The aerodynamics of flight
It's unpleasant to think about, but imagine what would happen if you were driving your car into a brick wall atВ 65 miles per hour 104 6 km per hour metal twist and tear glass would fly air bursts broke to protect you but even with all the security gains we have on our modern automobiles, it would probably be a difficult walk crash a car simply is not designed to go through a brick wall.
But there is another type of wall that cars are designed to move through, and have been for a long time - the wall of air that pushes against a vehicle at high speeds.
Most of us do not think the air or wind as a wall at low speed and days when it is not windy outside, it is difficult to notice the air mode of interaction with our vehicles, but at high speeds, and exceptionally windy days, air resistance, the forces acting on an object moving through the air - also defined as drag hasВ a huge effect on the way a car accelerates handles and achieves fuel consumption.
This where the science of aerodynamics comes into play Aerodynamics is the study of forces and the resulting motion of objects through the air source NASA For decades, cars have been designed with aerodynamics in mind, and vehicle manufacturers have developed a variety of innovations to cut through the air more easily wall and less impact on the daily conduct.
В Essentially, having a car designed with airflow in mind means it has less difficulty accelerating and can get better numbers of fuel economy because the engine did not work nearly as hard to drive the car through the wall of air.
Engineers have developed several ways to do this, for example, more rounded designs and outside the vehicle are designed to channel air in a manner so thВ to flow around the car with the least resistance can some high performance cars have even parts that move the air smoothly through the underside of the car Many also include a spoiler - also known as a rear wing - to keep air to lift the wheels the car and become unstable at high speeds Although, as you will read later, most spoilers you see on cars are just for decoration more than anything else.
In this article, we will examine the physics of aerodynamics and air resistance, the story of how cars are designed with these factors in mind and how the trend towards greener cars, aerodynamics is more important than ever.
