TITLE OF INVENTION: Helipads and heliports landing system

TECHNICAL FIELD TO WHICH THE INVENTION REFERS

Mechanical, Aerospace, Construction.

PRIOR STATE OF THE TECHNIQUE

The priority of each country to organize themselves properly in order to meet the mobility and infrastructure needs, combined with the lack of the current infrastructure system in responding to the changing mobility needs, have made increasingly urgent the use of helicopters as a transportation system for medium and large distances.

The use of the helicopter, however, is severely limited by the lack of adequate infrastructure dedicated, such as heliports and helipad, whose implementation is slowed by the process of design, approval and implementation of such infrastructures.

GOAL ACHIEVED BY THE INNOVATION

The goals that the innovation will achieve can be summarized as follows:

Build turnkey fully functional H24 helipad, with the integration of aeronautical lighting systems, in very short time and at a reasonable cost.

Extreme flexibility in the location and installation of heliports.

Reduction of the civil construction site activity interaction, compared to the helipads / heliports standard constructions methods (use of reinforced concrete, etc.).

Reduction of the bureaucracy compared to the helipads / heliports standard constructions methods.

Reduction of the environmental impacts.

BRIEF DESCRIPTION OF THE DRAWINGS:

The "Helipads and heliports landing system" is a device for the construction and development of helipads and heliports. The "Helipads and heliports landing system" consists of a set of aluminum profiles, with knurled surface, called Helinest 139, that gives the possibility in a few hours, with the aid of few skilled workers, to build turnkey fully functional helipad. (Fig. 8(a)), (Fig. 8(b)), (Fig. 9(a)).

HELINEST 139 - Ribbed profile

HNAR0816 profile. Is the main device and consist in a longitudinal hollow aluminum profile (Fig. 1(a)).

It is provided, on both side of the its length, with male (Fig. 1(c)) and female (Fig. 1(d)) cross section, that enable the connection between themselves (Fig. 1(b)). Head connection it is made by means of HNAI00605 (Fig. 3(a)) and HNAI00606 (Fig. 3(b)) special profiles, placed inside the cavity of the longitudinal profile HNAR0816 through a comb-graft subsequently fixed with steel rivets (Fig. 3(d)).

HNAI00605 cross male profile( /g. 3(a)). Used as said before, in couple with HNAI00606 (Fig. 3(b)), to connect, by their heads, the HNAR0816 profiles. HNAI00605 profile are placed inside the cavity of the longitudinal profile HNAR0816 through a comb-graft subsequently fixed with steel rivets (Fig. 3(d)).

HNAI00606 cross female profile( /g. 3(b)). Used as said before, in couple with H AI00605 (Fig. 3(a)), to connect, by their heads, the HNAR0816 profiles. HNAI00606 profile are placed inside the cavity of the longitudinal profile HNAR0816 through a comb-graft subsequently fixed with steel rivets (Fig. 3(d)).

HNAI00607 flat profile (Fig. 3(c)). This profile is placed into the slot created by the HNAI00605 and H AI00606 connection (Fig. 3(d)).

This profile is used to strengthen this connection. HNAI00606 sectional view show two vertical rails that improve its function.

HNAR0817 male-male profile (Fig. 5(a)). It connects transversely with the female side of HNAR0816 (Fig. 5(b)) main profile in order to reproduce the male cross section of the from the female side of the same profile.

HNAR0818 Ramp profile (Fig. 2(a)). It connects with longitudinally HNAR0816 directly or through interposed HNAR0817 or HNAR0819 profiles (Fig. 2(c)). The ramp profile complete the landing surface providing a link with the helipad ground foundation.

HNAR0819 special male profile adapter (Fig. 4(a)). It reproduce the male cross section of the HNAR0816 main profiles from their heads and can be used to make a T- connection with a same profile (Fig. 4(b)).

HNAR0816AVL profile - Derived directly from HNAR0816, with the addition of grooves and holes for the aeronautical light electric system integration (Fig. 6(a)), (Fig. 6(b)), (Fig. 6(c)). HNAR0816IR Profile- Derived directly from HNAR0816 with the addition holes for the helipad heating system integration (Fig. 7(a)), (Fig. 7(b)), (Fig. 7(c)).

ANALYSIS OF RESULTS

The "Helipads and heliports landing system", being a modular aluminum landing system, gives the possibility in a few hours, with the aid of few skilled workers, to build turnkey fully functional helipad, including additional aeronautical lighting systems totally integrated into the system.

The "Helipads and heliports landing system" can be installed on any ground surface, after a briefly preparation of the substrate with a limit of 5% slope.

The "Helipads and heliports landing system" is a profile that last. The spontaneous formation of an oxide layer protects the aluminum, making it particularly resistant to corrosion.

The "Helipads and heliports landing system" is an extremely innovative product with no impact on the environment.

The "Helipads and heliports landing system" pay particular attention to the environment: in fact the absence of activities typical of any other construction process and the use of a totally recyclable material such as aluminum allows the reduction of environmental impacts.

The "Helipads and heliports landing system" can be used both in the sanitary field for the realization of HEMS helipad and for private and business executives fields or in civil protection emergency situations. At the industry level it could be used effectively to implement quickly an infrastructure network of helipads.
