The NPS rocket corer : a first generation rocket powered coring tool
npsrocketcorerfi00pier.pdf (1.406Mb)Abstract
A rocket motor powered corer has been designed and built. Limited tests of the rocket corer, conducted in a sand-silt-clay bottom at a depth of 100 feet off Pitas Point in Ventura County, showed promising results. It has been demonstrated that available rocket motors can be used to drive coring devices in relatively shallow water. Further tests are warranted to determine the maximum depth that rocket-powered instruments may be used. It presently appears possible that rocket motors may be used as a general source of power for varied underwater applications

Orbital transfer in minimum time
(Monterey, California. Naval Postgraduate School, 1962-08); Naval Postgraduate School (U.S.) Research paper ; no. 34.The problem of orbital transfer discussed here is that of scheduling the direction p of constant momentum thrust of a rocket, which loses mass at a constant rate, so that it transfers to an earth satellite orbit, with ... -
The ignition transient in small solid propellant rocket motors of practical configuration
(Princeton, New Jersey; Princeton University, 1967);An understanding of the ignition transient of a solid propellant rocket motor becomes increasingly more important as larger and more sophisticated solid propellant rocket motors are developed. Cost considerations alone ... -
Mars Mission
(2004-12-03);This interactive exercise allows students to test their knowledge of orbital mechanics by sending a rocket to Mars. They will have to estimate the time in space, the phase between earth and Mars at the time the rocket is ...
