High static thrust ducted fan.
12 years and up.
Compared to other fan systems which are mainly made for static thrust we have the advantage of high speeds.
The systems develop high thrust and amazing speed all while making an awesome sound in flight.
With 70mm 90mm 110mm and 120mm fans offered in a range of voltages you are sure to find the perfect steamfan for your airframe and battery requirements.
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.
A static thrust test rig for a ducted fan or ducted propeller design.
Powerfun edf 50mm 11 blades ducted fan with rc brushless motor 4300kv balance tested for edf 4s rc jet airplane.
The high pitch frequencies have been minimized in the design.
The design was modeled in catia v5 using a naca 0015 airfoil for the duct with a 2mm separation distance between the propeller.
Maxxair hvhf 12combo heavy duty cylinder fan with 20 foot vinyl hose high velocity portable utility blower exhaust axial hose fan 12 inch yellow.
The new fan has been developed to have a maximum efflux speed and static thrust.
For a 6 inch diameter to produce say 300lbs of thrust lifting man and 100lb machine you will need a 360hp powerplant.
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.
Powerfun edf 50mm 11 blades ducted fan with rc brushless motor 4900kv balance tested for edf 3s rc jet airplane.
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.
This makes a powerful and wide flying style possible with your model.
