美国国防高级研究计划局(DARPA)宣布,他们正在开发一种新的技术,以减小未来海军和商用船只的摩擦阻力。长期以来,研究人员一直认为,在舰船螺旋桨桨叶周围的水流中增加聚合物或微型气泡,理论上能够减少80％的摩擦阻力。然而这一理论从未在实际的舰载系统上实践过。
The Defense Advanced Research Projects Agency (DARPA) announced that they are developing a new technology to reduce the frictional resistance of future naval and commercial vessels. For a long time, researchers have been convinced that adding polymer or microbubbles to the water flow around the propeller blades of a ship can theoretically reduce the frictional resistance by 80%. However, this theory has never been practiced on actual shipboard systems.
