    Flying Hoverboard
Click For Summary
SUMMARY

This discussion centers on the challenges of replicating a hoverboard similar to the one featured in Ben 10. Key considerations include selecting an appropriate thruster capable of lifting a combined weight of 80-90 kg within a 1m x 30cm x 10cm dimension and determining a suitable power supply for a flight duration of 5-10 minutes at heights of up to 100 meters. Suggestions include exploring the Space Shuttle Main Engine (RS-25) for its high power-to-weight ratio, although concerns about practicality and safety are raised regarding fuel storage and stability during flight.

PREREQUISITES
  • Understanding of thrust-to-weight ratio principles
  • Knowledge of jet propulsion systems
  • Familiarity with power supply options for small-scale aircraft
  • Basic concepts of aerodynamics and stability in flight
NEXT STEPS
  • Research the specifications and applications of the Space Shuttle Main Engine (RS-25)
  • Investigate current thruster technologies suitable for personal flight devices
  • Explore battery and fuel cell technologies for compact power supplies
  • Study the principles of stability and control in small UAVs (Unmanned Aerial Vehicles)
USEFUL FOR

Inventors, aerospace engineers, hobbyists interested in personal flight technology, and anyone exploring advanced propulsion systems.

So, some days ago I was rethinking my childhood and remember that I was obsessed with ben 10, particularly with the hoverboard in the film (https://ben10.fandom.com/wiki/Hoverboards). Right now, I really want to construct a replication of it, but I am stuck with some problems. First, what type of thruster that would fit in a 1m*30cm*10cm dimension and would be able to lift a 70 kg person and itself (maybe 10-20kg) . Second, what power supply should I use to make the hoverboard fly for maybe 5-10 minutes. I am thinking that it would fly up to 100 meter above ground. If you have a suggestion, I'm hoping you could answer me.

Your link says "Hoverboards are a type of technology, typically alien in origin" (emphasis mine). Therein lies the problem.

Well yeah. Do you have any brilliant ideas to imitate that device?
 
Based on that description, I'd start by finding an alien.

Hmm, bringing a bag of fuel every flight doesn't seem very stable and safe. Do you think if a fusion reactor exists, it could be made into a small enough size to fit in the previously mentioned dimension and have the power to fly? Maybe it will function as the combustor and pressurizer at the same time in a modified turbojet engine.

Maybe after 1000 years of refinement in design. Using near-term technology no way. A building the size of a football stadium would be closer.

Okay, but how about the Space Shuttle Main Engine (RS-25)? I heard that it has one of the highest power-to-weight ratio. Could it be used in a small device like hoverboard? What are the possible advantages and disadvantages of it?
