Peter Sripol is part of FliteTest, a group that sells electric model aircraft and components and produces some wild and wooly YouTube videos of their exploits.  The group’s products are mostly budget items, with simple aircraft quickly constructed the norm.  One example, the Simple Solar radio-controlled plane, can be built for under $60, and flies on two coreless motors.  Flite Test has quick build kits and FPV (First Person View) radio systems that allow a pilot to view, through an on-board camera, what a (really tiny) person on board the model would see.  This level of miniaturization and commodity-level pricing allows FliteTest to provide STEM (Science, Technology, Engineering and Math) kits to schools at the grade and high-school levels.

Better Battery Materials – Asphalt?

Dean Sigler Batteries, Electric Aircraft Materials, Sustainable Aviation 0 Comments

Asphalt, Graphene, and a Lithium Coating Mike Williams, reporting for Rice University in Houston, Texas, writes, “A touch of asphalt may be the secret to high-capacity lithium metal batteries that charge 10 to 20 times faster than commercial lithium-ion batteries, according to Rice University scientists.” We’ve written about James Tour and his laboratory before.  He and his students come up with a plethora of new energy ideas and are able to demonstrate some exciting outcomes.  His latest effort mixes asphalt with conductive graphene nanoribbons, and then electrochemically coats the composite with lithium metal to form a battery anode. The anode, when combined with a sulfurized-carbon cathode, was used in full batteries for testing.  The results seem a bit incredible, with …

Smart Fabrics Generate Energy Several Ways

Dean Sigler Batteries, Electric Aircraft Materials, Solar Power, Sustainable Aviation 0 Comments

We see a great deal about wearable energy-generating fabrics, garments that will help keep the wearer warm, or cool, or visible because of built-in piezo-electric generators in the makeup of the fabric.  Several researchers are taking this to the next level, creating new warps and woofs of materials that will create energy from a greater range of energy inputs. Elias Siores and the University of Bolton In 2011, Professor Elias Siores and associates at the University of Bolton in the UK created a flexible fiber that could harvest energy from movement and light.  Siores said it was flexible enough to be woven into “a sail, window curtain or tent and generate power”.  The material was recognized as a major innovation …

Capturing Carbon and Making Airplanes from It

Dean Sigler Electric Aircraft Materials, Solar Power, Sustainable Aviation 0 Comments

Climate scientists have tracked the growing percentage of carbon dioxide (CO2) in the air, and noted a correlation between that rise and global warming.  Scientists from Michael Mann to Benjamin Santer have measured the changes in CO2 levels against climate change, with 97 out of 100 climate scientists accepting that human activities and rises in CO2 (and other greenhouse gases such as methane) are affecting our overall climate. Not to start an argument about this matter, this entry looks at a novel method of removing CO2 from the atmosphere and using it to make possible carbon materials that would be used in aerospace and other components.  The question of carbon removal usually includes some method of storing it.  Futurism.com has …

What We’re Looking Forward to at AirVenture 2017

We’re looking forward to seeing progress in electric aircraft, and this year may be an opportunity to see real breakthroughs. Two from Pipistrel Besides its regular lineup of high-quality aircraft, Pipistel will have two Alpha Electro trainers on display in their display area.  This is the first time these aircraft will be seen in America, and they’ll be at the right of AirVenture’s main entrance gate in sites 86 and 87. In the Ultralight Area Mark Beierle will display and fly Bravo, Richard Steeves’ e-Gull.  This red, white and blue gem features a power system made from Zero Motorcycle components and boasts an impressive rate of climb and exceptional short field capabilities. Another ultralight, the EMG-6 developed over the last …

EViation Electric Aircraft: Demanding Disruption

Aviation Week reports from the Paris Air Show on a “disruptive” entry in electric aviation.  Eviation, founded by Omer Bar Yohai, is primed to deliver a change in transportation as we know it.  Yohai says, “The dominant solutions available today are deeply flawed and demand disruption.” The company’s promotional video only hints at the company’s intentions.  Their vision statement on their web site, though, indicates a skyward aspiration: “Making electric aviation the fast, competitive and clean answer to on-demand mobility of people and goods.”  Aviation Week’s Noam Eshel quotes Bar Yohai as saying, “We design, test and build the tools that will enable future of regional transit by air, changing consumers’ perception of both distance and time.  Five years from …

A Swan among the Ultralights

Dean Sigler Electric Aircraft Materials, Electric Powerplants, Sustainable Aviation, Uncategorized 0 Comments

At this year’s Aero Friedrichshafen, Modern Wings showed off their Swan Ultralight, a nicely packaged machine that can fly on either fossil fuels or electricity.  Of course, we’ll feature the electric version here. The Swan E115-22 is an electrically-powered airplane of 115 kilograms (253 pounds) empty weight powered by a 22-horsepower motor.  That empty weight puts it solidly into U. S. FAR Part 103 territory and SSDR (single-seat deregulated) requirements in Great Britain, and a 120 kilogram (264 pound) version complies with Regulation 120 in Germany.  Maximum takeoff weight is 300 kilograms (660 pounds), heavier than the 524 pounds Part 103 allows, and possible legal depending on how local FAA inspectors view batteries as part of empty or total weight. …

Five Representative Exhibitors at the E-Flight Expo

Aero, an annual event at Friedrichshafen, Germany, highlights the beginning of the European air show season.  E-Flight Expo has been a regular part of this for the last several years, and displays the latest in electric flight technology.  Certainly the most forward-looking part of the show, the Expo grows every year.  Several exhibitors helped further the advanced look this year. MGM Compro With at least five aircraft powered by their electric power systems on display, MGM Compro showed great market strength.  The Czech firm has 16 of its motors atop each Volocopter 200, with one as a propulsor in the tail.  Their motors power the Magnus e-Fusion aerobatic trainer, several GP gliders, the S.R.O. Song motorglider, and any number of …

Otherlab’s Cardboard Drone – “A Pizza Box… Shaped into a Wing”

Dean Sigler Batteries, Electric Aircraft Materials, Sustainable Aviation 0 Comments

A disposable drone that will make a one-way trip to a disaster area won’t add to the suffering if it dissolves within a few weeks of delivering its life-saving cargo.  That’s the promise of the “Aerial Platform Supporting Autonomous Resupply Actions” (APSARA), currently being developed by Otherlab, a San Francisco-based group specializing in next-generation creations.  Funded by DARPA (the Defense Advanced Research Projects Agency), APSARA is part of their ICARUS program (Inbound, Controlled, Air-Releasable, Unrecoverable Systems).  The acronyms are becoming overwhelming. Disposable medical supplies are a commonplace in today’s clinics and hospitals.  A recent chat with a nurse elicited her concern that medical supplies were so readily disposable.  Latex or nitrile gloves, single-use syringes, and protective paper covers and wraps …
