail (MIT) restrictions that affect traffic over a specific fix. The choice of the flow management technique to employ and the timing, extent, and other parameters associated with the technique are determined by controller judgment info ...

As the air transportation system becomes increasingly autonomous over the next twenty years, there will be an increasing need for monitoring capabilities that operate in the background to identify anomalous behaviors consistent with either safety or efficiency deficiencies. Today, these behaviors are largely detected after an incident has occurred. In July 2013, an Asiana Boeing 777 flew too low a ...

Development of a robotic manipulator called Momentum Device Actuated Canfield (MoDAC) Manipulator for integration on to the assistive free flyers (AFF) being developed by NASA for the International Space Station is proposed. Integrating a robotic manipulator with an appropriate end-effector to an AFF provides the capability to perform several autonomous functions such as material handling, fetchin ...

Crown Consulting, Inc. proposes a new method of concept verification and validation for autonomous operations and identifying emergent behaviors. This method integrates several Internet technologies to enable massively parallel execution of National Airspace System (NAS) simulations in a cloud environment, vastly increasing the number of Monte Carlo simulation runs that can be executed in a given ...

Odyssey proposes a new fault management planning and design tool and methodology that uses state-based simulations with programmable dynamic state definitions to provide early assessments of fault management system scope and cost. The tool will utilize models developed in SysML to capture system characteristics and relationships between system components as well as mapping of functionality to req ...

NASA's future human exploration missions will include remotely operated rovers performing surface exploration and science, as well as free-flyers to reduce the need for human Extra Vehicular Activity (EVA). As astronauts move deeper into space, it will be necessary for them to manage these robotic assets with less support from ground controllers. A flexible approach is needed to build and revise p ...

The vibroacoustic characteristics of structures are vital in determining the operational envelope and mission feasibilities. The sources of vibroacoustic excitation are mainly due to noise generated by the launcher during ignition, lift-off, and atmospheric flight. Typically, foam or fiberglass claddings and cores or acoustic liners which incorporate resonating chambers are used to prevent the tr ...

The proposed SBIR program targets the development of Rad-Hard by Design (RHBD), 1200 V-class SiC (planar) vertical DMOSFETs and power Schottky rectifiers for future NASA space missions. Single die ratings of > 1200 V, > 75 A, > 225?C and compliance to a NASA-certified radiation hardness assurance program are targeted for the proposed SiC power devices. The target application for these devices invo ...
