How to Insert and Restrain an Igniter in a Composite Propellant Model Rocket Engine

www.ApogeeRockets.com - I was at a launch a few weeks ago, and a modeler that had never used a composite motor before came up to me and asked how to insert and then keep the igniter in the motor so it wouldn't fall out when the clips were hooked on the leads. This seems to be a common question, as I've shown lots of people this same information over the past few years.
In this video, you'll see three ways to hold the igniter in the motor, which seems to be the main concern that people have with composite propellant motors. Hopefully, this will help us all to experience fewer mis-fires at launch.

Klein electrician scissors are great for stripping the small gauge wire of igniters. They have a little V notch on the back of the blade that you pull the wire through to strip it. We use them all the time to cut and strip ematches when setting up fireworks displays. It’s a good crossover to model rocketry use.

Can you use a composite motor as a two stage on the main rocket will it ignite normally?

@apogeerockets 3 жыл бұрын

Nope. As the video stressed... you have to ignite the composite motor from the top. You can't do that using direct staging.

Do the economax f-class motors have ejection charges? if not how do rockets of this size eject thier parachutes?

@apogeerockets 2 жыл бұрын

Any motor with a number after the dash has an ejection charge. So yes. The economax motors do have a ejection charge.

How do you load the igniter into a Cesaroni Pro54 when the core is offset from the nozzle? E.g. a I100 Thank you in advance.

@apogeerockets Жыл бұрын

Just feel around with the igniter until it finds the hole. It isn't hard.

Maybe. There are two articles in our newsletter archives on how to make tubes - spiral wound and convolute wound. You can check those out in the mean time.

Isn’t this how they lit the Shuttle Boosters? From the top?

Will this work with a fuse? Or will it prematurely ignite the grain before reaching the top?

@apogeerockets 9 ай бұрын

NOPE! A fuse will be spit out of the nozzle by the pressure, long before it burns to the top where the motor needs to be ignited. You have to start the burn at the top, never the bottom.

@@Ikej873 The motor comes with one igniter. It is probably the First Fire Mini from Aerotech. If you visit our website, and find the motor's product page, it will always list which igniter comes with. That way you can buy spares if needed.
