WATER ROCKET CHALLENGE:
The competition area has is a special place defined for the rocket’s operation (hereafter COMPETITION FIELD).
At the competition, each entry must pass a visual inspection and height requirement in order to be eligible to compete. Entries that fail inspection will be given ONE opportunity to make modifications to pass inspection prior to the beginning of the water rocket launching competition.
The rocket will be launched at an angle of approximately a 90 degree using 355 ml (milliliters) of water and 70 psi of air pressure. The “hang time” of the rocket will be measured using a stopwatch. Launch angle will be kept the same for all rockets launched at the competition.
The “hang time” is defined as the time from the point when the rocket leaves the launch pad until the time it reaches the ground or strikes an object. This measurement will be recorded by at least three qualified judges, with the average “hang time” used to determine the final “hangs time” score.
The final score for hang time will be calculated based on the maximum hang time recorded during the competition, using the following formula:
Average hang time (sec) X 100 Maximum hangs time
Definitions
Hang time: There are optical sensors that detect the rocket’s start and stop movement. When the rocket take off from the launcher, the timer automatically starts to count the hang time. As the robot reaches earth, the timer automatically stops and the recorded time value is saved.
