BTIR Project Concept and Developments

Proposal for a very simple unguided rocket without parachute, for fun and science

Introduction & Concept

After a bout of boredom powered inspiration, I have conceived of a ‘stopgap’ rocket to tide me over until proper launches can be conducted
Introducing: the BTIR, or Ballistic Trajectory and Impact Rocket

Rocket Altitude Estimator

A simple program to estimate flight performance, from nakka’s calculations

The Program

Rocket Estimation, Altitude CalculatoR, or REACT, is a small program I wrote to give a quick and rough estimation of a rocket’s flight performance

The formulas are blatantly stolen from Richards nakka’s .PDF on the subject

First, the … Read More

STS-XL

The 20 times as strong Static Test Stand eXtra Large specifically designed to test MM-38

Overview

After being gifted such a beast of a engine it was quickly deduced that a different Static Test Stand had to be devised and built for proper testing

It took allot of time, resources and outside help, but its … Read More

R-10 Test Results

The 10’th rocket test after rocket 0, the 5th casing 2.0 iteration, also being the first to not suffer from miscellaneous structural failure

Hopefully, the 27th time’s the charm!

Grant Imahara, Mythbusters

I made the casing 20 design in begin December 2020, and made a total of 4 (R-6 to R-9) in the following 3 months.

R-6 had a structural failure at the … Read More

Gifted Engine: MM-H-38

A article all about the recently received MM-38 rocket motor, featuring dimensions, a banana, and a design or 2 of my own

I recently got into contact with a veteran experimental rocketeer, who generously provided his help with my rocketry program

He generously provided help designing my own engine (more on that later), lent us a Emco Unimat 3 lathe to build … Read More

Impulse Calculator 2000

A program I wrote to calculate impulse from STTS readings (with download and detailed explanations of the math behind it)

Ever since I made my STTS system and started testing my rockets on it I have wanted a way to calculate impulse from it, specifically in newton seconds

I quickly found nakka’s article on the subject, and after alot of … Read More

Prototype Parachute Development (1/2)

Development and testing of exploratory parachute systems, also known as me chucking stuff from a balcony

What goes up must come down

Gravity

Making something go down is quite easy, you just let it go from some height and it will swiftly hit the ground
Making something go down slowly however is quite a challenge
To … Read More
