After many incremental updates the Dauphin helicopter finally got a real successor in the 2010s, when Eurocopter announced the X4 design, that would eventually become the Airbus H160. While the H160 retained the basic appearance of the Dauphin, it has many typical features. First there is the side view silhouette, in particular the front. From the nose over the cockpit windows and the gearbox/engine housing to the rotor head is almost a straight line. The transition from cockpit front to side windows is quite sharp. The H160 has a main rotor has five blades with double swept tips: they look like sickles. Another first on the H160 is the canted shrouded tail rotor (fenestron). The same applies to the biplane horizontal stabilisers, that are connected at the tips. All-in-all, these characteristics make the H160 stand out from other helicopters.
Confusion possible with
The Aérospatiale Dauphin (the AS365N3 version is shown here) and the Eurocopter EC155 have the same basic appearance as the Airbus H160, but lack the key features of H160, like the sickle shaped main rotor tips, canted fenestron and biplane horizontal stabilisers.
The AW139 and AW169 are in the same class as the H160, but more of conventional appearance. So single horizontal stabilisers, an open tail rotor and straight main rotor tips.
The Airbus H175, with its waterhead appearance, is in some ways similar to H160, but also hasn't the typical H160 features. Moreover, the H175 has an open tail rotor.
