In attendance: Dr. Matveev, Andy Wekin, Nathan Klosterman, Casey Harman, Jeff Kensrud, Luke Walden, Nate (Jeff housemate).
We discussed a variety of hull designs and accessories;
- Foils
- Surface piercing will have problems with cavitation
- Better foils than Clark Y exist
- There are optimum locations for rear foils due to wave from front foil
- Retractable Step on hull (morphing hull)
- Pulse Width Modulation
- By pulsing the power to the motor, better battery life can be achieved. (DC signal is changed from analog to digital)
- Prop Pitch
- Optimized for motor
- Gearing for drivetrain- optimize prop speed and motor speed
- Air Cavity
- air is forced into a built-in cavity in the hull. Lowers drag
Also, Tuesday and Wednesday the 120 class is having a club exposition day, August 29th and 30th at 6:30pm. We will meet here at 6pm.
