I wil definitly apply your advice thanks for that. Unfortunately there will be a rocket contest in Turkey and he is one of the juries.

I have'nt finished designing the inside of rocket like(parachute,root chord), instead of this ı put some weight close to their place. For now my only worry is the stability during the flight. My other rocket whic ı am going planing to reach 9000 feet have same cp shift although it will not reach...

I have some worries about stability. There are some corruption in graphic. Is that effect my rocket trajectory?

so you are not suggesting to desing on openrocket for supersonic. Will it be work on rocksim?

Hi folks. I have some problem with the desing.My rocket will be a supersonic rocket that's why there are some diffrences with desinging. ı did a lots of simulation, althought my stabilitiy ghraphic is fine there is a warning about body calculations. ı dont know what to do. Could you help me...

Hi guys! We are desinging our rocket. Our aim is to reach 3000 m. Now we are dealing with desinginin nose cone. do you guys have any suggest or trick for nose cone desing.

got ya sorry :)

hi folks! We are building our own hpr for the contest. We must record our recovery system. We thought that if we can launch our rocket above 50 meter(less or more) we could get high points. First we should make our fuel. There are few choices for us to make . Do you guys know any fuel that we...

Labels are just the name of the components. Thanks for your comment.

Hi folks! We are going to use reloadable motor for our rocket. That's why it has to pluggable and detachtable. We are looking for some methots about motor assembly. Here is our idea. Can u guys give me some advice or another methot for motor assembly?

Yeah its huge but we will reshape it when we calculate the diameter of our parachute. We will just use it as a material. I can confirm that our rocket will be 200 lbs. Which details do u want to know?

I know it's the fifth time but ı still dont know how to calculate it. Is drag coefficient depends on the shape of chute and the metarial?

Actually we are trying to make ouw own parachute. We had huge paragliding chutes. we are trying to reshape it as a rocket chutes.

İf it's so comlex how can ı calculate my parachute diameter?

what depends on the drag coefficient number?

I know it's huge but we will sew it. 200 lps is not the exact weight of rocket, nearly.

hi guys. I have some problem about parachutes. I' dont know which coefficient should ı use for parachute. we have now paragliding parachute , we are planing to reshape it as a rocket parachute but ı coul'dt find the drag coefficient. we want to make raound parachute for our rocket. Could anyone...

Hi guys! We have chute of paragliding. we are trying to reshape the chute as a rocket chute . We have to find drag coefficient. How could ı find it ? if we must calculate, which informations we should learn about chute ?

We are making our own chutes. ı just wanted the know what size the our chutes must have. Actually we have parachute but that parachute is for paragliding. ı think it's enough to make a rocket chutes. We will sewing our chutes from paragliding parachute.
