I stumbled across the announcement just now and thought this would be a good place to include it:
News from the Tripoli Motor Testing Committee:
Subject: new nozzles for 3 AT Reload Kits
Aerotech has announced their intention to replace the ‘medusa’-style nozzles in three 75mm reload kits with single-throat phenolic nozzles. These single-throat nozzles are configured to give the same Kn as the previously used medusa arrangement. The motors involved are the K560W in the corresponding CTI case, the K1000T, and the L1150R, both in Aerotech cases. The TMT committee has reviewed in-house testing data and seen no significant difference in any performance metric and has extended TMT certification to reload kits incorporating the new nozzles.
These reload kits will be offered to the public with new instruction sheets.
