1-2E Pitch Axis
Pitch Motor: A motor gearbox combination mounted to the left pitch shaft. Physically moves unit in pitch
axis. A key mechanically transmits torque from motor to the shaft. Filled with gear lube at the buildup of
the unit.
Pitch Brake: Mounted on the end of pitch drive motor integral to the unit. . It receives 220 VAC to the
rectifier inside the enclosure. The coil is a 220 VDC unit. It has a manual release lever.
Pitch Encoder: Is a 400 or 120 line encoder mounted to the motor shaft. Sends pitch position to the
computer via the interface board and motion control board.
1-2F Lift Axis
Lift Motor: Motor brake combination. Mounted at the right rear inner side of the A frame. Connected to a
90-degree gearbox via couplings and drive shaft. Drives, through couplings, the lift jack gearboxes at each
side of the base.
Lift Brake: Mounted at end of the motor. Controlled by a 220 VAC coil.
Lift Encoder: Mounted to the drive axle from motor to the ninety degree gear box. A 400 or 120 line unit
that gives height feedback to the computer via the interface and motion control boards.
1-2G Counterweight Drive System
Drive Motor/Brake/Gear box mounted on top of center weldment, attached to a horizontal drive
screw that moves the counterweight in either direction as commanded by the CPU.
Brake attached to end of motor, this is a 115 VAC controlled coil.
1-2H Pitch Slip Rings
These units are sealed no maintenance required or allowed.
1. Power Side: Located above the power cabinet right side on the end of the pitch
shaft. Feeds wires to the center weldment to the roll motor/brake and counterweight
motor/brake.
2.
Signal Side: Located at the end of the pitch shaft left side right before the pitch
motor. Feeds all the signals to the center weldment. Projector video, roll encoder
power and signal, HAPP box joystick signal on M/T3000, power to the cockpit area,
canopy sensor and occupant E-Stop.
1-2I Blowers
1. 4.5” blower mounted on pitch motor.
2. 3.5” blower for the projector.
3. 2- 4.5” blowers mounted at rear of cockpit for ventilation.
1-2J Power Strips
One left inner rear side of A-frame and one located under seats of the cockpit and one in base of command
console.
1-2K Sensors
One left upper limit sensor, one right upper limit sensor, one lower limit sensor, one canopy sensor and one
demo switch sensor.
1-2L Switches
There is one Occupant Safety Switch between the seats in the cockpit and one E-Stop switch on the side of
the command console.
