The rocket engine power plant runs at a 35% thermal efficiency, versus 55% for conventional gas-fired plants.
The oxygen that remains is burned with fuel and water in a chamber modeled after a rocket engine.
For those tests, Virgin will be testing the aerodynamics of its SpaceShipTwo with its rocket engine fully installed.
FORBES: Virgin's Top Frequent Flier Gets To Fly For Free - Into Space
On release, SS2 will then ignite a rocket engine to climb to a maximum altitude of about 361, 000ft (110km).
The gravity assist would allow a safe return to Earth even if the spacecraft's main rocket engine failed, Professor Longuski said.
The amount of radiation likely won't change unless there's a rocket engine developed that can speed up the interplanetary ride, researchers said.
Its disruptive technology is a novel air-breathing and rocket engine that would enable the ship to go to space in one leap.
The vehicle was dropped from a carrier aircraft high above California's Mojave Desert and ignited its rocket engine to go supersonic for a few seconds.
In recent years, it extended a rail line to a point nearby the facility and it tested a large rocket engine at the facility in November 2010.
On a hot June evening at a ramshackle former gliderport 30 miles east of Dallas, John Carmack's rocket engine lit up with its blue flame spewing from the nozzle.
It was the first loss of a Progress freighter in more than 30 years of operation, according to the report, which said the cause was believed to be a rocket engine failure.
Japan is also working on a new rocket engine using composite materials from Ishikawajima-Harima Heavy Industries and the first infrared seekers, made by Fujitsu, that can see in two colors to distinguish decoys from warheads.
Japan is also working on a new rocket engine using composite materials (Ishikawajima-Harima Heavy Industries), the first infrared seekers (Fujitsu) to see in two colors to distinguish decoys from warheads, and a kinetic warhead that rams into missiles directly rather than exploding nearby.
The December 2010 flight, much shorter and less demanding than this weekend's effort, wasn't without problems: the rocket experienced some engine hiccups on ascent.
It will be powered by a combination of a hybrid rocket and a jet engine from a Eurofighter-Typhoon.
The key is a unique motor, the Sabre, which serves as jet engine and rocket rolled into one.
Personally, I have my eye on an even smaller jet, the rumored single-engine, four-seat pocket-rocket from Cirrus Design. (If the one engine fails, pull a lever and a parachute will float you and the plane to a soft landing.) One of the two brothers who founded Cirrus told me the Cirrus jet would go 300 knots, or 345 miles per hour.
The engine was shut down immediately, and the course of the rocket given a readjustment to compensate for the lost engine.
FORBES: SpaceX Rocket Loses An Engine; Mission Still Looking Good
It begins with an evocative description of George Stephenson's Rocket, a famous early steam engine, and traces the developments needed to make each of its individual components possible.
The latter include, for example: supercomputers, advanced machine tools, fiber optic and other sophisticated telecommunications gear, jet engine hot sections, rocket propulsion and guidance components, "stealth" technology, to name a few.
CENTERFORSECURITYPOLICY: Clinton Lets Trade Trump Security, Again
With similar styling to the previous Viper, albeit with an all-new carbon-fiber and aluminum skin, the new Viper comes blazingly powered by an all-aluminum, mid-front-mounted 8.4-liter V10 engine that puts a rocket-like 640 horsepower and 600 pound-feet of torque to the pavement.
The first attempt to launch the rocket was halted Saturday when a flight computer detected high pressure in an engine combustion chamber.
When the rocket at last blasted off on November 15th, the first-stage engine cut out prematurely, forcing the ground crew to destroy it for safety reasons.
M-5 rocket last month seems to have been caused by a damaged graphite nozzle in the first-stage engine.
With its cluster of four Taepodong 1 engines powering the first stage, and either a similar engine or a Scud motor for the second stage, the Taepodong 2 is unquestionably a rocket to be reckoned with.
The sports car look of the cabin is almost entirely achieved by the seats, but that feel is so reinforced by the firmer ride, the rasp of the exhaust and the quick reflexes of the engine and suspension that you can't help but think you're really in a posh rocket sled.
