A British student developed a jetpack to swim fast underwater. The device is placed on the back like a backpack and pushes the swimmer forward with a pump. The engineer plans to present the serial version of the device in 2019, reports the 3D Hub company, which manufactured the parts of the backpack.
Normally, it is called jetpack (jetpack) to personal vertical takeoff and landing devices, which lifts a person in the air through a jet propulsion. Typically, these devices are created as unique models by enthusiastic engineers, but in recent years, several companies have launched small-scale jetpack series.
A student at the University of Loughborough (Archie O’Brien), used the same concept and created a jetpack to swim. Since the backpack does not have to cope with the weight of the body to move through the water, the jetpack was quite compact, similar to a conventional urban backpack. Most of the pieces of the apparatus were made in a 3D printer.
A pump that takes water in the upper part of the device and pushes it through two nozzles in the lower part responds by the movement of the backpack. The swimmer controls the speed of the device using a controller connected to the device by a cable. The backpack does not have a special turning mechanism, as it is sufficient to turn the body in the desired direction.
The pump in the jetpack allows the swimmer to move effortlessly up to 13 kilometers per hour. The engineer proposes to use the backpack not only for entertainment but also for rescue functions. The creator has already applied for the patent for the device, and in the second quarter of 2019 will present a serial model of the backpack.
