Chinese engineers follow the Sea Dragon with new submersible that can ‘fly’ through water like a plane in the air
- Developers say their prototype craft could dive to 1,000 metres in five minutes
- Liu Kaizhou, who also worked the Jiaolong submersible, says ‘We are in uncharted water’
Chinese engineers say they are developing a radical design for a super-fast robot submersible which the project leader, who worked on the manned deep-sea vessel Jiaolong, or Sea Dragon, claims can “fly” in water like a plane travels through the air.
At 3 metres (9.8ft) long, the prototype consists of a cigar-shaped body, with a guidance system in the bow and a jet plane style rudder and a propeller in the stern.
Outriggers house batteries and two more propellers. These are attached to the body by wing-like planes that the developers said will give the vessel the kind of lift in water that takes an aeroplane into the air and back to the earth.
Developers said the prototype will be capable of 10 knots and could dive to a depth of 1,000 metres (3,281 feet) – or surface from that depth – at about three metres a second, taking about 5½ minutes.
Professor Liu Kaizhou, lead scientist of the project at the Shenyang Institute of Automation, part of the Chinese Academy of Sciences in Liaoning province, said the design had great potential.
