SIKORSKY S-92 HELICOPTERTechnical Information

SIKORSKY S-92 HELICOPTERProgram StatusTECHNICALINFORMATION1Launched at the Paris Air Show in 1995, the S-92 has been developed to provide both civil and militaryoperators with the first true replacement for the S-61. From its inception, the S-92 was designed to provideunprecedented levels of safety, maintainability, reliability, and operational economics.Since its first flight in December 1998, the S/H-92 has accumulated over 1000 test hours in its developmentand certification program. The production configuration has been established with General Electric CT7-8engines and a Collins cockpit, and agreements have been signed with several commercial customers. BasicFAA Type Certification is scheduled for the fourth quarter of 2002. Expanded certification for specific customerrequirements will be completed in 2003, with production deliveries beginning in the third quarter.Parts manufactured by worldwide partners come together on the S-92 assembly line at Sikorsky’s Stratford, Connecticut facility.JANUARY 2002

SIKORSKY S-92 HELICOPTERComponent Overhauls and Retirement TimesTECHNICALINFORMATION17OVERVIEWMinimization of direct operating costs has, from the start, been established as a primary design criteria of theS-92 helicopter program. Projected DOCs have been continuously monitored during all phases of development.The underlying philosophy has been to reduce operator costs through the extension of component lives andminimization of the number of components subject to overhauls. As a result of holding to this philosophy, allcomponents on the S-92, with the exception of the main gearbox, require only on-condition maintenance.Themain gearbox itself has a TBO of 6,000 hours, higher than any gearbox previously introduced by Sikorsky intothe commercial marketplace.With the dramatic reduction in overhauls and life-limited components, the S-92 design will provide operators asavings in excess of 400 per flight hour in maintenance costs compared to any other-helicopter in the its class.The S-92 has only one component requiring scheduledoverhaul, and only two components with a retirement lifeof less than ten years or 12,000 hours.Unlimited life main rotor blade incorporates composite spar technology andutilizes a swept, tapered anhedral tip. This design provides improved lift andmaneuverability.Anti-torque control is provided by unlimited life tail rotor blades withbearingless composite flexbeam. The pitch control links use elastomericbearings.Designed to flaw tolerant certification requirements, the unlimited life S-92 main rotor head featuresredundant load paths and elastomeric bearings, The result is 50,000 hours before overhaul.JANUARY 2002

SIKORSKY S-92 HELICOPTERTECHNICALINFORMATIONCost of OperationOffshore Transport Service18The following information is supplied to aid in the preparation of estimates of the cost of operation for the S-92helicopter in offshore oil transport service. Costs have been calculated in general accordance with the practicesdescribed in the Guide For Presentation of Helicopter Operating Cost Estimates, published by the Committee onHelicopter Operations Cost. The estimates presume a mature operation in which there has been opportunity forcosts to stabilize and assume no benefit for warranties.Direct operating costs are calculated for a new S-92 flying 1,000 hours per year using 1999 prices. Reliabilityand maintainability characteristics are based on Sikorsky’s H-60 experience. The H-60 fleet has accumulated inexcess of 4 million flight hours since the model’s introduction in 1978. The S-92 design incorporates the lessonslearned on the H-60 program and thereby provides a significant improvement in cost-effectiveness.VARIABLE COSTSFUEL AND LUBRICANTSSIKORSKY ESTIMATEAverage fuel consumption (gallons/hour)Fuel cost per gallon ( )Cost for fuel ( /hour)Cost for lubricants (3% of fuel)178.01.51269.008.00Total cost for fuel and lubricants ( /hour)277.00LABORLabor rate ( /hour)Direct maintenance (MH/FH)Indirect maintenance (MH/FH)Total maintenance (MH/FH)Total labor cost ( /hour)JANUARY 200247.302.12.04.1192.00OPERATOR ESTIMATE
