Hi Brad,

I gave you some of these in the 5/12 B600 controller email:

i) Flap Units Panel:
	1) Dynamic stroke on each flap is +/-12 degrees.  Static stroke
	   is asymmetric, but less than +/-13 degrees.
	2) ADT full scale is +/- 30 degrees at 100mV/degree.
	3) Please change Actuators labels to #1, #2, #3 instead of A, B, C.
	4) Maximum upper flap velocity is about 43 degrees/sec.
	5) Maximum upper flap torque is about 345,000 N m total, or
	   115,000 N m per actuator.
	6) Maximum upper flap acceleration is about 300 deg/sec^2.
		7) Maximum lower flap velocity is about 17 degrees/sec.
		8) Maximum lower flap torque is about 2,361,000 N m
		   total, or 787,000 N m per actuator.
	9) Maximum lower flap acceleration is about 63 deg/sec^2.
	10) I don't know if you are calculation the maximum angular
	    accelerations based on the 8 g accelerometers at their respective
	    radii.  The maximum accelerations, velocities, and torques shown
	    above are the maximums based on the actuator areas, moment arms,
	    and inertias with water.


Here are the other values, which I also marked up on your hardcopy:

      11) Maximum Upper Actuator Force is 276,000 N total, or 92,000 N
	    per actuator.
      12) Maximum Upper Actuator Velocity is 1.0 m/sec.
      13) Maximum Upper Actuator Static Stroke is +282 mm / - 305 mm.
      14) Maximum Upper Actuator Dynamic Stroke is +250 mm / - 271 mm.
      15) Maximum Lower Actuator Force is 1,050,000 N total, or 350,000 N
	    per actuator.
      16) Maximum Lower Actuator Velocity is 0.70 m/sec.
      17) Maximum Lower Actuator Static Stroke is +501 mm / - 545 mm.
      18) Maximum Lower Actuator Dynamic Stroke is +467 mm / - 469 mm


These are the triangle leg lengths that I used for the design:

      19) Upper Actuator Pin to Pin Length at Vertical Flap is 2658.2 mm
      20) Upper Actuator Waveboard Length at Vertical Flap is 2372.0 mm
      21) Upper Actuator "Ground" Length at Vertical Flap is 1405.1 mm
      22) Upper Actuator angle to horizontal at Vertical Flaps is 69.09 deg.
      23) Lower Actuator Pin to Pin Length at Vertical Flap is 4158.5 mm
      24) Lower Actuator Waveboard Length at Vertical Flap is 4680.0 mm
      25) Lower Actuator "Ground" Length at Vertical Flap is 2250.7 mm
      26) Lower Actuator angle to horizontal at Vertical Flaps is 40.15 deg.


These are the accelerometer positions from the waveboard design.

      27) Upper Accelerometer Vertical Height to Upper Hinge = 2610.4 mm.      
      28) Upper Accelerometer distance to Upper Hinge = 2616.3 mm.
      29) Upper Accelerometer angle to Tangent of Rotation = 3.84 degrees.
      30) Lower Accelerometer Vertical Height to Lower Hinge = 3320.0 mm.      
      31) Lower Accelerometer distance to Lower Hinge = 3330.4 mm.
      32) Lower Accelerometer angle to Tangent of Rotation = 4.53 degrees.

Craig
