How many fins must be attached to the water bottle rocket to give it the longest airborne time?
3 t05 fins
How many fin's should a rocket have?
It depends on a lot of stuffs like how much do you want your rocket to be stabile. But at least it must be 3. For example for the same stability you may have 3 fins that have large surface area or 4 which is smaller or more. When you increase the number of fins with the same surface area then the drag will increase because of the surface friction so 3 or 4 fins are generally used but there is no certain limit of the number of fins .
How many fins does a rocket need to travel straight?
Three fins are needed on most model rockets. More is ok if aligned properly, but less will cause instability in flight.
How many fins must be attached to the water bottle to give it longest airborne time?
4 to 3 fins
How many forces acting are on a water rocket?
There are two forces acting on a water rocket. The thrust which the force that is given to the water rocket to make it move, and the other one is the gravity.
What is the best material to use for fins on a bottled rocket?
Yes or else the rocket won't be stable and will veer off course. Three or four fins is the best number of fins, more and you are just adding drag, less and there is not enough stability
What do you call the wings of the rocket?
Rockets do not have wings.However rockets need a means of stabilization and control, this can be done two ways:thruster controlsfins (this will only work while the rocket is in the atmosphere)With thruster controls the rocket engine thrust may be varied, the rocket engine nozzles may gimbal, or auxiliary thrusters may be used.What you are probably thinking of is the fins, which can be either fixed or movable. But they have no lift and are not wings and as stated above many rockets totally lack any fins.
How many fins should you put on a long range bottle rocket?
easy! get some balsa wood and a modeling knife!and cut out a simple shape!balsa wood is ok because it is light in weight, however, if your rocket has a crash landing the fins will not likely survive. I suggest something a bit more sturdy. on some rockets i have used chucks of CDs as fin material (they're harder to snap than you would think) i would also suggest arrow glue ( like the glue for archery arrows) as an adhesive for fins shape? i would check out this web site. the fin designs are not difficult to create and the shape is backed up by the Reynolds number don't know if you know any thing about that http://www.apogeerockets.com/technical_publication_16.asp.best of luck! :]
