Military Develops Unmanned Aircraft
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.
