parachute

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...

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 -...

Hello everyone, hope everyone's doing good! So today finally came the day to start thinking and designing the parachute for my rocket. First of all some details, It is a 140cm high rocket roughly weighing 2kg, We are expecting it to reach an apogee of 800m and a velocity of 0.5 mach. So here are...

I need help understanding how to pack recovery wadding. After my first couple launches, the parachute was always a little burnt, until there was a hole in it from all the heat. After doing some research, I figured out that recovery wadding is supposed to completely block the air, and an easy way...

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...

I seek advice on the viability of a modification to the recovery of an Estes 1/100th scale Saturn V. Rather than having the Saturn V upper stage and booster return separately, I want them connected by a common shock cord. They both retain their own parachutes. The upper stage would act like a...

I would like to hear some different rocketeers methods of folding chutes. I always use the Carlisle method, which Is pictured in the handbook of model rocketry, but I would like to see other's methods. Maybe some specific "best for" methods. (Best for opening quickly, slowly, best for...

How can i determine packing size of a parachute in real life from open rocket? i got packing diameter - 3.8inch and packing length - 15.7inch in Open Rocket for the 12ft Pro Experimental Drogue Parachute by Rocketman. This will be used in a rocket whose apogee is around 3000 feet (1 km to be...

Hello, I have a streamer I'm using as a drogue, with a LOC parachute (jolly Logic @ 800'). What order on the shock cord should I put them on? Booster -> Streamer -> Parachute -> Nosecone? Booster -> Parachute -> Streamer -> Nosecone? Thanks!

Hi all, Looking for a large parachute something in the 15+ ft range for a large upscale project I’m working on for Red glare and LDRS this year! Looking for something used to help out on the budget! No preference on manufacturer or color scheme, let me know what you’ve got and I’ll see if we...

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?

Hi, there I am using a parachute(parafoil) to steer the payload. I need the code for that, by steering I want to reduce the range. Can anyone help me in this.

Hello fellow rocketeers, hope you are doing great. I was thinking about fitting my Eggtimer Apogee in the nose cone but then I realized the ejection charge should be oriented downwards, right? Then it would fire and push the parachute and the rest of the body downwards, and depending on how...

I am a member of a newly founded rocketry team in my University. We are very excited to build our first rocket, however, we have no prior knowledge. Upon investigating different methods for Dual Deployment Systems, Theo W. Knacke in his book "Parachute Recovery System Design Manual" mentions a...

Hello everyone, I’m looking to sell these brand new parachutes, mostly because they were used for website photos or made special colors for someone and have an extra. These are in perfect condition, all prices will be with shipping included and 20% off!!! All of these are absolutely beautiful...

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...

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...

Like many others, I found a great deal on the Estes Goblin at Hobby Lobby yesterday--$4.39. At the time of purchase, I did not know it uses the streamer recovery system. Never used streamers before. If I convert to a parachute instead, what size should I use? Anything about the shock cord or...
