This glossary contains some terms generally associated with water
rockets.

Description |
| Apogee |
The point at which a rocket reaches the highest
altitude. |
|
AR Booster |
The Air Reservoir Booster is a feature added to
launchers to increase their performance. The air
reservoirs supply high pressure air through the
launch tube to the rocket as the rocket is moves
along the launch tube. |
|
Blow-through |
A term referring to the effect where on launch the air
emerging from the lowest coupling punches a hole in
the water - blow-through - all the way to the
nozzle, this allows some air to escape and hence
dropping the pressure quickly inside the rocket.
This causes a rocket to under perform.
(see Flight Log Day 26) |
|
burnout |
A term generally used to describe the point in
time when the rocket stops producing thrust as
result of the internal pressure equalling the
external pressure. |
| FC |
Flight Computer |
|
Jet Foaming |
A technique developed to generate high density
foam inside a water rocket to alter the rocket's
thrust profile.
(see Flight Log Day 27) |
|
NOAA |
Nosecone - Off - At - Apogee. A parachute
deployment technique where the nosecone is suppose
to fall of as the rocket reaches apogee allowing the
parachute to fall out. |
| PLP |
PL Premium - a glue commonly used for splicing
bottles together. |
|
TDD |
Trevor's Deployment Device. This device acts as
a pressure switch for detecting when the pressure
inside the rocket drops back to atmospheric
pressure. This is the point at which the rocket
stops producing thrust. It is used to initiate
parachute deployment or staging mechanisms. |
|
Tornado Coupling |
A threaded hollow coupling that is able to join
two bottles neck to neck. Each bottle just screws
into the each end of the coupling. |
