Water vehicle with a hydrofoil and additional second stabilizer

Abstract

The water vehicle with hydrofoil includes an above-water platform, a supporting mast connecting the above-water platform with a hydrofoil, including a fuselage with a front wing and a first horizontal stabilizer, drive means (6) for creating horizontal thrust and a second horizontal stabilizer located in the vertical direction between the fuselage and the above-water platform, where the second horizontal stabilizer in the longitudinal direction is being located behind the front wing. It is possible that the second horizontal stabilizer is mounted to the above-water platform, the mast, to the additional structurally supporting parts, to the parts that serve to change the angle of attachment of the main horizontal stabilizer, to the fuselage or drive means by means of a support element with the possibility of changing the vertical position.

1 . A water vehicle comprising:
 an above-water platform,   a hydrofoil comprising a fuselage with a front wing and a first horizontal stabilizer, and   a supporting mast connecting the above-water platform with the fuselage of the hydrofoil,   
       the water vehicle includes a second horizontal stabilizer located in the vertical direction between the fuselage and the above-water platform, wherein the second horizontal stabilizer, in the longitudinal direction, is located behind the front wing. 
     
     
         2 . The water vehicle according to  claim 1 , the second horizontal stabilizer being mounted to the water vehicle with the possibility of changing of the vertical position. 
     
     
         3 . The water vehicle according to  claim 1 , the second horizontal stabilizer being mounted directly or indirectly to the supporting mast. 
     
     
         4 . The water vehicle according to  claim 3 , the second horizontal stabilizer being mounted to the supporting mast by means of a support element. 
     
     
         5 . The water vehicle according to  claim 4 , the support element of the second horizontal stabilizer being a support beam which is attached to the supporting mast with the possibility of changing its vertical position. 
     
     
         6 . The water vehicle according to  claim 1 , the second horizontal stabilizer being mounted at a distance of at least 10 cm below the above-water platform. 
     
     
         7 . The water vehicle according to  claim 1 , the second horizontal stabilizer being located in the longitudinal direction between the front wing and the first horizontal stabilizer. 
     
     
         8 . The water vehicle according to  claim 1 , further including an underwater drive means for creating of horizontal thrust, and the second horizontal stabilizer being located in the vertical direction between the underwater drive means and the above-water platform. 
     
     
         9 . The water vehicle according to  claim 8 , the drive means including at least one electric motor with a water screw propeller, which electric motor is connected to a source of electricity.
