Further work carried out of the Ward Leonard shelf frame, mainly corrosion treatment ready for filling areas of wasted metal and priming.
Following an extended period of the simulator being U/S it is now serviceable again. A faulty co-processor was found to be the problem. See the accompanying photo of the simulator back in action. A major task now facing us is the repair of Argus computer boards, work has started on various test rigs but it is early days as a lot of work has to go in to reverse engineering designs etc we have no test rigs or test specs.
Away from Cosford work has continued on refurbishing our spare fan tray for the Argus computer. Several of the original fans have now failed which is not surprising as they are now 30 years old and the damp environment they have been exposed to. See accompanying photo of the underside of an Argus fan tray. The original but corroded finger guards are also being replaced, the photo shows one of the originals has yet to be changed. The original design and positioning of the finger guards caused a problem, spot what the problem is on the accompanying photo.
The T86 rear cabin floor had been primed the previous week, see accompanying photo, so on Saturday the task was to replace the plywood floor. The plywood sections had been cut out previously and laying them in position was a bit like a giant jigsaw. A start was also made on bolting the floor down.
Preparation for painting the rear cabin wall of the T86 has started, see accompanying photo. The cabin wall needs to be painted before the Ward Leonards are put back on their shelf. Further work was carried out on fabricating the mounts for the Ward Leonards and they were also primed.
Some time was spent on investigating the fault that is preventing the simulator from running. Fault finding will continue this coming Saturday. We do have spares but the issue is we have no way of knowing if they are serviceable due to age, their history etc and we have no test specifications for these comlpex cards. Testing cards in situ is an obvious answer to this problem but insert a card and it appears unserviceable, leave it a month of so, insert it again and it’s working. Next time we run up the LCP its not working; very frustrating.
