Hey folks. I've been lurking here for some time, but this is my first post.I wanted to share with you the cherry in my collection, an Apollo Block 1 Command Module Flight Director/Attitude Indicator. I picked it up on eBay a few years back. I assume it was used in a simulator rather than flown. It's a beaut on the outside, but on the inside, it's a work of art. |

These mechanical wonders are as much art as engineering. Thanks for the nice photos.------------------ John Fongheiser President Historic Space Systems, http://www.space1.com |

Yeah, they really are. Today's digital devices are astounding technologically, but to me they just don't have the same beauty as the old analog tech.------------------ B.J. West http://www.BJWest.net http://www.KelpEntertainment.com |

Look out man, you are getting awfully close to gimball lock! Just kidding, very nice piece for your collection there. I recall the eight ball gave a lot of headaches to the designers until they came up with a design that would work in Apollo. |

Does the red area around the pole signify gimbal lock? |

Yes, according to the info on page 32 of this PDF available from NTRS, the red area is a Gimbal Lock Region. |

Yeah, and contrary to what Jay is saying, we're far from gimbal lock, about 90° away. |

Heh. It depends on which picture you are looking at. In the first two pics, it's getting very close. In the sixth pic, you are absolutely right!Because it's visually interesting, I was gently turning the ball to show the gimbal lock warning spot in each photo. When I did, I could feel many gears whirring inside the ball! I'd love to see what all is going on in there, but I'm not brave enough to take the FDAI apart any further than I already have. |
