1. PII + activites at ATL– Ten assembled actuators (PII +) and one set of

manufactured parts made at Avasarala Techologies Ltd., Bangalore, India (ATL)

– Functional tests conducted at works of ATL at Bangalore

2. Brief overview of actuator activity in India.– Summary of efforts at ATL.

Learning from ATL. ATL noted that some hole dimensions were missing in the SAT Housing drawing. TMT noted and corrected the drawing

ATL also noted some missing dimensions and wrong dimensions in other drawings like that of Connecting Link, Upper Connect Block etc. TMT noted and corrected the same.

While assembling Connecting Links and Copper plate, ATL found centre to centre distance of holes i.e., 93mm of Copper Plate was not matching with the Connecting Links. TMT checked and changed the dimension of Copper plate.

A fixture for assembling the magnets was designed and made by ATL which enables magnets to be assembled for an actuator by 2 personnel in 20 minutes.

Schedule– Delay in schedule in first et of parts and 2 assembled

actuators.

– Delay due to non-availability of certified material in small quantities and also technical problems encounterd in casting.

– Problem encountered in obtaining bought out items from McMaster

– Schedule for second stage-manufacture and assembly of 8 actuators-ahead of planned period
