| An artist's concept of a power-augmented ram landing craft (PARLAC) offloading amphibious tractors (LVT) onto a beach. The PARLAC, which has the capability of achieving high speeds and has good shore-landing capability, presently in the testing stages of research and development. |
I didn`t know the PARLAC.
ReplyDeleteI have looked for in Internet and I have found the following pics and docs:

Regards,
I love it and cringe at it. On the one hand, a turbojet/turbofan (drawing shows a high-bypass turbofan) to shove air under the vessel to reduce draft/provide thrust? Awesome!
ReplyDeleteOn the other hand, hanging a jet engine waaay out front on two long arms? The vibrations that'd allow will be nightmarish, and the blade erosion and corrosion would be of epic levels. Even worse, what happens if you get a slug of solid water in there from a breaker? A duck is big enough to break fan blades, I hate to think what a few hundred pounds of water would do.
Turbofans eat water without problems ,but in any case this is a stupid concept ,and the pict of a sideways beached craft is just the icing on the cake.
Deletewe don't know what the draft of the boat is or the beach conditions. but even more importantly this is just an artist concept pic. the main thing is to show off the project, not necessarily illustrate the vehicle in action.
DeleteThis could work.
ReplyDeleteI'm thinking mounted on side pylons would be better.
Looks like super-sized INLS barge ferry. Pushing a lligher of that size and hull form at 90 kits is questionable, meaning high installed HP. Why not just fast landing craft of LCU size?
