Airbus Helicopters H155

The Airbus Helicopters H155, originally launched as the AS365‑N4 Dauphin in 1977, is a medium‑weight, twin‑engine rotorcraft that has evolved through successive upgrades into a modern, high‑performance aircraft. Airbus Helicopters introduced the H155 name in 2015 to denote the latest generation, featuring advanced digital avionics, a five‑blade main rotor, and a spacious, climate‑controlled cabin that can accommodate up to ten passengers or a medical crew. Powered by two Turbomeca Arriel 2E engines, the helicopter delivers a maximum cruise speed of 260 km/h and a range exceeding 800 km, making it suitable for executive transport, offshore oil‑and‑gas support, and emergency medical services. Key innovations include the Helionix integrated flight control system, a glass cockpit with dual LCD displays, and an optional Fly‑by‑Wire flight‑control augmentation that reduces pilot workload and enhances safety. Since entering service, more than 500 H155s have been delivered worldwide, earning a reputation for reliability and operational flexibility. Its combination of speed, comfort, and cutting‑edge technology has solidified the H155’s role as a benchmark in the medium‑size helicopter market, influencing design trends across civilian and utility aviation. The H155 continues to set standards for future rotorcraft development.
