Rocket Geometry Sep 22

Amateur Rockets

  • Needs parachute
  • Most amateur rockets will have some form of recovery
  • Nosecone
  • Body
  • fins
  • motor
  • parachute
  • the rest is all yours to do something with!

Flight Path

  • Launch
  • Ascent
  • Motor Burnout
  • Apogee
  • Seperation
  • Parachute Deployment
  • Slow Descent
  • Recovery

How do you manage all of the space??

Rocket

  • One parachute, one method of detecting apogee
    • Motor Delay
    • Altimeters + Flight Computer
      • Some way of detecting apogee
  • Dual Side dual deployment.
    • separation -> drogue deployment (Slow slightly to prevent drift) -> main deployment (slow to safe recovery speed)
    • altimeter goes between parachutes typically
    • add a tiny tube that permanently bonds to the rocket, to permanently rest on the tube, so that the shear pins dont take the force of the drogue parachute.

High Speed Rocket (Single Side Dual Deploy)

  • Super big motor, and then basically the nosecone.
  • where do we put the two parachutes?
  • same as single sided, the altimeter is either at the top or the bottom
  • bulkhead between altimeter and two parachutes.

Drogueless

  • The rocket separating in half creates enough drag to slow the rocket
  • never do that, many tried, many failed.
