Mikko, nice work. on my previous post I was wondering I should quit this discussion and go to an all new keel as the preformance from a keel...
Yes, I have used the Mikko´s data to make a rough calculation. I just wanted to know how better the new keel would be. I am very impressed ...
After reading the ORC document some concepts became clear to me as how to define the correct keel. I have made the following execise: - used a...
Thanks! I'll read carefully. Look forward to seeing the L Keel results.
Mikko and Joakim, I am really impressed tge degree of technical discussion my keel proposal has triggered. This is the first time I use a forum to...
L keel concept is also alive! I made some simulations and tghe geometry resulted in something like this picture ... how do you like it?
I am back with the wing keel model rebuilt. The file has been reduced to 13Mb so I guess Mikko can now you use into the CFD simulation (if you...
Soren, I appreciate your concern! Eventually I will share the fasten strategy and you will have the opportunity to give me some hints! Thanks...
The bolts will be fastened along the 1500 x 125 mm fin section. It's wide enougth to drill 3/4 to 1" threads. I didn't calculate it yet but i...
I have notice that on the keels like J111. Instead a linear thickh increase a kind of "bell" shape. I will simulate the linear profile and later...
Checking the current keel dimensions I concluded that the fin profile is basically 63xx family with thick % chord from 6,5% to 8%. I will be...
I will reduce the cord to about 1900 to give it some simetry to the top. The maximun thick of 250 will give me about 1000 kg which is the desired...
OK, how do you like my new L-Keel? It´s 40% deeper than the wing one and I guess some 200Kg lighter. Suggestions before I dive into my...
Ok but how do I design it? Is it a half bulb attached to the bottom of the fin?
Ok Paul, I am open for suggestions. You don´t like the bulb I designed or you don´t like to usea bulb? What you suggest to add to the fin?
Yes, I have been thinking of it! Instead of only a bulb I am considering to build a bulb with a bit of fin which is the additional draft. Doing...
Lot´s to learn yet ... what about adding some few inches to the bulb ahead the fin, make it flatter and add the beaver tail shape? do you think...
Splendid! I´ll try to speed up the wing model to monday so that you can compare the results. In the meantime some additional questions: - where...
just as additional detail I am attaching the file obtained during the keel scanning. the winged keel dwg sent before is result of this model...
Mikko, thanks for reworking the bulbkeel file. We´ll rework the wingedkeel file and send asap.
