So I was recently reading an article about a jetpack setting the world speed record of about 35mph.
Lets face the truth, jetpacks absolutely suck as we know them today. I think we need to identify the flaws, and try to find solutions.
First off, they either use very small jets with high velocity, or use large ducted fans which make them heavy and bulky.
Secondly, their center of gravity is dominated by the pilot, forcing the jetpack to have its jets offset forward, which makes them awkward and complicates the design.
How can these two problems be overcome?
Firstly, the heavy components need to be moved as far aft as possible to help assist keeping the CG centered and not dominated by the pilot.
Secondly, the powerplant should be transverse, and mounted in a fashion which allows the torque to help lift the pilot.
The torque can be assisted by an exhaust vane as well.
Lastly, the CG automatically centers as the device flies, as leaning forward moves the pilot backward and the pack forwards. This means stabilization is only required when hovering.
As jetpacks become faster, the need for in flight stabilization will be reduced greatly due to the positive stability as the pilot leans further forward.
Anyone notice any other issues that need to be corrected, or have any solutions?
