UKROC 2024

Information for schools and groups entering or thinking of entering the UKROC competition 2024. Within this information you will find a recommended shopping list as well as design considerations and helpful hints and tips.

The sky’s the limit!

Competition Information

The UK Youth Rocketry Challenge is a great way to engage the next generation of engineers with practical experience of building and executing complex missions. To read more visit there website UKROC.

So you have entered UKROC 2024 and now find yourself looking to design and build a rocket, dont forget to read the rocket requirements in the UKROC2024 Mission. We have what you need from body tubes to motors. Before you start shopping though you need a design, are you going to use BT-70 or BT-80 body tube? what fin design gives you the best stability and how high will this or that motor get us. The ideal way to prepare a design is using simulation software like SpaceCAD, Rocsim or OpenRocket.

Shopping List

So you now have a design and want to start building here is a list of things you might need;

Rocket Motors

You will find three types of motor on our website here is a brief introduction to each. You will find the approved motor list here.


This are black powder based motors and are single use, they come in packs of multiple up to a D12 (please note that the E and F Estes motors are not available to the UK market). These are typically 24mm in diameter for the D motor and cost effective if you are looking to cluster.

Aerotech Single use

These are a ammonium perchlorate composite propellant based motors in a single use form ranging from E to G in power. These are 24mm or 29mm in diameter. TIP: you don’t need to decide between the two sizes as you can always build to 29mm and use an adapter for use of the 24mm motors.

Aerotech RMS

RMS is a reloadable system of motors in 24mm and 29mm diameter, they range in power from D> but they do require a reusable casing in the correct size. These motors are for the more experienced flyer as they require you to put the motor together, there are typically a number of o rings, spacers, and grains. When putting these together always follow the instructions but be aware students will need to be able to do this at the competition unaided.

Considerations in your design to be aware of for 2024

  • The rocket must not exceed 650 grams gross weight at liftoff.
  • The overall length of the rocket must be no less than 650 millimeters (25.6 inches)
  • They must use body tubes of two different diameters in their external structure. The upper one which must be no greater than 2.25 inches (57mm) in diameter and the lower must be no less than 2.5inches (63.5mm) in diameter.
  • Each body tube must be no less than 6inches (150mm) long,
  • All parts of the rocket (other than disposable recovery wadding) must descend connected together under parachute.
  • Rockets flown at the Finals will be required to have a painted surface.

You are required to reach a height of 820 feet TIP: Keep the weight of your rocket down, use things like foamboard for fins for example, its easy to add weight later if you need to.

You need to carry an egg, how are you going to protect the egg? TIP: which part of the rocket are you going to put the egg in as it will add weight which you could use to help stabilise your rocket.
