Airbus Helicopters H160
The Airbus Helicopters H160 represents a leap forward in medium twin-engine rotorcraft. Purpose-built to excel across offshore transport, emergency medical services (EMS), search and rescue (SAR), and VIP shuttle missions, the H160 combines innovative aerodynamics, next-generation avionics, and passenger-centric design. By leveraging advanced composites, Blue Edge rotor technology, and the Helionix flight-control suite, it delivers superior performance, reduced noise footprint, and lower operating costs than any helicopter in its class.
Airframe and Aerodynamics
Composite Fuselage and Structural Design
Airbus Helicopters engineered the H160’s fuselage around carbon-fiber reinforced plastic (CFRP) panels bonded to an aluminum-alloy frame. This hybrid structure cuts empty weight by roughly 200 kg compared with traditional all-metal designs, boosting useful load and fuel efficiency. Integral crash-resistant features—energy-absorbing landing gear struts, cabin floor beams, and longitudinal supports—enhance occupant protection in the unlikely event of a hard landing.
Blue Edge Main Rotor and Fenestron Tail
The H160’s main rotor uses five “Blue Edge” swept-tip blades. These composite blades exploit a thinner airfoil and optimized twist distribution to diminish vortex formation at the tip, slashing noise by up to 3 dB and cutting vibration levels nearly in half. Its 12-blade Fenestron® ducted-fan tail rotor further reduces acoustic signature, directs anti-torque thrust more precisely, and improves yaw control in hover and crosswind conditions.
Powerplant and Transmission
Twin Safran Arriel 2E Turboshaft Engines
Power comes from two Safran Arriel 2E engines, each rated at 1,021 shaft horsepower (shp) at takeoff. These engines feature redundant lubrication and double-channel FADEC controls for instant response and built-in gesture toward single-engine performance requirements. Full-authority digital engine control (FADEC) optimizes fuel flow, while automatic power margin management ensures stable operation during engine-out scenarios.
Main Gearbox and Fenestron Drive
A single-stage epicyclic main gearbox transmits power from both engines to the rotor head, incorporating life-limit-monitored planetary gears and real-time oil-condition sensors. The gearbox also drives the Fenestron tail via a high-efficiency shaft, minimizing transmission losses and maintenance interventions.
Avionics and Flight Control
Helionix Modular Avionics Suite
At the core of the H160’s digital backbone lies Helionix—a fully integrated avionics suite featuring four 12-inch high-definition multifunction displays. With synthetic-vision-augmented primary flight displays (PFDs) and map-centric navigation screens, Helionix delivers unprecedented situational awareness. Its modular electronic architecture supports mission-specific add-ons such as high-resolution infrared cameras, weather radar, and digital moving-map systems.
4-Axis Autopilot and Digital Flight Controls
The H160 boasts a four-axis autopilot—two collective-axis and two cyclic/aileron-axis channels—tied into three-axis stability augmentation. Pilots benefit from automatic hover-hold, coupled approaches, and terrain/obstacle-avoidance warnings. A dual-redundant Fly-By-Light backbone ensures lightning immunity and total electrical isolation between flight-control channels.

Cabin and Mission Configurations
Passenger Comfort and Layouts
The H160’s cabin—spanning 4.15 m in length and nearly 2.4 m in width—accommodates up to 12 passengers in high-density mode or six in VIP format. Panoramic windows flood the interior with natural light, while optional mood lighting and custom leather seating elevate the passenger experience. Removable sound-insulating panels and 18 dB vibration dampeners make long cruises remarkably quiet.
Mission Flexibility
- Offshore Transport: Integrated flotation gear, automatic life-raft release, and anti-icing rotor blades enable all-weather operations to platforms located over 200 nm offshore.
- Emergency Medical Services (EMS): Quick-release rear bench, dedicated stretcher mounts, in-flight ventilator power sockets, and a flat floor permit rapid reconfiguration for critical-care teams.
- Search and Rescue (SAR): High-intensity searchlights, loudhailers, rescue hoist with 270 kg capacity, and wide-angle thermal imaging cameras support pinpoint search in austere environments.
Operational Efficiency and Maintenance
Health and Usage Monitoring System (HUMS)
Airbus’s integrated HUMS continuously tracks gearbox temperatures, vibration signatures, and engine health parameters. Predictive analytics flag maintenance needs before they ground the aircraft, boosting dispatch reliability to 98 percent and reducing unscheduled removals by as much as 30 percent.
Maintenance Planning and Costs
Through condition-based maintenance (CBM), line-replaceable units (LRUs) swapped in under two hours and modular component design trim line and base maintenance man-hours by nearly 20 percent. Contracts for full-program “HCare” support can drive direct operating costs below €3,500 per flight hour, making the H160 one of the most economical medium twin helicopters available.
Safety and Comfort Innovations
Crashworthy and Impact-Resistant Features
Energy-absorbing seats certified to 18 G and a crush-resistant cargo floor help protect occupants during hard landings. Fuel cells are self-sealing and positioned within impact-resilient wheel wells, while the landing-gear shock absorbers attenuate vertical loads to below 6 G at maximum descent rate.
Noise and Vibration Reduction
The combination of Blue Edge blades and Fenestron tail, coupled with tuned-mass vibration absorbers in the mast and cabin frame, cuts external noise footprint by 50 percent and cabin vibration by 40 percent compared to legacy platforms. This quieter operation permits night flights over urban areas with minimal disturbance.
Conclusion
From its composite-rich airframe and Blue Edge rotor system to the Helionix digital brain and HUMS-driven reliability, the Airbus H160 sets new standards for versatility, comfort, and total cost of ownership. Whether flitting between offshore rigs, rushing medevac teams to remote scenes, or offering VIP clients a smooth, whisper-quiet ride, the H160 demonstrates the future of medium-lift rotorcraft has truly arrived.
