Now that summer is here, parents need all of the activities that they can find, so I thought I would share one of my favorite pastimes, model rockets. I used to love going to the park and launch model rockets with my friend and her dad when I was a kid. I don’t know what was more fun; building the rocket or launching it. Model rockets can take just a few hours or several days to build, so they’re a great project to do as a group. And even though pressing the launch button is a lot of fun, the whole family can enjoy a rocket launch.
Here’s a list of all of the items you will need to get started making and launching model rockets.Y Of course, you can buy complete starter sets, like this one, but not all of them come with all of the supplies you will need (especially for multiple launches).
A Rocket
Well, this is kind of obvious, I know, but picking out a rocket isn’t. If you’re just getting started, stick with a beginner or intermediate rocket for older children. Make sure that you pick a rocket that matches your needs and wants; don’t simply buy based on looks. You can usually decorate a rocket however you want, but decals and other items are usually included. Also check the recovery method that comes with your rocket; you may need to buy additional parachutes for multiple launches.
Motors
The type of engines used will determine the maximum height the rocket can attain, but their size, shape and composition is mostly the same across all motor types. Rocket motors are classified by a two or three letter and digit code combination; the impulse (usually between A and E) is the first portion, the thrust (1-10) is next to the letter, and the delay is the final number. Most rockets will identify an appropriate motor range, while beginner rockets are usually extremely specific. If you are really into this hobby, you can also buy a re-loadable motor kit and simply refill it for each launch. This option does require a little bit more skill and finesse.
Launch Controller
An launch controller will allow you to set off your rocket with the removal of a safety key and push of a button. Most ignitors come with a few ignitors - the fuses that connect the launch controller to the rocket and start the chemical reaction that sets the rocket off. Just like a motor, you will need a new ignitor for each launch. Not all starter kits include ignitors, so check before you head out to launch.
Launch Pad
Launch pads usually provide a thin metal pole that the rocket can be strung on to ensure a straight launch. They also elevate the rocket off the ground and protect the ground from getting burned. It is possible to launch without a launch pad, but it is discouraged, especially for beginner users.
That’s it for now. Next time we’ll look at more advanced rockets and parts.
