Ultra Fast Escape of Shape-Changing Rockets Underwater


A study of cephalopods, like the squid and the octopus, shows that they have developed an ultra-fast escape mechanism based on first inflating and then deflating their shape while using the expelled water as a propelling jet. The mechanisms that allow control of the drag forces and flow energy recovery can be used to propel a shape-changing vehicle to match the performance of cephalopods.
