The invention provides a ground-effect wing ship with low takeoff resistance, and relates to the technical field of ground-effect wing ships. The ground-effect wing ship comprises an aero-engine and an air guide channel, an air inlet of the air guide channel is located behind the aero-engine, and an air outlet is located at the bottom of the bow of the ground-effect wing ship. The air guide channel guides part of wind power generated by operation of the aero-engine to the bottom of the ship, and in the floating navigation stage, air rushes out of the air outlet, so that the ground-effect wingship quickly enters the rising stage; in the rising stage, air gushing out of the air outlet moves towards the stern to form a bubble layer, water resistance is reduced, and the ground-effect wing ship can be accelerated to enter a high-speed sliding stage in a short distance; in the high-speed sliding stage, strong friction force is generated between the tail of the ground-effect wing ship and the water surface, aerodynamic lift is enhanced through air gushing out of the air outlet, the tail of the ship can be rapidly separated from the water surface, and the time for the tail to be subjectedto water resistance is shortened; in conclusion, the take-off time of the ground-effect wing ship is short, the resistance is small, and the problem that the take-off resistance of the ground-effectwing ship is large is effectively solved.
本发明提供了一种低起飞阻的地效翼船,涉及地效翼船技术领域。所述地效翼船包括:航空发动机和导风通道;导风通道的入风口位于航空发动机后方,出风口位于地效翼船的船头底部。导风通道将航空发动机运转产生的风力部分引导至船底部,在浮航阶段,出风口涌出空气,有助于地效翼船快速进入抬头阶段;抬头阶段,出风口涌出的空气向船尾移动,形成气泡层,减小水阻,有利于地效翼船在短距离内加速进入高速滑行阶段;高速滑行阶段,地效翼船的尾部与水面之间产生强大的摩擦力,出风口涌出的空气增强了气动升力,有助于船尾部快速脱离水面,减少了尾部遭受水阻的时间;综上,所述地效翼船的起飞时间短,阻力小,有效解决了地效翼船起飞阻力大的问题。
