Sentences with phrase «of rocket propulsion»

Before one relegates the entire field of rocket propulsion to engineering you really have to understand the history of nozzle development, e.g. Like gHz frequency digital modulators it's pretty much (at least was initially) more of an art than a science, let alone an engineering challenge.

Musk, the chief executive of electric car maker Tesla Inc (tsla) and rocket company SpaceX (spacex), recently started the Boring Company to build transport tunnels for the system, which he says would be far faster than current high - speed trains and use electromagnetic propulsion.

They all share the goal of replacing rocket propulsion with the traversal of a fixed structure via a mechanism not unlike an elevator in order to move material into or beyond orbit.

So far, NASA's efforts have centered mainly on sorting out the aerodynamics of the CEV and its rocket, along with a launch - abort system and a «service module» that stays attached to the CEV until shortly before reentry, providing it with power and propulsion.

There are many different types of rockets, and a comprehensive list can be found in spacecraft propulsion - they range in size from tiny models such as water rockets or small solid rockets that can be purchased at a hobby store, to the enormous Saturn V used for the Apollo program.

Instead of rocketing astronauts off into deep space, the Asteroid Redirect Mission would send a robotic spacecraft to a small asteroid, secure it (potentially by grabbing it and stuffing it into a giant high - tech bag) and tow it back to orbit the moon using a hyper - efficient kind of rocket engine technology called solar electric propulsion.

And at the NASA Jet Propulsion Laboratory, researchers are demonstrating how to fabricate a larger - scale starshade's delicate petals, fold the entire structure up inside a rocket, and deploy and unfurl it to the size of a baseball diamond.

> A propulsion module consisting of four stages, each with four Vulcain 2 rocket engines (now being readied for an upgrade of ESA's Ariane 5 rocket), to propel the spacecraft from low Earth orbit to Mars.

Compared with the roar of chemical rockets, electric propulsion produces only a gentle purr.

However, the launch wasn't a total success because a loss of hydraulic pressure meant the firm wasn't able to recover the rocket's propulsion modules as planned.

Two types of electric rockets are currently in use: the ion thruster, which generates thrust using a beam of positive xenon ions, and the Hall thruster, which uses xenon ions and electrons for propulsion.

A hybrid rocket propulsion system comprises propellants of two different states of matter, the most common configuration being a rocket engine composed of a solid propellant lining a combustion chamber into which a liquid or gaseous propellant is injected so as to undergo a strong exothermic reaction to produce hot gas that is emitted through a De Laval nozzle for propulsive purposes.

«We are going to start a revolution,» agrees Tom Mueller, vice president of propulsion, who formerly ran rocket - engine development for TRW, now part of Northrop Grumman.

«It would require rocket propulsion to inject a serious extra snap of acceleration beyond what's already occurring at 7000rpm»

Scientology and L. Ron Hubbard are not that interesting to me on their own, so I'm pretty sure I grabbed this book because I'm a fan of Jack Parsons — the guy who founded NASA's Jet Propulsion Laboratory and the blue - collar Jack who pioneered solid rocket fuel.
