Your aircraft’s pyrotechnic systems must function reliably and efficiently. Keeping your equipment in working condition ensures that all essential ignition items and materials are ready for combustion. The primary aerospace components responsible for this task are bridgewire initiators. With high-quality exploding bridgewires for your aircraft, you can experience dependable ignition at all times.

AETC is your go-to original equipment manufacturer (OEM) for durable hot wire initiators tailored to your aviation needs. We’ve spent over 40 years producing safe and dependable devices for military, private and commercial clients.

What Is an Initiator?

Electric initiators are devices comprising pyrotechnic substances that produce heat or pressure to kindle materials that are traditionally difficult to ignite, such as thermal battery systems, gas generators, safety fuses and propellants.

Initiator compositions are similar to flash powers — however, they have a much higher production of hot particles and different burning speeds. These mixtures also exhibit easier ignition than other compositions, such as thermites.

How Do Bridgewire Initiators Work?

Aircraft initiators are controlled electronically by components called heated bridgewires. Bridgewires are thin resistance wires that set off pyrotechnic compositions. They typically use fuel and oxidizer solutions called pyrogen to promote material ignition.

Bridgewires are compact, lightweight and designed to optimize overall output and efficiency. They function similarly to detonators and blasting cups without producing shock waves. Instead, they create pyrotechnic compositions using exothermic chemical reactions.

Bridgewires reach high temperatures through the exchange of electrical currents. This heat initiates the attached substance’s exothermic chemical reaction. After the bridgewire fires, it melts and creates an open circuit.

What Are the Different Kinds of Hot Bridgewire Initiators?

There are many hot wire initiator configurations designed to accomplish different applications. These devices are available in low to high current ranges and fire and no-fire models. You can also find both single and dual bridgewire initiators with two-, three- and four-pin options.

What Are the Applications of Pyrotechnic Initiators?

Companies and organizations across numerous markets use pyrotechnic initiators in their fields, including military, commercial and private aviation industries. Since these explosive devices have many versatile features, professionals use them in dozens of industrial applications and equipment, including:

  • Aircraft seat ejection.
  • Oil and gas well perforation.
  • Solid rocket motor and thruster initiation.
  • Launch vehicles.
  • Aircraft fire extinguishers.
  • Separation mechanism actuation.
  • Satellites.
  • Missiles and munitions.
  • Propulsion system isolation valve actuation.
  • Demolition.
  • Parachute release.
  • Linear separation event initiation.
  • Electrical circuit breakers.
  • Nuclear weapon initiation.

When Do Bridgewire Initiators Require Replacement?

We recommend replacing your initiators on an interval that reflects your application, how often you use your equipment and other variables. For more information about creating a replacement schedule, contact the experts at AETC.
