What’s in store for electric and hybrid-electric aircraft?

Electrically powered aircraft are not exactly poised to convey the holiday-making hordes to their destinations for a little while yet, but recent developments in this field offer more than a hint of what might be possible in the years to come. Few people, I think, were left unimpressed by aviator André Borschberg’s airmanship when he managed to keep his solar powered Solar Impulse HB-SIA aircraft aloft for more than 26 hours, reaching jet airliner altitudes and cruising at a rather sedate average speed of just under 21 knots.

A somewhat faster, though less durable, record breaker is the Italian SkySpark, which reached 250km/h some fourteen months ago with pilot Maurizio Cheli at the controls. This first test flight lasted for eight minutes, but it confirmed the viability of battery powered fixed wing flight. Cheli’s aircraft – a joint project between DigiSky and Turin Polytechnic University – is a two-seat Pioneer Alpi 300 with its conventional engine stripped out and replaced by a 75kW brushless motor powered by lithium-polymer batteries. SkySpark’s team says its electronic control systems are able to modulate motor speed and torque to provide dynamics that are far beyond what it is attainable from reciprocating engines.
