Active canard

[TotalPackage]

I come from the model submarine world, where we have been fighting a very similar problem called porpoising while submerged. the submarine community has spent years tweaking the "pitch controller":

currently several of the engineering types are trying to get the heading hold gyros from helicopters to do the same thing.

very interesting

I'm one of those engineers. I did the APC's for Skip (actually, all his stuff except the BE-VR) when he still owned SubTech and haven't been able to separate myself since then.

All the existing sub ones on the market (as far as I can tell from my research) are based on G sensors, not gyros. They measure tilt, which is adequate at the low speeds and low rates of change on subs. The UPC-1 is the best out there, but I'm a little biased :)

At the recent meet at Carmel, I was able to see a variety of boats of all different sizes running the devices I made over the last 15 years. I was amazed at just how well Skip specified operation of his products. Literally, the same unit worked in subs from about 14" long up to his huge 6' Type 23, and the only change was to select a different gain (3-positions covered that huge range).

They won't work in a high-speed surface vessel, as I pointed out earlier. Don't even bother wasting your time looking at them for running canards on a hydro.

Its alot of options here:Which one to use guess ill have to figure it out . I was considering 3 axis and a vtail mixer. Im imagining an algorithm that will try to keep the attitude level no more no less. The more is out of bounds the more flap the less of bounds the less flap. When its at what I designate as level it holds that setting until it needs to alter it to get it back in the right attitude.And endless loop.You can do alot with a microcontroller and one of these devices. I want everything properly intergrated so Im going this route no rc gyros per se though I know one of these devices is at the heart of some of the hobby gyros. These press right into the board.


When this is done right in my mind You should be able to hold the boat and as you rock if from a terminal angle to level the flaps should move to compsensate

Your knowledge is not the best. First, nobody said anything about turbine-powered hydros. Second, it was Jim Lucero, not "Bob". (Jim was alive in April 2009, when did he become "late"?) Joe Taggart used an adjustable front canard surface on his limitied hydros in the 1970s IIRC. The 1980 turbine Pay-n-Pak did not use an adjustable canard surface.





Mr Taggart was also the first to put a vertical tail on a hydro in the 1940s (the Tomyann I believe). He did it not to provide stability, but so that other racers could see his boat through his roostertail (which was a lot smaller back in the 50s than they are today).


.

wow thats a killer looking boat.

One pic of this boat is enough on this thread. The comments in it are truly irrelevant to me.Some of these cats on heres main focus is to be enigmas. Anyone got any helpful feed back or familiarity with any of these sensors?Lastly I dont care who started canards or whos living or dead . Im starting these on my circus case closed. Im as of now Im alive and well so thats whats relevant here. Lastly I never said the pak had "ACTIVE CANARDS" so for all those interested lets move on. weve been here before and the whole debate thing is useless.

[hazegry]

I was just saying I thought it was a cool looking boat is all, and I had never seen it. I didnt have any input on your canard idea but thought it was a interesting idea, its apparently allot more interesting than its author.

Anyway Ive been gathering parts:

[Simon.O.]

You do it youve built like one boat since ive been on here

It says "he" not me so it could be speaking of you. Dang doc you cant read lol

At the risk of getting an infraction notice from the Mods I will say this.

TotalPackage Stop being so confrontational and aggresivly defensive. Please try to keep with the spirit of a hobby forum and have some fun.

This is not life and death shiate we are doing here. Let's all chill and run boats and enjoy that

[Steven Vaccaro]

Lets get back on track. I would like to see more of the active flaps when your ready.

Interesting stuff.

Well, Jay is correct in what he stated about my Dad (Joe Taggart) in his first use of a canard. However the time frame was a bit off. Actually, it was late 40's early 5o's that he put a canard of his 7 liter TOMYANN. He used a brake handle to wing the canard down to keep the boat from lifting. He was not permitted to raise the wing because of the rules of the time. (I thiink that is true)
