Make it streamlined. Attachment: The streamlined shape is rounded in the front and pointed in the back, with a smooth surface, slightly like the shape of a water drop. Objects with this shape experience the least resistance when moving in the fluid, so the shapes of cars, trains, aircraft fuselages, submarines, etc. are often made into streamlined shapes. It is an external shape of an object, usually showing a smooth and regular surface without large undulations and sharp edges. The fluid on the surface of streamlined objects mainly behaves as laminar flow, with some or a lot of turbulent flow, which ensures that the object encounters less resistance. Streamlining can be understood as the movement of surrounding air around an object. Streamlined objects are usually more beautiful and often appear in the appearance design of products, which can greatly increase the speed of ships. Streamlined refers to the shape with a rounded head and pointed tail, which is commonly known as a water drop shape. However, in reality, raindrops are not standard streamlined shapes, but rather elliptical. Streamlined shapes can receive the least resistance in the fluid, so even the cross-section of the aircraft wing is made into a quasi-streamlined shape (semi-streamlined shape), which can generate lift without increasing air resistance. So this streamlined style is widely used, hoping to help solve problems.
