# The Physics of Flying a Drone 190mph (record 2)

In my last post, I went through a lot of the physics of flying a drone at an average velocity of 90mph, which is close to the acceleration required to reach a final velocity of 190mph. The value is around 36.125 m/s^2 of ground acceleration to reach 190mph after 100mph flight.

To look at all the forces and kinematics of a record-breaking drone, you can refer to my last post

In all honesty, reaching an average velocity of 90mph and a final velocity of 190mph over 100 meters requires very similar physics, which is why I set those as my target speeds. That means that I can hopefully use the same drone frame and components to reach both records.

The graph of the velocity of the drone vs time, the integral of which is the displacement, and the derivative of which is acceleration.

Now that we have determined the net acceleration required, we must determine how we can reach this target. There are two forces acting in the linear direction. The thrust, and the drag. The thrust is provided by the motors, and the drag is created by air friction. In order to determine how powerful our motos must be and how much thrust they need to provide, we must figure out the drag force.

In the next article, I'll describe how I used SOLIDWORKS Flow simulation to find out the drag force of a drone in CAD software.
