+ Text Only Site + Non-Flash Version + Contact Glenn Welcome to the Beginner's Guide to Propulsion What is propulsion? The word is derived from two Latin words: pro meaning before or forwards and pellere meaning to drive. Propulsion means to push forward or drive an object forward. A propulsion system is a machine that produces thrust to push an object forward. On airplanes, thrust is usually generated through some application of Newton's third law of action and reaction. A gas, or working fluid , is accelerated by the engine, and the reaction to this acceleration produces a force on the engine. A general derivation of the thrust equation shows that the amount of thrust generated depends on the mass flow through the engine and the exit velocity of the gas. Different propulsion systems generate thrust in slightly different ways. We will discuss four principal propulsion systems: the propeller,

Laser Launch Systems The Lawrence Livermore National Laboratory's Special Studies Program (within The Advanced Technology Program (ATP) of O Division) has examined alternative spacecraft propulsion concepts to meet performance or mission objectives. Laser propulsion concepts have been described for several decades. The laser beam is used to heat a propellant with the energetic expansion driving the craft. A series of ATP devised tests were conducted in which a laser beam was directed at a pusher plate with machined paraboloid dimples. Light was focused by each dimple on a spot behind the plate. The focused beam heated air pockets and the expanding pockets imparted a thrust to the plate. This *concept* provides respectable thrust in the atmosphere. In *space* (vacuum) the dimpled plate is jettisoned to expose a block of solid propellant which is ablated by the laser beam to produce thrust.

6. Basic Of Space Flight: Rocket Propulsion An overview of rocket propulsion including basic thrust equation, engine design considerations, and example problems. http://www.braeunig.us/space/propuls.htm

ROCKET PROPULSION Thrust Conservation of Momentum Specific Impulse Power Cycles ... Staging Isaac Newton stated in his third law of motion that "for every action there is an equal and opposite reaction." It is upon this principle that a rocket operates. Propellants are combined in a combustion chamber where they chemically react to form hot gases which are then accelerated and ejected at high velocity through a nozzle, thereby imparting momentum to the engine. The thrust force of a rocket motor is the reaction experienced by the motor structure due to ejection of the high velocity matter. This is the same phenomenon which pushes a garden hose backward as water flows from the nozzle, or makes a gun recoil when fired. Thrust Thrust is the force that propels a rocket or spacecraft and is measured in pounds, kilograms or Newtons. Physically speaking, it is the result of pressure which is exerted on the wall of the combustion chamber. The figure to the right shows a combustion chamber with an opening, the nozzle, through which gas can escape. The pressure distribution within the chamber is asymmetric; that is, inside the chamber the pressure varies little, but near the nozzle it decreases somewhat. The force due to gas pressure on the bottom of the chamber is not compensated for from the outside. The resultant force F due to the internal and external pressure difference, the thrust, is opposite to the direction of the gas jet. It pushes the chamber upwards.

But jet propulsion is actually older than the Flintstones. It's a standard means of locomotion for jellyfish, the earliest animals to swim the seas using muscles. Jellies have been jet-propelling for at least 550 million years, yet only recently have scientists begun to understand how the challenges of moving in fluid have shaped jellyfish evolution. This Scyphozoan jellyfish, with its UFO-shaped bell, moves to a slower rhythm than its smaller, rocket-shaped relatives. New studies link jellyfish means of locomotion to body size and shape. iStockphoto Jellyfish invented muscle-powered movement, a feat that allowed them to diversify into a number of ecological nooks and crannies. But jelly muscles are relatively meager and the jet-pack method of motion requires serious strength. That has presented a mystery about how some species of jellyfish can get so big. New studies have begun to explain how enormous gelatinous creatures muster the strength to swim. The answers may lead to novel designs for underwater vehicles and are prompting scientists to rethink how to harness energy from wind currents. If you've seen a jellyfish washed up on the beach, its brawn probably wasn't the first thing that struck you. Their bell-shaped bodies are mostly gelatinous goo, surrounded by a network of nerves and a paper-thin layer of tissue. But on the interior wall of the bell is a layer of muscle. Contracting this muscle ejects water from the opening at the base of the bell, propelling the animal on its path.
