Re: EmDrive
zanimljivo, al koji ce im to kurac, naime problem je u utrosku energije, bez obzira sto u svemiru nema gravitacijskog i inog otpora ipak dovesti neki objekt brod u stanje brzine recimo pola brzine svjetla treba ogromna energija al kvaka je da isto toliku energiju trebas za kocenje, jbga, u svemiru hladno pa gume proklizavaju, znaci trebaju dva motora, jedan potisni i drugi zaustavni osim ako bi brod bio konstruiran da okrene motor na drugu stranu, sto se tice putovanja svemirom ono ce uvijek ostat problem dok se ne svlada koristenje gravitacione sile, sve ostalo je bzvezni startrek il neki drugi sf umisljaj, postoji i mogucnost putovanja koristenjem 5 dimenzije al to je za sad pretezak zadatak za umislit a kamoli napravit neku tehnicku alatku za eksploatiranje

[size=47]NASA's Innovative Ion Space Thruster Sets Endurance World Record[/size]
By Nola Taylor Redd, SPACE.com contributor | September 24, 2013 02:00pm ET
The next generation of ion engines have a fuel efficiency 10 to 12 times greater than traditional chemical thrusters.

A five-year test of NASA's latest ion drive for future spacecraft has set a new world record for the longest single space enginetest.
The space agency's Evolutionary Xenon Thruster (NEXT) project completed a continuous test the ion engine for more than 48,000 hours — over five and a half years — longer than any other space propulsion system ever tested. With low fuel weight and long-running efficiency, ion engines have become strong contenders for deep space missions.
Spacecraft traveling through miles of space require energy to keep moving. Ion propulsion engines can help to minimize the bulkiness of fuel, allowing for increased scientific exploration in smaller packages. Over the course of nearly six years, NEXT consumed only 1,900 pounds (860 kilograms) of fuel, compared to the 22,000 pounds (10,000 kg) a conventional rocket would burn to create the same momentum. [Watch a video of NASA's Evolutionary Xenon Thruster in action]
[/size]
Part of a class of solar electric propulsion (SEP) engines, NEXT bombards xenon with electrons, ionizing it. The ionized propellant is then focused out the back of the engine, creating a stream of ion jets known as an ion beam. The movement creates the thrust that moves the craft.
Ion engines win out over traditional engines much like the tortoise defeated the hare. Though it takes more time to speed up, it is able to run longer than its competition. Charged particles from NEXT reached speeds of up to 90,000 miles per hour (144,841 km/h), making it ideal for deep space missions in particular.
"SEP uses electricity, generated by solar panels, to power an electric thruster to propel spacecraft," principle investigator Michael Patterson of NASA's Glenn Research Center said in a statement. "Because it reduces the amount of propellant needed for a given mission, it greatly reduces the weight of the vehicle."
Less weight means less traditional propellant required to launch the craft into space — or more room for science. Ion engines on NASA's Dawn mission, which traveled to the asteroid Vesta and is now headed toward the dwarf planet Ceres, enabled its team to include more scientific equipment than they would have managed on a traditionally-powered craft.
Once the staple of science fiction, ion propulsion engines have made a slow influx in military, commercial, and civilian space programs. An ion engine propelled NASA's Deep Space 1 mission, launched in October 1998, demonstrating the engine's long duration.
"The bottom line in space is to maximize the payload we deliver including potential missions in support of human operations and scientific payload," Patterson said. "We don't want to spend all our resources pushing propellant around. NEXT can fly huge payloads deep into space with super fuel efficiency."[/size]

Re: EmDrive
Da,Nasa je vec uspjesno izvrsila bar jedan eksperiment sa tim,dok Roskosmos npr se fokusirao na rakete na nuklearni pogon,i jedno i drugo bi bilo bolje od sadasnjih hemijskih raketa,ili space lift,mozda u nekoj doglednoj buducnosti.

Re: EmDrive
prije koju godinu sam bas lijepio nes o tim Ionskim motorima...bed je da treba duuuuuugo da ubrzavaju,naime izlazna masa fotona je goli qrc..Winter is coming wrote:Da,Nasa je vec uspjesno izvrsila bar jedan eksperiment sa tim,dok Roskosmos npr se fokusirao na rakete na nuklearni pogon,i jedno i drugo bi bilo bolje od sadasnjih hemijskih raketa,ili space lift,mozda u nekoj doglednoj buducnosti.
pa bi samo ubrzavanje jako dugo trajalo..
hahahahaha,Medo vid sto iskopa...

slijedeci korak bi trebalo biti rakete na nuklearni pogon,sadasnje kemijske rakete su spore i neadekvatne,nuklearni pogon bi omogucio putovanja dublje i dalje u svemir,vecu brzinu i nosenje 3 puta vise korisnog tereta

Re: EmDrive
hm da,treba im dugo ali oni bi i bili namjenjeni za putovanja na duge staze,a mana bi im bila isto dugo usporavanje ali to su samo poceci,prvi djecji koraci,onaj Ruski sistem mi isto izgleda o.k,ako i jedni i drugi razviju razlicite tehnologije,mozda bi u buducnosti bilo moguce napraviti i kombinaciju jednog i drugog sistema,to bi bio neki hibridni sistem,zasto ne.
