article_snippet.sent: Nasa has unveiled a revolutionary type of wing that Nasa says could save millions in air travel.
article_snippet.sent: In this image, the technology is visible at the flat 'flap at the base of a flexible wing .
article_snippet.sent: Figures suggest The breakthrough could increase fuel efficiency up to 12 per cent, and reduce noise at take-off and landing up to 40 per cent, compared to traditional wing flaps (one shown on a Boeing 737) A Transformer-style ‘flying car’ being developed by an Arizona company could soon spell the end of runways.
article_snippet.sent: an Arizona company vision is to build a vehicle with four rotors that allow The company’s vision to take to the air anywhere like a helicopter - and then switch to fly like a normal plane.
article_snippet.sent: While this ‘SkyCruiser’ vehicle is still some way from development, the technology could soon become a reality in a functioning prototype dubbed the ‘SkyProwler’.
article_snippet.sent: SkyProwler has four horizontal propellers that allow SkyProwler to perform vertical take-offs and landings, and to hover in mid-air.
article_snippet.sent: the technology can be fitted to existing airplane wings, so the technology does not require a complete redesign of current aircraft wings.
article_snippet.sent: It will take years for such a technology to be approved for commercial aircraft, though, so
article_snippet.sent: It’s unlikely to be used on planes any time soon.
highlights_snippet.sent: Technology means that regular flaps aren't needed - and Technology is much lighter .
