Aqua Jet

In Aqua Jet competition teams from various colleges compete with each other with their aqua jets which are water bottle rockets and the rocket is launched as a projectile and the rocket which achieves the maximum range is the winner. The air is pumped into the rockets through a hand or foot pump and then the rocket is launched. Each team is given three chances to launch their rockets and the best of the three will be considered as final result.

Aqua Jet

Problem Statement

    Design single stage water rocket using a plastic container preferably a soft. Bottle that uses a combination of pressurized air and water for propulsion to Complete a defined task. A launcher should also be constructed that could launch. The water rocket safely.


Design Specification

    1. The capacity of the plastic container to be used should be less than or equal To two litres.
    2. Only water and coke should be used as propellant. No other gas is allowed to be pressurised and provide thrust to the rocket. (foot pumps and hand pumps can be used).
    3. The maximum pressure should not exceed 60 psi.
    4. Only the above given propellant should be used for launching (Mentos can be used). No other potential, kinetic, or any other form of energy will be permitted for the launch.
    5. The launcher must remain stationary on the ground while and after the Launching of the rocket.
    6. No component or body part of the rocket should get detached from main frame during the flight of the rocket. If detached then the rocket will be disqualified.
    7. The flange and the mouth of bottle can be used to hold the rocket while pressurizing.
    8. Upper tip of rocket should be visible and marked red.
    9. No electronic device can be used.
    10. The launching mechanism should be such that participant is enable to launch the rocket safely from the launcher.


Safety Precautions, Hints And Tips

    1. To keep rocket more aerodynamically stable there is a rule of thumb that states that the centre of drag (COD) should be 1-2 times the distance equal to rocket diameter, behind the Centre of Gravity (COG). Where COD can be found by making a cardboard cut-out of the sideways view of the rocket and finding its centre of gravity.
    2. To lower COD you can use wings or to rise COG try using weights a Nose of Rocket.
    3. Be careful while experimenting with water rocket. Use of excessive pressure might lead to accident.
    4. Do not use mineral water bottles as they cannot withstand the high pressure. Use soft drink bottle.
    5. Do not use any metallic part in rocket as it can cause harm.
    6. Safety googles are advised to be worn by the competitors.


Rules

    Round 1 : Elimination


    1. Team size a maximum no of four members in a team.
    2. The task is to cover maximum horizontal distance.
    3. The place where rep tip will fall will be considered for scoring.
    4. Two trials will be given to the participants and the best of the two horizontal distances (in meters) will be considered as score.
    5. Participants are allowed to use different rockets for this round.
    6. The teams who successfully crosses a specified distance will be eligible for finals.

    Round 2 : Finals


    1. The task is to make the rocket land on the defined zones to earn maximum points.
    2. Two trails will be given and best of two will be considered as round 2 score.
    3. Participants are allowed to use different rockets for this round.
    4. Team with highest scoring will be declared as the WINNER.
    5. The teams who successfully crosses a specified distance will be eligible for finals.


Disqualification

    1. Rocket found dangerous by organizers and judges.
    2. The Rocket don’t have a triggering safety launch from a distance of 2m from the launcher.
    3. Rocket blast before launch.
    4. Design rule not abided by the participants.
    5. Rocket launches before permitted by the judges.
    6. The organizers reserve all rights to change any of the above rules as they deem fit. Changes in rules, if any will be highlighted on the website.
    7. In case of a discrepancy decision of the judges shall be treated as final and binding on all.
