Further contributing to operational safety are the rotorcraft’s high-set main rotor and tail boom, and the Fenestron® shrouded tail rotor.
A “maintenance-friendly” helicopter
Building on Airbus Helicopters’ extensive experience gained with the BK117/EC145 helicopter family, the H145’s maintenance procedures optimize the intervals between periodical inspections, ensuring increased availability and reduced operating costs.
The optional helicopter usage monitoring system (HUMS) keeps track of the engine’s health in accordance with usage conditions, resulting in further availability and enhanced cost-effective maintenance.
The H145 is always “ready for duty,” capable of being equipped with a modern mission management system for police operations.
Fast and reliable, the helicopter can rapidly transport up to 11 officers to the scene. It is likewise ideal for the transport of special police forces.
Primary roles include and patrol, surveillance, and rescue missions, supported by the roomy, flexible cabin, and installation of forward-looking infrared (FLIR) and daylight cameras that are controlled by an operator who also handles communications and data exchange with ground-based police resources.
Other equipment opportunities include a powerful searchlight, external hoist, and simultaneous external roping capability for two persons – one on each side. Equipment under development includes a tactical mission management system, connectivity features and an EOS (electro-optical system) digital camera.
Further contributing to the helicopter’s operational flexibility is its night vision goggle-compatible cockpit with a night vision imaging system (NVIS).
Emergency medical services
Building on the worldwide use of Airbus Helicopters’ H145 and predecessor BK117 in emergency medical services, the H145 is well tailored for primary/secondary missions and intensive care transport – benefitting from the easy and safe loading/unloading of patients through wide side sliding doors and the large rear clamshell doors.
Its spacious, unobstructed cabin was specifically designed to meet the requirements set by national medical regulatory agencies. The cabin accommodates one or two wheeled stretchers with partial or full suites of medical equipment for operation by up to three medical personnel.
The helicopter benefits from multiple EMS cabin interiors, which were designed in cooperation with one of the world’s leading EMS providers.
Comfort for both patients and the crew is ensured with the H145’s turbine-smooth ride. The helicopter’s extremely low external sound levels allow neighborhood-friendly operations around hospitals and in urban areas.
Offshore oil and gas transport
Long-range flight capability and the capacity to carry 8 passengers are attributes that make the H145 a natural for offshore oil and gas airlift missions.
Additional strengths include the helicopter’s high performance and small footprint. The H145 can operate in performance class 1 conditions, while its compact airframe can maneuver in the confined environments of oil/gas platform helipads.
The equipment list covers all elements required for offshore operations, including a color weather radar, emergency flotation system, helicopter emergency egress lighting (HEEL) and automatic deployable emergency locator transmitter.
Business and commercial aviation
The H145 brings together speed and comfort to create the optimum “time machine.” The spacious and flexible cabin can be outfitted with interiors that bring a touch of class for passengers – including the “Stylence” design developed by Airbus Helicopters for a highly functional work environment. A step higher in elegance is the leather and wood interior, designed by Mercedes-Benz.
As the quietest helicopter in its class, the H145 can land at work sites and in office zones and urban areas. It is one of the only aircraft authorized to fly in the Grand Canyon, along with the H135 and EC135.
Ample space is available for luggage, which is easily loaded through the rotorcraft’s rear clamshell doors. There is also an advanced in-flight entertainment systems and subtle ambient lighting.
The H145’s power reserves enable this helicopter to perform a variety of aerial work duties, facilitated by the wide cabin’s flat floors – which enable the loading of long and bulky goods – and the access provided through side and rear doors.
Among the utility applications is the servicing of offshore wind farms, which are being located increasingly farther out to sea – requiring the hoisting and hover performance provided by the H145.
Other uses include firefighting, the transfer of maritime pilots to arriving vessels and electronic newsgathering.
