What kind of engine do I need to build a flying board ?

Click For Summary

Discussion Overview

The discussion revolves around the feasibility and design considerations for building a "flying board" using various types of engines and propulsion systems. Participants explore different methods of achieving lift and thrust, including jet engines, propellers, and other propulsion technologies, while addressing stability and control issues.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests using multiple engines, including small engines for lift and thrust, and expresses uncertainty about the required power for lifting a combined weight of 160 lb.
  • Another participant recommends the 'JET CAT P200' for thrust and proposes using propellers for hovering, though they have not determined which propellers would be suitable.
  • A different participant highlights stability as a major concern for hovering, suggesting a "quad copter" configuration for the engines and mentioning the need for significant thrust, possibly from pressurized gas.
  • One participant proposes that ducted fans powered by electric motors or two-stroke engines would be the most efficient propulsion method, while expressing a preference for working on a VTOL 'JET BIKE' instead of a board.
  • Several participants discuss the distinction between hovering and flying, questioning the utility of a platform that only hovers without forward motion.
  • Another participant mentions historical attempts at flying platforms, specifically a US Army project from the 1950s, and suggests that air cushion pads could be a practical solution for a DIY hover platform.

Areas of Agreement / Disagreement

Participants express a range of views on the best approach to building a flying board, with no consensus on the optimal engine type or design. There is ongoing debate about the importance of hovering versus flying and the challenges associated with stability and control.

Contextual Notes

Participants note various limitations, including the complexity of gas turbines, the need for sufficient thrust, and the potential operational challenges in windy conditions. The discussion reflects a variety of assumptions about propulsion technologies and design feasibility.

What kind of engine do I need to build a "flying board"?

Hi there,

I'm pretty much new here and I've been making lots of research about engines, ion engines, turbines etc. But I still don't understand.

I want to build a steel board, since I have the facility to work with any kind of metal because of my dad. The thing is I want to make the board "fly", just enough to keep it away from the floor. I want to have that feeling of being on a "flying board" working with engines. Those kind of engines that use flame throwers or wind or whatever, I see that aircrafts does not throw flames though.

I'm pretty much new to engines and that stuff but I'm not stupid, and I learn right away everything I read.

I will need more than 1 engine, maybe 2 engines under the board to lift it and keep it "floating" at any height and another engine to make it move forward, to cause thrust. I want to control this board with any device on my hand, that'll be another topic. For now I want to build the engines, propulsory system, turbine, ion thrust or whatever is called :)

Of course I don't want a big engine, I want them small, the board will be very big, maybe as long as a snowboard or a bit more, but way wider, maybe twice a snowboard. I don't know how much power the engines will need to lift me (including the board) I weigh 160 lb though.

Is this possible?

Thanks a lot! I'm really into this, I have the facilities to everything at my dad's office, thanks!:smile:

Hey, I'm also researching on the same thing that you are on . Through my research I would prefer you to use ' JET CAT P200 ' for thrust which would give it accelaration but still i think you should use propellers under the board to keep the board hovering . I have not yet figured out which propellers should do .™

If you want to make a hovering board your biggest issue will probably be stability (assuming you can find an engine that produces a sufficient amount of thrust). Your best bet may be to configure your engines in the "quad copter" style. If you are planning to make it so you can lift your body in the air, good luck. You will need quite a bit of thrust, perhaps pressurized gas to get it to hold you in the air for an appreciable amount of time.

Something else you may be interested are the "Ekranoplans" built by the Russians. These are also known as ground effect vehicles.
 


I have thought about the same thing. At that size, ducted fans powered by electric motors or two stroke reciprocating engine will be the most efficient method of propulsion. Gas turbines will be much too complicated and the fuel consumption will be too high.
After giving it a lot of thought, I gave up the idea and decided to work on a VTOL 'JET BIKE' thing. It's a long term project. It's stability will be greater than a board since you don't have to stand on it. Think about it.
 


That depends. Do you want to hover or fly?
 


It will not mean much if it hovers motionlessly, will it?
 


That depends completely on your goals. Using sound pressure to hover the weight of a human would be extremely impressive and unheard of.

The US Army built and flew a flying platform in the 1950s, based on a ducted prop in the base of the platform.
The vehicle was controlled by leaning in the preferred direction. The platform was about 5 feet wide and four feet high, mostly railing for the pilot/user to hold on to.
The vehicle was demonstrated to about 20 feet height, so it could cross obstacles.
Nothing came of it, so presumably there were problems with operations on windy days or with several together.
For a 'do it yourself' hover platform, I think one of the air cushion pads would work, as they float using compressed air squirted out the bottom of the platform.
As long as there is a flat floor, the platform can float with little power about a tenth of an inch above the floor. Works great for moving aircraft assemblies.
