Blue Thunder II Emergency Landing
HTML-код
- Опубликовано: 17 окт 2024
- During the Tuesday afternoon qualifying session for the 2017 Reno National Championship Air Races, the pilot of Blue Thunder II, John Parker, experienced a catastrophic engine failure that took us out of the races for this year. The Blue II telemetry crew, 51 Aero, is currently examining all the data to try and determine the cause of the failure. Regardless of the cause, the ground crew was extremely happy to see John safely on the ground and is looking forward to racing another day.
//UPDATE//
From John Parker, the pilot of Blue Thunder II
"After an excellent year of racing by all competitors at Reno, the Blue Thunder Crew has had a chance to look through the data for Tuesday’s event-we wanted to share a bit about what we learned so far.
Although the root cause is still unclear, the engine experienced an overspeed event shortly after takeoff. This resulted in valve float, causing a number of valves to come into contact with their respective pistons. The affected pistons failed, causing a rapid degradation of engine rotating components. The camshaft was broken, the crankshaft was damaged, and two connecting rods departed through the case-one of which impacted the primary electrical system’s battery, causing a loss of electrical power as well.
We’ll continue to analyze the remaining clues, but rest assured the team has a plan to return to Reno next year with a vengeance!
We’d also like to thank all of our fans and sponsors for their continued support-we’re all looking forward to another great season of airshows and racing ahead."

There's a weird noise, sounds like the engine stalls just before the end of the run way, I think that's before the wheels lifted off. Was that the over speed event you mentioned?? Or could that be something failing just before your telemetry recorded the over speed??

Yikes! Well done John for getting her back on the ground in one piece.
Engine sounds sick from the very beginning...
R Diaz I was thinking the same thing. I didn’t know if it was a video hiccup or if it actually coughed at first. When he didn’t abort I figured he had to be beyond that point.
I didn’t like the sound of that engine when it first rev’d up for takeoff.
Superb flying again Elliott
This was John Parker flying, Elliot never flew Blue Thunder.
@@Stevo71 oh, ok. Superb pilotage in my book anyways
0:26 the decrease of RPM you hear, was that the first indicator that something was going wrong? If you had the chance to relive this moment, would you have kept the plane on the ground rather than taking off?
Mayb but im not sure
Incredible piloting.
I am very sad to say that both the plane and her pilot have passed away after a rollover accident in Stead Field, May 1st, 2018. Rest In Peace John, we'll always be watching for that missing flash of Blue Thunder in the sky over Reno.

I know it's Blue Thunder II, I was just shortening the name.
Zach Boyd RIP John. You will be missed!
John and Jan were good friends for many years. I miss them both. RIP to great Aviators.
Just a simple electrical issue, i.e. it threw a leg out of bed and broke the battery. Good to see it returned safely.
Does anyone know for sure if he went off the end of the runway? Looks/sounds liked packed gravel????
Yes. The aircraft did depart the end of the paved runway onto a compacted gravel overrun area.
Lol. It took a root cause analysis to come up with over-rev? Did you all watch the video? You can hear it. You can't rev a Falconer V12 that high and expect it to hold together. It's a Chevy straight 6! I wouldn't turn that thing over 4800 RPM. Anyway, good luck picking up the pieces, and good luck in 2018.
It's actually based on the small-block V8s.
The engine sounds rough as hell. There was definitely something off!
Made a great video, major traffic
In the back of his mind he's saying, "Damn. That just cost me $50,000 and a few months worth of work." Maybe I should buy a Canoe and a Paddle, less moving parts.
Did the plane loose complete power around the 1:58 mark?
Yes
Ya ... that's never good.
At least it happened within range of the runway.
Overspeed starting @ 0:43?
I think it started while he was still on the runway...
Just kept pushing it. engine wasn't meant to do that kind of thing
He did a good job of getting it back. He used every last bit of life from that engine to take him back to the runway.
Never should have taken off after having that sputter on initial roll. Might have been a simple fix instead of an overhaul not to mention the safety issue. Some lessons are learned the hard way.
Maybe, but when the motor first stumbled he might have been above Refusal/Abort speed?
I was going to see if anyone else noticed that..
No abort speed in a single if it goes bang that's it deal with it
I didn’t like the sound of that engine when it first rev’d up for takeoff.
I would have liked to hear the audio traffic on that one.
What's really sad nobody know he died in this plane. He crashed it a year after this. May 1st 2018....apparently he was having problems and called a mayday at attempted landing. While landing the plane flipped over. He died on scene.
First, overall, nice job. However, I would have thought he would pitch up far more aggressively (trade airspeed for altitude) than he did when it became obvious he was losing the motor. Also would have thought he'd pull the nose around a little harder/little more G to get pointed back at the runway quicker. A slip on short final to bleed off energy might have kept him on the runway. Anyone can QB it afterwards. Nice job.
@Mark wow what a nice person you are.
Excellent airmanship. IMO, this is why it's so difficult to adapt automotive type powerplants for aircraft. That engine was SCREAMING on takeoff, and most racing applications such as NASCAR or F1 have a hard enough time as it is keeping V8,10, or 12's together for one race much less dealing with the vibration of a gearbox/propeller combination. On top of that, cooling issues are singularly unique for aircraft. That's a lot to deal with.
Tell that to Rotax, maker of thousands of liquid cooled automotive derived engines with gearboxes that have been flying safely for years.
True enough, but at most 115 HP, we're not exactly talking a redlined Reno participant, are we?
fastglasspilot well the mustang does alright when operated at normal power levels, and while it's not exactly a converted auto engine it is liquid cooled. There are other examples I'm sure. Not to mention diesels.
We have to get out of the "if it ain't broke don't fix it" mentality that is keeping GA aviation chained to 60's tech.
... and that was my point, automotive conversions. Even the Rotax 900 series were aviation from the getgo. Wasn't the Falconer V-12 in the Thunder Mustang an offshore racing engine?
fastglasspilot no idea about that V-12. I just think it's a shame that people have to pay over $40,000 for a normally aspirated 200hp engine when they could easily if they wanted to make a certified auto derivative that costs 1/4 of that.
Man this thing has a weird sound, is it a pair of V6 engines?
NZ Salt Flats Racer basically two Chevy straight six’s 60* apart on the same crank.
It's based on the Chevy small-block V8 (sort of, it also has some big block parts), but it has 4 additional cylinders, so it's a 90 degree V12, which is why it sounds weird. If it were two inline 6s at 60 degrees, it would sound like a normal V12.
I didn’t like the sound of that engine when it first rev’d up for takeoff.
So it was a valvetrain issue. Man if I’m in that stuff I’d be extremely careful when I do an automotive engine conversion 4 my P-51 replica.
Bit more than a valve, it says it blew a conrod out the block. More like a timing chain issue.
@@christianbuczko1481 As result of the valves contacting the pistons. It was a catastrophic failure caused by a poorly designed valvetrain.
the cause of the failure? Tuning an engine and pushing it beyond safe limits
You don't know where the limits are until you go past them...
That's what racing is all about! - Edit: And, actually, it's very likely that the engine could have handled the over-rev without issue, if it had a properly designed valvetrain.
This is literally a stunt plane
