[SG] Nuclear-powered aircraft so large other aircraft can land on them in our future? - Page 17

post #161 of 250
Why is everyone talking about generating electricity with the reactor and then running propellers off an electric motor? There is such a the hung as a nuclear jet engine; air gets pulled in and compressed at the front and is pushed past the fuel (or, more likely, the coolant lines) , superheating the air, causing it to expand and produce thrust. The design of the jet engine isn't that complicated since it just replaces the fire with another heat source.

The challenge is the reactor. It has to be light enough to have a foot power to weight ratio, which is difficult given the shielding requirements. The other hurdle is a PR issue: the word 'nuclear' makes most people squeamish. It's a lot safer than people believe since reactors not melting down isn't sensational enough for the media.

No one really NEEDS to watch...I think it is just Navy policy. The jet's and the ship's computers will let every one know if everything is alright. Plus that guy waving his hand for a catapult to lauch a jet looks cool for recruitment videos. I wasn't a Navy guy though...just spent a lot of time on a aircreaft carrier and seen a few planes launch and talked with ship crew and pilots.

Though people on the plane could work fine too...just would need an oxygen mask and a good wind breaker coat. Might even be less dangerous than a boat since a life jacket will not always stop a person from drowning, but a paracute will ussually open. Plus, I think some one would be more likely to freeze in the water than up in the air unless they were out side at 30,000 feet without proper gear.

Should be enough force for a vertical take off...

Well of course, but that's obvious and ordinary (in this case), we all like to think out of the box. Don't forget you would still need an electric fan of some sort to generate the pressure to start the engine at takeoff. Said fan could also continue its operation in flight to aid in the generation of thrust and increase efficiency. In some ways it would act much like a modern turbofan jet engine, blameless and I discussed this..

It's really funny when you consider it deeply since it's not impossible, that is, if the energy was directed correctly and somehow made into useful thrust.

I think it would be far more practical to have a protected point of observation like the control tower at a modern airport. All you need is the three Rs, Runway, Radar, and Radio contact to make it work without a hitch every time. Ask any air traffic controller, my father was one.

basically anywhere in the southwest. LOLOL

This idea will never get past the cover of Popular Science.

I'd like to see the perfection of the SCRAMjet engine..before I'd even consider the thought of a nuclear drive. (and the doing away with lead shielding)

So many silly theories

If this were to ever happen it would most likely be setup in the upper atmosphere to act as a take-off point for low orbit space craft.

With enough wing span it would be able to partially glide indefinitely based on air currents and the curve of the earth. I highly doubt it would operate at passenger air-line altitudes.

First step towards commercial Space Flight!

^ thinking smart. in the pic it shows it in the upper atmosphere so it is more like to be for space flights.
