Category EN P19 Mimicking the Drag Reducing Qualities of Shark Skin

Abstract The goal of this science fair experiment is to design a shark skin

coating that can be applied to a rocket inorder to decrease the drag.

Everything used in the experiment will be either made or acquired at low

costs. A negative mold will be attempted to be made and then cast on to

the actual rocket using a resin. If that is unable to happen, then a product

designed to model shark skin will be used.

The method of measuring drag will be to place the rocket in a wind

tunnel and then calculate the force and coefficient of drag using the drag

equation. The rocket will also be launched and the maximum height will be

found and that data will be comparded. The hypothesis is that the modified

rocket will have a lower coefficient of drag than the unmodified rocket.

Estes model rockets will be used because they are premanufactured,

which will eliminate a variable. They also have parachutes that allow for

recovery after launching.

Many different conpanies and even the US Navy is doing research in

this feild of shark skin aerodynamics. Most have large budgets and are

testing laser inprints and UV drying paints.
