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"

Pioneers and New Directions

Sustainable Aviation Syposium - Part Three

Several speakers presented talks on controlling the coming wave of unmanned aerial systems traffic management (UTM).

Dr. Parimal Kopardekar on Safely Enabling Low-Altitude UAS Operations

Dr. Kopardekar of the NASA Ames Research Center showed that he and NASA have done a thorough job of understanding drone control, and planned a sequence of actions to address the issues.

A recent series of tests in isolated areas and a planned three further steps will see increasing authority being given operators. Phase 1, to have been accomplished in August last year, reserved testing in areas over water or away from population centers and unlikely to be used by general aviation. The unmanned aerial system pilot still had responsibility for sorting out problems. Phase 2 and beyond allow operations beyond the operator’s line of sight, with increasing levels of interactions with manned aircraft and over increasingly populated areas.

Dr, Kopardekar's four-part road to the future of UAS integration into the airspace.

Motors, Batteries, Solar Cells and Hydrogen – Power for Future Flight

Sustainable Aviation Symposium – Part 2

Dr. Joseph Kallo and the Power Behind the HY 4

While we're still waiting for the battery breakthroughs that will let us fly infinite distances without recharging, several motors await energizing from whatever source is available. Speakers at the First Sustainable Aviation Symposium included solar energy, new battery chemistries, fuel cells and hydrogen, or even the regenerative power of the air itself in their presentations. Continue reading "Motors, Batteries, Solar Cells and Hydrogen – Power for Future Flight"

Sustainable Aviation Symposium


The First Sustainable Aviation Symposium was held May 6 and 7 at the Sofitel Hotel in San Carlos, California - just around the corner from the Hiller Aviation Museum. Over 120 attended, rubbing elbows with the speakers and learning about the latest in electric aviation and forward-thinking approaches to the challenges to come from increasing numbers of drone flights and possible "optionally-piloted" manned aircraft. We’ll first look at the aircraft now flying or soon to fly with electric, solar, and even hydrogen power. Continue reading "Sustainable Aviation Symposium"
