H145 helicopter design
The H145 is an advanced version of the Eurocopter EC145, developed in association with Kawasaki Heavy Industries.
The new helicopter features an all-composite tail boom with fenestron shrouded tail rotor. It features new composite blades, duplex tail-rotor actuators and dual hydraulic circuits, along with a newly designed gearbox. The helicopter features all-composite structure and aerodynamic geometry. It also features a skid-type landing gear.
Cockpit and avionics of the H145
The helicopter features the new Eurocopter avionics suite with three to four large primary displays, and an enhanced human-machine interface (HMI). It has a digital four-axis automatic flight control system (AFCS) that enables the pilots to overcome even the most demanding helicopter operations and environmental constraints.
The crew alert system and exclusive built-in test capacity of the aircraft provide first-rate pilot assistance for handling failures, emergency management and troubleshooting.
The avionics include flight navigation display, vehicle monitoring display, vehicle management subsystem and two duplex aircraft management computers. Reference sensors, three inertial measurement units and two air data sensors are also installed.
The avionics further include two three-axis magnetometers, an integrated electronic standby instrument, fire extinguishing system warning and digital engine control systems.
H145 cabin details
The helicopter features a spacious cabin, which can either accommodate one pilot and ten passengers, or two pilots and nine passengers. It has a total cabin volume of 213,15ft3 and cargo volume of 6,04m3. Two hinged cockpit doors are provided and a sliding window.
