Euro Copter Develops a New Flight Guidance Concept and Russian Helicopters Go Naval.

Euro copter Has successfully demonstrated new landing procedures relying on augmented satellite guidance that can be tailored to more completely comply with the local environmental requirements. These new landing procedures were validated with a twin-engine Euro copter EC155 during flight tests performed as part of the company’s participation in the Green Rotorcraft Integrated Technology Demonstrator Program me-which is part of Europe’s Clean Sky Joint Technology Initiative. Euro copters validation flights demonstrated significant reductions in the helicopters perceived sound footprint-consistent with predictions. The company also confirmed that such automated low-noise approaches could be tailored to local environmental requirements, thereby optimizing Euro copter helicopter operations for even the most sensitive environments. The flight testing involved the use of optimized noise abatement flight paths compatible with Instrument Flight Rules (IFR) operations. During the EC155s landing approaches, vertical guidance was provided by EGNOS, the European satellite-based augmentation system (SBAS) ,with the helicopters flight management system (FMS) coupled to the automatic flight control system (AFCS).This enabled the new approach profiles to be flown accurately, minimizing the pilot workload with an automatic monitoring of speed profiles and ascent/ descent rates. “Improving the neighbor-friendly aspects of rotor craft continues to be a priority for us, and these new tests underscore how advanced flight guidance systems can be brought together with the latest navigation technologies to reduce perceived sound,” said Yves Favennec, Vice-President of Research at Euro copter. The Green Rotorcraft Integrated Technology Demonstrator Program me that supported Euro copters EC155 flight evaluations is part of the Clean Sky Joint Technology Initiative, which is Europe’s most ambitious aeronautical research programme ever. Clean Sky’s goal is to develop breakthrough technologies that significantly increase environmental performance of the air transport sector, resulting in quieter and more fuel efficient aircraft and rotor craft. Euro copter is a founding member of the Clean Sky Joint Technology Initiative, and recently joined with its other members to propose an extension of this effort during the 2014-2024 time period. Russian Helicopters Go Naval Nearly 460 companies from 36 nations took part in the recent International Defense and Maritime Salon (IMDS) exhibition in Saint-Peters burg, Russia, including 36 ships and other craft which were berthed or anchored at the nearby waterfront. The aviation part of the show included in-flight demonstrations by three Russian Air Force aerobatic teams. In addition, Russian Helicopters had two of its aircraft in the static display area for the first time, namely the ka-27PS SAR (used by the Russian Navy) and Ka-52 Alligator gunship of the Russian Air Force. The co-axis Kamov helicopter family is viewed as an ideal design for the ship-borne machines, with the result that many Ka-27/31 helicopters have been chosen by a number of navies outside Russia among them those of India and Peoples Republic of China. The Ka-52 had earlier made its international debut flying at the Paris Air Show before returning to Saint-Peters burg .The Maritime version, dubbed the Ka-52k,is to become a striking feature of the two Mistral –type LHDs-the Vladivostok and the Sevastopol-to be delivered to the Russian Navy by DCNS,of France ,in 2014-2015. The Ka-52k is going to be protected by a tough anti-corrosion coating and will be equipped with folding rotor blades and wings, as well as a number of systems adapted for naval use. The type is reported by Rosooboron-export, the Russian arms export state agency, to have already attracted a considerable amount of interest from a number of countries seeking to develop their naval power.
