Agreed. If its a shit system, its shit for everyone. Everyone is in the same boat (excuse the pun), so either Ineos has modified the system and their mods aren't working, or their engineers just aren't coping as well as the other teams engineers.

Either way, it comes down to their own team - again.

Oddly enough in most of the world, if one car of a model goes wrong, it doesn't mean that all the others do. There is even the concept of a "Friday Car" which has lots of problems. Is it different in NZ so that if one breaks they all do?

No, but if there is a faulty part in one of the models, the rest are recalled.

Surely ETNZ should arrange for the 3rd party supplier to go to fix the Ineos boat, because we are told ETNZ didn't build it, but they did contract it. Which is essentially what Ben is asking for

 

And Miffy, if that is the case, why hasn't ETNZ done such a recall?

Shrug because it isn't a consumer product and I take Ben Ainsley's complaints with a grain of salt. The other teams demurred when given the opportunity to join his complaint.

But that's my point, other teams may not have had a problem. May be hardware, may be software, but without the software INEOS can't tell, and there is no evidence that the FCS engineers have visited, tested and confirmed there is no problem either.

[Miffy 2,144]

Who knows at this point - if the issue is the software side & it isn't the component associated with the OD elements and teams are supposed to write their own code for control systems and tinker with inputs based on data from the sensors - why would anyone else make the software for them. I just don't know if anyone in public domain has that information.

Another solution could be for all the teams to have and embedded engineer from the company that builds them to help with integration and fixes and maintenance schedule ect., just like F1 engine suppliers do with customer teams.

Look I am NOT going to espouse the merits of these boats cos I think they are shit.

However, comparing a "Friday Car" to the FCS is a completely false equivalency.

People who own Friday cars don't have the resources to inspect and potentially rectify any problems on a daily basis.

If INEOS receieved "Friday Foils", they could (and should) have done whatever is necessary to rectify the problem and bring the FCS into spec.

If INEO are being shot in the foot with a poor quality FCS when other teams are not, then it can only be INEOS are pointing the gun.

And that doesn't solve underlying integration/systems work at the team. 

For example, you could have a Mercedes engine and end up like Williams or have a Renault or Honda engine and perform like Red Bull. I just don't think anyone has enough information to determine where the breakdown is.

No, I agree. But as INEOS are saying its the one design bit then ETNZ should be moving heaven and hell to get that sorted OR prove that it is not. I don't see any evidence of that effort

[Miffy 2,144]

lol suppose there's hydraulic actuators and cylinders and pumps and the reliability is improved by minimizing pressure spikes and also pulsating fluids - and all the mechanical engineers and software guys on the other teams have figured that out and made the software run that way & there's one dumb team with poor systems integration work who can't figure it out - whose problem is that? I just don't get it - Inoes is funded by a Brexit billionaire, figure it out like everyone else because it seems like one party is whining. I just don't think there's enough information yet.

[nav 591]

It's pretty simple. Some have been after the software for a while, today gave Ben a worldwide audience to ask for it in front of - but he needs to make the case that there are no other domestic mechanical issues before the software can possibly be to blame or provide any relief.

Don't forget the other issues aboard Fraka2 today and get sucked into a one issue mind-set.

But given all that it sounds to me like it would make sense to put a small expert group together to consider options for FCS reliability improvements - before it ends in tears

No but what it does is enable the team to effectively debug their system and identify if the issue are on their side or the FCS supplied parts side. 

Yes you could preform like Williams with the Mercedes engine, but the role of the integrated Power unit engineer is not to help the team with aerodynamics and performance but is instead there to insure the power unit is installed and running correctly. That is what i am suggesting having a embedded engineer for all the teams to insure that their FCS systems are installed correctly to spec and functioning properly. 

and you are correct that we dont really have enough information!

They're actually there to ensure it is to spec - if the team wants to run the PU at high levels to compensate for aerodynamic problems, or ignore cooling issues at their own peril - it is the team's decision. It is too complicated to be able to diagnose remotely without more information.

For the AC35 FCS ETNZ used Beckhoff sensors and controllers onboard: EtherCAT-linked modules controlled by special version of embedded Windows developed by Beckhoff. They also had a CANBus system for valve actuation and human interface input. Now I have no inside knowledge of the AC36 system but it seems probable they're using the same kit again because their FCS band is back together: Ryan, Vito, Stefano, Carsten etc. 

My guess is ETNZ sends an FCS binary firmware update to the teams which they download to their Beckhoff IPC. Seems unlikely the original source code is distributed or even openly reviewed by the other teams. Across my four campaigns source code review, even for mission critical code, was not SOP or even asked for. 

But with these systems post-mortem fault diagnosis is problematic due to insufficient logging: hard to know the exact state of everything with millisecond precision because their logging system is not designed capturing the state of hundreds of channels at 1KHz and not all critical signals are even recorded. For example, if a FCS valve is stuck open or closed was it caused by a logic fault in the software, EMI in a sensor signal, a bit of unflushed metal caught in the valve, a valve controller MOSFET temporarily in thermal shutdown mode, human input device error, human mistake, etc? Often hard to tell which. Or none of the above.

No, there are tolerances with any one design part, the idea that everything is precisely identical is a farce.

POINTS TO NOTE ON THE FOIL CANT SYSTEM (FCS) USED BY ALL COMPETING TEAMS

SHARE

 

     

The foil cant system (FCS) is a one design supplied component designed and developed by ACE for all competitors. It has been used since the inception of this class.

- All teams are responsible for the installation, ongoing maintenance and operating procedures of their own systems.

- All teams are provided with full operating and maintenance instructions and programs to ensure effective and reliable performance.

- For the past few months there is a weekly coordinated call between all teams every Friday in an open and transparent environment to discuss the system and address any developments collectively.

- The maintenance and start up schedule that has been developed is a comprehensive schedule that is shared and in possession of all teams.

- In Emirates Team New Zealand’s experience if all maintenance and start up procedures are followed correctly; the system operates as designed.

- Emirates Team New Zealand has no access system to ensure these procedures are followed by any of the teams.

- In answer to INEOS TEAM UK’s suggestion that they only received a software update at 12pm yesterday.
o This is completely incorrect and inaccurate.
o The last software update was delivered to all teams last Friday following extensive consultation with all teams. Not midday yesterday.

- As far as The Defender is aware INEOS TEAM UK’s Foil Cant System is fully operational.

Why is the problem team specific? Did INEOS design and install their own system/software and now that it's not functioning Ben wants all the teams to help them sort it out?

But how the fuck do you spend three years to get to this point? 

After yesterdays gong show Ben has lost any psychological advantage he had with his petulant child, sculling 'it's not fair' attitude in the presser, pretty clear he's under pressure and fragile. They have about 3-weeks to get competitive, take out Xmas/New Year downtime and it's probably closer to 2-weeks. They're simply gone, now who will stand up and take the bullet(s).

The "TWICE" was more about the FCS issues dating back to B1, and the implication was that it's unlikely they received bad FCS both times.

I think their problem lies within their own-developed and -designed ECC system. They need to go back and decompile their code and logic ladders and start again before the Prada Cup, but it goes without saying that they need competent engineers to do that in the first place! And time...

That is preciously my point. I don't think it's the OD supplied components at all.

@JALhazmat Comparing 8 production FCS systems (and spares) to 4 teams is worlds away from the number of OD parts delivered to Olympic teams. Not to mention, I would imagine it's much easier to get consistent parts when they are CNC machined vs a couple of minimum wage employees higher than a kite from the epoxy laying up nacra hulls. I'm not saying the parts aren't built to tolerances, but I am saying I'd bet the tolerances are very narrow.

[Stingray~ 2,265]

Maybe the system has API’s advertised to work in certain ways, but they sometimes aren’t performing as advertised and they don’t return good-enough diagnostics in response. Without the source code, you can’t tell wth is actually happening. 
 

The FCS being so absolutely critical to these boats, let’s hope a resolution can be found. The ETNZ statement is disappointing, being ‘offensive’ instead of ‘accommodating,’ yikes.

I think something along these lines is likely. FCS has to accept input from the individual team's controls- whether that's as simple as "Up" or "Down", I don't know, but given the complexity of these boats that seems unlikely.

INEOS being one of two teams to launch a smaller scale trail boat- they must have had to develop their own version of the FCS for that. I wonder if they made some macro-level control design decisions based on how their internal small scale FCS worked, and they are having some issues apply lessons learned there to the OD FCS...

It could be something as simple as a timing mismatch (for example) in the ECC sending a signal to a ratchet-type lock holding the arm in place (rather than relying on a hydraulic lock, which leaks) to release the arm, causing the lock-up and  the motor keeps pumping 'til the batteries overheated and shut down.

No argument here. I thought you were referring to the two controllers they cooked yesterday. I think the FCS is a little dodgy, which makes sense for a first gen system. It seems like Ineos ignored the problem, thinking a fix was coming. The other 3 teams figured out how to deal with it.

Just a shame port foil has been drawn as fully down instead of the actual sailing configuration.

still trying to figure out the answer to the question: 

Had one boat carried code one in the last race and stayed foiling, could they have completed the whole course in less time than that race took?

Why is the problem team specific? Did INEOS design and install their own system/software and now that it's not functioning Ben wants all the teams to help them sort it out?

But how the fuck do you spend three years to get to this point? 

After yesterdays gong show Ben has lost any psychological advantage he had with his petulant child, sculling 'it's not fair' attitude in the presser, pretty clear he's under pressure and fragile. They have about 3-weeks to get competitive, take out Xmas/New Year downtime and it's probably closer to 2-weeks. They're simply gone, now who will stand up and take the bullet(s).

Calm down. It is only a race or game....

According to Jimmy, doubtful. Up on the foils quicker, but too much drag and likely slower around the track than with a J1.

CZ’s are a lot slower tacking/gibing (getting it around the forestay) as well, which means greater speed loss each time.

but thats not the point  (or the question I am posing)  "faster around the track" is great   BUT does it make up for the time spent not going around the track!

I really think Jimmy's answer was off the cuff NOT the result of any considered analysis.

Faster around the track would mean lower time to get from the start to the finish. It's great to never fall off the foils, or to be able to get back up on the foils, and then you might be able to make some gains at that part of the race, but if you are slower overall than the other boat, you are not going to win the whole race.

Regret having to reprimand you, but it’s François Chevalier (Maurice was a famous chansonnier). And it’s Luna Rossa, BTW - rosa’s pink

All these mainsail control components don't appear to be nearly as advanced on the challengers right?? Looked like a primary (center) and dual secondary hydraulic rams although I'm no expert.

Attached one pic of Ben's "outhaul" setup. Looks basic comparitively. 

 

 

Center pictures show a track hung on the internal foot with the mainsheet attached to it like a boomless 1990s beach cat (PIC 1) , so not super innovative in the end, but different, yes. Thanks for posting these, another part of the puzzle.

anyone still trying to argue that the boat with a code zero would not have won that last race?

That’s the visible part. I doubt we will ever find out what’s between the two membranes.

Terry Hutchison said the Code Zero is basically worthless and that it would not have helped.  He said you can get up in lighter wind better with the code zero, but it has so much drag that you will never win.  He said you have to learn to up with get up with the large jib.

With all due respect to Terry's superior sailing ability, IMO teams may now re-assess the use of bowsprit tacked jibs. Especially if both competitors are using them (at the bottom of the wind range) all I can see is advantage, despite the known drag.
