i need a 38mm endburn stylye forward closure. dose anyone know where i can get one i have been searching the sites looking for one and have not seen any different ones yet, i have the part no 38ebfcpt. i have sent a few emails off but if someone comes across this can you let me know.

Order  from aerotech.

ok from what i have read its just the plugged closure and if i could cross reference this part no i would have ordered it hotspot thats the first place i went for info. sent them a email to confirm this.

hey guess what i was half wrong about this closure turns out they are plugged but can not have a void at the end of the propellent there for they are plugged plugged..lol well i found one and cause no one could help me i am not telling you were.

The I59WN-P (P/N 09059P) is AeroTech's first Boost-Sustain offering and uses a coreburning White Lightning™ propellant boost grain coupled with an endburning Warp-9 propellant sustain grain. The I59WN fits RMS 38/480 hardware and delivers a NAR-certified total impulse of 486 N-sec over a burn time of 7.99 seconds. The motor delivers a peak "boost" thrust of 173 newtons followed by a long sustain burn tapering from about 60 to 35 newtons.

The I49N and the I59WN both require use of a new 38mm "endburning-style" forward closure, P/N 38EBFCPT. This is due to the fact that both reloads are sold in a "plugged" configuration with no delay components, and no void space can exist above the endburning propellant grain. The endburning-style forward closure is machined with a 5/16-18 threaded recovery system anchor point and also includes a threaded boss for attachment of the AeroTech Electronic Forward Closure (EFC-1).

if any one is looking for 1 of these you can find them at comonwealth displays. it seems odd that only the I49 and the I59 are the only motors that need these closures.

K270 has an extended forward closure.

yes i needed the 54mm extended forward closure last year for the J 90

well it arrived today so my wife says cant wait till i get home i have lots of goodies to play with on me break. i forgot to order a 54mm plugged closure dooh but i also got extra 38mm and 29mm closures and seal disc so i can prepare a couple of motors in stead of one at a time. more launches yay

well this is a 38mm end burn style closure

notice the thread at the end of the closure both internal and external

Thanks for the pictures Dazza some good information there.
