Décavitator : le record du monde de Mark Drela

Vidéo du record de monde de VPH aquatique établi le 27 octobre 1991 avec 18,5 noeuds. Le Décavitator est un hydroptère propulsé par une hélice aérienne. L'aile sous-marine propulse l'engin hors de l'eau au-delà d'une certaine vitesse, ce qui permet de réduire les frottements et donc de gagner en vitesse.

One wrong move and its Decapitator

[jcgosselin]

So don't move (except your legs) !

:-)

wow that thing goes fast or is the video speeded up

[jcgosselin]

It IS fast. The Decavitator reached 18.5 knot (34 km/h or 21.3 mph). Only a japonese tandem went faster without using the wind or any engine.

also on water or not? i`m making my own hydrofoil, i`m puting foils on my kayak and i`ll put a 2 HP motor behind it

[jcgosselin]

Yes, the japonese tandem is the fastest Human Powered Vehicule on water (over 100 meter "flying" start). Good luck for your flying kayak!

This is a rare film of an historic event. Thanks for posting it. To see more hydrofoil actions, search in Youtube for: rvell7829

I'm interested to start a project for a HP ground effect vehicle. It's been done before, even to fly across the Channel. It was slow however, due to huge lift. I'd like to go with lower lift, to require and enable higher speed. Possibly faster than this.

In my ideas, I keep coming back to (partially) inflatible designs, for light weight and crash absorbtion.
