Claire Tomlin is pushing the envelope of aerospace design by building a new class of autonomous helicopters, with support from the National Science Foundation. These aircraft don’t need a pilot steering them remotely because they navigate themselves. Tomlin believes these helicopters will have applications in the military, civilian search and rescue, and many more venues.
In a decade dominated by the Great Depression, the inventors of the 1930s were desperately trying to make a living. They come up with some simple yet ingenious inventions that are still practical necessities in our fast-paced life. Featured inventions include: the helicopter, xerography, the parking meter, the walkie talkie, and the electric guitar.
Geologist John Goodge looks for clues about Antarctica's past in the two percent of the continent that is not covered in ice. The University of Minnesota, Duluth professor studies rocks that help provide evidence about how this desolate continent has formed and changed over time. In late 2010 and early 2011, he spent several weeks in the field with other scientists, visiting a dozen sites in Antarctica, along 1200 miles of mountains. They collected 2500 pounds of rocks, which are now being analyzed back in the states.
This episode highlights efforts by various individuals to help save animals. Features include a woman's journey to save orphaned orangutans and a man's mission to relocate rhinos by helicopter. Also in this episode, a group of Asian elephants show off their skills and intelligence. Part of the "All In" series.
Stacey Combes, a biomechanist at Harvard University, and her team are using high speed cameras to help them study how dragonflies pull off complicated aerial feats that include hunting and mating in mid-air. They can fly straight up, straight down, hover like helicopters and disappear in a blur. Combes is also exploring the use of dragonflies for mosquito control.
Aeronautics is the science of flight as well as the theory and practice of aircraft navigation. Any machine that flies through the air falls into the field of aeronautics. This includes helicopters, airplanes, as well as space vehicles such as the SpaceX Dragon and the retired NASA space shuttles. Aerodynamics is a branch of physical science which deals with the motion of air and the way that it interacts with objects in motion.
Biologist Ken Dial has documented in extraordinary detail how birds are put together and the mechanics of how they take to the air. With support from the National Science Foundation, Dial and his team at the University of Montana Flight Lab use x-rays and high speed video to better understand the mechanics of bird flight. Dial’s more than 2,000 flight hours as a pilot in a wide range of aircraft adds another dimension to his research. Perhaps, by mimicking what birds have learned over millions of years, aircraft wings could change shape to accommodate both slow and fast flight, or a helicopter propeller’s shape might be altered to be more efficient.
