Yes indeed, I met Chuck Piper early 70's at the RRI 'Perkins' test
facility in Sacramento,he was the lead man of our group and fabricated most
of the hardware, I machined some nozzles in my high school machine
shop,(throat diameter 2.25"). The photo on the front cover of his book was
called a Tar Baby, an end burning 5" motor of 350LbF for 16sec. Also a
surplus HIVAR truncated for the correct burn time at 1.5 in/sec,Pc 2-3Ksi,
Dt = 0.315". Ray Goodson introduced HTPB to our group about 1978 which led
to the very successful 3,4&5" nozzles motors. We flew both systems until
the early 80's when we abandoned Perkins and purchased the 320 acre Adobe
Rocket Ranch 50 miles east of San Jose. We never flew again.
