| Description |
Rare Block II Apollo Rotation Hand Grip Controller, as mounted on the Command Module couch at work. The function of the hand controller was to adjust the attitude of the spacecraft during flight. For instance it was critical to the maneuver designed to withdraw the Lunar Module from the S-IVB stage of the launch vehicle once leaving earth orbit. This maneuver involved 180 degree rotation of the Command and Service Module to align with the Lunar Module in storage. It was also essential for the alignment of the spacecraft in the proper direction for any thrusting maneuver. This joystick is used for controlling spacecraft attitude, and the handle pivots at the palm for pitch up/down, through the center of the handle for yaw left/right, and inside the housing for roll left/right. Lever switches at the front lock and unlock the joystick for operation, and there is a spring-loaded button at the top of the handle. An amazing example combining both mechanical and electrical components, demonstrative of the craftsmanship and precision used in the manufacture of Apollo spacecraft parts. See what it looks like inside in the comments below. Controller housing measures 7.25 x 5.5 x 3", and is labeled on the face “1,” with its attached umbilical measuring 13.3″ long. Also referred to as an attitude controller or rotation hand control, this was used for controlling the spacecraft attitude. Handle pivots at the palm for pitch up/down, through the center of the handle for yaw left/right, and inside the housing for roll left/right. Levers in front of the handle lock the handle or unlock it for operation. The trigger switch which would activate the astronaut’s headset. Modified with “internal mechanical interface material changes to preclude stress corrosion.” (Rockwell specification ME901-0704-0802). Honeywell identification plates to one side identify part as “Rotation Control, Honeywell Part No. CG166H8, Rockwell spec. ME901-0704-0702, Serial No. 10028AAK1060, Manufacture Date 10 June 1969.” Modification Identification: “Honeywell Part No. CG166H9, Rockwell spec. ME901-0704-0802, Acceptance Date 6-15-73.” Joint connecting to the housing has its Beta cloth cover, with plastic tag labeled “P1,” other end retaining its protective metal cap. |
