	Multistage rocket - Wikipedia, the free encyclopedia
		The first stage is at the bottom and is usually the largest, the second stage above it and is usually the next largest, etc. In the typical case (linear staging), when the first stage's motor(s) fire, the entire rocket is propelled upwards.
		When the first stage's motor(s) run out of fuel, the first stage is detached from the rest of the rocket (usually with some kind of small explosive charge) and falls away.
		Since staging is expensive in terms of manpower, a new movement has concentrated on single stage to orbit designs that do not have separate stages.

	Norfolk and Suffolk Rocketry Association
		Staging is a technique used by rocketeers to gain higher altitudes, by utilising two or more engines that fire in series, one after another.
		Although this means that the first stage of a rocket will lift it far less than if equivilant motors were used on their own, the final stage will only have to lift the remaining weight of the rocket plus itself, and begins firing already at altitude and speed.
		The addition of the crude second stages moved the point of engine thrust too far away from the fins, and pushed the centre of mass prortionally further away from the rear of the total new rocket length.

	Rocketry Frequently Asked Questions
		Model rocketry is a very safe hobby as long as you fly by the NAR (or CAR if you live in Canada) safety code.
		Series staged rockets contain motors that are stacked one on top of the other inside the rocket which are usually successively smaller the farther up the rocket they are.
		The motors in the first stage are ignited at the launch pad and once the fuel burns out, that section of the rocket falls away to reveal another motor for what's left of the rocket which then ignites and then continues upwards.

		The group is then responsible for organising and managing the gathering of the required materials and tools (in consultation with the class’ Design and Technology teacher) and building the "Bottle rocket and Launcher" in the given time allowed by the teacher.
		Rocketry is an area where much research has been carried out and a base of knowledge has been built up.
		Keeping safety as the number one consideration, the next step in your development of Rocketry understanding is to work in groups of 4 or 5 under the careful guidance of your Design and Technology teacher to build a model rocket that is of a tested and proven design.

		Assume a two stage rocket where the booster motor burns for 2.5 seconds, and its thrust curve shows a significant decrease in thrust after 2 seconds.
		If staging is performed after booster motor burnout (after 2.5 seconds), the rocket may coast for about 1 second before the sustainer's motor ignite.

		Two popular uses of "active" electronic payloads are the staging timer and the ejection timer; they typically use low-cost timer chips but some are based on more accurate crystal clock designs.

		There were various stages of faffing with the design, and several false alarms when SpaceCAD threw up some very odd numbers (I'm using an old and buggy demo version of SpaceCAD3), but in the end I came up with something looking quite military, and most definitely the biggest, most powerful rocket I'd ever built.
		I did this on both stages, and ended up with fins that feel a lot stronger than balsa fins of equivalent size, and which are also much tougher, being less flexible and less easily damaged.
		For example the booster stage could be attached to the upper chute bay and flown as a 6-D cluster, or the interstage could be switched with the upper electronics bay, or the sustainer could simply be flown with a weighted nosecone.
