2007-09-09 - Hellas for NH90First flight tests with the EADS obstacle warning system for NH90 successful

EADS testet HELLAS für NH90<br /> EADS Defence & Security has successfully tested the military version of the HELLAS (helicopter laser radar) obstacle warning system in flight.

The equipment known as the Military Obstacle Warning System (MilOWS) is being developed for deployment on the NH90 helicopter. As the company announced, the EADS Defence Electronics business unit has carried out the first flight tests with MilOWS on board the HELLAS demonstration helicopter for certification and as the basis for the approval of different helicopter types following the successful development phase. During these tests, the functionality of the equipment and the performance of the sensor were verified under flight conditions as required by the customer. Various obstacle scenarios were flown, including low level flights and spiralling at a roll angle of up to 45°. MilOWS detected the obstacles as expected. The good test results approve the work done by the developers so far as regards the design of this very complex optronic system. The data recorded during the flight tests serve to verify and optimise the algorithms for recognising and classifying obstacles in accordance with military requirement profiles. Further flight tests with this demonstration system are planned for October/ November 2007 in even more complex obstacle scenarios, such as military flight profiles.
During the completed development phase, MilOWS equipment was tested for several months in the NH90 integration rig at the premises of the company Eurocopter in Ottobrunn (Germany). All the interface functionalities with regard to the NH90 system were demonstrated with both pilots and customers being involved. The current version of the MilOWS worked perfectly. Likewise, the preliminary work for the mechanical integration of the obstacle warning system into the NH90 helicopter was carried out successfully at Eurocopter. The basis for qualification in the NH90 system has been created by these important milestones for the integration of the MilOWS obstacle warning system into the NH90 helicopter and the performance of the current test flights.
