Discussion Overview
The discussion revolves around the concept of supercavitating projectiles underwater, specifically focusing on the feasibility of torpedoes achieving Mach 1 speeds. Participants explore theoretical possibilities, existing technologies, and the implications of supercavitation in underwater propulsion.
Discussion Character
- Exploratory
- Debate/contested
- Technical explanation
Main Points Raised
- One participant questions the validity of claims regarding USSR-developed torpedoes that could reach Mach 1, seeking mathematical support for such assertions.
- Another participant expresses skepticism, noting that Mach 1 in water is significantly faster than current torpedo speeds, citing specific figures (1482 m/s at 20°C).
- A participant mentions theoretical discussions about torpedoes creating an air pocket to reduce drag, although they are uncertain about practical implementations or tests.
- Reference is made to another thread discussing a torpedo in service that travels at 100 m/s, which is noted to be below the speed of sound in water.
- Concerns are raised about the actual speed of the mentioned torpedo, emphasizing that 100 m/s is still far from Mach 1.
- One participant speculates whether heating the front of a torpedo could generate a gas bubble to enhance speed.
- A participant provides links to external sources discussing supercavitation and related engineering feats, indicating interest in the topic's complexity.
Areas of Agreement / Disagreement
Participants exhibit disagreement regarding the feasibility of achieving Mach 1 underwater, with some expressing skepticism about current technologies and others exploring theoretical possibilities. The discussion remains unresolved with multiple competing views.
Contextual Notes
Participants reference specific speeds and theoretical concepts without reaching a consensus on the practicality or existence of Mach 1 torpedoes. There are also mentions of external sources that may provide additional context but do not clarify the ongoing debate.
