Week Thirteen –
Final Project Planning
Knockdown Warning
Indicator
A device that interprets
combined inputs of wind speed and vessel angle of heel in order to predict risk
of knockdown in squalls of 30, 45 or 60 knots, comparing the data against a series
of squall curves from the vessels pre-launch stability tests.
Components:
á
Wind
speed Indicator – DC motor with 3D printed anemometer.
á
Angle
of heel indicator -
step response with liquid in a molded shape (more of a c shape
á
Controller
board – interprets the above inputs against squall curves in the form of
a matrix and determines risk.
á
LCD
display – displays the above inputs, and (wind speed and angle of heel)
and the knockdown squall rating
á
3
x LED display ( one for each squall range)
á
housing for board, LCD and LED displays – lasercut press-fit acrylic.
á
Bus
network.
Nice to have:
á
Hello.radio network betwen input devices
and controller board – may use Xbee if this is
problematic, otherwise bus
á
Computer
based user interface that allows tweaking of the interpreted data (sail plan,
point of sail etc)
á
Illustrative
model
No additional materials
required
Work will be completed over
the next four days.
