I wanted to put TWO RB199’s in a boat. Warby believed FTS is possible on water, and I've been involved with powerboats since I was a kid.
What a sight seeing run on full reheat, amazing. Must be something to behold in person.
You feel it more than see it, every fibre of your body oscillates with the vibration. It's awesome.
Wonderful to see this project coming to life. “For Britain and for the hell of it!”
It'll probably go the same way as the Bloodhound project - run out of money, then get sold off.
@@daveworthing2294better than going all the way and killing the pilot. This shit is dumb if there is a human Inside it.
Great job, guys! Looking forward to the next steps 👍
Looks like David Warby has competition. Spirit 2 just broke 400kmph during testing recently in Australia. David is the son of Ken Warby, the current world record holder.
Awesome stuff! Can’t wait to see this progress.
RICCHHHHAAAAAAARD soooo good to see you again , my mind casts back to thrust , thank you
Good Luck..I love all speed record attempts ...water is the hardest..gods speed.
bloody hell, that looks amazing . I would have loved to see it in person
I truly wish the Team every Luck and Success ~ But the water speed record is another level, compared to Land Speed. While Dickie Noble is never the most charismatic leader, if anyone can do it He can ~ a good man who still believes in the Great in Britain
Scuse my French, but that is F**king awesome. Love the shape of an afterburner (reheat) cone!
Been waiting a long time for the British to have a go good luck
How about that mighty Spey … and what a sight running full reheat at dusk … we’ll done! The last time I saw a Phantom Spey running was on a development bed in Derby as a graduate apprentice in 1979 … that was memorable.
You Brits designed a great engine with the Spey and I was fortunate to work 15 yrs on our American contracted version from Allison, the TF41-A-1A powering the A7D Corsair. Thanks Rolls. 💪
So we have 2 British projects ThrustWSH and QUICKSILVER
I don’t want to be a wet blanket here but there’s a lot more to this than just engine power. Ken Warby never had more than about 6,000lbs of thrust available to him, yet his boat just kept getting faster with each run. For his first world record, he used reheat but it was never really more that a stop gap measure. His current world record was achieved without one.
The Spey, in full reheat, has about three times as much power as Warby’s old Westinghouse engine. So what’s the big deal, you ask. Shouldn’t be a problem, you’d think.
Stability is the problem. Nothing more or less.
Ken Warby had one of the sharpest minds in the country in his team, along with his own mechanical engineering background and expertise with a jet boat.
The problem with the world water speed record is similar to the problem with racing cars. When pushed beyond their limits, they can flip. Just look at the accidents that claimed the lives of Donald Campbell and Craig Arfons. Cool, you think, just put wings on it and create downforce. But this doesn’t work the way it does with cars.
To understand this, you need to understand aerodynamics, particularly stability. You want the boat to be as neutrally stable as possible. To do that means having the centre of pressure very slightly behind the centre of gravity. Unfortunately, the design of hydroplanes makes this almost impossible. The largest area is usually forward and the engine - the heaviest component - is at the back. That means that if the bow hits a small wave - or anything that provides an upward impulse - the bow will rise, generating lift while the weight of the stern pulls it down, creating a positive feedback loop from which it is impossible to recover. Donald Campbell’s crash was a perfect example of this. The bow started to lift and once it started it wasn’t going back.
Most people would look at Ken Warby’s boat and say the wing was to keep the back down, like it would in a racing car because in a car, you need the tyres to keep traction. But this is exactly what you _don’t_ want in a hydroplane.
It’s my belief that Warby had the rigger’s angle of that wing trimmed to make Spirit of Australia ever so slightly light in the stern. Not so light that it lifted clear of the water but light enough to reduce the effect of the engine weight, while keeping the rudder in the water. This would have had the effect of moving the mean aerodynamic centre further aft. The mass of the wing would also have created just enough inertia to stop the sponson walking that always affected Spirit from becoming a major problem.
I think Richard Noble understands this. His Thrust land speed record project from the 1980s took him within about 10 km/h of doing the same thing. He called in Ron Ayres to do the aero for Thrust SSC and used him again for Bloodhound. Hydroplanes are worse. Much worse.
Racing cars have a few degrees of pitch stability before they flip. Their margins are small but manageable. Hydroplanes are a whole different story. Unlike racing cars, the surface they run across can be unpredictable. The slightest ripples can cause a disaster because their stability margins are much smaller. It’s my belief that by fitting a wing to Spirit of Australia, Ken Warby increased that stability margin slightly and opened up the possibility for higher speeds.
If Richard Noble is the kind of character I think he is, he will be looking very carefully at this. I think if anyone other than the Warbys understands this, he does. Ken is the only world water speed record holder I can remember who died in his bed and the only one who did so while still holding that record. And that says it all.
Wahoo what a beastie 😮
I ran a ran a GP hydroplane back in the 80's (crashed it at 170) & I'm just putting the finishing touches on a 4WD AA/BFS streamliner. I'm trying to imagine sitting in front of that big-ass engine trying to go 3-plus in light chop, that's gunna get your attention! 😳I knew Ken Warby in the 80's & he told me how spooky the sponson walk was beyond 200. Kevin Hickling built a boat as well but his survival instinct kicked in. This record has spit out a lot of people.
Are there any pictures of Kevin Hickling's boat? I've not heard that name in association with all out record boats
@@weatheranddarkness I've never been a picture taker & I left Aus for the US in 88. Kevin would be in his 80's now & lived about the Drummoyne area of Sydney back then.
@@nzsaltflatsracer8054 I guess I'm just curious about various solutions to the challenge.
@@weatheranddarkness When it comes to all the big records you have to innovate to go faster than everybody else. The same hammer drives in the same nail at the same speed.
I can't fathom how someone thinks this is a good idea and worth the challenge while knowing that it's probably a 80+% probability of death. Some rich old British dipshit will find a cocky younger man with a point to prove and I'll go on record saying if this makes it to full record attempt stage will absolutely kill the pilot. So dumb. Make it a drone. No need to kill somebody because a bird just dove for a fish and made a ripple or a dolphin farts or a turtle surfaces. So dumb.
well that's something u don't see every day...amazing footage when it lit up
Shock diamonds, baby! Not much can compare to full reheat, particularly on a lovely old engine like a Spey.
Am I right in thinking the exhaust ideally should be bluer?
Probably the camera automatically adjusting colour/exposure to give mid grey average.
10:27 the look on Richard's wife's face really says it all.
Only seeing this today , not recieving sub. Notification
Engine says, where is my plane?
There is a very good reason why Ken and Dave Warby don't run their engines with reheat. Learn from the world water speed record holders since 1978.
Go on then? 😊
Yeah, what's the reason? In one interview, Ken Warby said they had a secret recipe for success, I always suspected it was the T tail, which no other boat has ever had. His son Dave's boat has it too.
The problem with water speed record hydroplanes is that they want to flip. I have a turbine powered 1:4 scale model of Spirit of of Australia, and the T tail is trimmed so if the angle of attack increases it brings the back of the boat light. I don't know if works at speed, I haven't yet had the stones to give it full send.
HI.. IM CATCHING UP. KEEP IT GOING. AND ALL THE BEST
Who brave enough to pilot it??
I really hope this doesn't go the way SSC went , get it built then bang no money left 🤔, I put money into SSC
I can’t believe they are running the engine standing so close to an open engine inlet.
I reckon they know what they're doing. They don't just turn up, bolt it to the ground and send it, there's a huge amount of planning and risk assessment that goes into it.
Who, by jove and the holy St. Christopher, burnt that neatly cultivated english lawn at the airfield? Bollocks!
Sounds very negative I know but O lost all faith in this type of thing when Bloodhound went belly up.
How people are giving money this time is beyond me.
Seems to me these projects are just a way to keep Richard Noble purposefully occupied in some way.
Great -good luck stay in touch lads. lol TOMMY27
I do worry. Take care. "The record is one of the sporting world's most hazardous competitions. Of the thirteen people who have attempted the record since June 1930, seven have died. There have been two official attempts to beat Ken Warby's 1978 record, and both resulted in the death of the pilot; Lee Taylor (1980) and Craig Arfons (1989)." en.wikipedia.org/wiki/Water_speed_record
You bloody British blokes are funny! It's known as an After burner. Reheat is what you do to cold pizza not a turbojet engine! Cheer's.
If you bothered to watch the documentary, you would have heard them say "re-heat, or afterburner"
I take it you're a Yank. Who has the Land Soeed Record anyway? We can call it what the f**k we like and anyway, if uou listen, he does say both meanings!!!!
Thanks to Sir Frank Whittle the jet Engine was invented here, so please let us called it our way.
