The Sikorsky S-76 Spirit is a multi-purpose medium-size commercial
helicopter. The S-76 is powered by two turboshafts, has a four-blade main and a four-blade tail rotor as well as a retractable landing gear.
The development of the machine began with Sikorsky in the middle of the
1970s. Target group were companies, which looked for a medium business helicopter, as well as the oil drilling industry. Sikorsky's development experiences from the UH-60 Black Hawkserved as the basis for the S-74 (later renamed S-76 Spirit in honor of the US Bicentennial). which was able to transport 2 pilots and 12 passengers, received first two Allison 250 C30 turboshafts with 478 kWeach. The prototype completed its first flight on March 13 1977.
The S-76A was the first production variant. The type achieved
1982several class records within the range climbing achievement, maximum speed and ceiling.
After the S-76A, the S-76 Mk II (1982), the S-76B in the year
1987with a top speed of 155 knots at sea level.
2005series was S-76C+ in production, which is equipped with Turboméca Arriel 2S1 engines with FADEC. Improved the cockpit was continued to equip with an EFIS suite from Honeywell. The tail rotor could be made quieter by modification. For comfort increase active noise and vibration dampers are used. The main rotor is now manufactured from composite materials.
January 3, 2006the certified S-76 C++ has the more efficient Turboméca Arriel2S2, an intake air filter, an improved and quieter transmissionas well as changes of detail at the interior equipment and electronics. Altogether for the machine 92 orders of (1/2006).

Sikorsky S-75: The Advanced Composite Airframe Program (ACAP) was an all-composite Sikorsky early LHX proof of concept aircraft. ;Sikorsky S-76 SHADOW : Boeing-Sikorsky MANPRINT study. The original concept of the LHX program was to produce a one-man helicopter that could do more than a two-man aircraft. The Sikorsky (S-76) Helicopter Advance Demonstrator of Operators Workload (SHADOW) had a single-pilot advanced cockpit grafted to its nose. The purpose was to study the MANPRINT or human engineering interface between the pilot and the cockpit controls and displays. The cockpit was the prototype of a single-pilot cockpit designed for use on the prototype RAH-66 Comanchearmed reconnaissance helicopter. The cockpit was designed so sensors would feed data to the pilot through helmet mounted displays. The MANPRINT study determined that single-pilot operation of the Comanche was unsafe, and would result in pilot overload. As result of this study, the Comanche was designed to be operated by a crew of two. [http://tri.army.mil/LC/CS/csa/aahist3.htm#LHX Historic US Army Helicopters] ]
The S-76 is in use around the world with airlines, corporations, hospital, government operators and, notably, the
