Ice Bridging

Ground school instructor said something about oil wells back at Skyway, but I have no idea if he was full of it or not.

It was used to drive a generators and actually drive the pumps that pumped crude out of the ground in the Middle East. Pretty good engine considering it ran on the crude oil it pumped from the ground with no refinement.

Consider the PT-6 like a kid blowing a geared pinwheel.

Can anyone name the original intended purpose of the PT-6A? Class? Class? Beuhler?

I heard that in ground school too. They also said that is how the "A" found its way to the back side of it. Airplane.

My boots have ridges and I was cursing up a storm yesterday trying to climb through moderate mixed as I watched the boots just bridge instead of blow the ice.

Are you sure it was bridging? or was it just not shedding all the ice?
Did you wait for it to build up before you blew the boots? or did you start blowing it right away?
 
You could actually watch the ice expand. Probably blew it first with a 1/2 inch. In cruise I probably would have let it build a bit more but I was trying to climb through it to get on top.

People say the NW has bad weather to fly in. Aside from Socal, it's been the best weather I've ever seen. There's fog a lot and it rains... occasionally there's some ice, but nothing to really care about. There's no convection whatsoever, so.. .really there's no significant weather.
As easy as it is to fly here(can't even tell you the last time I encountered so much as a bump of turbulence), I'm starting to miss dodging thunderstorms.

I knew it was designed to pump oil, but I didn't realize they were feeding the thing from the stuff that was coming straight out of the ground.

No wonder the thing will burn nearly anything.

I think you meant people say the NE is bad

yeah man, that was why they use them. Could you imagine having to go out and refuel tanks for the damn things... There are way to many of them.

I'll second this. I knew it had power generation and pump history, but I had no idea they were actually burning the same stuff they were pumping!

Not only that but some ran continuously for years at a time, even maintenance was performed with them running. I've heard of one being removed for overhaul with something like 60,000 hours on it.

I've heard the same. I have no doubt that the PT6's in aviation use could run FAR longer TBO's, but in all fairness, there's a huge difference between shutting down a pump because the engine failed vs dealing with an engine failure in flight in an aircraft. Also, consider that in said 60,000 hours, it probably had 5 cycles.

what that the stuff i reported as moderate rime last night on my descent into GFK?
 
Ridges are good for many applications. Be it ice boots, mountain ranges, or ruffles chips. The chips just work so damn well for dipping!

Jhugz, can I get a play by play of that flight through the ice? I usually enjoy your profanity laced tirades. Raw comdey at its best!
 
PT-6 was a pump turbine, hence the acronym "PT." They would put them on the side of oil / gas pipelines to pressurize the pipeline every so many miles.

Heated Wings.
Heated Cowls.

Continue reading newspaper. :)

Don't envy you guys.

Exactly. I was glad I had heated wings and Cowls the other night. Moderate Rime Rime on approach and while getting vectored.
