About Sukhoi Aircraft & Fuel Consumption
Sukhoi aircraft are advanced Russian fighter jets used worldwide, known for agility, high speed, and powerful engines. Because of their large engines and supersonic capability, Sukhoi jets consume significant fuel, especially during afterburner use.
Factors Influencing Fuel Consumption:
- Model: Lightweight fighters like the Su-27 use less fuel than heavy multi-role jets like the Su-34.
- Flight Profile: Supersonic flight and afterburner drastically increase fuel burn.
- Payload & Weapons: Extra drag and weight increase consumption.
- Fuel Type: Primarily JP-8, though Jet-A and Jet-A1 are alternatives.
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:
A Su-30MKI flying for 1.2 hours on JP-8 fuel at ₹95/liter:
- Fuel Used = 10,200 × 1.2 = 12,240 liters
- Total Cost = 12,240 × 95 = ₹11,62,800
- CO₂ Emissions = 12,240 × 2.50 = 30,600 kg
Note: These are approximate values. Actual burn rates depend on altitude, mission profile, and use of afterburners.
