AeroTech to Re-release Long-Burn 54mm Reload Kits June 29, 2004 Web posted at: 7:07 PM EDT
Cedar City, UT (ROL Newswire) -- The AeroTech division of RCS Rocket Motor Components (RCS), Inc. is pleased to announce that it will soon be re-releasing its 54mm long-burn Reloadable Motor System (RMS) reload kits, which have not been manufactured since October 2001. These kits were extremely popular with high-power fliers due to their long burn times and their ability to be used in rockets of light weight construction and as upper stages. AeroTech expects that production and shipment of these reloads to its dealers will begin by the end of July.
Time-thrust curves for these reloads can be viewed on the Tripoli Rocketry Association website at:
These motors use a variation of the "Moonburning" offset-core grain geometry invented by Bill Wood in the early '80's. AeroTech's version employs a rectangular slot offset to one side of the propellant grain to achieve the extended burn time characteristic of the Moonburner design.
While the J180T uses the conventional 54mm RMS propellant grain diameter and phenolic liner, the J90W, J135W and K185W reloads utilize a slightly smaller propellant grain, outer phenolic liner and an inner paper liner to protect the casing from the extended exposure to hot combustion gases.
Suggested retail prices for these reload kits will be comparable to the prices of other AeroTech reloads that fit the same RMS hardware specifications. Extended length 54mm forward closures must be used with the White Lightning reloads to accommodate the longer delay columns that are necessary for these motors.
