What is a High Power Rocket?

  • Not to be confused with a model rocket
  • Significantly larger, more powerful, more

dangerous

  • Need FAA waivers to fly
  • Uses ammonium perchlorate composite

propellant (APCP) or experimental propellants

– Typically not black powder

Rules and Regulations

  • NFPA 1127
  • High Power Rocket Safety Code

– Certification – Materials – Motors – Ignition system – Misfires – Launcher – Size – Flight safety – Launch site – Recovery system

How do I get certified?

National Association of Rocketry (NAR)

  • Level 1

– Build and successfully fly a conventional rocket with a single H or I commercial motor.

  • Level 2

– Build and successfully fly a conventional rocket with a single J, K or L commercial motor and pass a written exam (88% or better).

  • Level 3

– Build and successfully fly a conventional rocket with a single M, N, or O commercial motor and have the design verified by the L3CC.

Tripoli Rocketry Association (TRA)

  • Level 1

– Build and successfully fly a conventional rocket with a single H or I commercial motor.

  • Level 2

– Build and successfully fly a conventional rocket with a single J, K or L commercial motor and pass a written exam.

  • Level 3

– Build and successfully fly a conventional rocket with a single M, N, or O commercial motor and have the design verified by 2 TAP members and have successfully completed a flight using electronic deployment mechanisms.

Level 3 High Power Rockets

  • Impulse range

5,120-40,960 N-s

  • Includes M, N, O

commercial motors and larger experimental motors

  • Typically involve

electronics for deployment and much heftier construction.

Class 3 Rockets

  • A rocket with total

impulse exceeding 40,960 N s

  • Equivalent to a P

motor and greater

  • Requires a special

FAA approval in addition to FAA waiver

Engineering Considerations

  • Stronger materials

– Fiberglass, carbon fiber, thick plywood

  • Electric systems

– Parachute deployment, data sensing and acquisition, tracking, beaconing, lights

  • Aerodynamics

– Stability, fin flutter, Mach number

  • Thermal

– High velocities, recovery pyros, electric systems
