Rocket Concept Plasma Simulations Spaceflight Missions * The Lab The rocket system consists of three major magnetic cells, denoted as "forward," "central" and "aft." This particular configuration of electromagnets is called an asymmetric mirror. The forward end-cell involves the main injection of gas to be turned into plasma and the ionization subsystem; the central-cell acts as an amplifier and serves to further heat the plasma. The aft end-cell ensures that the plasma will efficiently detach from the magnetic field. Without the aft end-cell, the plasma would tend to follow the magnetic field and provide only a small amount of thrust. With this configuration, the plasma can be guided and controlled over a wide range of plasma temperatures and densities. To operate the rocket, neutral gas, typically hydrogen, is injected at the forward end-cell and ionized. Then it is heated to the desired temperature and density in the central-cell, by the action of electromagnetic waves, similar to what happens in microwave ovens. After heating, the plasma enters a two-stage hybrid nozzle at the aft end-cell where it is exhausted to provide modulated thrust.

Shop or Compare Prices For decades, the only means of space travel have been rocket engines that run off of chemical propulsion. Now, at the beginning of the 21st century, aerospace engineers are devising innovative ways to take us to the stars , including light propulsion nuclear-fusion propulsion and antimatter propulsion. A new type of spacecraft that lacks any propellant is also being proposed. This type of spacecraft, which would be jolted through space by electromagnets , could take us farther than any of these other methods. Source: NASA Electromagnetic propulsion could take us to the heliopause at a speed unachievable by conventional spacecraft. When cooled to extremely low temperatures, electromagnets demonstrate an unusual behavior: For the first few nanoseconds after electricity is applied to them, they vibrate.

Home About Us The Hamilton Waterjet Model Range ... Members Hamilton Jet Pioneers of Waterjet Propulsion In 1953, on a shallow fast flowing river in the back country of the South Island of New Zealand, a small boat overcame the forces of nature to travel upstream against the current. The boat was a Hamilton Jetboat, and is recognised as the genesis of the modern waterjet propulsion system. Today, waterjets are the preferred propulsion choice for a wide range of pleasure and commercial craft where high efficiency, outstanding manoeuvrability, shallow draft capability and low maintenance are key requirements.

NEAR The Near Earth Asteriod Rendezvous (NEAR) Spacecraft and Aerojet Artist's depiction of NEAR spacecraft in flight near asteroid. Aerojet built the propulsion system for the NEAR spacecraft which is performing flyby scans of various asteroids in the solar system. We believe that this is the only Aerojet designed interplanetary spacecraft propulsion system ever flown. The gentlemen to the rightplayed a key role in the success of this important mission. Pictured from left to right are: Doug Anderson, Dave Gallet, Sam Wiley, Kip Lucas NEAR Mathilde/Eros Journey Using Aerojet Propulsion System Johns Hopkins University Applied Physics Laboratory (APL) gave the green light and a $9 million contract to Aerojet to develop the propulsion system for NASA's first Discovery Program . Combining both previously proven and new components, the 284-pound system will propel the NEAR spacecraft through small disturbances, as well as deep space maneuvers. The three-year mission will rendezvous with asteroid 433 Eros on February 6, 1999. Aerojet's propulsion system includes seven Fine Velocity Control (FVC) thrusters that fire periodically to hold the spacecraft steady. "There are reaction or momentum wheels that become wound up sort of like small springs after making adjustments due to wind or other elements to keep the vehicle on track," said Program Manager Eric Motz. "Our smaller one-pound thrusters are fired to counter the spacecraft's torque and thus, allow the wheels to unwind." There are also five-pound FVC thrusters that are used for small spacecraft velocity corrections and provide 3-axis stability control during large thruster firings.

90. Canonical List Of Space Transportation Methods Attempts to list all known space propulsion methods. http://www.geocities.com/danielravennest/CanonicalList.html

Canonical List of Space Transportation and Engineering Methods Version 0.79 July 26, 2001 by Dani Eder DaniEder@aol.com This document is a an attempt list of all known space transport and space engineering methods. It includes only those methods whose underlying physical principles are understood (i.e. no Star Trek warp drives). It is the product of a number of years of collecting and, occasionally, inventing them. I am motivated by a desire to see civilization expand into space and my frustration by the slow pace of progress to date. Most current space vehicles and projects use techniques that existed in the 1950's and 1960's. Some new ideas were developed as early as 1960, but have not been put into used even today. From the 1970's to today many additional ideas have been generated. Most of these have received scant attention. By disseminating information on these ideas, I hope others will realize the vast untapped potential contained in these ideas. This draft (version 0.79) lists all the concepts I am aware of, with at least a basic description of each. As you can tell by the version number, which is less than one, this is still very much a work in progress. Later versions of this document are intended to flesh out each method with improved descriptions and current references. If you know of a method which is not on this list, I would appreciate being informed of it. If you have references or text descriptions on a concept, they would be appreciated also. Some related information on the basics of space transport, the forces and energies used, and space project engineering are included. Editorial comments and material that needs lots of editing appear in square brackets.

Defining the problem Mars Direct vs. Earth Orbit Propulsion efficiency of an engine Different types of rocket engines Nuclear Propulsion Pay-Offs of nuclear propulsion systems ... Propulsion Links Propulsion Once the main technological obstacles to be overcome to make space exploration a reality (in the early days of the space program few were confident that man would ever develop a booster capable of propelling a human being into Earth orbit, much less to get him to the Moon), the propulsion system to be utilized becomes once more a major determinant in a manned mission to Mars. The enormous distances involved, the need to reduce the mission duration as much as possible for medical reasons, the weight constraints imposed by the existence of a manned crew and its life support system all make this choice a crucial one, a "go-no go" decision in terms of design. Defining the problem : Mars Direct vs. Earth orbit The problem must first be defined in order to start analyzing different alternatives for the propulsive system. We know for sure that we want to get from Earth to Mars, land there and come back to our home planet. But where will be launch from? The two alternatives have been extensively studied.
