Eco Factor: Zero-emission demonstration helicopter powered by electricity.
The concept of a full-sized electric helicopter has been floating around for years, but the weight of the batteries and their low capacity has always ruined the idea. Recent advancements in battery technology has resulted in the development of next-gen batteries that are lightweight and energy dense. Sikorsky believes that time has arrived when these batteries can be used to power helicopters.
The company has announced the development of Project Firefly – an all-electric helicopter that has been based on the company’s S-300C trainer. The Firefly replaces the original 190hp 4-cylinder gas engine with a 200hp electric motor powered by lithium ion batteries.
The helicopter will be unveiled at the EAA Airventure in Oshkosh as a technology demonstrator designed to enable manned flight of an electric helicopter. Featuring a re-designed cockpit display, the electric helicopter can fly for just 15 minutes.
