About Lockheed Martin (Sikorsky) Helicopters & Fuel Consumption
Lockheed Martin’s rotary-wing portfolio is led by Sikorsky, maker of widely used civil and military helicopters. Fuel burn varies by model, mission, and conditions. Use this calculator to estimate hourly fuel usage, operating cost, and CO₂ emissions for representative Sikorsky types.
What drives fuel consumption?
- Model & engine class: Light twins like the S-76 burn far less than heavy-lift platforms such as the CH-53K.
- Weight: Payload, fuel on board, and mission equipment increase power demand.
- Flight profile: Hover, climb, sling-load, and low-level operations consume more fuel than cruise.
- Environment: “Hot-and-high” density altitude reduces rotor/engine efficiency and raises burn.
- Fuel type: Most Sikorsky helicopters use Jet-A/Jet-A1 (civil) or JP-8 (military). Sustainable aviation fuel blends can cut lifecycle CO₂.
Formulas used
- Fuel Used = Burn Rate (L/hr) × Flight Hours
- Total Cost = Fuel Used × Price per Liter
- CO₂ Emissions = Fuel Used × Emission Factor (kg CO₂/L)
Example
Sikorsky S-92 flying 1.8 hours on Jet-A at ₹95/liter:
- Fuel Used = 900 × 1.8 = 1620 L
- Total Cost = 1620 × 95 = ₹153,900
- CO₂ = 1620 × 2.50 = 4050 kg
Notes: Burn rates are representative averages for planning/education. Actual values depend on configuration, maintenance, and mission profile.
