- This week we take a look at the start of construction of our Level 2 HPR cert rocket called "Tajfun 2" (pronounced Typhoon 2). We look at making the payload bay tube, the nosecone, motor tube and the removable nozzle.
it is magnificent that you use simple tools like a pizza cutter for the fiberglass. We really need to think a bit simpler. That tipp will be used ❤. Well then the production of the nozzle is shown an we instantly feel like we are just some guys without any proper equipment. Loved the video though . great process so far
Thanks, although it looks like a pizza cutter, it is actually a roller cutter typically used for cloth. (here is an example: www.scissorman.com.au/product-tag/rotary-cutter/) If you ever need to cut fiberglass cloth, it is the ONLY tool to use. You'll never go back to scissors once you've used it. Much cleaner and faster for complex or straight cuts.
yes looks like it we used a big commercial cutting Maschine but the blade was getting absolutely destroyed by the cloth. We will definitely invest in such a tool. thank you 😊
If you wanted to do something 'rocket' like, you could use gas to pressurize the rocket to keep it rigid
Enjoyed the video(s).
You probably know it, but filing or sawing fiberglass will quickly dull your tools. Glass is much harder than steel, so it is not ideal to cut it with with steel tools. With the hacksaw, it's probably fine as the blades are cheap anyways, but I wouldn't use a file for it.
Yup definitely good advice. We do go through quite a few blades, the better quality ones last a little longer. Surprisingly the cheap file we use on the fiberglass has lasted a couple of years and still does a reasonable job. We don't use our good files on the fiberglass.
Nice video ! Have you ever tried the FG sleeve to make the nose cone ? It's a _whole_ lot eaiser, faster, cleaner, it's also seemless, and you already buy sleeve from soller so...why not ?
Never tried it on the nosecone. I've thought about it though, the problem I see is that you still end up with a transition somewhere along the nosecone. The sleeve will only shrink down so much without folds, it won't go over the tip and you end up with frayed edges where you cut it. You could maybe use two sizes but because of the taper you can't pull the second one tight. Have you used them yourself? I'd be interested in knowing how you do it. Going from 4.5" to a tip?
Its always such a good moment in my day to watch a new video from your channel. I have a question for you. Sorry if you already responded and I missed it but do you have a strategy for fiberglass sheets overlaps? Any fixed amount? (ex. 2 cm or 1/6 circum.) Thx. Greetings from Canada.
Hi, and thanks for your support. :) Yup, exactly, the last circumference wrap overlaps by 2cm. If we then do a second wrap with another sheet, we always end it on the opposite side of the mandrel so that the two overlaps are opposite each other to try to even out the forces on the pressure chamber.
What a great work!! I am so impressed! What type of aluminium you used for the nozzle and the internal diameter for the nozzle? sorry if it is already on the video ;)
Thanks. I am not sure what the aluminium was, but it was easy to machine. Nozzle diameter is 15.6mm.
@@AirCommandRockets Thank you for the answer! I am building a water rocket in Korea for the first time. I wanted to build a L2 HPR but launching and making a solid rocket fuel are illegal here, so I turned into water rocket and it fascinated me. Your video helped a lot Thanks again. Keep up the good work!
Excelente labor!!!
Es de destacar vuestra prolijidad en la construcción del cohete. Espero la siguiente parte y ansioso de verlo volar. Saludos desde Uruguay 🇺🇾
Thank you thorinti :)
do you experience constant crashing of 123d Design? How do you fix it? Much appreciated.
what material is this that covered the whole thing?
The whole rocket is made out of fiberglass. We use West Systems epoxy resin.
Great video!
When is the launch of Tajfun 2?
We are aiming for August for the cert flight on a J360. The water rocket launch happened last month: ruclips.net/video/aCafRBu3yGE/видео.html
