H145

The H145 offers exceptional performance thanks to its two Safran Arriel 2E power plants, each managed by a dual full-authority digital engine control (FADEC), along with the helicopter’s upgraded main and tail rotor systems. This guarantees an unprecedented level of performance in all engines operative (AEO) operations and vital power reserves in one engine inoperative (OEI) scenarios.

The H145 is the only rotorcraft of its range to take off and land at 20,000 ft – a distinction confirmed in September 2019 with a flight over Aconcagua in the Andes Mountain range (22,840 ft) – where the H145 demonstrated its incomparable power reserve at high altitude.

Twin-engine reliability is complemented by a fully separated fuel supply system, a duplex hydraulic system, dual electrical system and redundant lubrication for the main transmission. 

The H145 also is equipped with a wireless airborne communication server (wACS), allowing wireless data exchange with a ground station in the most secure way ever developed. The enabled data collection, exchange and analysis that are associated open a limitless world of improvement in the field of maintenance and flight management, further supported by the development of Airbus connected services.

As a further evolution of the BK117 family, the H145 incorporates the latest technologies, such as the advanced cockpit design with the most modern human machine interface (HMI), state-of-the-art Helionix® avionics suite and a Fenestron® anti-torque device as the tail rotor.

Airbus’ Helionix avionics suite offers undisputed superiority in flight envelope protection, pilot assistance, and data transfer efficiency. It enhances situational awareness by integrating innovative alerting and self-monitoring systems to provide unprecedented levels of flight safety.

Additionally, the H145 is equipped with an advanced dual-duplex, 4-axis autopilot specifically designed for helicopters. This offers:

• High flight stability and precision
• Unique flight envelope
• Over-limit protection
• Automated takeoff
• Fully-coupled approaches to hover

The H145’s shrouded Fenestron® technology brings benefits such as improved flight and ground safety to customers, as well as enhanced anti-torque control efficiency, reduced power demand in forward flight, and lower sound and vibration levels.

Customers benefit from simplified maintenance with the new advanced bearingless main rotor, which has fewer parts.

The simplified rotor system and airframe components, together with an enhanced main gear box, enable low maintenance costs and high in-service-time. The engines also significantly contribute to the reduced maintenance costs through high TBO (time between overhaul) and an evolved maintenance concept with usage monitoring, which increases engine availability.

The optional health monitoring system with 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.
