I'm not really sure what your goal is here. I would assume you are trying to find the deflection forces required to somehow optimise the control...
I'm not suggesting this as an actual avenue to persue, but... Assuming an uncored fiberglass hull, how much area would you need to build a heat...
We got third place out of about 30 entries. We did the 2 mile course in 8.5 minutes, first place was around 6 minutes. We built everything in only...
Not saying I don't believe you, but I don't understand. Wouldn't this cause seperation at practically any positive aoa?
I decided to go with a compromise, 16x33.3 cm turning at a 50% overspeed. Here are the plots for torque and thrust. The J values 1.5 and 2.05...
What about hydroforming? could you hydroform a sphere of the right size and then cut it in half? I have no idea what the typical tolerances are...
Ok, I think I did the math properly. I finally tracked down a paper (Thank you Heimfried) by Newton and Rader who describe a series of propellers....
Waist high. That way you can still brace yourself while fishing, but can lean over to gaff a fish.
Yes, indeed. But it is my understanding that peak power is usually rated at or near max max RPM (5500 or so) while peak torque is usually quite a...
Another option is to use a 3 way ball valve. You can plumb it somewhere near the engine where the lines from the two tanks converge. You just swap...
Does anyone know where I can find data for the Gawn series? I have the following citation but can't seem to find it anywhere on the internet paid...
This is an unnecessarily combative reply. I did a calculation right there in the post and then qualified it with an "I think" because I...
Yeah. The duty cycle will only be about 10 minutes per hour, and I really don't care if I have to change the oil every 2 hours or something. I'm...
I'm converting a small gas outboard to high speed electric. Yes, a proper gear ratio would do it, but the outboards in the size range I need...
Hi there, I'm trying to figure out what generally causes lower unit failure with the goal of running a lower unit at higher than rated RPM. I get...
