Nose ConeNose Cone The nose cone has a The nose cone has a

very pointy tipvery pointy tip The reason for this The reason for this

pointed shape is to pointed shape is to reduce the amount reduce the amount of wind resistanceof wind resistance

The pointed shape The pointed shape also allows for also allows for increased increased aerodynamicsaerodynamics

Wind resistanceWind resistance&&

Aerodynamics Aerodynamics

Wind Resistance is the Wind Resistance is the resistance too movement caused resistance too movement caused by an object moving through the by an object moving through the airair

Aerodynamics is the term used Aerodynamics is the term used to describe when something is to describe when something is built to allow for even air flow built to allow for even air flow and reduced wind resistanceand reduced wind resistance

Body TubeBody Tube The body tube is The body tube is

the main housing the main housing for all the rockets for all the rockets parts and systemsparts and systems

Model Rocket FinsModel Rocket Fins The fins are The fins are

attached to one attached to one end of the body end of the body tube with gluetube with glue

the fins help to the fins help to give the rocket give the rocket stability in flightstability in flight

The Alpha kit has The Alpha kit has three finsthree fins

StabilityStability

The ability for the rocket to fly in a The ability for the rocket to fly in a straight upward path when it leaves straight upward path when it leaves the launch padthe launch pad

Stability is one of the most important Stability is one of the most important aspects to ensure a safe flightaspects to ensure a safe flight

Model Rocket Launch LugModel Rocket Launch Lug

The launch lug The launch lug will be glued at will be glued at the location on the location on the tube marking the tube marking guideguide

Launch PadLaunch Pad The launch lug of the The launch lug of the

rocket is slipped rocket is slipped onto the launch poleonto the launch pole

Make sure the rocket Make sure the rocket slides easily all the slides easily all the way down to the way down to the metal platemetal plate

If rocket slides hard If rocket slides hard on pole check launch on pole check launch lug for obstructionslug for obstructions
