How Much Fuel Does a Fighter Jet Consume?

1 Answers

The fuel consumption of active fighter jets cannot be accurately calculated because factors such as flight speed, altitude, and intensity vary under different operational conditions, all of which affect fuel consumption. Fuel consumption of other aircraft: The Su-27 fighter has a maximum internal fuel capacity of 9.4 tons and a maximum range of 3,900 km. At a cruising speed of Mach 0.8, the Su-27 can fly for 4 hours, consuming approximately 2.35 tons of fuel per hour. The fuel costs for fighter jets are extremely high: The high fuel consumption of fighter jets poses a significant challenge to national military resources. Moreover, during missions, fighter jets often fly much faster than the speeds mentioned above, leading to even higher fuel consumption. Additionally, military aviation fuel prices are considerably higher than those for civilian use, further increasing costs. When factoring in aircraft maintenance and the various preparations required by ground support teams, the overall expenses become even more substantial.

Can Spark Plugs Affect Fuel Consumption?

Spark plugs do affect fuel consumption. If a spark plug is damaged, it can directly lead to increased fuel consumption in the vehicle. Methods to determine if a spark plug is damaged: Remove the spark plug and observe its condition based on the following appearance and color. A normal spark plug's insulator skirt and electrode should appear gray-white, gray-yellow, or light brown. A properly functioning spark plug's insulator skirt is reddish-brown, with an electrode gap between 0.8-0.9mm and no signs of electrode burn. If the spark plug has oil stains or deposits but is not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged, showing signs such as blistering at the top, black streaks, cracks, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plug with a new one. Additionally, if the spark plug appears black as if smoked, it indicates the wrong heat range was selected or the air-fuel mixture is too rich, with oil creeping up. Steps to replace a spark plug: Open the hood, lift the engine's plastic cover, and remove the high-voltage wires. Mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for external debris like leaves or dust and ensure everything is cleaned thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the high-voltage wires in the correct firing order and reattach the cover.
