Tentatively known as the S-76C++, the upgraded Sikorsky is powered by Turbomeca’s new Arriel 2S2 engine. The new engine promises 6 percent more power than its 2S1 predecessor, which currently powers existing S-76s. The initial 2S2 installation and testing on an S-76 prototype will start this month at the Pan-Uzein facility of Turbomeca subsidiary CGTM (Compagnie Generale des Turbo Machines). The new engine is equipped with a dual-channel Fadec.
