Sikorsky and Rain demonstrated how an autonomous Black Hawk helicopter can be commanded to take off, identify the location and size of a small fire, and then accurately drop water to suppress the flames.

At the Sikorsky headquarters in Stratford, the Rapid Wildfire Response Demonstration showed the effective fusion of Sikorsky’s MATRIX flight autonomy with Rain’s wildfire mission autonomy system to suppress a fire in its incipient stage.

Representatives from NASA, Federal Emergency Management Agency (FEMA), Defense Advanced Research Projects Agency (DARPA), Los Angeles County Fire Department, Orange County Fire Authority, and the philanthropic and impact investment community witnessed the demonstration as part of a two-day wildlands firefighting meeting to discuss autonomy.

“Government agencies, aerial firefighting operators, and investors are coming together to learn and see how both flight and mission autonomy can help prevent high intensity million-acre wildfires,” said Maxwell Brodie, Rain CEO. “Wildfires cost the United States over $390 billion annually, and multiple risk factors are set to grow up to 30% by 2030. We look forward to demonstrating to lawmakers how autonomous aircraft can stop fires from breaking out, or continue the fight into the night, and in turbulent and smoky conditions, where crewed aircraft wouldn’t venture.”

During the 30-minute flight demonstration, guests used a tablet to command the Black Hawk aircraft to take off, search and find the fire, then drop water from a Bambi Bucket slung 60 feet beneath the aircraft. Each of three successive water drops extinguished a 12-inch diameter propane-fueled fire ring emitting a 3-to-6-inch-tall flame, demonstrating the precision of the Rain fire perception and targeting capability. The Rain system also rapidly adjusted the flight path to account for an 8-to-10-knot crosswind during each water drop.

Sikorsky safety pilots in the Black Hawk cockpit monitored the flight controls, but were hands-off until the aircraft landed.

“With Rain’s wildfire mission software loaded onto the aircraft and a tablet, wildland firefighters in the field could deploy autonomous Black Hawk or Firehawk helicopters to search and attack wildfires before they spread out of control,” said Igor Cherepinsky, director of Sikorsky Innovations’ rapid development/prototyping group. “Having worked closely together for over a year, our two companies are ready to demonstrate the joint capability in more dynamic conditions chosen by firefighters.”
