The company that developed an aerial ignition system that can be carried by a drone has introduced an improved model that can hold almost three times the number of plastic spheres.
The Ignis 2.0 made by Drone Amplified can be loaded with 400 to 450 spheres that ignite 30 to 45 seconds after being released from the drone. Their previous system, Ignis 1.0, carried 150 spheres. The new design is easier to maintain and can drop the spheres at up to four times the rate if desired, an increase from 30 to 120 spheres per minute. By using an Android app, the user can configure ignition spacing, number of ignition spheres, mission duration, and altitude.
Firefighters have employed the concept of using machines for aerial ignition for 40 to 50 years starting with an aerial drip torch suspended below a helicopter and later advancing to equipment installed in the open door of a helicopter.
Just before they are released, the spheres, which contain a chemical, are injected with a second chemical that causes them to ignite 30 to 45 seconds later. Aerial ignition allows prescribed fires or firing operations on wildfires to be ignited in areas that can be difficult for firefighters on the ground to reach safely, reducing their exposure to hazards. It can also ignite controlled burns more quickly than it can be done by personnel on foot, and at less cost than a helicopter.
The Department of the Interior began experimenting with drones for aerial ignition in 2017 and in 2018 began using a much larger aircraft, the Matrisse 600 that can carry up to 13 pounds. In August it was used to ignite a firing operation at night on the Inyo National Forest on the Springs Fire 13 miles southeast of Lee Vining, California.
According to Drone Amplified, the DOI just finished testing the new Ignis 2.0 in Arizona and ordered 20 for immediate delivery.
The Chief Engineer for Drone Amplified, Jim Higgins, was a mechanical engineering graduate student at the University of Nebraska Lincoln when he and others built the first drone to be used to ignite a prescribed fire at Homestead National Monument west of Beatrice, Nebraska. Drone Amplified is based in Lincoln, Nebraska.
