SUMMARY

Triangular toothpick ion engines, also known as ion lifters, are capable of achieving lift on Earth due to their unique design and operation principles. Unlike traditional ion engines used in space, which rely on a vacuum, these lifters utilize ion propulsion to generate thrust in the atmosphere. Key factors influencing their performance include thrust-to-weight ratio and the type of ions used, particularly when considering their effectiveness at varying altitudes. Power supply considerations are crucial, as lifters that draw power from external sources do not contribute to their own lift.

PREREQUISITES
  • Understanding of ion propulsion principles
  • Knowledge of thrust-to-weight ratio calculations
  • Familiarity with specific impulse (Isp) in propulsion systems
  • Basic concepts of atmospheric density and its impact on lift
NEXT STEPS
  • Research the design and functionality of ion lifters
  • Explore the physics behind thrust-to-weight ratio in propulsion systems
  • Learn about the differences between ion engines in atmospheric and vacuum conditions
  • Investigate the implications of power supply methods on lift capabilities
USEFUL FOR

Aerospace engineers, physics students, hobbyists interested in propulsion technology, and anyone exploring innovative lift mechanisms.

These are machines that I just learned about while I was bored. So, i will now ask about what looks like a triangular toothpick ion engine.

So these lifters are really strange, I don't know how they work,

here they are.

From what I have read though, they are ion-like engines, which are capable of on-ground rising, something ion-engines in space can't do.

Well, one has to look at thrust to weight ratio. If thrust is less than weight, there is not acceleration. Also, consider what ions are being used. If the ion lifters use air, then they would be useless in space, which is essentially a vacuum, i.e. very low particle density. And lifter capability would diminish with altitude.

If lifters receive power from wires, then they are not 'lifting' the power supply, which would add weight.

See this article for more information -

Ion thrusters do work in space - in 'low' gravity fields. They have relatively high Isp (specific impulse), but low thrust.
