How big should my rocket fins be?
The design formula further provides that width of each fin should be at least 1.25 times the diameter of the rocket body. The cut and try method of fin design is probably the most widely used and the most successful.
Can a rocket be too stable?
Being over-stable is not bad. It basically means that the rocket will have a greater tendency to weathercock if there is any wind at launch. In- stead of the rocket going straight up, it will gradually turn into the wind. It is possible that the rocket could travel horizon- tally — which is bad.
Are longer rockets more stable?
The larger the number, the more stable the rocket is.
Why are rockets tall and skinny?
Why are rockets tall and slender? – Quora. basically, it’s a question of drag. The less area you expose normal (perpendicular) to the free stream, the less drag you have.
Why are longer rockets more stable?
The bigger your fins, the farther back the CP. You can more easily move your Center of Gravity by adding weight to the nose of your rocket, or making your rocket longer. This moves the CG towards the front. This is called one-calibre stability, and most rockets are close to this.
How high can a homemade rocket go?
By the early 1960s, more than 5,000 amateur rocket clubs with more than 40,000 active members operated in the United States. As the rocket builders became more sophisticated, some built rockets that weighed up to 75 pounds and could reach an altitude of over five miles.
Do you need permission to launch a rocket?
The first requirement for any launch site is permission of the owner to use it for flying rockets! Use of land–even public property–without permission is usually illegal and always a bad example for a NAR member to demonstrate responsible citizenship.
Can sugar be used as rocket fuel?
Fuels. Many different sugars can be used as the fuel for rocket candy, including glucose, fructose, and sucrose; however, sucrose is the most common. Sorbitol, a sugar alcohol commonly used as a sweetener in food, produces a less brittle propellant with a slower burn rate.
How much does rocket fuel cost?
kilogram of the fuel. While finding the liquid propellant costs is relatively easy, finding costs for solid fuels is more difficult. However, the cost of solid rocket propellant is estimated at approximately $5/kg.
