weight on turret floor

turret weight distribution

11feb04

The weight and positions for the objects on the rotary floor were obtained from ecastro on nov03 and used to plot the weight distribution on the rotary floor. The distribution was updated to the configuration when alfa is installed. The radii used for the position of the objects was eyeballed from the drawing. Some of the weights provided were approximate values (noted in the table). These weights do not include the weight of the floor structure or any temporary things placed on the floor (pumps, people, etc.).
The figure shows the weight distribution by turret position. Each object is identified by a symbol and color.

Fig 1 top: Each object on the floor is plotted with its weight vs its turret position.
Fig 1 middle: The weight is averaged by turret position quadrant to show the imbalance in weight distribution. The total object weight is 5170 lb..
Fig 1 bottom: The 1st moment (mass*radius) is computed by quadrant (you can divide by 32 to get slugs if you really want...)
On 14feb04 the turret floor was weighed (before the 6 to 8 Ghz receiver was installed). The floor was lifted with jacks and the load was measured. The total weigth (including the floor itself) was 9200 lbs. With the 6 to 8 rcvr it should weigh 9450 lbs. The maximum allowable weight is 10000lbs (i think the support springs on the floor are rated for 8000 lbs).

A table with the weight distribution is given below. The name column is the label used on the plots above. The turret position is that of the receiver or read off of the drawing. For the radii i took the focal circle for the receivers. For other objects i read an approximate value off of the drawing.

name	weight (lb.)	turpos (deg)	radius (inches)	notes
ifloR	461	5	30	right iflo rack. This is 1/2 the sum of the 2 racks. I don't know if the 2 weights are equal
ifloRBox	50	5	40	box attached to ifloRight Rack
alphaMot	50	0.	85	alpha motor
alpha	1500	20	71	alpha receiver. This is the value quoted by csiro. It may balloon up another 400 lb. after the mounting and snake is included.
sbtx	150	62	71	sband tx
sbtxwvgd	50	62	71	sband tx wave guide (this is a guess). It should also include the weight of the water for cooling.
sbtxMfld	50	62	90	sband tx manifold
sbnRcvr	337	76	71	sband narrow receiver.
sbwRcvr	244	104	71	sband wide receiver
sbhRcvr	150	126	71	sband high receiver updated 20jun13 from denis meaurement in lab. was 103lbs.
6to8Rcvr	250	160	71	6 to 8 ghz receiver.
ifloL	461	175	30	left iflo rack. This is 1/2 the sum of the 2 racks. I don't know if the 2 weights are equal
ifloLBox	50	175	40	box attached to ifloLeft Rack
610Rcvr	85	180	71	610 Mhz receiver
cbmodules	50	180	71	cband,610, 6to8Ghz modules are in this rack.
cbRcvr	254	207	71	cband receiver.
430Rcvr	221	252	71	430 Mhz receiver
lbwRcvr	500	287	71	lband wide receiver. There was a ? by this weight on the drawing so i don't know how accurate it is.
xbRcvr	221	310	71	xband receiver. This is the new position for the xband receiver. The move should occur in jan04.
327rcv	83	340	71	327 Mhz receiver.
