Fans and ventilators provides energy to the air by increasing its speed or pressure
the propellers of the aircraft or ship propellers, accelerate the fluid in which they move, the change in the momentum of the air or water generates the propulsive force by reaction on the propeller.
Index of the propeller and wing web site about propellers and wings calculation:
This natural object that is the propeller or wing,contains computational difficulties and design, which have to master, designers and engineering offices. Uncontrolled design of propellers or wing , may deteriorate the quality of the system created, wasting valuable energy and adversely affect the value of the project.. It would be a shame to stop, our creative energy to this technical obstacle, through lack of calculation method or information on the design of screw propellers and wings. The purpose of this site is to collect and make it affordable, design tools, and calculation for propeller and wingles allowing each to design the propeller or wing, best suited to his project.
This website is a support for propeller & wing design software: HELICIEL The tools and information provided here are within reach of the non-specialist.. It is understood that the design of aircraft and air transportation systems require mastery, Which is beyond the scope of this site, and remain under the competence, engineers supervised and trained in rules of safety! Hoping Heliciel.com is a useful link between your imagination and your project ...
The level of mathematics required to deepen theories of design propeller may be high enough to discourage those, who left the benches of the school long been, or who took more technical paths than theoretical.
This is why the purely mathematical aspects and methods of calculations of propellers, will be discussed algebraic methods for mathematicians desiring master them,
and more imaged for designers concentrated on the concrete realization of their propeller, wishing only to understand the principles guiding the design of propellers.
