HONEYCOMB SCIENTIFIC SCREEN DEMONSTRATION*

Red yarn tufts in an air jet with and without a hex screen.


   Without Hex Screen                                                       With Hex Screen


-  The jet is directed upward and the yarn illustrates the reduction in rotational velocity.

-  80% of the rotational energy imparted by the prop is recovered and converted to thrust thereby compensating for the drag of the screens.
