CNN says you can flame out a jet engine flying through hurricane

ROTFLMAOPIMP. “it doesn’t happen with a propeller plane...as much.”

Wow. Doesn’t anyone do any research anymore? I wonder if he has a clue as to what drives the propeller on a “propeller” plane.

Oh yeah. He doesn’t.

you don't have to do research when people will believe anything and everything they hear on the tele.

It's a good thing the people who design this stuff don't get their learning from the news.
 
"...57 miles per hour - if you want to go old school and fly through it in a propeller airplane, because they dont fly jets through these things they fly props, if you get a jet with the wind going the wrong way, you can get a flameout - that doesn't happen with the propeller planes... as much"
 
You missed the best part.

"Hurricane will be a like a Mike Tyson punch"

Really? WTF does that mean!
 
You would think after spending a full year covering the mh370 missing plane they would know how one works!

It’s completely understandable, planes aren’t used to high winds
 
I am no expert in this area. Is there any truth to the idea that flying in a hurricane can cause a jet engine to flame out? I could certainly see ingestion of a large amount of rain at low idle (as you might set it for severe turbulence) might cause the flame to extinguish. Given that not all prop planes = piston engines, can the above happen to turboprops, even if not as often as it might in a jet? Thanks to those that know more for educating me on this topic.
 
Yes, if you dump enough water into the engine, it can flame out.

And...if the wind is going the wrong way...well, yes, it can compressor stall in flight or hot start on the ground.

All of this is true. But that wasn’t really the context of the news story.

The point being that a turbine engine is turning a prop instead of a fan and is susceptible to the same issues.

I am sure the hurricane hunters have been fortified to an extent for their mission but it is still a turbine engine running the show, so to speak.

All true. Procedures call for continuous ignition ON so that helps.

I was really more answering the question in post 21: "Is there any truth to the idea that flying in a hurricane can cause a jet engine to flame out?"

Plus, the title of the thread is:

Which just happens to be true.

I know of a C-17 that had a 4-engine flameout due to water ingestion while flying through a typhoon doing humanitarian evacuation.

Alright, turbine engine engineer here with a few clarifications.

On a turbofan/turbojet engine, crosswinds tend to have a bigger impact on inlet pressures at the nacelle inlet. This can be how some of the crosswind limitations may be applied, and it's something that we have to test for during certification, basically making sure that the inlet pressure doesn't get low enough for a compressor stall which is a bad thing. Turbofans tend to be more susceptible to compressor stalls and there are a lot more systems involved in most of them to try to prevent them... various pressure relief valves, bypass valves, and variable geometry vanes on the stators for the compressor.

Turboprops tend to be different in terms of design, enough such that compressor stalls can happen, but they pretty much don't. I think some of this has to do with not needing optimization for higher speeds like you do with a turbofan, and probably also something to do with not having a turbofan in front of the compressor. The propeller behaves differently than a fan (even though its function is essentially the same) and probably makes for more uniform air pressures in front of the compressor.

With that said, the issues are during lower speeds and crosswind landings especially. The winds of a hurricane may be shifting a lot, but you're still moving forward at a significant speed. That report is just a load of crap by someone who doesn't have a clue what they're talking about.

The hurricane hunter aircraft are fortified, but to my knowledge they aren't doing anything to change the overall behavior of the engine, it really has to do with making the plane itself tougher against hail etc.

Oh, hail. That's the biggest reason I could see for using turboprops vs. turbofans. The props tend to be tougher, and easier to make tough against hail. Turbofans need to be tested against hail ingestion, but it's not the same.

This is why I don't watch or listen to the news.
 
The thing to takeaway from this is how bad the news media gets things. We realize it in this case because we are knowledgeable in this area. So just remember that when watching any other news story.

I really don't hold the media any more accountable than Hollywood. We all know how bad Hollywood gets things wrong in the name of entertainment, the media isn't much better.

The problem is, the current news media has turned into entertainment, rather than actual news. It's all about ratings, it's not about doing the job.

I used to know guys that flew the Air Force Reserve C-130 Hurricane Hunters out of Keesler AFB. According to them, their aircraft are standard C-130s. The only provisions made are for the sensors and dropping buoys. Other than that, standard off the line C-130 from Lockheed.

They also told stories of the damage they had taken on missions, including losing multiple engines due to hail damage to the oil coolers.

Interesting. I had heard different about the P-3s that NOAA uses. I'm not surprised a stock C-130 can take the abuse, those things are flying tanks.
 
Just apply the incredible lack of knowledge regarding everything related to aviation and apply that same startling lack of knowledge to most everything they report on.

I've seen the NOAA WP-3s. I know they have received unique modifications for the sensor platforms they are carrying, such as the UFO under the nose. I can't say definitively whether there are or are not any other airframe/engine mods, but I suspect very little was changed. Don't forget though, the P-3 shares a basic wing and engine design with the C-130.

I know they try to plan their routes through the easier parts of the storm to avoid the heavy stuff, but we are talking about a hurricane. Even the not so bad areas can still be very nasty. Not a job I'm terribly envious of.

I'd sign up tomorrow.

I just recall one story the crews told me about. Not sure if it was a "fishing" type story (fish gets bigger with each telling). On this particular mission they found their C-130 with two failed engines from hail damage, struggling to make it the 200 miles back to Miami on the remaining two, one of which had increasing oil temps due to a damaged oil cooler as well, and just making it into Homestead AFB.

I can't vouch for the legitimacy of the "story", just that was one that was told to me. If true, sounds hairy to say the least. :p:eek:

But can their C-130 hold altitude when the fuel tanks are empty..??? :rofl::rofl:
