    Using Side Thrusters on a missile to create an angular acceleration

    Assume a rocket is standing on the ground with mass = 1000 kg, and near the top of rocket we apply a force of 100 N for say 1 sec,now assume that this is sufficient to tip rocket over/start tipping over. If the rocket is mid air and accelerating at 30m/s^2, then likewise how much force would be...

    Pressurizing and Cooling liquid fuel rockets.

    Hi! I am 11, and I’m quarantined at home and bored. So, I started building an imaginary rocket! I’m not sure what thread to put this in, so if anyone wants to give me some advice on using this forum I’d be grateful. This is my question: I had an idea, of using helium (does that even absorb a...

    Arduino Radio Transceiver

    Hi, I am wanting to transmit GPS coordinates and altitude from an Arduino onboard a model rocket that will go 1km high, to another Arduino on the ground. The purpose is just to assist in finding the rocket once it lands. I was needing something cheap but also not too large (about 3-4cm). I was...

    Any Advice for HPR Build Newbies?

    Hey everyone! I decided to challenge myself and build my second 2 stage high powered rocket. It consists of mailing tubes and 3d printed parts. I ran a whole bunch of Simulations with OpenRocket and cross checked to make sure the parameters there match the actual built rocket. Yukon's first...
