Tehachapi Soars with New ideas – Day 2

The annual Experimental Soaring Association Western Workshop spills over the Labor Day weekend, starting with a welcome barbecue/potluck Friday evening and an official kickoff on Saturday.  Sunday features more technical presentations and this year – an organization business meeting and a closing talk about moon shots. Pelicans, Albatross and Perpetual Flight Phillip Barnes, an accomplished aerodynamicist, photographer and expert on soaring birds, links all his interests and skills in his web site, How Flies the Albatross. This year, he brought his knowledge to bear on a design for a flying machine that would pull energy from the air it flies through to power its electric motors – Coulomb Keeper. He described the design process behind it in a talk titled, “Aircraft Energy Gain from an Atmosphere in Motion.” Keeper is an outgrowth of Phil’s earlier aircraft concept, Faraday.  Both are derived from his desire to fly like the Albatross, which manages to circumnavigate the Antarctic Circle in seemingly perpetual flight.  …

Learning About Energy Regeneration from Birds

Phil Barnes has one of the most fascinating web sites on the Internet, combining his aerodynamic expertise and love of soaring birds with his radical approach to staying up perpetually (or until the pilot grows exhausted).  Albatross, birds he’s studied for decades, soar along the tops of ocean waves, seeking food for themselves and their broods, often traveling thousands of miles before setting down.  They have the advantage of bifurcated brains, able to stay awake in one hemisphere of the brain while the other hemisphere nods off, a trait they share with dolphins. Would it be possible for humans to tap the energy in the air to soar for indefinite periods?  Could truly fuel-free flight be a reality?  Phil is betting both sides of his brain on an affirmative answer to that. His presentation at this year’s Experimental Soaring Association Western Workshop in Tehachapi, California was more than an addendum to previous work in this area, but an expansion of …

Tehachapi 2013 – Baby Bowlus and Silent Electro

Dean Sigler Electric Powerplants, Sustainable Aviation 2 Comments

Tehachapi is a one-time railroad stop, 4,000 feet in the high mountain desert near Mojave, California.  Trains don’t stop there very often these days, but multi-engined, two-mile-long bearers of cargo and commerce run over the tracks 50 times a day, making the long haul toward Bakersfield or Mojave. Hawley Bowlus helped build the Spirit of St. Louis and later taught the Lindberghs to fly sailplanes, with some lessons taking place in the high desert air above Tehachapi.  Today, the once bare hills are covered with over 5,000 wind turbines, their giant rotors pointed into the prevailing westerlies.  At the base of these hills, Mountain Valley Soaring has a base, and Jeff Byard has a hangar that hosts the annual meeting of the Experimental Soaring Association. Members gather to hear talks on the history, technology, and joy of soaring – and get in some flying between – or instead of – lectures . This year, the Labor Day weekend centered on …
