Civil EC120 ® 002 EC 120 EC120 B EVERYTHING YOU NEED IN ONE HANDY LITTLE PACKAGE EC 120 003 The EC120 B, also known as the “Colibri” (Hummingbird), is a 1.7 ton, single-engine aircraft designed for mission flexibility. The only fully FAR/JAR 27 certified helicopter in its class, it features advanced technologies for simple, safe and cost-efficient operations, as well as easy maintenance. The EC120 B’s state-of-the-art ergonomic cockpit, complete with a dual LCD-screen vehicle and engine multifunction display (VEMD ®), greatly decreases the pilot’s workload, and its Turbomeca Arrius 2F engine offers very low fuel consumption. The helicopter's Spheriflex ® main rotor head, all-composite blades and Fenestron® tail rotor increase safety, simplify maintenance tasks, and reduce the noise level to 6.7 dB below ICAO limits, making the EC120 B by far the quietest helicopter in its class. The EC120 B can comfortably carry up to four passengers and one pilot, all on energy- absorbing seats. The wide cabin, generous visibility and large luggage compartment make this aircraft ideal for a variety of civilian and parapublic missions, including aerial work, law enforcement, training and passenger transportation. The simple design of the EC120 B offers a new maintenance concept specially adapted for modern light-helicopter operations. Most of the maintenance tasks can be performed by the operators themselves with a limited need for specific tools. This independent maintenance has considerably reduced the operating costs of the aircraft. 004 EC 120 Aerial Work The EC120 B plays a large role in the Aerial work sector, thanks to its dependability, efficiency, quietness, comfort and safety. -
A Novel Contactless Sensor for Helicopter Blade Motion In-Flight
Paper 46 TOWARDS A EUROPEAN HELICOPTER NOISE CALCULATION METHOD Marthijn Tuinstra, Jos Stevens, NLR – Netherlands Aerospace Centre (Netherlands) Nico van Oosten, Anotec Engineering (Spain) Herold Olsen, SINTEF (Norway) Abstract Helicopter noise is strongly dependent on flight conditions, exhibiting in addition a pronounced directivity, complicating noise modelling. In land-use planning, the current best practice stems from fixed-wing aircraft and follows a Noise Power Distance approach that is unsuitable to include these features. The European Commission commissioned the development a novel helicopter noise model to be eventually part of a public “European Environmental Model Suite for Aviation”. The model embodies a helicopter noise calculation method based on the current state-of-the-art. A clustering strategy has been used to represent the European helicopter fleet, thus avoiding the need for performing noise measurements on all types of helicopters. The method uses an empirical source model, with noise hemispheres to faithfully describe the noise directivity pattern. Emission characteristics of a helicopter type are described by a set of hemispheres measured for a range of conditions within the flight envelope. Atmospheric propagation effects are accounted for to evaluate the noise hindrance experienced on-ground. The latter is based on established public models for atmospheric propagation, ground reflection and surface impedance. 1. INTRODUCTION providing a robust alternative to the fixed-wing 1.1. Background aircraft approach of ECAC Doc 29 in terms of Helicopter noise emission is strongly dependent Sound Exposure Level (SEL), Effective Perceived on flight conditions and varies heavily with Noise Levels (EPNdB) or Maximum A-weighted emission angles. Currently used land-use Noise Levels (LA,max).
