Autonomous Firefighting Drone

Working with mentors from Sikorsky, three University of Connecticut engineering seniors are translating their classroom education to the field.

Electrical engineering majors Kerry Jones and Joshua Steil, and computer engineering major Ryan Heilemann, are collaborating to build and program an autonomous firefighting drone to battle blazes without a pilot's guidance.

“In the world today there's a high prevalence of forest fires, like in California, but the problem is of how to safely put out these fires,” says Steil. “So our project, in essence, is to see if we can start putting out fires without a human driver.”

Once finished, the drone will carry a thermal imaging camera to identify a fire, object avoidance technology to steer clear of any obstacles, and a softball-sized fire-extinguishing ball that will be dropped over the flames. The system's technology will be tied together through coding language developed by the students, and will operate based on inputted coordinates.

While their drone will only be able to put out a campfire-size blaze, the project is meant to prove that this technology is possible, so that much bigger technology can be engineered in the future, says Heilemann.

“The idea is that in the future, on a larger scale, there can be a fleet of unmanned helicopters that can go out and put out forest fires, thereby lowering loss of life,” says Steil.

While drones are currently used by fire departments across the country, all of them so far have a pilot who navigates the drone from a distance, and most are used for observation, not fire suppression.

“The autonomy definitely makes it different,” says Jones, “and the fire-extinguishing ball, for sure.”

Teams in previous years have worked on similar projects with Sikorsky, which provided some guidance on what has worked and what has not.

The team looked back on previous projects' reports, including last year's team, which was the first to integrate firefighting capabilities into the drone. While the previous team to work on this project used small thermal sensors called thermopile array sensors, Heilemann says these sensors required the previous drone to be only about six feet from the flames, which was too close for real-world applications. His team decided to use an infrared camera, which allows for more distance from the flames.

This year's team had the added benefit of working on their project in UConn's brand new 118,000 square-foot Engineering and Science Building, which features three engineering floors filled with faculty and labs focused on robotics, machine autonomy, and virtual and augmented reality.

At Sikorsky, the team is working with a recent UConn School of Engineering alum, Jason Thibodeau, deputy manager of Sikorsky's Flight Controls and Autonomous Systems Department.

“He's really helpful. We have phone meetings every Monday, and we tell him what's going on, what we're struggling with, and he reasons with us,” says Jones.

Adds Heilemann, “He really wants us to figure our way through issues we have, instead of just giving us a direct solution.”

Working with Sikorsky also introduced the UConn seniors to new career options. Jones has accepted an offer with Sikorsky after she graduates, in their autonomy lab as part of their Rotary and Mission Systems department.

Steil has accepted a job offer with Sikorsky's parent company, Lockheed Martin, in Massachusetts after graduation.

“Working with Sikorsky definitely sparked a greater interest looking into the company as a whole,” he says.

Heilemann also decided to go into the aerospace industry, and has found a job doing control and diagnostics at another aerospace company.

Most importantly, the collaboration was a chance to get some experience with a top company.

“In this project, I get to learn so much about Sikorsky and what they do,” says Steil, “and having a company like that so close to home and have them be our sponsor is definitely an added benefit.”

    Space Development Agency wants someone to launch its first 28 satellites

    Nathan Strout WASHINGTON — Now that the Space Development Agency has selected four contractors to build its first 28 satellites, the organization is looking for a launch provider to ferry them into orbit. According to a solicitation posted Oct. 6, the agency plans to select one company to provide launch services for all 28 satellites, with the first launch taking place in September 2022. Those 28 satellites will comprise tranche 0 of SDA's National Defense Space Architecture, a new proliferated constellation providing a whole host of services primarily from low Earth orbit. Among other things, the NDSA is anticipated to provide beyond-line-of-site targeting, hypersonic missile warning and tracking, and a space-based mesh network that will connect all of the services as part of the Pentagon's new Combined Joint All-Domain Command and Control (CJADC2) approach. The constellation will ultimately include hundreds of satellites, but SDA isn't putting them all up at once. Rather, the agency has adopted a spiral development approach, where the most mature and ready technology is added to the constellation in two year tranches. This launch solicitation covers the first tranche, otherwise known as tranche 0. Slated to go into orbit in fall 2022, tranche 0 is what SDA calls its “war fighter immersion tranche.” “Its goal is to provide the data in a format that the war fighters are used to seeing on tactical timelines that they can be expected to see once we actually become operational,” SDA Director Derek Tournear told C4ISRNET. “The whole purpose of tranche 0 is to allow the war fighters to start to train and develop tactics, techniques and procedures so that they can create operational plans for a battle where they would actually incorporate these data.” With just 28 satellites, tranche 0 will not provide global, persistent coverage. Instead, it will provide periodic, regional capabilities. Tranche 0 will feature the inaugural satellites in the transport and tracking layers. The 20 transport layer satellites will form the base of a space-based mesh network, passing data from satellites to weapon systems along a high-speed, on-orbit corridor. Tournear has previously stated that the transport layer will serve as the space component of CJADC2, the Pentagon's effort to connect sensors to shooters across domains and services. The inaugural tracking layer will be made up of eight satellites. The tracking layer will be used to detect and track hypersonic threats, working with the transport layer to pass tracking data and custody from satellite to satellite—collaborating to keep an eye on globe-traversing missiles that can evade current missile warning capabilities. SDA has selected Lockheed Martin and York Space Systems to each build 10 of the transport layer satellites, while SpaceX and L3 Harris will split the eight tracking layer satellites. Because the SDA has given vendors flexibility in the designs of their satellites, there is some variety to the weight of the space vehicles being launched into orbit. While all 20 transport layer satellites will weigh approximately 200 kilograms, give or take 20 kilograms, there is a significant difference in the size of the eight tracking layer satellites. One vendor—either SpaceX or L3 Harris—will be contributing four tracking layer space vehicles weighing approximately 1,068 kg each. The other vendor's space vehicles will be significantly lighter at just 249 kg. In total, SDA is looking to put as much as 10,164 kg of hardware into orbit. The agency wants all 28 satellites delivered to two circular, 950 km near-polar orbits, with the tranche divided evenly into two planes of 14 satellites. The launch provider has until March 31, 2023, to put all payloads on orbit and has discretion as to how many launches it will use to do that. The goal is to have as many satellites up as close to September 2022 as possible. Proposals are due by Nov. 5 at 4 p.m. EST. https://www.c4isrnet.com/battlefield-tech/space/2020/10/08/space-development-agency-wants-someone-to-launch-their-first-28-satellites/
