  1. AeroAstro At MIT & Wind Tunnel Demonstration Chelsea He, SameeraPonda, Sunny Wicks Women’s Graduate Association of Aeronautics and Astronautics (WGA3) Massachusetts Institute of Technology July 17, 2012

  2. Overview • What We Do • How We Got Involved • Wind Tunnel Demonstration

  3. What is AeroAstro? engineering management planetary sciences aerospace software environment transportation energy others computational engineering robotics and controls

  4. Autonomous/Humans in the Loop Systems • Six collaborating AeroAstro labs researching challenges of unmanned aircraft and ground vehicles, and developing algorithms enabling collaboration between human operator and autonomous planners • Applications include military use, emergency response, disaster relief, agricultural mapping, and manufacturing.

  5. SPHERES • Begun 10 years ago as AeroAstro student project, now three on ISS • Provides DARPA, NASA, and other researchers with a long term, replenishable, upgradable testbed for validation of high risk metrology, control, and autonomy technologies for use in formation flight and autonomous docking, rendezvous and reconfiguration algorithms.

  6. Protecting Against Blast-Induced Brain Injury • Developing/optimizing nanoengineered materials for protecting US soldiers from blast threats • Demonstrated current military helmet ACH is safe for blast events and that a face shield could significantly mitigate blast-induced Traumatic Brain Injury

  7. Reducing Aviation’s Environmental Impact • AeroAstro team is modifying ground operations to reduce aircraft fuel burn and engine emissions • Applying MIT-developed algorithms to coordinate push-backs, eight four-hour test periods at BOS saved >15,000 kg fuel, reduced taxi times by 20%

  8. MIT 150 Open House: April 30, 2011 "We were stunned by the organization, scale of the experiments shown, and sheer number of staff and students involved. We participated all across the 'tute, the kids almost running between buildings as I read the options ahead. We saw the Army helicopters, water rockets, and all the exhibits in Johnson and the Rockwell Cage. We did materials experiments, were inBuilding 33 and 41for events, saw the ship models and viewed parts of lectures on robotics in Course 2. We loved all the activities in Stata [including] ...the DARPA autonomous vehicle... The flying car, motorized shopping cart, and the students trying to commercialize the Braille label maker were also big winners... The best part was over dinner, when my kids sat there with paper and penciltrying to invent a different way to make the helium blimps they saw race.” From an MIT President Susan Hockfield email to the MIT community.

  9. Future of Exploration Symposium One panel, moderated by Prof. Larry Young and astronaut-professor Jeff Hoffman, included alum-astronauts Buzz Aldrin, TJ Creamer,Terry Hart, Rick Hauck, Mike Massimino, and, via downlink from the ISS, Cady Coleman.

  10. “Hello” from Space And, one of the biggest hits of the 150 was the greeting to the Institute from Space, which we arranged, featuring alums Mike Fincke, Cady Coleman, and Greg Chamitoff.

  11. Other Cool Things We Do…

  12. Women in Aerospace Symposium • 12-14 top female PhD candidates from US and UK • Faculty panels • Keynote speakers • Yvonne Brill, pioneer in rocket propulsion • Dr. Wanda Austin, CEO of Aerospace Corp. • Cady Coleman, astronaut

  14. What to Look For • Airfoil shape & orientation force air to flow faster over top side of the wing than over the bottom side of the wing • By Bernoulli's Principle, the faster flowing airstream above the exerts less pressure on the wing • Stall: when the angle of attack is too large and unstable flow ensues

  15. Wind Tunnel Demo • Objective: Illustrate basic aerodynamics concepts such as lift, drag, stall using a low speed flow visualization wind tunnel • “Little Smokey” wind tunnel http://www.grc.nasa.gov/WWW/k-12/WindTunnel/build.html • Materials (< $100) • Plywood • 2” x 4” wood • Polycarbonate sheet • Computer cooling fan • PVC pipes • Straws • Dry ice
