1.Thrust is the water rocket event where one can show case rocketry skills and practical talent. 2.The event is held in three rounds spread over 2 days. 3.The no of teams shortlisted from initial round will be entirely dependent on the no of participants who appear for the event. 4.It covers various aspects of product making including design, model construction.
Certificates of participation will be given to participated teams.
1. Range covered.
2. Deviation from the central line.
3. Time of flight.
The objective of the preliminary round is to launch a water-rocket without any payload, and make it go as far as possible from the launch point i.e. the maximum horizontal distance.
The horizontal distance will be considered from the starting point to the point where any part of the rocket first touches the ground.
Each team shall be allowed two attempts to launch and the better of the two will be considered. (This may be altered later based on the performance of most teams.( Pressure limit for this round will be 70 psi )
Only 30 percent of the candidates appearing in the first round will be qualifying into second round which depends upon the score they get.(It depends on no of participants )
Round Two tests the accuracy of the rockets.
Each team will be having two chances.
The maximum score that a team can earn is 100 points in each round that can be scored by hitting the rocket on a particular point (ex - 80meter with some angle say 60 degrees) in the 2nd round. The points will be deducted as much is the deviation from the point. The better of two chances will be taken into consideration.
(Pressure limit for this round will be 70 psi )
Only 30 percent of the candidates appearing in the second round will be qualifying into third round which depends upon the score they get(It depends on the no of participants).
In this round, the teams whose rocket will remain in the air for maximum time will get maximum points. The participant can fill up to any pressure and release his rocket. The time of flight is calculated. The more is the time of flight more will be the points he scores. Only two attempts will be given to each participant in this round.
1.A team may consist of a maximum of 3 members.
2.Teams may use different rockets for different rounds.
3.The total capacity of the bottle maximum is 2.25 litres only.
4.The rocket must be built completely from scratch and not using model rocketry parts.
5.The pressure vessel must be made from commercially available nonmetallic soda bottles (PET bottles). Fins if required are to be constructed from lightweight non-metallic materials.
6.The rocket must use tap water as its primary reaction mass. Thrust must come from expelling reaction mass/water, not from air discharge.
7.Participants will be provided with tap water.
8.The angle at which the rocket is to be launched can be decided by the participant.
9.The organizers will not provide a launcher, so teams must bring their own launcher
10.The rocket must use compressed air as its energy source. A normal bicycle pump, as well as a foot pump, will be provided to compress the air. The size of the pump outlet will be the standard type available in the market. If your design has a different nozzle size, please be sure to bring your own nozzle and connecting pipe.
11.All parts of the rockets should be properly attached to the main body. If any part (fins etc.) breaks away during flight, it will compromise the safety of the spectators. Therefore, such water rockets may be disqualified from further participation at the discretion of the organizers.
12.Each team is strongly advised to bring two rockets of the same design (the second acting as a backup) in case of any damage .The organizers will not be responsible for damage suffered by rockets during the competition. Extra time shall not be given for remaking of damaged rockets.
13.Multi-stage rockets are not allowed.
1.The final judgment is based on the total points scored by the participated team in all the three rounds described above
2.The points are also given to the teams based on their creativity and
simplicity in making the water propelled rockets, this will be decided at the time of the event by the event manager by viewing their rocket samples.
3. The total points scored in all the three rounds are added up and awarded as their final score.
