ADVANCED PROPULSION CONCEPTS AT THE JET PROPULSION I~A~ORATORy
Current interest in advanced propulsion within NASA and research activities in advanced propulsion concepts at the Jet Propulsion Laboratory are reviewed. The concepts,which include high power plasma thrusters such as lithiun~-fueled Lorentz-Force-Accelerators,MEMS-scale propulsion systems, in-situ propellant utilization techniques, fusion propulsion systems and methods of using antimatter, off...
متن کاملResearch at Jet Propulsion Laboratory (JPL)
AI research at JPL started in 1972 when design and construction of an experimental “Mars Rover” began. Early in that effort, it was recognized that rover planning capabilities were inadequate. Research in planning was begun in 1975, and work on a succession of AI expert systems of steadily increasing power has continued to the present. Within the group, we have concentrated our efforts on exper...
متن کاملAstrobiology. Ames's proposal for lab triggers battle at NASA.
Officials at NASA's Ames Research Center in Moffett Field, California, would like to trade the use of part of their land for a new building largely dedicated to NASA's nascent astrobiology program, the core of which is a 2-year-old virtual institute based at Ames. Although some scientists applaud the idea, others say that it undermines the idea of a virtual institute and that operating costs wo...
متن کاملJet propulsion without inertia
A body immersed in a highly viscous fluid can locomote by drawing in and expelling fluid through pores at its surface. We consider this mechanism of jet propulsion without inertia in the case of spheroidal bodies and derive both the swimming velocity and the hydrodynamic efficiency. Elementary examples are presented and exact axisymmetric solutions for spherical, prolate spheroidal, and oblate ...
متن کاملJet Propulsion Engines
The jet propulsion engine is used for the propulsion of aircraft, m issile and submarine (for vehicles operating entirely in a fluid) by the reaction of jet of gases which are discharged rearward (behind) with a high velocity. As applied to vehicles operating entirely in a fluid, a momentum is imparted to a mass of fluid in such a manner that the reaction of the imparted momentum furnishes a pr...
