(65) The essential quality that dictates the choice of this propulsion system is readiness. (66) Guidelines for LEA vehicle and its propulsion system design have been validated in mid 2009 by a critical design review. (67) Finally, comparative experiments prove that this design is feasible for improving swimming stability of flexible multi-joint underwater pisciform propulsion system. (68) The "yellowish-white liquid" sounds suspiciously like gasoline, and perhaps Vimanas had a number of different propulsion sources, including combustion engines and even "pulse-jet" engines. (69) The thin array of ice and dust particles lies at the far reaches of the Saturnian system and its orbit is tilted 27 degrees from the planet's main ring plane, Nasa's jet propulsion laboratory said. (70) The motivation of this thesis is to design a fish-like propulsion and control method, which can be used on the UV, through the research on the swimming theory of fish. (71) Based on motion similarity of micro robot drive fin and fish caudal fin, this paper discusses fish muscle hydrodynamics, and analyzes propulsion force produced by biomimetic fish-like drive fin. (72) Beginning in July 1958, with the creation of NASA, work on nuclear rockets became the provenance of the Space Nuclear Propulsion Office. (73) To overcome the difficulties on acquiring enough fault modes from ground and flight test data, the failure process for liquid propellant rocket propulsion systems was modeled. (74) That's Richard Gross , of NASA's Jet Propulsion Laboratory . He is the scientist who performed the calculations. (75) It is worth noting that Nikko manufactures its own award-winning gearless lift propulsion machine, though it is not clear whether one is used as a replacement motor here. (76) The company paid me while they trained me, and eventually I became a drafter of engineering drawings for the Aircraft Carrier Propulsion Overhaul Department. (77) Scientists and engineers at the control center in the Jet Propulsion Laboratory in Pasadena, California, cheered.
