About Irkut Aircraft & Fuel Consumption
Irkut Corporation (part of United Aircraft Corporation of Russia) produces advanced aircraft like the MC-21, a new-generation medium-range airliner, and the Yak-130 trainer/light attack jet. These aircraft vary significantly in their fuel requirements.
Factors Influencing Fuel Consumption:
- Model & Size: Larger MC-21 airliners consume more fuel per hour than the Yak-130 trainer.
- Passenger Load: More passengers and cargo increase fuel usage.
- Flight Distance: Long flights benefit from better fuel efficiency compared to short hops.
- Engine Efficiency: New-generation geared turbofans (MC-21) are designed for lower consumption.
- Fuel Type: Standard Jet-A/Jet-A1 are common, but biofuels are being tested.
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:
An Irkut MC-21-300 flying for 3 hours on Jet-A fuel at ₹95/liter:
- Fuel Used = 2600 × 3 = 7800 liters
- Total Cost = 7800 × 95 = ₹741,000
- CO₂ Emissions = 7800 × 2.50 = 19,500 kg
Note: Fuel consumption figures are averages. Actual values depend on route, payload, and operational efficiency.
