    JrHPR Recovery Setup

    So I’m 17, and I am attempting my L1 soon, I have a fairly large 4” x 6’ rocket that I have designed and built, and the only area I am unsure in, is recovery setup. It’s just a single deployment system via the motor (obviously since it’s my jrHPR cert) and I’m not sure which principles carry on...

    GPS DriftCast (GPS Drift 2.0) Vastly improved landing location prediction based on winds aloft forecasts

    Alright, If any of you have followed or seen GPS Drift, an excel spreadsheet that helps you predict the landing location of your model and high power rockets. I wrote it back in 2021. @MarsLander recently reached out about a weathercock addition to the sheet. This was added and released -...

    I want to adapt the ejection charge, whose material I don't know, to FFFFG black powder

    Greetings to everyone. This year, I will be participating in the High Power Rocketry competition called TEKNOFEST Rocket Competition, which is held in my country. In this competition, a ejection charge is used in which the material and weight data are not given. The only thing I know about this...

    Gore DXF generator file. (Automatic parachute designer)

    When designing parachutes on your own, the process can be quite challenging. That's why I've developed a manual along with a program that generates DXF files for the gores intended for laser cutting. Currently, it's tailored for hemispherical parachute designs featuring a small spill hole. I...

    Unable to obtain minitimer for our payload's recovery system. Any suggestions or replacements we should look into?

    Hello, My team and I have been working on a payload project where our recovery system needs to be delayed but a couple of seconds after it has separated from the rocket. We have been attempting to get our hands on a minitimer since the end of last year, and still have yet to find one for sale...

    Rear deployed chute

    How would I go about a rear deployed parachute? Not any particular build or rocket just in general. Would it involve redirecting the ejection charge blast with an mushroom or inverted funnel type shape?

Will epoxying the top CR/recovery eyelet to the fin can by applying an epoxy to the inside and outside of the MMT(inside radius), then epoxying CR to the inside of the coupler going to...

    ARRD working mechanism

    Hi, I hope everyone is well. We want to use ARRD in our rocket. But there is a point we don't understand in a working mechanism. Before we buy it, we need to understand the system. The key point is the connection. How it is connected to the body. What is the function of ball bearing? Is it just...

    Rocket Paraglider - Flying A Traditional High Power Rocket Back to You!

    So I may be new to this forum but I am not new to rocketry. With that in mind I cam up for this concept of what I like to call "active recovery" where the parachute is controlled in some way. The idea here is that after being inspired by an Radio controlled paraglider I saw, why not incorporate...

    Line Cutter…

    I have a Prairie Twister that doesn’t seem to “cut it” (sorry for that) but seriously I can’t get it to cut a zip tie even when I pack it full of 4F powder. I’ve thought of milling one end to something of an edge as both sides are blunt. Any thoughts or suggestions? Thanks in advance. Philip

    Question on parachute fabric

    I am sewing my own parachute using Scotty Bryce's template. I wasn't able to find 1.1 oz ripstop nylon which seems to be the go-to fabric. The only ripstop I was able to find locally (Calgary, Alberta) was much heavier. I think over 6 oz. Aside from adding weight to my rocket, do you foresee...

    GPS Drift, Rocket Landing Predictor and visualizer Spreadsheet

    Out of a desire to understand a little more where my rockets could potentially land leading up to the launch, and the morning of launch. As well as predicting where anomalous flights may go(main at apogee failures anyone?) Especially after having treed a couple rockets in my close flying circle...

I will be building a LOC Warlock 54mm with a 6 ft main chute and I want to have some way of a low main...

    Thoughts on drone recovery?

    I’m sure people have tried this by now... what are y’all’s thoughts on drone recovery of rockets? I see this being helpful for reconnaissance of a property you don’t have permission to be on.. looking around for the rocket. Then maybe even actual recovery by installing a hook and landing on top...
