Wind considerations

One of the frequently asked questions we get is “how secure is the sHeli-Port when exposed to strong winds?”

To answer this question, New Jersey Institute of Technology performed wind tunnel and CFD (computational fluidic dynamics) testing. They analyzed the wind load characteristics at wind speeds up to 100 mph and from 8 directions. Headwinds, crosswinds, tailwinds and positions in between were tested with the case fully open, fully closed and several partially open conditions. The testing also simulated the effects of a helicopter hovering directly over the open unit.

The CFD results are similar to those obtained in the wind tunnel, thus adding confidence to the performance conclusions. The testing assumes the units are both unsecured and weightless. Since the actual weight is a bit over 4000 pounds, testing results are conservative when compared to real life results.

Due to its aerodynamic shape, unsecured units should not move in winds up to 100mph, except for a broadside wind over 80mph. Nevertheless, we recommend users anchor/secure the unit anyway!

Our unit in Virginia Beach remains undamaged after at least one hurricane and two tropical storms. That unit is secured by hammering two 3-foot stakes into the ground and attached directly to the sHeli-Port on each side.

Of course the only way to make sHeli-Port absolutely hurricane proof is to move it completely out of the hurricane zone. That’s not hard to do either!
