Rocket Gallery   This section contains the technical specifications of water rockets built by the Air Command team. They are arranged roughly in order of development. Rocket variations refer to a typical rebuild of the same rocket. A rebuild is generally due to either damage to the rocket after a hard landing or an added feature. AC #1 AC #2 AC #3 AC #4 AC #5 Clobrda AC #6 Little Man Brotanek Cena John John TNT Jordan X-21 Spek D.Y. Clifford OO Frankovka J4Y Acceleron Polaron Tachyon Hyperon Graviton Gluon Axion Baryon Neutrino Photon Pod 1 Shadow Inverter PETOne Dark Shadow L1ght Shadow Rocket Naming The first few rockets did not have names, and were later designated AC #1.. AC#5. Then we used kids nicknames, and a few others. With Acceleron we began using sub-atomic particle names for the rockets. We try to choose the subatomic particle that reflects something unique about the rocket. Acceleron - is used to accelerate upper stages, Graviton performed our zero g-experiments, Gluon was our first use of glue in rocket construction, Neutrino is a small rocket, the Photon rockets are fast. etc. Click the image below to view a comparison of the rocket sizes, or scroll down the page for full details and photos.

Clifford

Clifford Clifford Clifford Clifford ( left most ) Variations: None Entered Service: 2nd October 2006 Capacity: 1.5 L Nozzle Size: 9mm Fill Volume: 480 ml Dimensions: Length: 580 mm, diameter: 95 mm Launch Pressure: 140 psi Dry Weight: 162 grams Recovery: Parachute using the NOAA technique. Current Status: Retired Notes: This rocket was named after Clifford the Big Red dog - one of the kids favourite characters. At the time this was our longest flying rocket without a parachute ( parachute failed to deploy) This one went very high. This rocket also used the same fin design as D.Y. A characteristic of the rocket was the weighted pointy nosecone. This rocket also had the base heat treated to narrow it so the nosecone could be made aerodynamic. This didn't work too well as the rocket stretched again under pressure, preventing the nosecone from releasing. It currently holds our flight time record of 48.2 seconds.

OO

OO ( I ) ( fourth from the left ) OO ( I ) OO ( II ) OO ( II ) OO ( II ) OO ( II ) Variations: I  and II Entered Service: 13th August 2006 ( I ) 20th August 2006 ( II ) Capacity: 2.5 L ( 2 x 1.25L ) - 6mm Robinson coupling Nozzle Size: 9mm Fill Volume: 750 ml Dimensions: Length:  mm, diameter: 90 mm Launch Pressure: 80 psi ( I ) 140 psi (typical) 150 psi (max to date) ( II ) Dry Weight:   Recovery: Version I and II used a single chute NOAA. A number of flights were flown with twin chutes. Current Status: Retired Notes: This rocket used to hold Air Command's flight duration record of 31.5 seconds. This is a very successful rocket for us. It has performed very well over a great number of flights. Version I was the first rocket that used flat fins as opposed to the normal ring fin. The rocket was quite unstable, but may have been due to a faulty nozzle. Version II had the fins lowered on a ring fin. This rocket also holds the highest pressure rocket launched by us at 150 psi.

Polaron IV, IVb, V and VI uses a single 1.15m diameter parachute. Deployed by version 1.3.2 of the flight computer. Polaron IVd used NOAA. Polaron VIb, VII, VIIIx, G1 used version 1.6 of the FC Polaron G2 uses new in-line deployment mechanism with fiberglass nosecone. Polaron G2b uses side deploy controlled by V1.6 FC, with back up parachute controlled by ST II with MAD Current Status: Active Notes: ( I ) Flight computer and fin section taken from Frankovka. This rocket never flew as it had a major malfunction on the launch pad. One of the bottles severely distorted and the coupling leaked. This rocket is equipped with a small digital video camera. Polaron II had one bottle removed, and new fins fitted. Polaron III was completely rebuilt after Polaron II crashed. All new bottles, new couplings, new payload section with a second chute. New plastic fins attached by large rubber bands. Polaron IV is newly rebuilt. Special features include: Top bottle is inverted to allow filling from top. Reinforced bottle bottoms with another bottle. FlyCamOne V2 video camera Z-log altimeter. Polaron IVb is identical to version IV except for new removable fin set to support the boosters and has launch lugs for the guide rail. Polaron IVd was a dummy rocket designed to test the booster system in place of the actual rocket. Polaron V has had an extra 2L bottle added. Designed to fly with Gluon II boosters Polaron VI has a new body constructed from 3 spliced pairs and using two 22mm tornado couplings. Those are Robinson coupled to the lowest 2L bottle from Polaron V in order to generated foam using Jet Foaming. Polaron VIb is a complete rebuild of Polaron VI, with a larger fin set, slightly larger nozzle and a new nosecone. Polaron VII was used to test re-enforced spliced pairs in flight. Polaron VIIIx was used to fly the first MicroLab experiment. It was built from the remaining bottles used on Acceleron V. Polaron G1 was reinforced with two layers of 200gsm fiberglass. Polaron G2 was our first large scale - high pressure rocket. Polaron G2b CATOed at 250psi on first attempt.
