Rocket Information you can USE!

 

Here is some stuff for high powered rocketry

Homemade Simple Relay Launch Controller

First, is the schematic for my simple relay launch controller. This is a modified design from information I found on the web a few years back. It works for me, but if you decide to build it you do so at your own risk. FYI - This design will probably not work well if you use e-matches for igniters. The current from the 9 volt continuity check may ignite them prematurely.

NAR Level 2 Certification Test For Practice

Second is a simple online test I wrote that uses questions from the NAR test pool. These are from the 1999 test version. This is not the latest test version but it's close.

Reloadable Rocket Motors

Next, some info about rocket motor reloads. I can never remember what reloads go into what case. Except for the G64. So I use the table below quite a bit. Perhaps you may find this handy as well.

W - White Lightning White Lightning has a visible orange flame and lots of white smoke.
R - Redline Redline propellant has a bright red flame, and a little white smoke.
J - Blackjack Blackjack produces lots of black smoke and little, if any, visible flame.
T - Blue Thunder Blue Thunder has no smoke, a light purple-blue flame and a fast burn time.
N - Warp-9 Warp-9 exhibits a yellow-white exhaust plume with a minimum of smoke.
FJ - Fast Blackjack Fast Blackjack produces black smoke like a regular Blackjack, with burn characteristics similar to White Lightning.
G - Mojave Green Mojave Green exhibits a bright green flame, with a fast burn time.
X - Propellant X This is a fast burning propellant with a long yellow/white flame and low smoke.
ST - Super Thunder Super Thunder produces a brighter violet-blue flame with a little more smoke than Blue Thunder (T).
M - Metal Storm Metalstorm ignites easily and produces a large, brilliant white exhaust plume, a much longer yellow-orange dense spark tail, plentiful white sparks that fan out in flight.
DM - Dark Matter Dark Matter is a sparky propellant but unlike Metalstorm with it’s higher impulse and white smoke, Dark Matter is the black smoke sparky.
NT - New Blue Thunder This produces a beautiful blue exhaust jet studded with prominent “mach diamonds.” They say it's got a much more intense blue than the standard Blue Thunder.

Below is a table that outlines many Aerotech cases and the rocket motor reloads that fit into them.
