Helmets or all kinds of special helmet

These inventions concerns applications for lowering or increasing the turbulence or the flow resistance on objects.
 

  The following are specified here:
1. The positive sharkskin surface profile or the negative sharkskin surface profile,
 
 
 
 
 
 
 

2. The positive Lotus effect surface profile or the negative Lotus effect surface profile
 
 
 
 
 
 
 
 
 

3. The positive octopus compression suction cup surface profile or the negative octopus compression suction cup surface profile

These three surface profile types may be mounted on objects individually or in combination to one another as desired. Mounting solar cells on objects as desired is also of benefit for generating energy.



Figure 1

These pictures depict a model of positive sharkskin serving to reduce the flow resistance for the following technical applications or examples. Positive sharkskin produces a negative sharkskin with regard to the technical surface profile. The negative sharkskin is suited for reducing or increasing flow turbulence. While implementing positive sharkskin to decrease flow resistance a value of 3 to 18% can be attained. The negative sharkskin produces an increase or decrease in flow turbulence amounting to 2 to 18% on objects.




Figure 2

Figure 2 provides several illustrations of the positive lotus effect. The lotus effect (a surface resistant to collecting dirt) is based on hydrophobic tabular surfaces, which practically repel water and dirt particles. The positive lotus effect is suited best for reducing the flow resistance of objects located in water and for influencing flow turbulence, i.e. of turbine blades or turbine propellers of all types. In this respect a decrease of flow resistance by 2 to 8% has been attained on objects. The positive lotus effect as technical surface profile also produces a negative lotus effect. The negative lotus effect produces a favorable enhancement of flow turbulence and at the same time a turbulence harmonization, i.e. on the inside of turbines or all types of turbine vanes. In this regard an enhancement of flow turbulence amounting to 2 to 7% has been attained on objects.

The described negative lotus effect can also be implemented as additive in adhesives, bands, films of all types or in primary coats. The adherence, in other words the cohesion of the glued joints, increases in this case by approx. 8 to 15%, while in primary coats by approx. 4 to 12%.



 

Helmets or all kinds of special helmet

The individual attachment of a surface profile or the combination of this surface profile in the object application, e.g. as a positive sharkskin surface profile with its additional coating or in separate attachment through a positive lotus effect surface profile has the following, substantiated effects for:
 

Helmets or all kinds of special helmet.

The photo shows a sport helmet as an example of any kind of helmet which can be fitted with a positive sharkskin surface profile and/or a positive lotus effect surface profile to increase aerodynamics.

The helmet aerodynamics are increased by ca. 3 to 12 %.
