Lighting generator to test aircraft safety

Project Detail

ICAR capacitors equip an innovative lightning generator to test aircraft safety.

CUSTOMER NEEDS

The customer is an important university that has designed and realized a system to reproduce the atmospheric discharges that aircraft must endure according to the standards for civil and military airplanes (ED-105 – Aircraft Lightning Test Methods; ED-84 – Aircraft Lightning Environment and Related Test Waveforms Standard; DO-160F – Environmental Conditions and Test Procedures for Airborne Equipment; Stanag 4236 Annex C), as shown in the table below. The primary function of this system is to verify the response of modern compound aeronautic materials to direct lightning strikes.

ICAR SOLUTION

For this application ICAR has supplied two capacitor typologies for use in continuing current: 75kJ and 50kJ each. They have been assembled in two benches with which the currents are produced in accordance with curves B and C, which are applied after curve A, supplied from an existing bench. The supplied capacitors have high energy density (J/dm³); this permits the realization of a reduced size system that is easily transported to the structures and materials manufacturers’ locations. The necessary strength to withstand the electrodynamic stresses of these discharges (at least 1000 strikes are guaranteed) and the transportation stresses are ensured from ICAR’s experience in the field of quick-discharge capacitors.

ADVANTAGES

  • Possibility to simulate lightning with high current
  • Transportable by third parties
  • System strength and stability
