BRS Founder to Speak on Electric VTOL Aircraft at CAFE Foundation Prior to Oshkosh

Boris Popov

BRS Aerospace founder Boris Popov will be a main presenter at the 2018 Electric Aircraft Symposium to be held prior to EAA AirVenture in Oshkosh, Wisconsin.

Popov's presentation, entitled Sustainable Aviation/VTOL Flight Emergency Parachute Utilization, is part of the two-day event sponsored by the CAFE (Comparative Aircraft Flight Efficiency) Foundation's conference to be held July 21-22 at the University of Wisconsin Oshkosh Alumni Welcome and Conference Center.

CAFE Electric Aircraft Symposium, Part Three

CAFE Foundation

CAFE FoundationThe last six speakers closed out the afternoon session with aircraft, regulations, and ways to manage all the new traffic.

Mark Moore, NASA, Silicon Valley VTOL Air-Taxi Study

Dr. Moore started with an overview of all the unused Los Angeles helipads, required by law on every new high rise since 1974 until eliminated by Mayor Eric Garcetti in 2014. Most were not being used, and part of their original purpose – to allow life-saving drop-ins by Fire Department helicopters – seems reasonable even today. Moore asked what if we really tried to use these rooftops?  Continue reading "CAFE Electric Aircraft Symposium, Part Three"

One jet turbine, three generators, 24 ducted fans and 74 "effectors" to control it all.

John Langford: Aurora Flight Sciences and the Lightning Strike

Dr. Langford opened the second day with background on strides his firm has made in creating an unpiloted vertical takeoff and landing machine. The Lightning Strike is a 10,000 to 12,000 pound, high-speed craft with a turbine from partner Rolls-Royce and triple generators from partner Honeywell, all driving 18 wing-mounted and six canard-mounted electric, variable-pitch ducted fans. Both wings and canard pivot to allow vertical takeoff and landing, and tilt to horizontal mode to allow up to 400-knot cruising. This speed would be tactically beneficial.  Continue reading "CAFE Foundation Electric Aircraft Symposium, Part Two"

Creating a Standard for Electrified AC

Ron Gremban's Cessna is now electric.

Ron Gremban is an early developer of plug-in electric hybrid (PHEV) automobiles, having converted hundreds of Toyota Prius vehicles to extend their electric-only range and make them even more practical real-world automobiles.

As part of the Electric Aircraft Symposium hosted by the CAFE Foundation in April, he shared some of his concerns about potential safety concerns for another form of EV, electrified aircraft.

He proposed standards for knowing when an electric aircraft motor is “On,” explaining that electric aircraft motors do not turn over when their controller is on “O,” as spectators at the Green Flight Challenge could appreciate. Normal aviation practice is for the pilot to yell “Clear!” and verify that bystanders have indeed cleared the area before the engine is fired up. The noise and visual indications let people know the engine is active, and even that is not always enough to prevent some unfortunate prop strikes each year.

Green Flight Challenge, The Winners

The Pipistrel team.

Monday October 3 marked the Green Flight Challenge Expo, sponsored by Google and staged under the control tower at the center of Moffett Field, home of NASA Ames Research Center.

The four airplanes that flew in the Green Flight Challenge at Charles M. Schulz Sonoma Country Airport in Santa Rosa, California, were there, along with Greg Stevenson's full-size mockup of his GFC design and a Pipistrel Virus that had won an earler NASA/CAFE Personal Air Vehicle (PAV) Challenge.

Twenty exhibitors were on hand to show their approaches to green aviation, and three rows of tents protected exhibitors and their displays from the rain that started mid-afternoon. At about 11 a.m., attendees were brought to Building 3, in which NASA's acting Chief Technical Officer Joe Parrish recognized the GFC winners. Continue reading "Green Flight Challenge, The Winners"
