Wings and ground affects on F-1 Cars (no straight lines here )lots of DRAG and turbulence but you try one without wings and see how far you get in a race. The Penguin is a complex shape with 7 sub products each with multiple jobs, you guys are still relating to the board as if it were still a plaining flow form, dont forget the penguin is a fluid GLIDER. I dont want to start a semantics debate using high level philosophy of mathmatics AS will wil bore you all to hell, lets keep it ironing lady language nice and simple (how to bake a chocky cake). The ingredients of the FP have been around for hundereds af years, sailing boats, aeroplanes, ground effects race cars. If you want to look youlle find heaps. Our FP chocky cake is made up of ingredients from specific points from nine established specialists eg,(just a few NEWTON - ARCHIMEDIES - FREUDE - DUIBUR - REYNOLDS etc… Specific points were then assembled to create a FP choky cake Fluid glider. The thruster gaining its lift from surface area and the size of the wave(planing form) Whereas the FP is a fluid glider gaining it efficiency by wrapping the fluid flow over a lifting bodyform eg,Mig FOX BAT sure theres more drag but at very high speed you dont notice it. The moment you get a wave FP will perform basic manauvers with ease, the bigger and more radical the surf the better they go. (no use testing a Lambo on a dirt road) Happy surfing be in touch. Enjoy the cake. P.C.
How many hours does it take for you to shape one of your FPs? What about glassing and sanding?
Paul what trigonometric function is equal to cos(x)/sin(x) since you dont want to bore us with math, you should at least understand that.
cos x over sin x = cot x i am a fresman in college, sorry i had to jump in and steal the answer (school girl with her legs crossed and her arm waving in the air for the teacher to call on her) -TheLove
wrong!
sinx / cos x = tan x >>>>>> the inverse function of tanx is cotx, that being said, if you flip the sinx / cos x to cosx /sinx, the relationship will be the inverse of tanx which is COT X baby.
wrong of you to answer the question kid! Like I really needed you to solve that. it was a bullshit detector for someone else.
Take a teaspoon, knife and go to the sink…turn on the tap halfway and play and actually watch whats going on. You might think this is funny but youll be amazed at the different flow characteristics… A knife edge will release the water (sharp rails on the tail - more speed) A teaspoon curve down into the flow will wrap the fluid around itself (rails) A teaspoon facing curve up into the fluid flow will trap energy(turing into lift for FP at speed) and redirect the fluid flow… basicly you get wet. Concaves trap energy and if shaped all the way to the tail, you will end up with too much lift under the tail your board and will lose direction at high speed (concaves) If you hang a teaspoon gently from the end of the handle between you finger tips with the curve facing the flow move the spoon just touch the fluid flow and youll notice it will be drawn into the flow. (rocker) A wave isnt made of flat straight lines so if you have the right rocker to match the wave similar to(syncromesh gears) your rocker is made up of nose lift, mid section, tail lift is what gets you through the bottom of the wave without it youll nose dive for sure too much means you have to stay in the power. The FP concave it may look extreme at one centimetre deep compared with 3mm concaves at present that run rail to rail, rail to rail concaves can at times catch an outside edge, the FP concave stops 6cm from the rail to leave a flat neutral section which eliminates this problem. Also the FP concave is flat not dished, a dished concave turns fast edge to edge but a flat bottom concave is more stable all round(especialy at high speed) The planshape of FP concave is much the same as the tail on a big wave speed board. You cant compress a fluid. Because of this the flow is constantly accelerating to match the reducing area finnaly bursting from the concave tip releasing a water jet that is then tricked into returning beneath the tail of the board providing lift (stern pressure wave) Returning more energy to the board eg “Penguins” and “12 meter” yachts use these principles that showed up though our research. Gentlemen grab your cutlery!
good grief wheres lucy’s stand when ya need it…ambrose … our freud who art in heaven
sorry for ruining the fight, ill hold back next time a debate is in play, damm that fat penguin is weird lookin…
“Beats me why it came up, but TheLoveBelow is correct. cotangent(x) = cosine(x)/sine(x) cotangent is abbreviated as cot, sine as sin, cosine as cos (from the geeky kid in the back of the class with cokebottlebottom glasses waving his hand, knowing he won’t be called on until there’s a question he doesn’t know the answer to. Irritating but predictable teachers.)” I got this from my brother. He’s a fluid physicist among many other talents. I’ll admit the idea for his dissertaion came from one of our midnight conversations. But he’s the one that put the 10 years of dedication into the research. He’s paid me back with his research into MVGs which sent me on my quest that’s now in it’s 7th year. Just keeping it real. btw MVGs in the video linked below. First 8 seconds follow guy up beach with broken board. Look at board laying on beach in foreground. Hard not to miss. http://inletsurf.com/inletclips.html
That was a shameless plug. Actually I had nothing to do with the video and was no where near FL when it was shot. And I didnt even see the MVGs when I saw the video earlier in the week. Someone else, one of my NJ team riders, saw it and emailed me. So it wasnt staged. Just wanted to head off that attack. There is some good surfing (link) to be seen on those ugly white utilitarian FL boards. The FL industry knows it’s priority and it’s market and has led the industry with innovation and technology to match the skill and talent. Here’s a statistic: FL 15, CA 5. I know, I’ll catch hell. Oh, well. Shameless as it is, here it is again. http://inletsurf.com/inletclips.html
what the hell are mvg’s
to Christian from NJ “what the hell are mvg’s” Good question. Multi Vortex Generator. A small 2 finlet array placed in front of fins. Theoretically, they contribute flow to your fins, thereby reducing drag and increasing speed and overall fin performance. See MVGs on some random board at Sebastian Inlet, second video ( 2/2/04), Super Monday video link below. They are small (3/4"h x 2"l) so you have to look close and fast right in the beginning. or check out http://rdistributing.com/Catalog03/Page%2018.JPG Thanks for asking. http://inletsurf.com/inletclips.html
AHHHH ok, now I know. Sorry if the question sounded harsh, I was just liker hurghhh? But, yeah now I get it thanks for the info. Side note, what team riders do you have in NJ?
No worries Christian. I dont know if it’s a good idea to post all their names here right now, but if you contact me at mvg97@optonline I’d be glad to answer your NJ team rider question. thanks http://inletsurf.com/inletclips.html
cool stuff issat herb spitzer super xargers? truly adaptative surfing…and cool stop motion featre never done that befo…ambrose…thanks …bookmarqued to look at the others later
Ambrose, those are MVG2.2s on that board. I dont know who the owner is. Unfortunately, I had already gone back north by then. http://inletsurf.com/inletclips.html
