3…2…1…Blast off! Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the engineering uses of fluid properties. It’s time to put this theory to use in making the water equivalent of a space rocket!

Task:

This competition requires you to build a simple water rocket from plastic bottles that use water and compressed air as the propellant. Thus, using hydraulic and pneumatic forces, the task is to propel rockets to a long range with a high degree of accuracy. You don’t have to be rocket scientists to participate here but you could do your best to ape our space engineers!

Gameplay:

Round 1 –

Range of the rocket will be the criteria on whichthe team is judged. The final points will be calculated as: Points = Maximum Range Travelled

Round 2--

Precision is the criteria on which the team will be judged. There will be 4 circles and the teams have to attempt maximum points in 2 shots. maximum points taken will be the winner. The tentative arena will be as shown below.

Points:

20 points for innermost circle

15 points for second last circle

10 points for third last circle

5 points for outermost circle

0 points for missing all 4 circles

Rules:

- The range will be the minimum distance taken from the launcher to the point where the rocket hits the ground.

- The angle at which the rocket is to be launched can be decided by the participant.

- Launcher will be provided at the spot. However, if any team wishes to use their own custom launcher, they are allowed to do so as long as it is a fixed launcher.

- Attachments to enhance the rocket’s capabilities such as fins, wings and parachutes are allowed. In such a case, teams may be required to make their own suitable launcher.

- The rocket should be purely mechanical. Any type of motors or chemicals will not be entertained.

- The optimum amount of water to be put into the rocket is left to the participant.

- A single trial will be given in the first round.

- The same rocket must be used for all the rounds. Although minor modifications to the

rocket may be made between the rounds but the body of the rocket has to be the same in all the rounds.

- Maximum no. of participants per team is 4.

- If second round ties ,first round score will be

considered.

Specifications:

- Maximum size of the bottle is 2.25L.

- The working fluid allowed in the rocket will only be water, provided at the venue of the

Competition.

-          The water will be pressurized with the help of a foot pump that will also be provided.

Disqualifications:

Any of the clauses below if satisfied may lead to disqualification of a team:

- If any rocket is found to be dangerous to launch by the organizers and judges.

- If a rocket blasts before the launch.

- If a rocket launches before indicated by the organizers.

- If any part of the rocket breaks off from the rocket during the flight.

- If any readymade models are used.

- If any design rule is not abided by the participant.

- The organizers reserve all rights to change anyof the above rules as they deem fit. change in rules, if any will be indicated on the website. In case of any discrepancy decision of the judges shall be treated as final and binding on all.
