Aquaskipper
An Aquaskipper is a muscle-powered vehicle . According to the hydrofoil principle , you can glide over water and reach a speed of 27 km / h.
history
The principle of the Aquaskipper was invented in 1988 by the Swedish engineer Alexander Sahlin. In 10 years of work he had developed the first prototype, patented as a trampofoil . Through further developments ( fiberglass spring on the fork) by Chen Shane, President of Inventist , the series-compatible Aquaskipper was created.
construction
The design aims for the lowest possible loss of operation. The device is made of aluminum and composite materials and weighs 12 kg.
Basically, the sports equipment consists of two spring-connected T-pieces (crossbar = wings of the wings, see illustration). The lift is mainly generated by the flow of water over the rear wing (244 cm wingspan). Propulsion comes from sliding up and down when jumping. The front wing can be rotated using the linkage like a bicycle handlebar and serves as a steering and stabilizer.
Types of water
Practically all types of water are navigable, whereby low waves do not disturb, white water (surf) is unsuitable because of the lack of load-bearing capacity. The Aquaskipper can be used on lakes, rivers and in the sea. The water depth should be more than 100 cm (at takeoff), while the wings slide about 15–30 cm below the surface of the water.
business
It is operated by a rhythmic rocking movement. The athlete stands on two small kicks on the rear frame. The start is best from a jetty. To do this, the rear fin is positioned just above the surface of the water, one foot is already on the standing surface of the Aquaskipper, with the other you push yourself off the jetty and begin the rhythmic up and down movement. It is important to have a combination of “hopping” and pressing the arms synchronously. The best way to initiate a turn is to steer while at the same time shifting your weight outwards. You should increase the hopping movement a little before or in the curve. Starting from the water is not possible with the devices currently available. The average operating time of muscle-powered sports equipment is estimated at a maximum of 30-40 minutes for trained athletes.
