ESD Test Setup for Helicopters
MIL-STD-331C, NATO AECTP-250 ESD 300kV

Helicopters and aircrafts can be electrically charged by flying through the air and by collisions with rain or snow. Additionally rain drops and snowflakes can also generate damage and disturbance known as precipitation static (P-static).

Montena has developed a system for electrostatic discharges (ESD) up to 300 kV, to test personnel and helicopter borne electrostatic parameters according to MIL-STD-331C, MIL-STD-464A or NATO AECTP-250 leaflet 253. This test equipment simulates various parameters such as ESD from personnel to munitions, helicopter landing, in-flight refuelling and static precipitation. The equipment is built on two separate movable trolleys with the discharge electrode mounted on a piston which is adjustable in height and tilt.

Advantages

  • Multi-purpose movable test equipment on separate trolleys
  • Electrode adjustable in height (from 1 to 6 meters) and angle ( ± 60°)
  • Remote controlled operation for hazardous tests
  • Positive and negative polarity available
  • Pulse current measurement
  • Possible charging of the EUT with the electrode grounded
  • Computer controlled or manual operation
  • Additional P-static test setup in option
