Kingtech K140E testing
I tested my new K140E today on kero and diesel. This is what the numbers were. Very interesting.
Diesel idle 528c PW 056 Thrust 1# 4oz full 614c PW 261 Thrust 25# 14oz Kero idle 534c PW 055 Thrust 1# 2oz full 612c PW 268 Thrust 25# 10oz So I lost about 17.33% at 7400 ft alt that is real good most lose around 20 to 24% difference between kero and diesel is 1% George |
RE: Kingtech K140E testing
No much difference between the 2 fuels. I just wonder if the diesel will crap up the internals quicker than Kero.
Did you add oil to the diesel? |
RE: Kingtech K140E testing
Is that 25 lbs at full power ?
|
RE: Kingtech K140E testing
You get more power with diesel, this is why im going to give diesel a try plus its much easier to get. I bet at sea level it would pretty good.
|
RE: Kingtech K140E testing
25 lbs at full power but at 7100 above sea level! You would have a hard time breathing at that altitude if you were not accustomed to it.

RE: Kingtech K140E testing
When I get mine running next weekend I will see what my thrust is here, im about 100msl and temps are 70s 30% humidity on average.

RE: Kingtech K140E testing
Did you ever see the big fuel filters that they use on diesel trucks? There is a reason for that, Diesel is got a lot of junk in it....
|
RE: Kingtech K140E testing
Yes I had oil in the fuel. Berry says that diesel is fine in the Kingtech. I am going to give it a go in this turbine.
It will be interesting to see what kind of thrust the 140 has at sea level. I saw one on you tube that was putting out over 32 lbs of thrust. I am very happy with 25lbs 10oz to 14oz thrust at my 7400 ft alt. George |

I have been running diesel for the last few hundred gallons and I can not find a spec of junk you are talking about in any of the filters, not even the one that's on the filling can and never had to clean it since day one.

RE: Kingtech K140E testing
I also have one of those magical funnel filters but ceased to use it, because I could never get it to filter out anything, so I just pump and go!
Guys, if you haven't tried Diesel your own self, I encourage you to have a more open mind about it, but then if you are happy with kero, stay with kero. Perhaps it really is a cleaner regular pump Diesel here in California and Taiwan, as well as Arizona, because we just burned through 25 gallons at the DJS with no issues and there are recently more Diesel burnin KingTechs across the states and haven't heard anything adverse with their operations. Cheers, Barry |
RE: Kingtech K140E testing
I can tell you for a fact aviation fuels are extremely dirty, I take fuel samples everyday when I fly plus I use jet a and its just as dirty.

RE: Kingtech K140E testing
When using diesel is the turbine added at the same rate. What % <div>

RE: Kingtech K140E testing
If anyone crashes a jet with diesel on board, do you think there would be alot less chance of a fire using diesel vs Kero ?

RE: Kingtech K140E testing
Roger, a guy here at club has diesel it starts just fine. Im going to give diesel a try see if I notice anything.

RE: Kingtech K140E testing
Diesel is probably fine but I just feel that Kero is cleaner and doesn't smell so bad if you spill some, in the car or on yourself.
The price here in the northeast is pretty close. I get it at the local gas station and run it through my Mister Funnel before it gets into my 5 Gal. containers. It is then filtered by my fueling station before it makes it into the plane. Never had a problem with dirt or water. If for some reason the Kero was unvailable I would definitely go to diesel. It doesn't smell as bad as JetA. Bob |
RE: Kingtech K140E testing
the one reason i don't like the diesel is the smell out the exhaust, it's a very sickening smell to me, much worse then diesel truck exhaust.
the one local that Fender speaks of i did the initial flights on and it preformed great. the diesel here in Alabama isn't as refined as it is in the higher emissions regulated states (California...) and you get a slight smoke trail behind the turbine in flight, for those of us used to Jet A you'll think you've flamed out when you pull hard Gs and the smoke is more noticeable. around here the cost difference is about $1.30/gallon |

BTW, have you had a chance to run your K140 in your Futura yet? But it definitely seems logical that diesel would be a less flammable fuel during a crash. A couple of months ago I had a fire in my van (LiPo related). The fire burned itself out due to lack of oxygen (windows were shut tight) But the fire did catch onto my Jersey filler can and burned a big hole but no Diesel leak. In this case, the smoldering fire on the can was extinguished by the Diesel, since that smoldering stopped at the exact line of remaining diesel. Diesel also a safer fuel? I would say yes : ) |
