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.
