Pulsed Fiber Optics Lasers As Highly Sensitive Sensors, Hanieh Afkhamiardakani Nov 2018

Pulsed Fiber Optics Lasers As Highly Sensitive Sensors, Hanieh Afkhamiardakani

Shared Knowledge Conference

An interferometer or resonator is a device in which optical beams of specific frequencies circulate with minimal losses. These losses are completely compensated by the gain inside a laser resonator. A small perturbation introduced inside the laser can affect its frequency, which in turns becomes a metric of that perturbation. The perturbation is usually caused by an electric or magnetic field, rotation, acceleration, nonlinear index of refraction etc. Tiny changes of optical frequency are monitored by superimposing the laser field and a reference field (from the same laser) on a detector. This technique requires creating a laser in which two …

Effects Of Graphical Weather Information Versus Textual Weather Information On Situation Awareness In Meteorology, Stefan Melendez M.S.A., Andrew Dattel Ph.D., Christopher Herbster Ph.D., Debbie Schaum M.A., Andrey Babin Aug 2017

Effects Of Graphical Weather Information Versus Textual Weather Information On Situation Awareness In Meteorology, Stefan Melendez M.S.A., Andrew Dattel Ph.D., Christopher Herbster Ph.D., Debbie Schaum M.A., Andrey Babin

National Training Aircraft Symposium (NTAS)

Prior to a flight, pilots gather meteorological information in order to assess the weather conditions pertaining to their flight and to make decisions based on it. This information can come in various formats, such as text and graphical weather information. Research has shown that people have varying learning preferences and that most people prefer visual learning to verbal learning (i.e., graphical over text). It is hypothesized that this difference in learning preference can affect the way pilots interpret and apply the information they obtain prior to their flight. The researcher hypothesizes that graphical weather information has a greater, more positive …


Development Of A "Multi-Cut" Payload For Use In Stratospheric Ballooning Missions, James Flaten, Joey Habeck, Noah Biniek, Steven Smeaton, Austin Langford, Jordan Diers, Isaac Krieger Aug 2016

Development Of A "Multi-Cut" Payload For Use In Stratospheric Ballooning Missions, James Flaten, Joey Habeck, Noah Biniek, Steven Smeaton, Austin Langford, Jordan Diers, Isaac Krieger

2017 Academic High Altitude Conference

The ability to cut strings (AKA lines) during stratospheric ballooning missions has a wide variety of uses including, but not limited to, (a) flight termination (i.e. cutting payloads away from the main balloon), (b) cutting away excess lift balloon(s) to slow ascent rate (and possibly achieve float), (c) cutting away ballast weights to slow descent rate or increase ascent rate, (d) cutting away burst balloon(s) on descent to avoid parachute entanglement, and (e) cutting away payloads which are intended to return to the ground independently, for experimental purposes. We report on the development of a “multi-cut” payload box that uses …


Applying Newton’S Law Of Cooling When The Target Keeps Changing Temperature, Such As In Stratospheric Ballooning Missions, James Flaten, Kaye Smith, Erick Agrimson Jun 2016

Applying Newton’S Law Of Cooling When The Target Keeps Changing Temperature, Such As In Stratospheric Ballooning Missions, James Flaten, Kaye Smith, Erick Agrimson

2017 Academic High Altitude Conference

Newton’s Law of Cooling describes how a “small” system, such as a thermometer, comes to thermal equilibrium with a “large” system, such as its environment, as a function of time. It is typically applied when the environment is in thermal equilibrium and the conditions are such that the thermal decay time for the thermometer is a constant. Neither of these conditions are met when measuring environmental (i.e. atmospheric) temperature using a thermometer mounted in a payload lofted into the stratosphere under weather balloons. In this situation the thermometer is in motion so it encounters layer after layer of atmosphere which …

The “Stratospheric Cricket Keeper” – Developing A Simple“Life-Support” Payload For High-Altitude Balloon Missions, Lucas Kramer, Chad Serba, James Flaten Jun 2015

The “Stratospheric Cricket Keeper” – Developing A Simple“Life-Support” Payload For High-Altitude Balloon Missions, Lucas Kramer, Chad Serba, James Flaten

2017 Academic High Altitude Conference

Exposure to the environmental conditions of “near-space” (AKA the stratosphere) is quickly fatal to nearly all forms of animal life. It is even challenging to build a sealable enclosure that can keep insects (crickets) alive through the dramatic and simultaneous pressure and temperature drops experienced during a high-altitude balloon mission. This poster describes the development of a rugged “cricket keeper” in which we were able to fly crickets to the stratosphere and, quoting the words of JFK, “return (them) safely to the earth!” This “life-support” payload had large windows (for the view!) and included Arduino-logged temperature and pressure sensors, an …


Aviation Security Impacts Of Meteorological And Climatic Disruption, Melanie Wetzel Jan 2015

Aviation Security Impacts Of Meteorological And Climatic Disruption, Melanie Wetzel

Aviation / Aeronautics / Aerospace International Research Conference

Commercial and military flight operations are frequently imperiled or disrupted by meteorological conditions. Severe weather events and climate-related factors create aviation security impacts on airport siting and reliability, human safety, economic stability, military defense strategy, aircraft routing and computer systems vulnerability. Climate trends have been associated with increased frequency of storm surge incursions at coastal airports, intense snowfall accumulations, runway closures due to rainstorm runoff, extended periods of fog/stratus restrictions and severe-weather related risk from lightning, hail and icing. The economic and safety impacts of these events are being incorporated into long-term planning by the U.S. Department of Defense (DoD), …


Weather Research Requirements To Improve Space Launch From Cape Canaveral Air Force Station And Nasa Kennedy Space Center, William P. Roeder, Lisa L. Huddleston, William H. Bauman Iii, Kelly B. Doser Nov 2014

Weather Research Requirements To Improve Space Launch From Cape Canaveral Air Force Station And Nasa Kennedy Space Center, William P. Roeder, Lisa L. Huddleston, William H. Bauman Iii, Kelly B. Doser

Space Traffic Management Conference

Weather has a large affect on operations at Cape Canaveral Air Force Station (CCAFS) and NASA Kennedy Space Center (KSC). Weather is the leading source of scrubs and delays to space launch from CCAFS/KSC. Weather has an even larger impact on ground processing as space launch vehicles and payloads are prepared in the months before space launch. Many of those operations are very sensitive to weather. In addition, the weather in Florida is notoriously difficult to predict, especially during the summer when rapid deep convection can occur in minutes. Finally, the weather can be extremely subtle in this area during …


Using High-Resolution Weather Data To Improve Winter Weather Maintenance Operations, Michael Baldwin Mar 2013

Using High-Resolution Weather Data To Improve Winter Weather Maintenance Operations, Michael Baldwin

Purdue Road School

Substantial resources are required for winter maintenance operations. This presentation focuses on more accurate and precise weather information that can help reduce the uncertainty related to winter weather, resulting in improved decision-making and significant cost savings for winter operations.
