TMT Committee Certifies 29mm & 54mm AeroTech Reload Adapter Systems
AeroTech Information Release
4/13/10 Tripoli Motor Testing Committee Certifies 29mm & 54mm AeroTech Reload Adapter Systems The Tripoli Motor Testing Committee (TMT) of the Tripoli Rocketry Association (TRA) has certified 29 & 54mm reload adapter systems (RAS) for use with AeroTech's RMS reloadable motors. The 29mm RAS is currently certified for use with the 29/120, 29/180 and 29/240 cases. The 54mm RAS has been certified for use with the 54/852, 54/1280, 54/1706 and 54/2560 cases. Additional certification of the systems for use with the 29/360 and 54/426 cases is pending. The RAS allow the use of shorter (lower power) RMS reload kits within a specific motor casing, reducing the number of cases necessary to fly a wide range of AeroTech reloads. The RAS consists of three components: A "floating" forward closure that can be positioned anywhere inside the length of an RMS casing; one or more tubular "case spacers" that sit immediately forward of the closure; and a threaded retaining ring that holds the assembly together. The standard retaining rings have a large opening that permits the ejection charge end of the floating forward closure to protrude beyond the end of the case when no case spacers are being used. The floating forward closures have been designed with deeper ejection charge wells that accept heavier weight ejection charges and also allow the placement of the ejection charge cap within the well instead of only on top of it. Existing AeroTech reload kits can be loaded into RMS motors using the RAS with no modifications necessary. All reload kit parts are used in their familiar positions and configuration. The primary advantage to using the adapter system is cost. Consumers will be able to fly reloads spanning a range of four or more cases by using only two RMS casings. This translates to a hardware savings of $48 for the 29mm motors and $200 for the 54mm. A slight disadvantage is that 29mm motors loaded with the RAS will be approximately 1.77" longer and 28 grams heavier per case spacer used, and 54mm motors will be 3.34" longer and 109 grams heavier per case spacer. AeroTech is recommending a maximum of two case spacers be installed in a particular motor for ease of assembly, but there is no technical reason why a larger number of spacers could not be used. The 29mm RAS (P/N 29RAS) will be sold as a package which includes the floating forward closure, two standard case spacers, one extended case spacer (for use only with the 29/360 case) and a standard retaining ring for an introductory price of $29.99. The 54mm RAS (P/N 54RAS) package includes the floating forward closure, two case spacers and a standard retaining ring for an introductory price of $49.99. Optional “anchor” retaining rings for both systems may be made available as a future release. AeroTech is now taking dealer pre-orders for the new 29 & 54mm reload adapter systems and deliveries are expected to begin in about 4-5 weeks. Customers are encouraged to place orders early since consumer demand for the new reload adapter systems is expected to be high, as it still is for the 38mm RAS. Illustrated instructions for the 29 & 54mm RMS reload adapter systems are available for download in PDF format from the Resource Library on the AeroTech website at http://www.aerotech-rocketry.com.
