+ 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,

Tactical Systems Propulsion Aurora’s Propulsion research group has broad-based experience in all facets of aerospace propulsion, including reciprocating, electric, turbine, and rocket propulsion. Additional topics include use of heavy fuel in small engines, efficient propeller design, and unique propulsion designs for extreme environments. Distributed Engine Control Aurora and Georgia Tech are conducting research under an Air Force Research Lab (AFRL) Phase II STTR contract to explore the technology, costs, and benefits of distributed control for turbine engines, specifically turboprop and variable-pitch turbofan engines. Phase I efforts demonstrated the feasibility of a partially distributed control scheme with separate controllers on the engine core and fan, where the controllers are linked by a supervisory controller. In Phase II, Aurora and Georgia Tech are further developing the distributed controller from Phase I to cover safe performance during non-standard operations (including sensor failure etc.), culminating in a static engine test of a small turbo-prop engine controlled by the distributed adaptive controller. Very High-Altitude Propulsion System (VHAPS) Aurora is currently conducting a DARPA-sponsored SBIR Phase II project to examine propulsion alternatives for very high altitude UAV use. DARPA’s initial interest was in low-speed, long-endurance flight at altitudes. Aurora showed through analysis that higher operating speeds were possible while still retaining specific fuel consumption numbers necessary for operational utility.

For a general explanation of the challenges and approaches of interstellar flight, please visit the companion website: Warp Drive: When? The Warp-When site is written for the general public and uses icons of science fiction to help convey such notions. This website, on the other hand, is intended for scientists and engineers. This research falls within the realm of physics instead of technology , with the distinction being that physics is about uncovering the laws of nature while technology is about applying that physics to build useful devices. Since existing technology is inadequate for traversing astronomical distances between neighboring stars (even if advanced to the limit of its underlying physics), the only way to circumvent these limits is to discover new propulsion

Spacecraft propulsion From Wikipedia, the free encyclopedia Jump to: navigation search A remote camera captures a close-up view of a Space Shuttle Main Engine during a test firing at the John C. Stennis Space Center in Hancock County, Mississippi Spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites . There are many different methods. Each method has drawbacks and advantages, and spacecraft propulsion is an active area of research. However, most spacecraft today are propelled by forcing a gas from the back/rear of the vehicle at very high speed through a supersonic de Laval nozzle . This sort of engine is called a rocket engine All current spacecraft use chemical rockets ( bipropellant or solid-fuel ) for launch, though some (such as the Pegasus rocket and SpaceShipOne ) have used air-breathing engines on their first stage . Most satellites have simple reliable chemical thrusters (often monopropellant rockets ) or resistojet rockets for orbital station-keeping and some use momentum wheels for attitude control . Soviet bloc satellites have used electric propulsion for decades, and newer Western geo-orbiting spacecraft are starting to use them for north-south stationkeeping. Interplanetary vehicles mostly use chemical rockets as well, although a few have used

Launched on Oct. 24, 1998, Deep Space 1 will be the first spacecraft to actually use ion propulsion to reach another planetary body. The engineering that makes this possible represents a journey that started more than half a century ago, when modern rocketry was invented.

18. Propulsion Although the engines will vary individually as far as component capabilities, there are 4 basic types of airbreathing engines the turbojet, the turboprop, the turbofan, and http://wings.avkids.com/Book/Propulsion/instructor/types-01.html

Types of Air-Breathing Engines page 1 Turbojet: As discussed in the History section, the turbojet was the original jet engine design. The development of the turbojet revolutionized transportation. It greatly reduced the expense of air travel and contributed to a major improvement in aircraft safety. In addition, it allowed for faster cruise velocities up to supersonic speeds. It had a much higher thrust per unit weight ratio than the early piston-driven engines, which led directly to longer ranges (flight distances) and higher payloads (more passengers and baggage). As it happened, it also turned out to have lower maintenance costs. The typical turbojet engine has all 5 of the components described in the previous section: an inlet, a compressor, a combustor, a turbine, and a nozzle. The figure below shows a basic turbojet schematic with the 5 components clearly identified. To get an increased thrust, an afterburner can be added to the turbojet. The figure below is the turbojet with an afterburner. Unfortunately, the increased thrust comes at the expense of an increased fuel consumption. Typically, transport aircraft (both civilian and military) do not use afterburners. Even fighters with afterburners use the afterburners judiciously; they are turned on for only a brief burst of thrust. If a pilot runs too long with the afterburner on, he or she risks running low on fuel before the mission in completed. The turbine inlet temperature is a primary design limitation for the turbojet. In order to get a hotter burn in the burner, beyond the maximum temperature allowable for the turbine, the design engineer may use a technique known as turbine blade cooling. This technique bleeds a small amount of the cooler air in the compressor, which then bypasses the burner and is fed back into the first 1 or 2 rows (called stages) of turbine blades. Typically, the air is fed through hollow turbine blades and pushed out along the trailing edge of the blade. Turbine blade cooling has been used successfully to increase the turbine inlet temperature above the maximum allowable temperature. Unfortunately, the engine performance is very sensitive to the amount of cooling air, and increased thrust is often at the expense of major cooling penalties.

19. Space Plasma Physics Modelling Page An advanced plasma propulsion system that will create a large scale magnetic bubble around the spacecraft to ride the solar winds. http://www.ess.washington.edu/Space/propulsion.html

Advanced Electric Propulsion Chemical rockets have limited application for space applications due to the fact that the fuel is relatively slow (low specific impulse) relative to the speeds needed to move efficiently about the solar system. As a results chemcial systems are massive, and the trip times for missions are very long. Research at UW in this area is for the development of faster propellants that can provide substantial reductions in cost and trip time. To achieve these efficiencies plasma systems (i.e. charged particles) are required where electric and magnetic field can be used to accelerate the plasma propellants to speeds more than an order of magnitude faster than can be achieved by chemical rockets. The systems below detail devices under active development. Cast of Characters: Robert M. Winglee Areas of Active Interest: High Power Helicon is an electrodeless plasma thruster that is able run at kW to 100's kW to produce thruster levels as high as several Newtons of force, at high power and gas effciency. Mini-Magnetospheric Plasma Propulsion (M2P2) is a system that can leverage energy from the solar wind to augument the onboard propulsion for spacecraft while minimizing the spacecraft power requires. Potential for radiation shielding is still under investigation.
