Model Forum / General / Rockets / March 2007

The National Association of Rocketry (NAR) Standards & Testing Committee
has certified a new endburning motor using AeroTech's Warp-9
propellant, the G69N-P (P/N 07069P).

The G69N is the most powerful solid propellant motor available without
an ATF Low Explosives User Permit (LEUP). Designed for AeroTech, Dr.
Rocket and Rouse-Tech RMS-38/120 hardware, the G69N produces a
certified total impulse of 137 N-sec with a burn time of just under 2
seconds. The delivered specific impulse (Isp) of the G69N is 224 seconds.

The G69N's exceptional performance was achieved through a combination of
design features, including the use of 62.2 grams of high efficiency
Warp-9 propellant with a constant burning surface area, high chamber
pressure, high expansion ratio and a "bell"-shaped nozzle.

Warp-9 reloads are currently sold in a plugged configuration and rockets
using them must employ a timer, altimeter or radio-actuated recovery
system. The AeroTech EFC-1 Electronic Forward Closure is perfect for
use with the G69N when combined with the EFC38-1 motor closure.

The G69N reload kit will be priced at $19.95 each. No user certification
is necessary to purchase the G69N, though customers must be at least 18
years of age. AeroTech is now accepting orders for the new G69N reload,
and shipments to dealers will commence shortly.

An assembly drawing, instructions and the NAR certification document for
the G69N are available for download in PDF format from the AeroTech
Resource Library at http://www.aerotech-rocketry.com.
