Title: Re: Underwater airplane Post by: AnjanBabu on September 23, 2013, 06:49:53 PM There's an underwater glider kind of semi-autonomous ROV too, looks more like a tropedo with abnormally huge fins.
I tried searching for articles on it, sadly, couldn't find any. Title: Re: Underwater airplane Post by: RCNeil21 on September 23, 2013, 07:22:57 PM Couldnt this also be called a hydroplane. :headscratch:
Title: Re: Underwater airplane Post by: lastRites on September 24, 2013, 07:26:34 AM Nope :P
"A hydroplane (or hydro, or thunderboat) is a fast motorboat, where the hull shape is such that at speed, the weight of the boat is supported by planing forces, rather than simple buoyancy." This is a very fast submersible.. Title: Re: Underwater airplane Post by: rcrcnitesh on September 24, 2013, 07:30:26 AM also for steeamlining
drag is a frictional force exerted by liquids and gases for reducing this force streamlining is used read it from my science t.b.

I thought that as anwar sir called it a underwater airplane it could be also called a hydroplane, unfortunately that term already describes another water vehicle. Title: Re: Underwater airplane Post by: AnjanBabu on September 24, 2013, 12:41:12 PM I don't understand the "plane" part in Aeroplane and Hydroplane. Aerofoils/Hydrofoils don't really have a plane surface. ???
