Off-world Power Generation Lab 3: Propulsive navigation

This lab is focused on 3d-printing a single component. We want to put a check valve and a release button in series. Gonna require some 3d modelling!

Concepts:

• Research
  • Thrust vectoring for attitude control
• one-way valve with return flow release toggle
  • i just need a check value in series with a release valve
  • needs to be inflatable via bike pump (initially) or air compressor (once we have many to inflate at once perhaps)
  • needs an easy-to-press release toggle that a weak cheap actuator can press
  • tesla valve? no
• OPTIONS
  • Ideally, it would have a large chamber - but there is a power vs weight relationship that we need to optimize for our application.
  • At some point, it will become a requirement to know the internal pressure - do we attempt to add a sensor now, or later?
  • See 1:06 of NASA and SpaceX: Journey to the Future for details of Dragon capsule Draco thrusters

Required:

• ✓ 3D printer + filament
• ✓ Silicone for check valve stopper
• Initial models (to be merged)
  • check valve
  • pipe with release valve
  • male bike pump coupler
• 3D modelling tool

Step 1: Get initial models

Check valve

Step 2: Merge models into final design

Use either blender or Fusion 360, probably fusion
