Underwater wings called hydrofoils help lift the sea glider, reduce drag and allow for a smooth ride above the waves.

被称为翼的下机翼可以抬升海上滑翔机，减少阻力，使其在海浪上方平稳飞行。

Take a hydrofoil to the sumptuous Peterhof Palace and Gardens complex which was created to rival the Palace of Versailles in France.

翼，前的彼得霍夫宫殿与花园建筑群当初兴建此宫是为了要与法国的凡尔赛宫分庭抗礼。

When it's time to take off, the hydrofoils retract and the sea glider won't fly within a wingspan of the water surface, benefiting from an aerodynamic principle called ground effect to glide along a cushion of air.

当起飞的时候，翼会缩回，海上滑翔机不会在面的翼展范围内飞行，这得益于一种叫做地面效应的空气动力学原理，即沿着气垫滑翔。
