Could a helicopter work underwater?

Could a helicopter work underwater?

Helicopters can be designed to withstand limited contact with the surface of a body of water. The 1958 Vertol HUP-2 was an amphibious development of the twin-rotor Piasecki H-25 which strengthened its hull and replaced lower nose windows with tough aluminum.

How fast does a helicopter sink in water?

Within seconds of impact the helicopter will be upside down, flooded, and heading for the bottom, sinking at a rate of nine to 13 feet per second.

Can you fly underwater?

A: Yes you could! IF it had engines built for underwater use, a plane could technically fly underwater. Since air is a fluid, just like water, a plane could produce lift underwater as well, by using Bernoulli’s principle.

Which animal can fly underwater?

Atlantic Puffins truly are remarkable birds. Puffins can swim underwater and fly in the air. They have evolved their high speed wings and their rudder like webbed feet enabling them to swim efficiently underwater, where they catch small fish including herring and sand eel.

What is the fastest speed underwater?

The British Spearfish torpedo designed to counter high-speed Russian submarines, such as the Alfa-class submarine, is reputed to have a speed in excess of 70 knots (130 km/h). The Russian rocket-powered supercavitating torpedo VA-111 Shkval is reportedly capable of speed in excess of 200 knots (370 km/h).

Could a submarine survive a tsunami?

Submarines are relatively unaffected by weather or tsunamis when submerged in deep open waters. Once a submarine is deep enough the conditions on the surface are not felt. However if a submarine has to go shallow or to periscope depth then conditions on the surface become a major concern.

How many torpedoes does it take to sink an aircraft carrier?

Okay, first the straight answer probably 2–4 mk 48 torpedos to sink most aircraft carriers. The Torpedo isn’t designed to hit the vessel, it blows up just below the keel, blasting away the water that supports the middle of the ship.

Can a rogue wave sink an aircraft carrier?

Most likely this would be a learning process, since aircraft carriers rarely deal with much movement even in fairly rough seas – a few people would probably be injured in the learning process. Absolutely! It will not sink.

How hard is it to sink an aircraft carrier?

It’s very difficult to sink a buoyant, thousand-feet-long ship that’s mostly made of steel. The U.S. Navy knows this from experience. In 2005, the Navy itself targeted the decommissioned carrier America in order to determine just how much punishment the vessel could withstand before slipping beneath the waves.

Can Iran sink a US aircraft carrier?

The recent oil tanker attacks last year in the Gulf of Oman reinforce the need to reestablish a highly visible U.S. naval deterrent in the Middle East.
