The systems develop high thrust and amazing speed all while making an awesome sound in flight.
High static thrust ducted fan.
Compared to other fan systems which are mainly made for static thrust we have the advantage of high speeds.
Thrust in lbs 9 35 horsepower x diameter of ducted fan in feet 2 3 power of 2 3 this is the formula i recall from the book.
Assuming you design your fan for high static thrust.
Static pressure for thrust fans is also assumed using an amca style a duct 0 5 of fan diameter for blade tip duct wall clearance for pressure fans and 1 of fan diameter for blade tip duct wall.

A ducted fan is an air moving arrangement whereby a mechanical fan which is a type of propeller is mounted within a cylindrical shroud or duct the duct reduces losses in thrust from the tips of the propeller blades and varying the cross section of the duct allows the designer to advantageously affect the velocity and pressure of the airflow according to bernoulli s principle.

The design was modeled in catia v5 using a naca 0015 airfoil for the duct with a 2mm separation distance between the propeller.
This supports up to 20 8 pounds per square foot of aircushion area or 101 6 kilograms per square meter unless otherwise stated a 0 5 in.
