primary project objectives
Primary Project Objectives
  • Build hybrid rocket motor
    • paraffin wax fuel
    • nitrous oxide oxidizer
  • Conduct static test fire
  • Complete fabrication of rocket
  • Launch rocket to an altitude of ~12,000 ft.
  • Collect various in-flight data- acceleration curve- flight trajectory- altitude at apogee- onboard flight video
paraffin and nitrous oxide test hybrid rocket
Paraffin And Nitrous Oxide Test Hybrid Rocket

Advantages of Hybrid Rockets

  • Mechanically simple compared to Liquid Rockets
  • Safer and more controllable than Solid Rockets

Advantages of Paraffin

  • High Regression Rate
  • Practical Single-Port Design
  • High Energy Density (~same as kerosene)
  • Inexpensive
  • Non-toxic

Advantages of Nitrous Oxide

  • Available
  • Inexpensive
  • High Density
  • Self-Pressurizing
oxidizer fill and ignition system
Oxidizer Fill and Ignition System
  • Fill internal oxidizer tank via external, commercial nitrous-oxide tank.
  • Light solid propellant ignition charge via electric match.

recovery system
Recovery System
  • Drogue opens at Apogee
  • Main chute deploys at 1500 ft
  • Landing at less then 21 ft/s
payload layout
Payload Layout
  • Fiberglass construction
  • Cowlings produce less drag than increasing the entire body diameter
  • Camera has downward view during entire launch
slide9

PayloadLayout

  • Polystyrene foam insert protects electronics
  • 3 axis accelerometer mount
construction
Construction
  • The graphite nozzle is turned on the lathe
construction11
Construction
  • Niroshen taps the vent hole
hydrostatic test
Hydrostatic Test
  • Oxidizer tank successfully held 1500 psi
hydrostatic test13
Hydrostatic Test
  • Hydraulic pump is used to pressurize tank
fuel grain
Fuel Grain
  • Paraffin grain fits neatly into combustion chamber
upcoming events
Upcoming Events
  • Completion of procurement phase
  • Hydrostatic test of fill system
  • Static Test Fire
  • Final Construction Phase
