Wildland fires are currently destroying many natural forested areas of the United States. These huge fires spread over natural terrain very rapidly and are difficult to control because they occur in remote areas, often burning everything in sight. Many people have lost their mountain homes due to wildland fires, and firefighters are having a difficult time controlling the fires from spreading further during the hot summer months. One weapon used against wildland firefighters is the heavy air tanker aircraft. Air tankers are designed to carry heavy payloads and when air tankers are used in wildland firefighting, they are equipped to carry enormous payloads of water or fire retardant to the location of the wildland fire and then drop their payload on the area of the fire as they fly overhead. Air tankers are invaluable in the fight against wildfires and are in high demand during fire season.
Two companies, Thrush and Drone America, have teamed together to develop an autonomous air tanker that can be used to drop water and fire retardant on wildland fires while being piloted robotically. The autonomous air tanker is an enhancement of other drone-like aircraft currently in use by law enforcement and fire fighters. Current autonomous aircraft are used to monitor wildland fires from an aerial viewpoint, search for hot spots that may reignite, and photograph the spread of fires over time. Dropping a payload autonomously has significant benefits for emergency workers, however. Primarily, keeping pilots out of dangerous situations and flying over dangerous terrain is beneficial from a personnel standpoint. Also, autonomous aircraft have the benefit of being able to fly during the night time and navigate terrain successfully using onboard sensors. Since temperatures are usually lower at night, fires tend not to spread as quickly when the sun goes down, allowing autonomous air tankers to drop water and fire retardant on fires when they are less prone to spread. Plans for development are still under consideration, and teams from both companies are exploring other uses for autonomous aircraft as well.

Boeing recently unveiled a new prototype unmanned cargo drone that is currently under development. The drone, more appropriately called an unmanned aerial vehicle, or UAV, is being developed for use as a logistics operations support vehicle for the military and for commercial purposes. The drone will be electric powered and will be able to carry a 500 pound payload for cargo operations. Boeing is developing the drone as a flying test bed to be used during development of other concurrent projects including the passenger-carrying Aurora Flight Sciences aircraft that was recently transitioned into an unmanned aerial vehicle. Steve Nordlund, president of Boeing’s Horizon X, stated that, with this project, the integration of unmanned aerial systems must be developed with safety in mind, and stated that Boeing will be at the forefront of shaping the future of autonomous flight.
Boeing’s Horizon X led the development of the cargo drone with its newly acquired Near Earth Autonomy from Carnegie Mellon University’s Robotics Institute. Near Earth Autonomy is developing a software platform complete with sensory inputs that enable aircraft ranging from small sub-meter drones to full scale aircraft to inspect and survey terrain, buildings, and structures autonomously. The Near Earth software and sensors will be implemented on Boeing’s cargo drone to assist in navigation and sensory input. Boeing’s Near Earth Autonomy has already been implemented on full-size autonomous helicopters in partnership with the US Army. Integration of the autonomous systems into full scale aircraft for cargo purposes was also completed for the US Marines recently.
In addition to developing a cargo drone, Boeing will be continuing development of other autonomous flight systems with Aurora Flight Sciences, including a joint venture that is being developed with Uber to create a passenger specific autonomous flying vehicle that will be able to transport passengers from point to point.

The United States Marine Corps is working on a few autonomous aircraft projects to enhance their performance in the battlefield. These aircraft are being designed to drop off supplies and ordinance to troops while located in remote areas that are otherwise difficult to reach without the use of specialized piloting techniques. In recent demonstration flights, autonomous helicopters were able to successfully drop off supplies while located within a test area. The company that is working on the autonomous development, Aurora Flight Science, retrofitted a UH-1H helicopter with autonomous sensors and cameras as well as LIDAR radar in order to be able to fly autonomously. The UH-1H helicopter was first developed in the 1950’s and 1970’s as a general-use helicopter. The UH-1H was made famous during the Vietnam War and is still in use today for many purposes. The Office of Naval Research’s (ONR) Autonomous Aerial Cargo Utility System (AACUS) program is developing a flight apparatus that can be retrofitted to more than just UH-1H helicopters. The goal is to make an aircraft-agnostic system that can be used on multiple flight platforms and can be controlled by a simple tablet-based system on the ground by troop deployments. The ground-based control will be simple enough to use that it will not require any advanced training in order to call in for re-supply missions or other support.
Aurora Flight Science’s system allows for vertical flight aircraft to detect and identify multiple hazards in the flight path of the aircraft. After detection, the hazards can be safely avoided using the built-in computers that control the aircraft at all times. The Autonomous Aerial Cargo Utility System has transitioned to the final stages before being used in the field. The United States Marine Corps is now performing experimentation and potential acquisition on the system.
Autonomous Aerial Cargo Utility System is also developing a high-performance vertical flight system, named Orion that is capable of flying for approximately 100 hours with a payload of about 1000 lbs. This unmanned aerial vehicle will is being developed under a new contract with the military and will be suitable for deployment anywhere in the world.
