the rocket bit it just for extra thrust, like an afterburner...
but a prolonged kind

I'd love to experience an afterburner :lol:

the difference between fighter jet and passenger plane is that a fighter jet cannot "cruise" like a passenger plane in case of engine failure.

how do you mean, in case of failure and not cruise? what
please do explain, but dont get me wrong, i can understand something if its along the lines of, like...particular jet engine in high state of tune, it cant spin slower or the fans/turbine blade angles/shape design means it cant gobble 'less air' its made to chomp MASSES of air in BIG glups or such wish, am i getting of the track or far off or what?

a fighter jet is designed to fly at supersonic (or close) speed and make a quick turns with high g-force. there's absolutely no reason for a fighter jet to "glide" or fly at the speed of jumbo jet since it's a war machine.

for that specification needs (supersonic speed, high maneuverability, carrying bombs, quick take-off, afterburner, etc) - the design doesn't allow it to glide like a regular plane. in case of engine failure, it will just simply fall straight to earth. war planes with cutting edge technology like F-22, Stealth Fighter, Stealth Bomber, etc, etc are actually aerodynamically unstable. since it has powerful turbine jets, it has hundreds, if not thousands, of computer chips/sensors to correct itself every second... with that - it's able to do something impossible and unbelievable that seems to defy conventional physics of "natural" flying.

the more unstable a fighter jet is, the more maneuverable it is. if you take out turbine jet from F-22 and put on the most powerful turboprop... it won't even be able to take off.

so what happens if you replace turboprops with turbine engines on regular plane? you get 747 and cargo plane - an ability to transport a massive amount of stuff from point A to point B in the most efficient manner.
 
ah, so the wings is made for turnings and cuts not glide...
that si unlike 747s or similar are gliders with flaps to make turns to blend with a more docile turboprops jets...
i see...and its also means, ....more 'practical as in if an event of engine failure a passenger jet *might* glide to earth than fall straight down...

yup! in terms of aerodynamic design and efficiency, a new Dreamliner is actually very similar to one of the biggest birds - albatross. Albatross can literally glide for thousands of miles without flapping. it's unbelievable.

a "natural flying"... this one aka glider or sailplane would be more accurate :lol: because it has no engine. it's powered by heat emanating from earth which is how large birds like condors and albatross can fly over long distance with great efficiency -

yup. that's what happened to US Airways Flight 1549. It glided back to earth (err water) when both of its engines failed.

Fighter Jet or Stealth Bomber won't be able to do that. that's why they invented ejection seat lol.
 
ive learned something... pity they cant glide, i mean it would be good if they had a change to glide OFF and OUT of the enemie's aerospace...
hmm

Been there and done that in California. :) Very smooth floating in the air with no engine. It was towed by a double propellor plane to the height where it was released.
 
I just found out that fighter jets CAN glide, just that they don't drop like rock and since they can glide with very limited power to stay gliding, meaning the pilot must find nearest runaway FAST! I mean very fast, and if it is not possible, then it will glide to the point it crashes. While these aerodynamic friendly planes can glide much farther and have more time to search nearest runaway.

But your right about performance, it requires engine running constantly to maintain in flight.

not really. I think you read it wrong.
 
Well, I read and said most fighter jets has limited gliding abilities. In other words, older fighter jet has better gliding abilities than newer ones.

I haven't found information about stealth fighter. I remember that it has almost zero gliding abilities without engine.

Stealth fighter was nickname as "Hopeless" because of design making it almost impossible to glide or fly but they figured out.

that's what i thoght too, a more modern fighting aircraft aren't 'planes' but rockets with flaps (but using jets instend of rockets because they want to be more fuel efficient by using available oxygen/hydrogen in the atmosphere)...it is the flaps that makes the plane 'fly' as in turns, change directions, rolls, climb and drop, not the 'planes' as in with a gliding/or straight lift factor...

yeah

so key word here is Flaps technology and jets as 'atmospheric 'rockets'...theres aren't normal jets.....
its like comparing car engines in between internal recalpirating pistoned engines and wankel rotarys
completely different workings and "temperments" but bot rely on similar fuels for these to be functional...er well different chemical composition of jet fuel /AV gas i dunno i havent read ANYthing prior this or yesterdays post, i just think with my own head...(so im a thinker as you see, not just a reader)
 
Not just that, but they are attempt to keep the jet engine as cool as much possible. The hotter it gets, the easier it gets detected by radar.

Stealth fighter don't go over 600 MPH because if they go over that speed, the ass gets red hot and will show up on radar.

Nice design. How can it takeoff without engine? Like Albatross flapping to takeout. I understand it can landing and flying without engine necessarily.
 
My dad rode on that one. It is done by tandem. To start the fun, that glider needs to hitch to another plane that have engine to make the lift. Its like truck hauling trailer. Once in right altitude, they get disconnect so that glider can go gliding. Just like as if trailer got disconnected from truck, trailer won't stop the motion right away, right? The only difference is that trailer can't navigate and will crash.

Here is video that would help you understand how to start the glider

ah...didnt think of that...hmm ok , thats interesting!....like 'how' lol now, only if we can borrow their jet's technology to have the best intercoolers in our cars.....
lol
