Main Question or Discussion Point

I'm trying to make a light hovercraft powered by electric ducted fans that will have enough thrust to lift me like 10 feet off the ground. the only problem is I HAVE NO IDEA WHAT I"M DOING. can anyone help me???

i weigh 134 pounds, and the craft will weigh around 50-80. that puts the weight without the batteries and fans at 184-214 pounds. i know i need more thrust than what the object weighs to get it to float higher, but the fans will weigh a lot also, wont they? so I'm guessing i need more than 250 pounds of thrust. Anyone know how much thrust, voltage, amps, and horsepower i need to float a 214+ pound object 10 feet off the ground?

Welcome to PF, Artemis.
You're not going to get a hovercraft 10' off of the ground no matter what you do. Huge commercial vehicles with turbine engines don't lift that far. The whole point of a hovercraft is to just skim the surface.

Hovercrafts only work because they are so close to the ground.
When you get farther away you switch from a hovercraft to a helicopter -> which requires tremendously more airflow and therefore more power.

We have nowhere near enough information to answer that question - we know nothing about your hovercraft!

Very cool hybrid craft, but what gets that craft a few feet off the ground isn't the hovercraft mode, it's the ground-effect airplane mode. Danger is absolutely correct: a standard hovercraft is limited to mere inches of altitude, inherrent in the design.

Btw, moving this to the aerospace forum.

mythbusters made hovercrafts from everyday objects, maybe watch that episode
