EC- 135 helicopter combines Eurocopter's patented technology of low-noise ducted tail rotor. The ten blades of the propeller at the end of the duct are arranged asymmetrically at different intervals, which fundamentally reduces the noise of the helicopter. The main rotor is made of four blades, bearingless and high strength fiber composite materials.
The built-in anti-resonance isolation system also has a good effect on reducing vibration and noise level. As a civil operation mode, the external noise level of EC- 135 is 6dB lower than the specified level, and it is allowed to operate over large residential areas and hospitals.
EC- 135 is very popular in police enforcement because of its reliable double-engine design and low noise, such as Spanish police station; German Federal Border Police, Bavarian and Saxon Police; Travis regional police; Sweden, Ireland, Chile, Kuwait and Britain also have police departments. Helicopters are used for patrol, aerial surveillance, VIP and VIP transportation, and also play an important role in urban fire fighting.
McElpin Helicopter Company, founded in Oxford, England, equipped helicopters with police operating equipment and systems to meet the task requirements of the police department. A typical equipment includes a set of day and night monitoring pods under the fuselage, forward-looking infrared instruments, a set of multi-sensor turrets, SX- 16 searchlights, a loudspeaker system, a set of microwave sound and data downlink for safe communication, hooks, a rescue crane and medical evacuation components.
Options include providing a rape rope lowering system. Television and camera system can be installed in the engine room, and doors and observation windows for monitoring operation can also be installed in the engine room.
Rescue function
The German air rescue company uses search, rescue and emergency medical helicopters and uses them for service operations.
The emergency medical service helicopter is operated by one or two pilots. A helicopter can carry one or two stretcher patients, three doctors and some medical assistants. Install and equip different medical equipment as required.
The helicopter can be loaded and unloaded quickly and conveniently through the large sliding door at the side and the flap door at the tail of the helicopter. During the winch lifting operation, the patient can be quickly and safely transferred to the hovering helicopter. A load reflector and a set of double hook system installed outside the fuselage are used for patients, pilots and medical staff to cooperate with each other to ensure the safe and secure completion of rescue tasks.
passenger
The standard can carry drivers and six or seven passengers. The VIP/ executive type is suitable for four or five passengers. The helicopter cabin is convenient to get up and down, and the exit is equipped with a large sliding door. Baggage and cargo can be loaded through the flap door at the rear of the aircraft.
battlefield
The helicopter is equipped with SMD45 dual-screen flight and engine management system of Terez, avionics of Hanniwell Jinguan Company and AvioniqueNouvelle Company of Terez, aviation data computer, SFIM automatic flight control system, global positioning system and Hanniwell integrated flight data and cockpit recorder. A color weather radar system can be installed.
The EC- 135 helicopter used in the German Federal Border Guard is being equipped with the Hellas helicopter early warning system of the European aviation defense and space company Dornier. Hellas system was certified by Germany in June 2003. It is based on a lidar system. The Czech police helicopter has been equipped with the DK4 mobile map system of EADS/Dornier, which is very advanced in performance, and it is convenient for pilots to know their position and related information.
engine
Eurocopter provides EC- 135 with two engine types for customers to choose from, equipped with full digital engine control system. FADEC system provides enhanced performance, engine protection and power plant monitoring.
