现在的轿车经常时速已达100 km 左右,最高时速更达200 km 以上,因此轿车的车身设计既要服从空气动力学,要有尽量低的空阻系数,又要采取措施,在车身的前后端安装导流板和扰流板,以保证轿车的行驶安全.在空气动力学上,有法国物理学家贝尔努依证明的一条理论:空气流速的速度与压力成反比.也就是说,空气流速越快,压力越小;空气流速越慢,压力越大.例如飞机的机翼是上面呈正抛物形,气流较快;下
Now the car often has a speed of 100 km per hour, the maximum speed of up to 200 km or more, so the car’s body design is subject to aerodynamics, to have a low air resistance coefficient, but also take measures to the front and rear ends of the body The installation of spoilers and spoilers in order to ensure the safety of cars in the aerodynamics, the French physicist Bernhard proved a theory: the speed of air flow velocity and pressure is inversely proportional to That is, the air velocity The faster, the less pressure; the slower the air flow, the greater the pressure. For example, the aircraft wing is a positive parabolic top, fast air flow; under
