How does Super cavitation work?
How does Super cavitation work?
Supercavitation. The fundamental idea behind supercavitation is surprisingly simple. When water is forced around an object, such as a ship’s propeller, at high speeds the pressure drops around the trailing edge, and if it drops below the water’s vapour pressure, bubbles are formed in a process known as cavitation.
What is the world’s fastest torpedo?

How do you create a Supercavitation?
In principle, supercavitating objects can be maneuvered using various methods, including the following:
- Drag fins that project through the bubble into the surrounding liquid (p.
- A tilted object nose.
- Gas injected asymmetrically near the nose to distort the cavity’s geometry.
Does the US have a Supercavitating torpedo?
Is there a future for the supercavitating torpedo? The U.S. has been working on such a weapon since 1997, apparently without a deployable weapon. Indeed, the U.S. Navy is currently in the process of upgrading the venerable Mark 48 submarine torpedo for service into the foreseeable future.
What’s the fastest submarine?
Soviet submarine K-222

How does cavitation damage?
Severe cavitation destroys the parts it contacts. Cavitation damage can also reduce performance. Additionally, air pockets in the impeller can cause considerable hydraulic imbalance and resulting vibration. As the impeller is eroded, the uneven wear may cause further imbalance and vibration.
How fast do submarine missiles go?
The Russian rocket-powered supercavitating torpedo VA-111 Shkval is reportedly capable of speed in excess of 200 knots (370 km/h). German press reports of an underwater anti-torpedo missile named Barracuda that allegedly reaches 430 knots (800 km/h).
How much does a modern torpedo cost?
| Mark 48 torpedo | |
|---|---|
| Manufacturer | Gould/Honeywell (Mod 1) Hughes Aircraft (ADCAP) Westinghouse Naval Systems Cleveland Ohio |
| Unit cost | $894,000 (1978 USD) $3,500,000 (ADCAP) (1988) $3,800,000 (CBASS)(2005 USD) |
| Specifications | |
| Mass | 3,434 lb (1,558 kg) (original), 3,695 lb (1,676 kg) (ADCAP) |
Which is faster submarine or ship?
Nuclear power allows submarines to go faster than surface ships. (This may be true.) The fastest submarine is claimed to be the Soviet K-162, launched in 1969, with a top speed of 44.7 knots (82.8 km/hr). Nuclear powered aircraft carriers have disclosed top speeds around 33 knots.
Can submarines go fast?
There are established reports and manufacturer’s claims that would indicate two (or perhaps more) submarines are capable of speeds exceeding 30 knots (56 km/h). In 1965, USS Albacore reported a speed of 33 knots (61 km/h), but this was not an official record.
What country has the best submarine?
Currently top 10 attack submarines in the world are these:
- Nr.1 Seawolf class (USA)
- Nr.2 Virginia class (USA)
- Nr.3 Astute class (United Kingdom)
- Nr.4 Graney class (Russia)
- Nr.5 Sierra II class (Russia)
- Nr.6 Improved Los Angeles class (USA)
- Nr.7 Akula class (Russia)
- Nr.8 Soryu class (Japan)
What is supercavitation and how does it work?
Supercavitation is the use of cavitation effects to create a bubble of gas or vapor large enough to encompass an object traveling through a liquid, greatly reducing the skin friction drag on the object and enabling high speeds. Current applications are mainly limited to projectiles or fast supercavitation torpedoes,…
What is supergravity theory in physics?
In theoretical physics, supergravity (supergravity theory; SUGRA for short) is a modern field theory that combines the principles of supersymmetry and general relativity; in contrast to non-gravitational supersymmetric theories such as the Minimal Supersymmetric Standard Model.
