Airbus Helicopters Applications. Applications Airbus Helicopters Technical characteristics of the Eurocopter EC 145

Recently the company Airbus Helicopters held an event at which it demonstrated a multi-purpose helicopter of the family H145(modification EC145/BK117). Today, about 1,000 of these models are in use around the world. Those gathered had the opportunity to communicate with the pilots, sit in the cockpit, and also watch the flight of this machine.

The modification of the EC145 multi-purpose helicopter was created as a result of a deep modernization of the VK-117S-1 helicopter and was originally designated VK-117S-2. The fuselage was almost completely changed and received a more streamlined shape. The nose section was redesigned taking into account developments from the EC135 model. This made it possible to reduce aerodynamic drag and improve visibility for the crew.
3.

The rear fuselage and cargo hatch doors have also been modified. The length of the fuselage increased by 20 cm. The helicopter received a more spacious cabin. The rear cargo hatch allows for quick loading and unloading of victims. At the same time, patients can be unloaded on stretchers safely even with the main and tail rotors rotating.
4.

Despite the fact that initially there were plans to equip the new modification of the EC145 helicopter with a tail rotor - a fenestron, after a series of experiments it was decided to leave the classic tail rotor. Later, on the new modification EC145T-2, the tail boom was modernized and equipped with a fenestron. Following the renaming and restructuring of Airbus, this family of helicopters received the designation H145.

If necessary, the helicopter cabin can be converted into a sanitary version within 20 minutes. For this purpose, a medical wall is installed in the cabin. Medical equipment is attached to it, which allows you to transport victims and maintain basic life functions. The cabin can accommodate two stretchers and three medical specialists. Good sound insulation and low vibration levels provide comfortable in-flight conditions for doctors to work, and patients - relative comfort during the flight.
8.

The cockpit has excellent visibility and comfortable ergonomics. Usually in this helicopter the pilot-in-command is located on the left. However, according to documents from the Moscow Aviation Center, the helicopter crew includes two commanders. The operating technology and the order of their interaction are described in the documents. The crew clearly knows who is responsible for what: who pilots, who communicates, who navigates, and so on.

The helicopter is controlled in roll and pitch by cyclically changing the angle of the blades. To do this, use the cyclic step control knob. Changing the lift of a helicopter is carried out by changing the overall pitch of the main rotor. To do this, use the “step-throttle” handle deflected upward under the pilots’ left hand. Yaw control is carried out by pedals.

The main task of the H145 family helicopter of the Moscow Aviation Center is to provide emergency medical care. These are mainly flights between accident sites and hospitals. Evacuation of injured and seriously ill patients.
14.

In total, the Moscow Aviation Center has 10 helicopters. Of these, five are H145 family helicopters, one Bell 429, three Ka-32, and one Mi-26. In 2016, 2,991 flights were carried out on board Airbus Helicopters aircraft operated by MAC and 821 victims were hospitalized. The flight time reached 1154 hours.
15.

To evacuate victims, pilots land near the accident. Assessing the situation and choosing a landing site in an urban environment is a difficult task. There are many factors here, and the main one is safety. Mostly you have to land on unprepared areas: parking lots, lawns, streets.
16.

After evacuating the victim from the scene of the accident, the helicopter is sent to the hospital. In Moscow there are 6 sites with equipment for landing helicopters day and night. These are the 7th city clinical hospital, the children's city clinical hospital named after Bashlyaeva, the Sklifosovsky Research Institute of Emergency Care, the 71st city clinical hospital on Mozhaiskoye Highway, the 15th city clinical hospital and the Yeramishantsev city clinical hospital.
17.

Flights are carried out over Moscow. The minimum altitude is 500 feet (150 meters). During the day this is a safe height. When flying by instrument in poor visibility conditions, pilots are required to climb to a minimum safe altitude. It is different for each sector of Moscow, but, as a rule, it is 1000 feet (300 meters).
18.

The multi-role helicopter of the H145 family can be modified depending on the field of operation: air ambulance, law enforcement, aerial work, passenger transportation, as well as transportation to an offshore drilling platform.

Eurocopter E.C.145 (after rebrandingAirbus Helicopters H145) - a medium twin-engine multi-purpose helicopter developed by the Eurocopter concern (Airbus Helicopters) in the late 1990s. It is used primarily as an administrative, police, and rescue and medical helicopter. The military modification is produced under the symbols or.

Story EC145

The EC145 was originally developed by Eurocopter and Kawasaki Heavy Industries based on the successful early BK 117 C1 helicopter. In order to save resources, the car was not created from scratch; in addition, a number of structural elements, as well as on-board systems, were transferred to it from another model - . In fact, the new helicopter was something between the BK 117 and EC135.

The prototype made its first flight in 1999 at the Eurocopter base in Germany. The new model was certified under the symbol BK 117 C2. In 1997, it was chosen by the French security forces as the main rescue helicopter. The first batch of 31 vehicles was delivered to the rescue fleet and replaced aging ones.

Eurocopter and Kawasaki had an agreement, according to which both concerns would be able to independently produce and sell helicopters on the world market, while development and modernization of the model range would be carried out jointly. However, some division of labor was established, with the Europeans producing the propellers, control systems, cockpit and tail components, while the Japanese supplied the fuselage components, transmission, some of the electronics and fuel system (a split roughly 60/40 in favor of Eurocopter). At the same time, it was decided to abandon the production of the Mitsubishi MH2000 helicopter. Thus, at the moment (2017), the EC145 is the only civilian helicopter produced in Japan. According to preliminary agreements, joint work on the machine will continue until 2025.

Description: EC145 helicopter arrival and landing

Design EC145

EC145 is a medium multi-role helicopter with a classic single-rotor design with a tail rotor, two turboshaft engines and a skid landing gear.

The helicopter has a larger cabin volume than the basic BK 117 C1. Also, with an increased take-off weight and new composite propellers, it has an increased flight range.

The power plant is two Turbomeca Arriel 1E2 or 2E turboshaft engines. Thanks to its high lift-to-drag ratio and advanced propellers, the EC145 is the quietest helicopter in its class (although it is not equipped with a Fenestron).

The helicopter is equipped with a glass cockpit developed by Thales Avionics. Thanks to high automation, the helicopter can be controlled by either two pilots or one. The EC145T2 model also has a FADEC engine control system.

As standard, the cabin accommodates up to 9 passengers, and the position and number of seats can be easily changed on the ground. Entry to the cabin can be through sliding doors on both sides or through a cargo door at the rear (for example, for medical helicopters). The medical version can accommodate up to two bedridden patients and two doctors.

Modifications

• EC145— basic model, originally called BK 117 C1. Equipped with Turbomeca Arriel 1E2 engines. Over time, the name when sold changed to EC145
• E.C.145 Mercedes— Benz Style — corporate helicopter developed by Eurocopter together with Mercedes-Benz. Designed to carry up to 8 passengers
• E.C.145 e — modification created to perform specialized tasks. Equipped with Garmin G500H interface. Rejection of a number of cockpit systems and elements made it possible to reduce weight and improve flight characteristics
• H145 — An upgraded version of the EC145, originally called the EC145 T2. The standard tail rotor is replaced by a fenestron. The engine was also replaced with a more powerful Arriel 2E (1039 hp)
• H145M- military version Originally called EC645 T2. Has armor elements, protected fuel tanks, detection systems, as well as mounts for weapons
• UH-72 A Lakota- military version created for delivery to the US Armed Forces

Law enforcement

The H145 is always ready and can be equipped with advanced command and control systems for a wide range of law enforcement operations.

Fast and reliable, this helicopter can quickly transport up to 9 personnel to the site of an operation, and is also suitable for transporting special police units.

This helicopter is primarily designed for patrol, surveillance and rescue operations due to its spacious cabin, forward-facing infrared cameras and daytime surveillance cameras, which can be controlled by the operator directly on board the helicopter without the need to transmit data through a ground control post.

The helicopter can also be additionally equipped with powerful spotlights, an external winch and rescue ropes for two people at a time from different sides of the cabin. A tactical mission management system, additional communications solutions and an electro-optical digital camera for installation on board the helicopter are currently being developed.

Additional operational flexibility is provided by the cabin's compatibility with night vision devices.

Air ambulance

Drawing on Airbus' extensive experience, the H145, like its predecessor the BK117, can be used for air ambulances to perform medical evacuations and transport intensive care patients thanks to simplified cabin access through wide side sliding doors or rear doors.

The spacious interior meets all the requirements of national medical authorities. The cabin can accommodate one or two wheeled stretchers, medical equipment and up to three medical personnel

The company has developed several interior options for medical transportation in collaboration with one of the world's leading air ambulance operators.

The comfort of patients and crew is ensured by the smooth running of the helicopter. In addition, the machine has incredibly low external noise levels and is ideal for use in urban areas.

Oil and gas industry and offshore work

Its long range and the ability to carry up to ten passengers make the H145 a natural choice for offshore transport for the oil and gas industry.

Other advantages of the helicopter are high flight performance and low noise levels. The compactness of the H145 allows it to maneuver even in the limited space of helipads on oil and gas platforms.

The list of installed equipment includes all the elements necessary for oil and gas operations, including a weather radar with a color display, evacuation lighting and an automatic emergency positioning transmitter.

Private and business aviation

The H145 combines comfort and speed. The interior of the spacious and functional cabin meets the expectations of the most demanding passengers. Airbus has specially developed the Stylence interior, which combines sophisticated style and work comfort. The leather interior with wooden elements from Mercedes-Benz will appeal to connoisseurs of elegance.

Through large cockpit windows, pilots and passengers can enjoy beautiful views overboard.

As the quietest helicopter in its class, the H145 can land in urban areas and office areas, getting passengers exactly where they need to go. This helicopter, along with the H135, is one of the few models that are allowed to fly at the Grand Canyon, USA.

Passengers will appreciate the spacious luggage compartment with easy access through the rear double doors, the in-flight entertainment system and ambient interior lighting.

Aviation work

The power of the H145 helicopter allows it to perform a range of aerial work. The flat cab floor and wide side and rear doors make loading and unloading oversized cargo easier.

The helicopter can also be successfully used to service offshore wind power plants, which are mainly located far from the coast and require the use of a winch and hovering mode.

Among other things, the H145 can be used for firefighting, transporting maritime pilots to incoming ships, as well as video and photography from the air.
