The jet pack is a kind of pre-war sci-fi goals that the chilly gentle of rational consideration reveals to be a horrible concept. Who desires to prepare dinner their legs with scorching exhaust whereas careening uncontrolled? No one. But it’s such an iconic concept, we will’t get away from it. What if there was a greater atmosphere, one the place your jetpack goals may come true? [CPSdrone] has discovered one: the world’s oceans, and have taken that revelation to construct the world’s quickest underwater jetpack.
Underwater? Yeah, water drag is worse than air drag. However there are two massive benefits: one, people are pretty buoyant, so that you don’t want combat gravity with rocket thrust, and two, the excessive density of water makes small, electrical props an affordable proposition. The electrical ducted followers on this “jetpack” every produce about 110 kilos of thrust, or simply over 490 N. The primary benefit is helped additional by the buoyancy offered by the air-filled “hull” of the jetpack. That’s mandatory as a result of whereas the motors may be rated for submersion, however the remainder of the electronics aren’t.
Alas, carrying the gadget on the again is significantly much less hydrodynamic than hanging on behind in the usual ‘water scooter’ configuration. Whereas they’re in a position to go quicker than a swimming human, the ESCs weren’t in a position to deal with the motors full energy so we will’t inform you if this gadget would enable [CPSdrone] to outrun a shark with these 220 lbf on faucet, which was the design objective. Apparently they’re engaged on it.
From the testing finished on-screen, it’s secure to say that they’d no less than want to hold on behind to get their desired velocity objectives, and abandon their jet pack goals simply as we landlubbers had been compelled to do way back. Nicely, a few of us, anyway.
