Elektra One Aircraft at “the electric avenue 10”

16 May 2010

PC-Aero, a German aircraft design, engineering and consulting company for general and business aviation, will display its prototype electric-powered aircraft, the Elektra One, at “the electric avenue 10, the Expo for Sustainable Mobility”, in Friedrichshafen, Germany, 3-6 June. Elektra One made its debut a few ago at AERO 2010, also in Friedrichshafen.

The 1-seater Elektra One is the first member of a planned E-Plane family including electric aircrafts from 2 (Elektra Two) up to 4 passengers (Elektra Four.

The battery and solar-cell powered Elektra One is built of lightweight fiber composite structures. The plane is sailplane-like, with a glide ratio of more than 20 at 160 km/h cruise. Maximum power is 16-20 kW, and range is more than 400 km (249 miles) with a flight time of up to more than 3 hours. The prototype of the Elektra One is in the final stage of fabrication. Elektra Two and Elektra Four are in an advanced design phase.

The aircraft will be presented in the series version close before the first flight (with the three wheel landing gear and cockpit interior installed).

250 miles isn't much range.  This system looks like it's better suited to a self-launching sailplane than an aircraft intended to operate under continuous power.  Even there, piston power accomplishes the same end with conventional construction and much lower cost.

I don't think electric aircraft are going to be practical for quite a while.  The battery technologies which make long-range EVs practical are still not adequate for a passenger aircraft.

Actualy fuel cell powered small craft are comming along fast.. tho currently only in the unmanned type id expect it to creep into manned small planes soon after as fuel cell costs go down.

This maybe a "prototype electric-powered aircraft" from this company but I've been reading about electric self-launching sailplanes for a number of years. Sailplane pilots are a special breed who put a premium on quiet, eco-friendly operation.

As batteries performance goes up 2x to 4x and price goes down to 1/2 or even 1/4 current level and ultra light high performance PV + light weight materials become affordable we may see more e-planes around. Development cost may be paid by the armed forces for use as surveillance crafts.

However, e-boats may prosper sooner because they don't have the same weight restrictions.

Not realy likely harveyd remember the army already has access and uses ultra high energy batteries because they can afford to buy and use batteries that only work 20 cycles.

They are however looking into batteriesw beyond lith ion but that may be 50-100 years before it bears fruit. So for now they mostly are looking at advanced fuel cells and new fuel tanks to provide enough energy storage for these things.
