Water Rocket Challenge

The team must design their own water rocket (minimum 2) and launch pads with safety. Commercial water rocket kits and launch pads won’t be allowed. Following specifications and rules address many well-known safety issues of water rockets, but are not expected to cover all design possibilities.

Rocket Material:

• The weight of empty rocket with empty fuel tank must not exceed 0.5 kg (11 Pounds)
• The maximum allowed total height of the rocket is 76.0 cm.
• The rocket shall be made of low-density materials such as paper, plastic, duct tape, and glue. Use of Metal, ceramics, and other high-density materials are prohibited.

Rocket Nose Shape

While a sharper nose improves aerodynamics and accuracy, for safety the nose must be somewhat rounded and made of a soft, flexible material. The nose must definitely not form a sharp, hard point. It should not break a windshield or injure anyone

Fuel Tank

• The water-fuel tank must be a plastic soda-bottle, not a water bottle, with a maximum size of 2.5 liters. A soda bottle makes an ideal fuel tank for a water rocket; the bottle should be strong, light-weight, and designed to be pressurized.
• The rocket fuel must be water, driven by pressurized air to produce thrust. Water and air are non-toxic and non-combustible, and readily available. Air pressure must not exceed 70 psi, roughly 1/2 of the burst pressure of soda-bottles.

Launch Pad

The Launch pad must be of sufficiently sturdy construction to ensure a repeatable, predictable launch direction. The pad may optionally include a blast shield that disperses the rocket exhaust, a high velocity column of water, into a harmless spray, to protect participants and spectators and to prevent mud splatter from the dirt surface of the infield.

The Field area of the water rocket tournament would be 100 meters X 100 meters (approx). A fixed spot for the launching pad will be marked on the competition field. The penalty area is marked by white lines. Rocket is considered to have made a penalty if it falls outside the defined area.

Prior to the start of a Competition, launch pad and rockets should be made available in designated area. Specifically. Launches will be coordinated by a captain of the team. To begin, a team will raise a “pressurization in progress” flag and will fuel and pressurize their rocket, allowing a Launch Inspector to verify launch pressure if requested. When a team is ready to launch, they will raise a “ready to launch” flag and, if required, team captain will notify the referee in person.

• Maximum time allotted (Game time) for a team to setup and launch the rocket is 10mins. Failing to which will result in the disqualification of the team.
• Each team will get three chance to launch the rocket and achieve the maximum Air Time.
• Referee will record the Air time of the rocket for each attempt, maximum Air time will be chosen from all the attempt and will be declared as the official Air time of the rocket.
• Rocket with the maximum Air time will be nominated as the winner.
• Referee’ decisions in regards to the outcome of a challenge is final and binding upon all Competitors. Referee’ decisions are not subject to challenge or appeal.
