The only dynamo experiments at present proceeding on Goshawk chassis are those in which short pieces of copper wire, carrying small pieces of fusible alloy, (melting at about 72°C) are clamped to the carcases to check the temperatures which they attain. This is fitted to the dynamos on 2GI, 3GI, 6GI & 7GI. In only three cases however are the main brushes retarded by the amount now standardized namely 3GI (dynamo R3) 4GI (dynamo 161, at W.W) and 7GI. (dynamo R1, not marked). Signed: (Contd) This Sheet must be filed on completion of the work. | ||
