Learn the basics of designing, building and testing liquid fuel rocket engines Search E.R.P.S. Site: Experimental Rocket Propulsion Society This site best viewed from low earth orbit ... In the beginning ... The E.R.P.S. was founded in February of 1993 to gather together interested amateurs to learn about, design, build, and test liquid fuel rocket engines. The group early on decided to concentrate on developing and testing high density storable propellant combinations because they allowed the maximum amount of work to be done with the minimum amount of risk to life and limb. After research and consultations, high density Hydrogen Peroxide (H O ) was selected as the oxidizer of choice, with the intent to combine it with a high-density kerosene such as JP5 or regular Jet-A. HTP by any other name ... Peroxide, when catalyzed, produces steam (2 H O) and pure oxygen (O ) at high temperatures. Peroxide makes a fair mono-propellant when used in concentrations above 95% and there was historical experience (the British 'Black Knight' program of the late 60's and early 70's) to show that respectable performances and capabilities could be developed even at lower concentration when combined with a high density liquid hydrocarbon. The British, however, limited themselves by the catalyst they chose to work with, silver screens. Because the melting point of silver is low (936.93 o C), using peroxide at concentrations above about 85% generates a heat of reaction high enough to melt the silver and thereby reduce and eventually eliminate the "catalyst" from the reaction. The physical properties of the reaction and the type of catalyst used, therefore, limited their performance.

Oceanography Space Sciences Blow the Ballast! CyberMail ... Teachers' Corner Submarines: How They Work - Propulsion Manual The very first submarines depended on people for the energy to move. Cornelius van Drebbel, whose submarine was tested on the Thames in 1620 and reported to have carried the King of England on one of its dives, used oars to move itself along. The oars extended from the craft and leather gaskets sealed the point of their emergence. In the mid-1770s, David Bushnell built a submarine Turtle that used hand and foot cranks for propulsion. This one-person submarine, which was the first to be used during war, was very inefficient and exhausted its operator in a short time. Robert Fulton developed a three-person submarine Nautilus in the early 1800s that was the first to use diving planes to control depth. While submerged, it relied on a hand crank to move it along. For travel on the surface, the Nautilus was equipped with a sail.

The scientists who had raced to produce a bomb had also developed theories for a number of possible uses for the atom. Martin Mann lists a number of them in his book, Peacetime Uses of Atomic Energy. Ideas ranged from power generation, to nuclear excavation, to nuclear propulsion for vehicles on land, sea, and in the air. There were proposals for nuclear ships, nuclear locomotives, nuclear automobiles, and nuclear aircraft. It is this last proposal that is the topic for this paper, which will examine the technical and socio-political aspects of the United States Air Force's Aircraft Nuclear Propulsion (ANP) program and associated programs, including the reasons the ANP program was undertaken, and the reasons it was canceled after a decade of work.

Ion Engines Ion Engines are the most exciting new rocket propulsion system since the Chinese invented the rocket about a thousand years ago. Most rocket engines use chemical reactions for power. They combine various gases and liquids to form chemical explosions which push the rocket through space. Chemical rocket engines tend to be powerful but have a short lifetime. Ion Engines use electric fields instead of chemical reactions. Ion Engines tend to be much less powerful, but they are so efficient, they can last for years before running out of fuel. These activities should help you understand how Ion Engines work. Before you can understand the entire Ion Engine, you need to understand some basics about electric charges.

var firstLevel = ''; VASIMR Plasma Simulations Space Flight ... Reference Advanced Space Propulsion Laboratory HOME The Advanced Space Propulsion Laboratory is developing a new type of rocket technology, the Variable Specific Impulse Magnetoplasma Rocket. This plasma rocket drive is not powered by conventional chemical reactions as today’s rockets are, but by electrical energy that heats the propellant. The propellant is a plasma that reaches extreme temperatures — 50,000º and above. Some scientists call this the fourth state of matter. This new type of technology could dramatically shorten human transit times between planets (about 3 months to Mars). Not only will planetary missions be fast, but the plasma drive will propel robotic cargo missions with very large payloads (more than 100 tons to Mars). Trip times and payloads are major concerns when using conventional rockets. The laboratory was founded at NASA Johnson Space Center in December 1993. The lab director is NASA astronaut Dr. Franklin Chang-Diaz. He has been working on the development of a plasma rocket since 1979. Work began at Charles Stark Draper Laboratory then continued at the Massuchusetts Institute of Technology Plasma Fusion Center before moving to JSC.

Johnson Space Center FOREWORD The speculative "propulsion" concept described in this paper was presented at a special session of the 15th Joint AIAA/SAE/ASME Propulsion Conference (June 18-20, 1979), "Propulsion Concepts for Galactic Spacecraft". The concept was developed as the result of private, unofficial research. NASA is not involved in UFO research. However, the research which may be stimulated by this paper could result in the verification of essential elements of this concept and in feasibility studies concerning the development of a new generation of NASA spacecraft. - Alan C. Holt ABSTRACT A new propulsion concept has been developed based on a proposed resonance between coherent, pulsed electromagnetic wave forms and gravitational wave forms (or space-time metrics). Using this concept, a spacecraft "propulsion" system potentially capable of galactic and inter-galactic travel without prohibitive "travel times" has been designed. The "propulsion" system utilizes recent research associated with magnetic field line merging, hydromagnetic wave effects, free-electron lasers, laser generation of megagauss fields, and special structural and containment metals. Research required to determine potential, field resonance characteristics and to evaluate various aspects of the spacecraft "propulsion" design is described.

Now with Farther-Reaching 3mW-5mW Laser! 'Antigravity' Propulsion System Proposed By Bill Christensen posted: 15 February 2006 11:08 a.m. ET An 'antigravity' propulsion system was proposed at the Space Technology and Applications International Forum (STAIF) in Albuquerque on Febuary 14 by Dr. Franklin Felber. His new exact solution to Einstein's gravitational field equation gives hope to space enthusiasts that it might be possible to accelerate space craft to speeds approaching that of light without crushing the contents of the craft. If it works, it could be even better than apergy , as described by science fiction writer Percy Greg in 1880. Dr. Felber's paper states that a mass moving faster than 57.7 percent of the speed of light will gravitationally repel other masses lying within a narrow 'antigravity beam' in front of it. This "beam" intensifies as the speed of the mass approaches that of light. The paper shows how to use the repulsion of a body speeding through space to accelerate large spacecraft quickly while reducing internal tidal forces that could tear the cargo apart. The paper argues that the payload would "fall weightlessly" in an antigravity beam as it is accelerated to a substantial fraction of light speed.

The rocket nozzle not only controls the thrust level of the missile, but also provides thrust vector control to steer it. The U.S .military needs more capable tactical missiles to hit more sophisticated enemy aircraft and fast moving ground targets. WSPC's new rocket motor would significantly enhance American tactical missile capabilities. April 6, 2006 - The Air Force Research Laboratory has written an article on WSPC's work on a new Small Launch Vehicle (SLV) on its homepage. The SLV's propellant is WSPC's high performance, environmentally friendly, low cost, phase stabilized ammonium nitrate (PSAN) space booster propellant. Its unique SLV solid rocket motors provide real time controllable thrust with a unique expansion-deflection (E-D) exit cone. The E-D exit cone concept has been verified by CFD analysis and solid rocket motor static firings. The E-D exit cone also provides optimum expansion of the exhaust gases at all altitudes. This enables WSPC's SLV to be ground launched or air launched. These features give WSPC's SLV the highest level of mission versatility to deploy Common Aero Vehicles (CAV) or satellites. WSPC has been supported in this work with U.S. Air Force funding. For more information click here.

They are light and powerful and modern outboards are extremely quiet. The outboard provides a completely self-contained propulsion system from engine to transmission to shaft and propeller. They are most often mounted directly on the transom of the boat, however, you may find boat designs incorporating a motor well or bracket on which the motor mounts. The entire motor swivels about to provide easy steering as the turning propeller pushes the stern.
