Worldwide there are a few manufacturers, mostly in the USA, which produce and offer a similar landing and take-off areas, platforms or pads. Material of individual segments is mostly HDPE which is fairly expensive though.
Technical solution is such that all individual segments are firmly interlocked. As a matter of fact, such a solution is fine, however, the rigidity of the whole landing pad does not allow the reversible form deformation in the case of transverse or longitudinal forces. Those forces are commonly occurring during landing and touch down. Aircraft landing itself is basically a fall of the plane from a low height. Then the full weight of the aircraft is transferred through the wheeled chassis to the touch down points on the airfield in all diverse directions.
When helicopter of type M17 lands the three-point landing gear moves side-ways so that forces impact the airfields not only in vertical but also in horizontal transverse directions. Moreover, the landing in combat or even in training conditions is not always ideal. The helicopter pilot mostly executes the landing flying from certain direction so then adding the forward speed of helicopter it basically crashes into the airfield. As the individual segments are connected so that they are firmly locked, in these connections the landing impact leads to permanent deformation and damage of the take-off and landing area. Tiny partial damages are during further operation gradually even more degraded up to the moment when that take-off and landing area is not usable anymore. That system is more suitable for the civil sector with not very intense helicopter operations. Therefore it’s more suitable as a static parking stand of aircraft in order to prevent the damage to landing area ground. It requires a very careful treatment and maintenance.
As we know, the Air Forces of Czech Republic have purchased and used two such heliports made from segments of HDPE material with firm locking system but their experiences were not that positive due to above described issues and deficiencies. Because of the damages occurred those two heliports can be no longer used.
For these reasons we were contacted by our business partner who at that time was the sole supplier for Air Force of NATO member country with requirement to find simple and effective solution to the occurring problem. Our effort resulted in the portable heliport which we hereby present to you.
Our heliport was successfully tested in a variety of difficult heavy-duty conditions. Our product passed the defence standardization and codification of NATO.
Portable heliport which is built up from module parts garantees safe take off and landing of helicopter type Mi-17 outside the airport. Main utilization of such a heliport is for a missions when helicopter Mi-17 is operating out of the airport base or during a mission tasks of helicopter units.
The heliport is composed of interlocking module panels‘ system which creates a solid large area of 15x15 m. Each segment panel has the perimeter grooving system so that each panel interlock to each neighbouring one and thus they create solid linked hard cover of any surface.
