In our home we have an oily smut-like substance that reappers every 3-4 days we dont have any appliances that use natural gas. Our house is about 500 yards from a hanger where they put huge jet engines on racks bolted to the floor and test them. The exhaust is pointed directly at our home. I know they put additives in jet fuel to keep them from exploding so much in the event of a crash. If this additive doesn't burn during a crash, it might not burn in the engine. Could this be whats building up on the surfaces of our home. counter tops ect?
Not likely. What happens in the engine is that everything is burned at about 1800 degrees. The exhaust is very hot, dry air with a moderate soot content mixing with much cooler air after the burn, creating condnsation to form and travel with directionality. The soot mixes with the condensation forming an oily like substance. This is what you have on your home. You should consider putting up a tall fence in the direction where the exhaust is comming from. That would stop most of it from reaching your home. Although its not terribly dangerous on your house, its not the greatest stuff to be breathing in on a regular basis.
This is a tough one. First of all there are no additives in jet fuel. Commercial jet fuel is JT5 (also called JetA) which is basically kerosene. Second the combustion efficiency of the burner section in a jet engine is 99.99% so very little unburnt fuel goes out the exhaust. If jet engines did emit an oily residue then the runways at busy airports would be covered in no time and too slippery to land on. This is not the case. It could be possible that the engines are kicking up debris from the ground but before you go on the war path with the test area you might want to explore other possibilities.
maximum of you seem lacking an significant component - this is the action of blasting the nice and comfortable gasses out of the decrease back of the engine that creates thrust (Newtons's rules every person?!) If there is no exhaust eflux, then there is no thrust - and all you have is an high priced generator! it is the theory of a jet engine, and there is no escaping that. there is no accepted approach (at modern-day) of solidifying exhaust gasses, and if this way of mechanism replaced into ever devised it may require each aeroplane to be re-engineered. the place could you shop the waste components? What effects could the continuously changing mass have on the plane flying traits? How could you adapt the form? those are this type of concerns which you're able to could desire to evaluate. base line - advantageous theory, yet no longer achievable at modern-day and could grant no income. concerning rotating engines, maximum posters have already defined the drawbacks to that. maximum VSTOL plane rotate the exhaust nozzles to alter the path of thrust. The exception is the Osprey which as already reported, has rarely been a roaring fulfillment. to observe this theory to airliners could be high priced, impractical and inefficient. back, each little thing could could desire to be re-engineered to account for the greater beneficial weight that the mechanisms could upload. The wings would not be waiting to assist that variety of mass, after which you're confronted with having to re path gas lines, hydraulics, electrics and and so on. no longer trouble-free!
