TEDxPSU - Jack Langelaan: NASA Green Flight Challenge

Jack Langelaan is an Assistant Professor in the Department of Aerospace Engineering at The Pennsylvania State University. One of his research areas focuses on flight path planning for small robotic aircraft, specifically on enabling "bird-like" flight by exploiting winds aloft. This can greatly improve flight efficiency, enabling a host of novel civil and scientific missions that require long duration or long distance flight. In 2011 he was leader of Team, winner of the NASA Green Flight Challenge. The Team's aircraft, the world's first four-passenger electrically powered aircraft, flew 403 passenger miles per gallon over a 195 mile course at 107 miles per hour: this is more than double the fuel efficiency of a Toyota Prius at double the speed, and roughly seven times the fuel efficiency of typical small aircraft. In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
