Purpose of the development: Using the designed collector covers the outer surface of the aircraft ensures the reliability of flights in areas critical to lightning and makes a significant contribution to improving the life of all-weather operation of aircraft.

Recommended application field: Aviation equipment.

Advantages over analogues: - Circular knitted wire sizes and knit-soldered meshes more evenly distribute electrical charges compared with a rectangular cross-section of the structural elements stretch foil; - Elastic knitted mesh eyes ability to stretch without breaking; - A low melting solder, wire mesh covering, when heated evaporates and reduces thermal component of a lightning strike; - Elm-soldered structure promotes relaxation of mechanical loads and prevents significant stratification and destruction of the composite.

The development stage readiness: Introduced in production

Technical and economic effect: Through the use of polymeric composite materials (PCM), a saving of useful weight of modern aircraft, increasing the share of its operation and improve performance characteristics. The use of PCM and primarily CFRP over traditional metal alloys provides structural weight reduction of 20-40%, and increases the resource 1.5-3 times, reducing labor costs PA preparation production to 40% increase in the aerodynamic structure 1.5-2.

Description of the development:
()
Factors affecting the mechanism of energy dissipation using knit and knit-soldered grid: increased heat and the collector of the area struck by lightning; Wiring loops; evaporation from the surface of the solder wire and contact points of loops; Straightening wire loops; pulling the wire from the matrix. The polymeric matrix carbon nanoparticles create a percolation mesh and attach to the polymer conductivity. Depending on the type of nanoparticles (carbon nanotubes onionopodobnye particles and fibers), the percolation threshold can be in the range of from 0.001 to 10 wt.%. The electrical conductivity of composites filled nanotubes (5 wt.%), It has a value 0,00001- 0,01 S / m.
