To all,
I am pleased to announce new motors from Contrail Rockets, Thomas Sanders, Head Gas Man. Thomas continues to flesh out his 38 and 75 MM lines, with the addition of two more sparky motors. Of note is the 75 3200 S SP(arky) motor, with 10.5 seconds of sparks and a respectable 140 pounds of impulse to start, tailing down to 60# at 8 seconds, with a vapor phase from there.
Newly introduced is two motors in his 98 MM line. These are of the building block system, using combustion and pressure vessel bolt together construction. His 98 5300 XF BG motor rises to 1100 pounds of impulse, tailing straight off to zero at 2.5 seconds.
Thomas also introduces 5 motors in the debut of his 54 MM line. His 54 MM line are of U/C Floating injector, integral tank style and starts out with his Black Gold Propellant, also used in the 75 and 98 MM systems. It is also a multi port injector system of the same design as his 75 and 98 MM lines albeit with a forward closure vent. Of note is his 54 48 S BG system, a real nice 29% K motor with a 7.5 second burn time and with a peak initial of 100 pounds of impulse in a regressive straight line to 40 pounds impulse and vapor start at 6 seconds
The specific data is as follows:
Name, TMT, Size, Total NS, Burn Time, Ready Weight, Grams (without NOS)
38 MM
G234, G221 47%, 38 16 F HP, 117.95, .53, 544
