STEM Presentation at Los Angeles County Air Show

 ANTELOPE VALLEY CHAPTER PRESENTATION AT THE LOS ANGELES COUNTY AIR SHOW

The Antelope Valley Chapter of the Society of Flight Test Engineers brought a laptop based flight simulator to the L.A. County Airshow STEM tent. Show goers were challenged to complete an offset landing task to earn their pilot wings. Members Mike Delany, Richard Starke, John Bretz, and Ryan Kessler staffed the SFTE table. 

FLIGHT TEST HISTORICAL FOUNDATION STEM PRESENTATION A HIT AT THE LOS ANGELES COUNTY AIR SHOW

DSC 9200S In addition, the Society of Flight Test Engineers aided the Flight Test Historical Foundation in an effort to represent the effect on the how atmosphere pressure effects us and how we can measure it.  The hands-on activity was designed by Board Member Don Weiss, a Northrop Grumman Engineering Test Pilot. 

Each student was introduced to Boyle's Law (the law that describes how a gas volume increases, the pressure of the gas decreases in proportion. Similarly, as volume decreases, the pressure of the gas increases ) andCharles Law (the law that describes how a gas expands as the temperature increases; conversely, a decrease in temperature will lead to a decrease in volume) . 

 

Both of these laws effect our everyday lives.  Ever take a bag of chips up into the mountains and watch it expand (mine blew up once!) or put a half full plastic bottle of water in the frig and remove it later to find that it was now crushed?

To demonstrate what they learned, each child was given the opportunity to build a simple but working altimeter and was allowed test it in a small vacuum chamber.  Don made this both a fun and learning activity for the children, our future engineers and scientists.
