Space Operations In The Suborbital Space Flight Simulator And Mission Control Center: Lessons Learned With Xcor Lynx, Pedro Llanos, Christopher Nguyen, David Williams, Kim O. Chambers Ph.D., Erik Seedhouse, Robert Davidson May 2018

Space Operations In The Suborbital Space Flight Simulator And Mission Control Center: Lessons Learned With Xcor Lynx, Pedro Llanos, Christopher Nguyen, David Williams, Kim O. Chambers Ph.D., Erik Seedhouse, Robert Davidson

Pedro J. Llanos (www.AstronauticsLlanos.com)

This study was conducted to better understand the performance of the XCOR Lynx vehicle. Because the Lynx development was halted, the best knowledge of vehicle dynamics can only be found through simulator flights. X-Plane 10 was chosen for its robust applications and accurate portrayal of dynamics on a vehicle in flight. The Suborbital Space Flight Simulator (SSFS) and Mission Control Center (MCC) were brought to the Applied Aviation Sciences department in fall 2015 at Embry-Riddle Aeronautical University, Daytona Beach campus. This academic and research tool is a department asset capable of providing multiple fields of data about suborbital simulated flights. …


The Next Step Beyond Identifying Field Variability: Integrating Unmanned Aerial Systems Into The Farm Management Workflow, Kevin A. Adkins, Christen C. Bailey, Aspen E. Taylor Apr 2018

The Next Step Beyond Identifying Field Variability: Integrating Unmanned Aerial Systems Into The Farm Management Workflow, Kevin A. Adkins, Christen C. Bailey, Aspen E. Taylor

Kevin A. Adkins, PhD

Precision agriculture strives to manage variations in the field in order to increase yield while adapting input factors to preserve resources and decrease production costs. Unmanned aerial systems (UAS) are advancing precision agriculture by allowing for nondestructive and convenient, as well as cost and time efficient mapping of spatial variation in fields with higher spatial resolution than previous methods. However, while there is much anticipation regarding the potential role for UAS in precision agriculture, their role still requires additional application-based testing. The objective of this work was to explore how growers best integrate the UAS product into their farm workflow. …

Microscale Investigation Of Thermo-Fluid Transport In The Transition Fil, Region Of An Evaporating Capillary Meniscus Using A Microgravity Environment, Kenneth D. Kihm, Jeffrey S. Allen, Kevin P. Hallinan, David M. Pratt Jul 2016

Microscale Investigation Of Thermo-Fluid Transport In The Transition Fil, Region Of An Evaporating Capillary Meniscus Using A Microgravity Environment, Kenneth D. Kihm, Jeffrey S. Allen, Kevin P. Hallinan, David M. Pratt

Kevin Hallinan

In order to enhance the fundamental understanding of thin film evaporation and thereby improve the critical design concept for two-phase heat transfer devices, microscale heat and mass transport is to be investigated for the transition film region using state-of-the-art optical diagnostic techniques. By utilizing a microgravity environment, the length scales of the transition film region can be extended sufficiently, from submicron to micron, to probe and measure the microscale transport fields which are affected by intermolecular forces. Extension of the thin film dimensions under microgravity will be achieved by using a conical evaporator made of a thin silicon substrate under …

High Speed Flight At Low Altitude: Hazard To Commercial Aviation ?, Paul F. Eschenfelder , Capt. Mar 2011

High Speed Flight At Low Altitude: Hazard To Commercial Aviation ?, Paul F. Eschenfelder , Capt.

Paul F. Eschenfelder

Commercial aircraft are capable of, and in fact, do, operate at high speed (>250 knots indicated airspeed [KIAS]) at low altitude (below 10,000’ above ground level) worldwide. Design, construction and certification standards for these aircraft were developed over 40 years ago. Since the development of these standards populations of large flocking birds have increased dramatically in many parts of the world. Yet neither design/construction standards nor operational practice have changed to reflect the new threat. Subsequent serious damage resulting from recent collisions indicates change is necessary. Since 2003, flight rules in Canada and the United States have been amended, …


Integrating Avian Radar Into The Aviation Operating Environment, Richard Sowden, Paul Eschenfelder Mar 2011

Integrating Avian Radar Into The Aviation Operating Environment, Richard Sowden, Paul Eschenfelder

Paul F. Eschenfelder

Avian radar technology has matured to the point where robust data and analysis tools are now able to provide the aviation industry with high quality information to support bird strike risk mitigation activities. The aviation operating environment is dynamic and challenging with complex interactions between the primary bird strike risk mitigation stakeholders; airport operators, air traffic service providers and flight crews. The transfer of this proof of concept technology into a suite of tools that is integrated into the aviation industry requires the engagement and support of the user community in the next critical evolutionary step of this emerging technology. …
