HPR2254: Introduction to Model Rocketry

Introduction to Model Rocketry

In this episode I introduce the hobby of model rocketry. I specifically highlight some of the advanced elements of the hobby to show how model rocketry goes from being a fun activity for kids to a serious hobby enjoyed by many adults.

Outline

1. History of model rocketry.

• Early amateur experimentation with rocketry.
• G. Harry Stine develops the model rocket motor.
• Vern Estes develops a way to mass produce motors.

2. Basic model rocket components and flight.

• Airframe, nose cone, and fins.
• The part of the model rocket motor.
• Recovery mechanism (parachutes and streamers).
• The launch pad
• The basic flight profile of a model rocket.
• Building a typical model rocket kit.

3. Scratch building your own designs.

• Using commercial components.
• Using ordinary materials for rockets.
• Fabricating components: Lathes, laser cutters, CNC machines, etc.
• Using CAD and simulation software.

4. Craftsmanship and scale modeling.

5. Model rocket competition.

• Regional, national, and international meets.
• Events: Altitude, duration, advanced recovery methods, payloads, egglofting.

6. High power rockets.

• Large rockets.
• High altitude rockets.
• Supersonic rockets
• Composite motors.
• Regulations
• Certification
• Materials

7. Complex rocketry.

• Motor clustering.
• Staging.
• Dual deployment.

8. Electronics

• Altimeters
• Flight computers
• Tracking
• Cameras

9. Experimental motors.

10. National associations.

• National Association of Rocketry (NAR).
• Tripoli Rocketry Association (TRA).
• Safety codes.
• Liability insurance.
• Local clubs.

11. Safety.

12. A little about my personal interests in model rocketry.

Errata

In the show I said that G. Harry Stine worked at the White Sands Missile Base. The correct name for that facility is White Sands Missile Range. But, during the time that Stine worked there, it would have been called the White Sands Proving Ground. https://www.wsmr.army.mil/
