Sikorsky S-92 Helicopter

     The S-92 is a medium lift helicopter designed by Sikorsky in 1995 for a number of roles, including executive transport, airline transport, EMS, Search-And-Rescue, offshore oil work, Heads-Of-State transport, and as a military helicopter (the Canadian CH-148 Cyclone) carrying 45 troops.  As an airline helicopter, the S-92 seats 19 passengers; when designed for executive and VIP transport, seats are reduced to nine, with a lavatory and a galley.  Armor is increased for both HOS and military roles.

     The helicopter burns 245 gallons of jet fuel per hour of routine usage.  A full tank of fuel costs $2,280.

 

Subassemblies:  Body +5, Top-and-tail rotor +1, six retractable Small Wheels +1.

Powertrain:  Two 2,043-kW Improved gas turbines; 4,086-kW Improved TTR drivetrain, 2,300-kWs advanced battery.

Fuel:  760 gallons jet fuel (Fire 13) in two light self-sealing tanks [Sponsons] (fire +0).

Occupancy:  2 RCS, 19 NPS or 9 RPS.

Cargo:  140 cf (2,800 lbs.) [Body].

Design Notes:

     Body is 1,375 cf; rotor is 27.5 cf; wheels are 68.75 cf.  Structure is light, standard with fair streamlining.  Armor is standard composite.  Mechanical controls.  Fuel tanks are light, seal-sealing.  Empty weight is 17,497 lbs.  Asking price for a 2001 model was $7,700,000.  Design aSpeed is 329; the real-world value is shown.  Design weight was 15% too low (but could readily change for alternate applications); real-world maximum take-off weight was used for all performance calculations.  Fly-by-wire electronic controls will be introduced in 2008.  Maintenance values were calculated from design cost.

 

Variants:

     None, except as redesigned for alternate primary roles.
