When are jets going to be replaced by the next generation technology?

Answer 1

i'd say within the next 10 to 15 years. F-22s, F-35s, and who knows UCAVs will be in service in our military by then. commercial airliners are mainly upgrading their aircraft like boeing for example. 747-8. But some new aircraft coming out soon is the 787, and the y1, y2 projects, intended to replace 727s and 757s.

Answer 2

If you mean the next generation of jets like the American military F-22s and F-35s (which are both the most advanced planes in the world) are already here. The F-22 went in service in 2005 and the F-35 will be in service in 2011. They feature full stealth capabilities, state of the art radar systems most advanced weapon systems in the world, world exceeding maneuverability, and state of the art all-around technology. They can also share information from satellites to each other or to bases to get the latest report in case they need to strike else where or to show the latest data to the military base operating with it.

The F-22 can exceed over 1,600 mpg without the use of afterburners (which is the first jet to have) and the F-35 can do any kind of roll like bombing, striking, defending, and can be carried at air force bases, aircraft carriers, and has a model that can hover off the ground like a helicopter and can take off and land like that.

The F-22 will replace the F-22 and F-16, while the F-35 will replace the F/A-18 Super Hornet and the F-111s.

Along with this generation of fighters, the military is also starting to produce unmanned aircraft. Some are already in service, and other are supposed to be in service no later than 2015. They are jets that can be operated without the need of a pilot. A person will control them at a base or aircraft carrier by joy stick and a screen, much like a video game. They can be used to spy on anything from a distance greater than 250 miles, bomb, will later be able to strike, and more. There are two in service right now. Their main jobs are to spy, but one is able to fire air-to-ground missiles.

If you mean when the next propulsion system will be available, not in another 50 or so years. Scientists are doing research and experiments on "anti-gravity" and "dark matter" which are supposedly allowed to propel a plane/rocket at speeds greater than 15,000 mph using negative force without the need of fossil fuels and a visible engine. The problem is that the future planes/rockets will have to be built very strong and sturdy to overcome the fricttion and drag. Also, the G forces will be tough for the passengers or crew that operate the plane/rocket.

Answer 3

Just as soon as you get off your behind and invent it.

Right now there's no new technology which is seriously competing to power current or future aircraft designs with the sort of speed and efficiency we have already. There are deltas in performance, little gains here and there, reductions in parts counts, cores that can run hotter and produce more power. But there's not a new type of engine waiting in the wings to power a lifting body airliner of the future.

What will the future bring? Trains and boats. If the US had coast to coast high speed rail lines they could move people much more efficiently, it would take a bit longer, ten or twelve hours in a comfortable seat instead of six as a sardine.

The hydrogen economy is a myth, there's no efficient way to obtain and store hydrogen in the quantities that would be needed to power a 747 class vehicle. It's too inefficient (half the available energy is lost in obtaining and compressing the hydrogen) to compete. We don't have enough petrochemicals to make the fertilizer to grow the corn to make the alcohol that would replace the gas that we could have made from the petrochemicals instead of fertilizer...

No rosy future. We are likely to be making gas from coal before you see a major change in engine technology.

Jets have ruled since the 1940s and there's no sign of their imminent demise.

The English Electric Lightning could suprcruise back in the early sixties. My friend Terry Adcock flew one down the North Sea at over 80,000 feet and M3.0 before they added the belly tank and strakes, but their performance was secret (officially better than M2.5 and better than 65,000 feet) until they retired from service in the 1990s. Concorde was supercruising back in the 1970s. Supercruise means cruising supersonic without reheat. It's no use Johnny Come Lately smart mouth marketeers coming along nearly 40 years later and trying to redefine the terminology so that they can seem something other than very very late to the efficient supersonic cruise party. Heh, that's going to earn me a few thumbs down but you people know nothing outside of the US version of the world.

Answer 4

Jets still are the next generation technology... they are making major improvements still to these powerplants... I dont see them ever doing away with the jet engine... I can see them making it run on something other than the Jet A that we know today...

Answer 5

which "next generation" technology are you referring to? the next jet engine technology is already here in a number of engines. scram jets have yet to be perfected to the point where they are ready for commercial use. as for star trek technology, that is still off in the distance at least 50 years if not more.

Answer 6

Not for a long time. We'll get a good idea when this will happen when they stop using the 727's and the A320's.

Answer 7

the beoing 787, airbus a380, and airbus a350

the beoing 727 is about 35 years old and is still being used today so that means the ones we use now will last for a while

Answer 8

All I ever wanted was a crystal ball. Maybe just one copy of tomorrows wall street journal.
