Advanced Tactics Inc., a small aerospace company, released details about its AT Transformer vehicle technology and announced that a full-scale technology demonstrator has completed its first driving tests. The AT Transformer technology makes possible the world’s first roadable, vertical takeoff and landing (VTOL) aircraft. The patented AT Transformer technology combines the capabilities of a helicopter, such as the ability to take off and land anywhere, with the capabilities of an off-road automobile. The first technology demonstrator, the AT Black Knight Transformer, completed driving tests in December 2013 in Southern California and is scheduled to fly in early 2014.



Advanced Tactics began work on the AT Black Knight Transformer in 2010. The Black Knight Transformer is designed for autonomous casualty evacuation and manned or unmanned cargo resupply missions. Its unmanned capabilities keep pilots out of harm’s way, making it the safest casualty evacuation option. The interior volume is comparable to a Blackhawk helicopter, making it well-suited for cargo missions as well. In 2012, Advanced Tactics began work on the AT Panther Transformer, a similar vehicle designed specifically for Special Operations missions. It is a low-cost vehicle that carries two passengers and their gear, is transportable in a CV-22 Osprey cargo hold, and is operable with minimal training. This vehicle is shown below and will be used to transport passengers to a remote location that is inaccessible by traditional air or ground based means.

Imagine a situation where a soldier has been wounded on the front lines in an urban firefight – he’s being protected by the rest of his squad but he needs to be evacuated immediately or he will die. A nearby base is notified of the casualty and dispatches an AT Black Knight Transformer vehicle to evacuate him. The vehicle autonomously takes off and heads toward the front lines, 20 miles away. The squad is deep in the city and there are no safe landing zones within a half mile radius. Two members of the squad designate a safe landing zone in an open courtyard and wait for the vehicle there.

Once it arrives, it lands and the two soldiers climb inside. The flight engines are stowed and the vehicle enters driving mode. It is manually driven through the narrow streets to the casualty, who is quickly loaded onboard and connected to life support equipment. The vehicle is driven back to the courtyard where it takes off. Several minutes later the wounded soldier arrives at the base where he can be given full medical treatment within the “Golden Hour” after injury. The Black Knight Transformer’s unique air and ground ingress and egress options dramatically reduced the time needed to evacuate the casualty and his life was saved without risking a flight crew or the need for a ground transport.



The Black Knight and Panther Transformers both utilize the AT Transformer technology, which leverages the simplicity and robustness of a “multicopter” helicopter at a full-scale size. Like the small electric multicopters that are prevalent today, the AT Transformer uses engines with a direct drive connection to prop-rotors. The components of the propulsion system, including the engines and prop-rotors, are low-cost commercially available parts and the aircraft’s structure is made of modular field-replaceable components. Like an electric multicopter, the vehicle is stabilized and controlled by differential thrust between opposing sets of prop-rotors. This design is simple and robust, eliminating the mechanical complexity and cost of the articulated rotor system that stabilizes and controls a conventional helicopter and replacing it with a high-speed computerized feedback control system. Additionally, the configuration negates the need for a tail-rotor or engine transmission. The AT Transformer has the ability to perform controlled engine-out flight in case of a critical component failure.

The Black Knight and Panther Transformer vehicles have been developed through an iterative prototyping process starting with small scale electric prototypes and moving to the larger internal combustion powered technology demonstration vehicles. The first electric prototypes were flown in 2010 followed by a 2,000 lbs gas-powered vehicle in 2012, shown in Figure 6. A scaled prototype of the Panther vehicle has been tested and the full-scale version is in the early design phase.
