’s ability to integrate unmanned flight capabilities into its helicopter family has been validated by an optionally piloted vehicle (OPV) demonstration programme, which used an EC145 to fly routes that included deployment of an external sling load and a representative observation mission.
Conducted at the French Air Force base in Istres, France, this programme was revealed today with an unmanned demonstration, which followed similar flights performed earlier in April.
With this capability fully validated, Eurocopter is now positioned to pursue OPV flight capabilities for its product line of light, medium and heavy-lift helicopters – enabling these rotorcraft to be flown by pilots or in an unmanned mode.
“Eurocopter innovation is once again expanding the mission capabilities of helicopters, and we are ready to apply the proven optionally piloted vehicle competence in meeting customers’ needs,” explained Eurocopter Chief Technical Officer Jean-Brice Dumont. “This latest achievement results from our company’s expertise in flight control and autopilot systems, human-machine interface, system architecture and integration.”
Today’s unmanned demonstration – along with the previous flights– used a four-dimensional flight plan that was uploaded to the helicopter, with its starting and completion points situated on the Istres Air Force Base’s Runway 15/33. After an automatic takeoff, the EC145 flew the circuit via multiple pre-programmed waypoints, during which the helicopter performed a mid-route hover to deploy a load from the external sling. The EC145 continued on a return route segment representing a typical observation mission, followed by an automatic landing.
For delivery of the external load, the helicopter entered a planned hover – enabling the ground station controller to provide flight control inputs in orienting the EC145 over the drop point. The ground controller then transmitted a command to release load once the helicopter and load were correctly positioned.
The OPV flight capability was developed in an internally-funded Eurocopter programme, and was coordinated by a team at the company’s Donauwörth, Germany facility. Initial tests with a monitoring pilot aboard the EC145 were flown from Donauwörth and then at Istres.
The EC145 demonstrator is a Eurocopter testbed helicopter with an enhanced dual-duplex four- axis automatic flight control system (AFCS) and the latest navigation systems. In addition, the helicopter is fitted with the “plug-in” OPV avionics rack in its cabin behind the pilot seats, which contains the data link subsystems.
Visibility during the EC145’s unmanned flights was provided to the ground station via onboard cameras. They were complemented by an external gimbaled camera on the helicopter for infrared and daylight mission imaging.
Eurocopter’s OPV system was configured to enable uploading of the four-dimensional flight plans to the helicopter via data link from the ground station. The system included an automatic hover-to-land capability in case of major system degradation.
