2. Parts of a Model Rocket Nose cone Body tube Fins Launch lug

3. Nose Cone The nose cone has a very pointy tip
The reason for this pointed shape is to reduce the amount of wind resistance
The pointed shape also allows for increased aerodynamics

4. Wind resistance & Aerodynamics
Wind Resistance is the resistance too movement caused by an object moving through the air
Aerodynamics is the term used to describe when something is built to allow for even air flow and reduced wind resistance

5. Body Tube
The body tube is the main housing for all the rockets parts and systems

6. Model Rocket Fins
The fins are attached to one end of the body tube with glue
the fins help to give the rocket stability in flight
The Alpha kit has three fins

7. Stability
The ability for the rocket to fly in a straight upward path when it leaves the launch pad
Stability is one of the most important aspects to ensure a safe flight

8. Model Rocket Launch Lug
The launch lug will be glued at the location on the tube marking guide

9. Launch Pad
The launch lug of the rocket is slipped onto the launch pole
Make sure the rocket slides easily all the way down to the metal plate
If rocket slides hard on pole check launch lug for obstructions
Launch pole
Metal plate

10. Systems of Model Rocketry
Propulsion system
Ignition system
Recovery system

11. Propulsion System Model rockets use solid fuel engines for propulsion
The area colored red is for lift off
The blue area is tracking smoke to help measure altitude
Yellow area ejects the parachute

12. Parts of the Propulsion System
Engine mount tube is light blue
Adapter ring is green
Engine hook

13. Construction of the Propulsion System
Cut a small slit at one end of the engine mount tube

14. Construction of the Propulsion System
Insert engine hook into slit in the engine mount tube

15. Construction of the Propulsion System

16. Recovery System
The recovery system consists of the parachute and the shock cord
The recovery system allows the rocket to fall at a slower speed and a smooth even pace
Shock cord

17. Nose Cone
This section of the nose cone needs to be cut out to install the parachute and shock cord of the recovery system

18. Installation of the Recovery System1 2 3
1. Cut nose cone section
2.Bundle the three parachute cords
3. Feed the shock cord and parachute
strings through nose cone and tie
into a knot

19. Ignition System
Electrical launch system
Igniter
Retainer plug

20. Ignition System Igniter
Electrical connectors are added to both ends of the igniter
Electrical current flows to the pyrotechnic (flammable) material to light the solid fuel engine
Electrical connectors

21. Igniter installation Insert igniter into small hole of rocket engine
Place yellow retainer plug into hole with the igniter
Push down retainer plug until snug and bend igniter slightly as shown

22. Final Launch Sequence This devise can be used to
measure the altitude of the rocket
