Problem Statement

    Design and fabricate a single stage water rocket using a plastic container preferably a softbottle that uses a combination of pressurized air and water for propulsion tocomplete 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 equalto 2 litres.
    2. Only water can be used as propellant. No other gas is allowed tobe 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 0launching (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 thelaunching of the rocket.
    6. No component or body part of the rocket should get detached from main frame duringthe flight of the rocket. If detached, 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 onthe nose of the rocket.
    3. Be careful while experimenting with water rocket. Use of excessive pressure might lead to an 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. The task is to cover maximum horizontal distance.
    2. The place where rep tip will fall will be considered for scoring.
    3. Two heats will be given to the participants and the better of the two horizontal distances (in meters) will be considered as score.
    4. Participants are allowed to use different rockets for this round.
    5. The teams that successfully cross 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 heats 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.

    Scoring Total= Round 1 Score + Round 2 Score
    Team size: maximum four members in a team, students from different educational institutes are allowed to make a team.
    Certificates will be given to all the participants.


Disqualification

    Any of following if satisfied may lead to disqualification of a team:
    1. Rocket found dangerous by organizers and judges.
    2. The Rocket don’t have a triggering safety launch from a distance of 1m from the launcher.
