Fly-by-wire

A technology kit developed by Sikorsky, a Lockheed Martin company, was used for the first time to operate a Black Hawk helicopter with full-authority, fly-by-wire flight controls. The May 29 flight marked the official start to the flight test program for the soon-to-be optionally piloted aircraft. Follow-on flight testing aims to include envelope expansion throughout the summer leading to fully autonomous flight (zero pilots) in 2020.

«This technology brings a whole new dimension of safety, reliability and capability to existing and future helicopters and to those who depend on them to complete their missions», said Chris Van Buiten, Vice President, Sikorsky Innovations. «We’re excited to be transforming a once mechanically controlled aircraft into one with fly-by-wire controls. This flight demonstrates the next step in making optionally piloted – and optimally piloted – aircraft, a reality».

This is the first full authority fly-by-wire retrofit kit developed by Sikorsky that has completely removed mechanical flight controls from the aircraft.

Through DARPA’s Aircrew Labor In-Cockpit Automation System (ALIAS) program, Sikorsky is developing an OPV approach it describes as pilot directed autonomy to give operators the confidence to fly aircraft safely, reliably and affordably in optimally piloted modes enabling flight with two, one or zero crew. The program aims to improve operator decision aiding for manned operations while also enabling both unmanned and reduced crew operations.

Sikorsky has been demonstrating its MATRIX Technology on a modified S-76B called the Sikorsky Autonomy Research Aircraft (SARA). The aircraft, which has been in test since 2013, has more than 300 hours of autonomous flight.

Sikorsky announced in March that its S-92 helicopter fleet update will include the introduction of phase one MATRIX Technology that will bring advanced computing power to the platform. This foundation enables adoption of autonomous landing technology.

First-Of-Its-Kind

U.S. Army pilots exercised supervised autonomy to direct an Optionally-Piloted Helicopter (OPV) through a series of missions to demonstrate technology developed by Sikorsky, a Lockheed Martin company and the Defense Advanced Research Projects Agency (DARPA). The series of flights marked the first time that non-Sikorsky pilots operated the Sikorsky Autonomy Research Aircraft (SARA), a modified S-76B commercial helicopter, as an OPV aircraft.

«Future vertical lift aircraft will require robust autonomous and optimally-piloted systems to complete missions and improve safety», said Chris Van Buiten, vice president, Sikorsky Innovations. «We could not be more thrilled to welcome Army aviators to the cockpit to experience first-hand the reliability of optimally-piloted technology developed by the innovative engineers at Sikorsky and DARPA. These aviators experienced the same technology that we are installing and testing on a Black Hawk that will take its first flight over the next several months».

SARA, which has more than 300 hours of autonomous flight, successfully demonstrated the advanced capabilities developed as part of the third phase of DARPA’s Aircrew Labor In-Cockpit Automation System (ALIAS) program. The aircraft was operated at different times by pilots on board and pilots on the ground. Sikorsky’s MATRIX Technology autonomous software and hardware, which is installed on SARA, executed various scenarios including:

  • Automated Take Off and Landing: The helicopter autonomously executed take-off, traveled to its destination, and autonomously landed;
  • Obstacle Avoidance: The helicopter’s LIDAR and cameras enabled it to detect and avoid unknown objects such as wires, towers and moving vehicles;
  • Automatic Landing Zone Selection: The helicopter’s LIDAR sensors determined a safe landing zone;
  • Contour Flight: The helicopter flew low to the ground and behind trees.

The recent Mission Software Flight Demonstration was a collaboration with the U.S. Army’s Aviation Development Directorate, Sikorsky and DARPA. The Army and DARPA are working with Sikorsky to improve and expand ALIAS capabilities developed as a tailorable autonomy kit for installation in both fixed wing airplanes and helicopters.

Over the next few months, Sikorsky will for the first time fly a Black Hawk equipped with ALIAS. The company is working closely with the Federal Aviation Administration to certify ALIAS/MATRIX technology so that it will be available on current and future commercial and military aircraft.

«We’re demonstrating a certifiable autonomy solution that is going to drastically change the way pilots fly», said Mark Ward, Sikorsky Chief Pilot, Stratford, Conn. Flight Test Center. «We’re confident that MATRIX Technology will allow pilots to focus on their missions. This technology will ultimately decrease instances of the number one cause of helicopter crashes: Controlled Flight Into Terrain (CFIT)».
