(61) With the development of spaceflight engineering, more and more micro - satellites have adopted propulsion system.

(62) Engineers at the Jet Propulsion Laboratory are creating a micro rover.

(63) Propulsion must enjoy priority in research and development of launch vehicles.

(64) So people have paid their attention on robofish propulsion system which has more advantages than propellers.

(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(sentencedict.com), 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.

(78) Discussed braking problem while electric propulsion system slowdown and shut down.

(79) The ship to paddle blade wheel OARS bihan OARS, put the intermittent push to Samuel whirly propulsion (the OARS wheel for continuous operation).

(80) His research for NASA's Jet Propulsion Laboratory as a geophysicist helps launch spacecraft at the correct time and position to reach their exact destinations.

(81) The author refers to lots of literatures and datum on internet, and understands the structure and working process of the podded propulsion.

(82) Huangqi markedly facilitated small intestinal propulsion in normal mice motility was delayed by atropine and isoproterenol.

(83) From propellers to jet propulsion to rocketry, men are now walking in outer space and exploring the surface of the moon and the Mars.

(84) This paper describes the ALSTOM products used in the Diesel-electric propulsion system , Mermaid Pod system , dynamic positioning system and their influences on the ship performances.

(85) Laser power beaming and propulsion, on the other hand,(www.Sentencedict.com) would require sustained average power output from lasers of megawatts to gigawatts .

(86) The SPC-II fish robot prototype is an experimental platform which validates the stability, high efficiency and maneuverability by utilizing the caudal fin propulsion mechanism.

(87) We established the mathematics model of the, whole torpedo thermodynamic propulsion system which adopt unclose cycle form.

(88) In its current structure, the 12 chapters cover all aspects of shipping from construction and fire protection to nuclear propulsion, dangerous cargo, safety management and maritime security.

(89) The fundamentals, developments and applications of Nuclear Thermal Rocket Propulsion will be discussed here.

(90) When a ship goes in waves, propulsion thrust will fluctuate remarkably.
