Lufthansa tests water-scavenger additive for fuel decontamination

提交时间:
 
Lufthansa is trialling use of a kerosene additive to remove water from fuel tanks on board aircraft. The "water scavenger" additive disperses water within the fuel, enabling removal of the contaminant from the system via the engine's combustion process. (www.flightglobal.com) 更多...

Pardon my ignorance, but do not large aircraft have sumps in the fuel cells to collect water and drain it easily? Checking for water in the fuel was one of the first things we did during a preflight inspection. Take 2 mason jars out to the bird, take a sample from each stub wing and spin it around. Water and any debris always settled at the bottom if it was in there. The pilots would check them on their way out to the bird for their preflight before we took off for the daily flights.

Still, I would want to see a sample before flight no matter what.

Not in jets. You’ll never see an airliner get sampled for water on normal operations. The fuel is screened by the fuel contractor for contaminants. The airlines fly so much that it’s really hard to have stagnant fuel. We fuel, takeoff, burn down to an hour or so of fuel remaining and then repeat. All while banking, pitching, etc. Very hard to get water in the fuel system in any measurable quantity.

Thanks, I was curious. At least the squadron I was in, we often had 4 or 5 flights a day for 5 hours a day and had to refuel twice, usually hot seating the PUI (pilot under instruction). We also hot refueled as well. Flying 5 days (2 nights) a week meant we used lots of fuel. I do not ever recall seeing any water in it either. Also, the birds always stayed fuel, just so condensation would not form in the fuel cells.
