Water Rocket Competition

The Water Rocket Competition is a new concept brought for students and for companies too. Since LiftOff is usually held during the Space World Week, the board has decided to combine the interaction between students and companies with space related workshops and activities.
This year we will have the first edition of this competition hoping that through the years it becomes a legacy.

To take part in the first Water Rocket Competition during LiftOff make sure to register your team before the 25th of September. You can do so on the this form. Make sure to carefully read the following rules before you register your team.


Regarding the teams:

  • Each team shall have a maximum of 4 members.
  • All of the team members must be students from space programs at Luleå University of Technology.
  • Each team shall register before 25th of September.
  • Each team shall present only one (1) rocket for the contest.
  • The teams shall provide a document explaining the design of the rocket. The explanation shall be no more than 1 page long not including pictures and drawings of the rocket showing the dimensions and materials used. The complete report shall be no more than 4 pages long. Pictures of the fabrication of the rocket are encouraged. This document shall be sent by the 25th of September. Team that do not provide this document will be disqualified.
  • Each team shall provide a CAD model of the design as a step (.STP) file, the design of the model has to be able to accommodate the altimeter that will be used during the competition. You can find more information about the altimeter here.
  • Each team shall provide a short video presentation of their project (2-5 min). In this video, the teams shall talk about the project, the process they followed and any insight they consider relevant as well as the finalized water rocket.

Regarding design, performance and launch of the rockets:

  • The water reservoir shall not be more than 2L in volume. The final filling percentage will be left to the team to decide.
  • Materials are restricted to plastic and glue. Plastic 3D printed parts are allowed and preferably should be PLA.
  • There is no limit on the empty weight of the rocket.
  • The geometry of the rocket is open, but make sure it can’t harm anyone (i.e. having a very sharp nose).
  • The rocket will be launched vertically.
  • The air of the rocket will be provided by a bicycle air pump attached to a small launch tower/station so make sure that the outer diameter nozzle is of similar size of a standard soda bottle.
  • The air will be pumped up to a pressure of 3atm (44 psi).

The winners will be announced on the second day of the event.
