Abstract

Wynalazek dotyczy sposobu i ukladu redukcji oporu ruchu plynacych pojazdów wodnych z plaskim dnem poprzez wykorzystanie znajdujacej sie pod nim warstwy gazów. Pojazdy takie stosuje sie w zegludze sródladowej i morskiej. Zadania wynalazku to osiagniecie w miare mozliwosci równomiernego rozprowadzania warstwy gazów lub warstwy powietrza pod dnem pojazdu wodnego, redukcja strat gazu oraz wygladzenie przeplywu wody pod warstwa gazów w celu zmniejszenia oporu. W ramach sposobu proponuje sie przeprowadzenie w przynajmniej jednej komorze (5) przynajmniej jednego pierwszego pomiaru stanu wody L2 w przedniej i przynajmniej jednego drugiego pomiaru stanu wody L3 w tylnej czesci. Uzyskane sygnaly pomiarowe sa automatycznie porównywane, a w zaleznosci od otrzymanego wyniku porównania a) stan napelnienia cieczy w przynajmniej jednym zbiorniku przeglebienia (12) bedzie regulowany w taki sposób, ze bedzie regulowane przynajmniej pochylenie pojazdu wodnego wzdluz osi poprzecznej, i/lub b) przynajmniej jedno zamocowane na pojezdzie wodnym podwodne skrzydlo lub jego czesci bedzie/beda automatycznie przestawiane w taki sposób, ze pochylenie pojazdu wodnego bedzie regulowane przynajmniej wzdluz osi poprzecznej.The invention relates to a method and a system for reducing the drag reduction of a floating water vehicle with a flat bottom by using an underlying gas layer. Such vehicles are used in inland and sea shipping. The object of the invention is to achieve, as far as possible, even distribution of the gas layer or the air layer under the bottom of the water vehicle, reduction of gas losses and smoothing the water flow under the gas layer in order to reduce the drag. The method proposes to carry out in at least one chamber (5) at least one first water level measurement L2 in the front part and at least one second water level measurement L3 in the rear part. The obtained measurement signals are automatically compared, and depending on the obtained result of the comparison a) the filling level of the liquid in at least one trim tank (12) will be adjusted in such a way that at least the inclination of the water vehicle along the transverse axis will be regulated, and / or b) at least one the underwater wing or parts thereof mounted on the watercraft shall / shall be adjusted automatically so that the tilt of the watercraft is adjusted at least along the transverse axis.
