AERODYNAMICS OF HOVERCRAFT PDF

Key concepts. Vehicles Air Friction Engineering Aerodynamics Introduction Have you ever ridden on a hovercraft? It is like gliding on a cushion. Our goal is to make our hovercraft design more aerodynamic by reducing the cross-sectional area of the reference face and eliminating any flat surfaces. I can’t speak to what sources you were reading, but the air under a hovercraft is higher than ambient air pressure, not lower. Wikipedia.

Since the pressure in the skirt is greater than the pressure produced by the weight of the hovercraft, an upward force is created. Or better yet, a source program in the memory of a given computer can be accessed remotely by people on terminals that can be thousands of miles away from the computer itself. Pf long did the hovercraft hover?

How does a Hovercraft use Aerodynamics to hover? by Parmveer Gahunia on Prezi

For example, if it took three breaths to blow the balloon up as large as you safely could, use only two breaths or a little less to inflate it this time. Compare the hovercraft’s performance over different surfaces. This is truly a four season vehicle. Cockpit noise is further reduced by enclosing and insulating the engine.

Good science fair projects have a stronger focus on controlling variables, taking accurate measurements, and analyzing data.

The large balloon held the largest amount hoveecraft air and should have allowed the hovercraft to stay aloft for the longest amount of time. I suppose they call it “low pressure” because it’s lower than “high pressure”.

Detach the balloon from the pop-top lid.

The top of the hovercraft, with the blower. You may print and distribute up to copies of this document annually, at no charge, for personal and classroom educational use.
