The invention discloses an actual ship navigational speed and energy efficiency verification test method for an air layer resistance reduction system, an air layer resistance reduction system is additionally arranged on a ship to be tested, ship ballast water is adjusted in a first adjustment and navigation aid interval or a second adjustment and navigation aid interval, the ship is made to transversely incline in the direction opposite to the turning direction, the transverse inclination angle is larger than 2 degrees, and the ship can be subjected to actual ship navigational speed and energy efficiency verification test. And the ship can continuously heeling under the action of inertia during turning, the heeling angle of the ship is further ensured to exceed 2 degrees, and the air layer at the bottom of the ship is emptied, so that the opening and closing tests of the air layer resistance reduction system are alternately carried out. According to the invention, the actual ship navigational speed and energy efficiency verification test speed of the gas reservoir resistance reduction system can be greatly improved, the test time is shortened, inaccurate measurement data caused by sea condition change due to too long measurement time is avoided, and the accuracy of test data is ensured. Meanwhile, a large amount of test cost is saved.

    本发明公开了一种气层减阻系统实船航速及能效验证试验方法,待试验的船舶加装气层减阻系统,本试验方法通过在第一调整及助航区间或第二调整及助航区间调整船舶压载水,使船舶向转弯方向的反方向横倾,并且横倾角度大于2°,并通过转弯掉头时的惯性的作用,船舶会继续横倾,进一步确保船舶横倾角度超过2°,排空船底的气层,从而实现交替进行气层减阻系统的开启及关闭试验。本发明能够大幅提高气层减阻系统实船航速及能效验证试验的速度,缩短实验时间,以避免测量时间过长海况变化导致测量数据不准确,保证了试验数据的准确性。同时节省大量的试验成本。
