Top Secret Aircraft?

Aurora = an advanced hybrid of turbojet, ramjet, and rocket at least as it's theorized.

And no....I don't believe aurora is dead. We still need high speed reconnaissance aircraft.......not enuf satellites in the sky to se everything we need to according to experts

I'm quite confident that Aurora is dead. That does not mean that they are not using the lessons learned on something even more exciting.

Cool thread keep it coming guys! I used aurora's in C&C Generals I just read a bit on them and I guess the whole thing is very hush hush but rumors are that it can hit mach 6 (almost 4000 miles/hour). Mach 5.4 is the "hypersonic" point (can't remember what defines it as such).

I think that "Hypersonic" has been defined as flight in excess of Mach 5. I don't think there's more to it than that.

Found the link I was reading

The definition of hypersonic isn't as clearly defined as supersonic, but aerodynamicists consider that the hypersonic realm starts when the air in front of the vehicle's leading edges "stagnates": a band of air is trapped, unable to flow around the vehicle, and reaches extremely high pressures and temperatures. The edge of the hypersonic regime lies at a speed of roughly one mile per second - 3,600mph or Mach 5.4.

I stand corrected.

Well to your defense it isn't as clearly defined by that link's own admission

I know the XB-70 had severe stability problems.

I just love the look of it.....
plus there's nothing like standing at the back of it and seeing 6 friggin engines.

On top of that...the study it was used in was absolutely cool......studied how to use the shock wave created with going supersonic....

When i think of all the things we did in the friggin 50's and 60's to study supersonic flight, it blows my mind.

X-15---space flight pioneer
Lifting Bodies---pioneer to the Space Shuttle's design

Wing studies---hell in the 70's they even had an aircraft (don't remmber the name) that the wings were angled frontwards on

And then there's the ramjet/scramjet tests. I saw a discovery channel special about a test with ram-jets in the 60s where they just tested the functionality of it on a F-105. It was fitted on the end of the wings of the aircraft, and just tested for functionality. They didnt' throttle it up b/c it would have torn the wings off (so discovery said)

What is the fighter with the directional jets called? (No, not harrier) I saw it on a program a while back, absolutely rules!!!!

x29 i think. the shuttle isn't a lifting body, though.

I thought that was a mig? I could be wrong, though I was fairly sure it was a russian aircraft.

Do you mean directional thrust a la VSTOL?

or

Thrust vectoring a la Su 27/F22?

I think the F-117 mad its debut in 1986 (Not sure of the year, but close) when one crashed near Bakersfield, CA, depending on what you consider a debut... I remember it receiving quite a bit of press coverage at the time....

 

[crisp82]

I think the vectorable thrust one. But I think the F22 as well. Help

It can basically fly straight up, move the thrusts, and move into a freefall constant nose over tail maneouver. Basically does stuff no aircraft in current service (that we know off) can do

I think I know the aircraft to which you are referring (it can virtually hover?) as I have seen something Russian that sounds much like this. I cannot remeber its name though!!!!

almost all new russian aircraft can do that..their planes, in terms of aeronautics, are far superior to US planes, but in terms of electronics warfare, US planes are superior....russian planes can fly higher, faster, and their Su-27?32? or something? can outmanuever the f-16 easily just because of the 3-D thrustvectoring they have.....the only plane in the US inventory w/ thrust vectoring, the F-22 (probably not going to be in action in this war) has only 2D thrust vectoring....they tested the thrustvectoring on an F-16 and on another plane....but they never really have a plane w/ it...

Is bugging me now. Yep, hover sounds about right.

3D thrust vertoring sounds familiar. Was Russian.......

As the US military gets more and more automated it will be really increase the gap between itself and other militaries that aren't on the cutting edge of technology. Who the hell wants to put their life on a line to take out an unmanned plane worth relatively little?

In 20 years the US will have a fleet of them piloted by the best Star Wars video game pilots taken from competitions. They'll give these people money to take their video gaming skills and apply them into a real combat situation controlling planes thousands of miles away.

OK maybe I'm talking sh*t now.

Thats what Americas Army was all about! You see, there will be a ranking system that is truly based on skill and the top players will command the troops! Think about, you get drafted, you play some AA! Where do I sign up?

 

[Lounatik]

the F-22 (probably not going to be in action in this war) has only 2D thrust vectoring....they tested the thrustvectoring on an F-16 and on another plane....but they never really have a plane w/ it...

I was watching Nova on PBS a few weeks ago. They had the story of Lockheed and Boeing going at it for the ATF-F22 (which Lockheed won) and the reason it won was because of the ability to land, take off,and hover in about 30 seconds.So I guess that means it has 3d thrust vectoring?Correct me if I am wrong. Oh, Lockheed also has a wild shaft drive for the downward turbine that eliminated the hot gas intake/stalling problems that seem to plague VSTOL planes. Some wild stuff.

It WAS Supersonic until the Congress cut the budget and had the engines and nacelles 'De-Tuned' which
disabled the capability to reach supersonic speeds.

your link says that the B1 is supersonic.. and so has everything else that i have seen about it - including the boeing webpage

 

[CaptnKirk]

When I was on that project, the mods were made to the intakes and compressors that limited the capability to .95 Mach.
This was on A/C # 4 & up. Ships 1, 2, & 3 did have the original articulating vanes for flight test.
Publicity still publishes what they want to present. The cost was 1.4 Million in 1976 $$ when the change was made.
Ship # 2 was lost in a crash, and the ejection platform malfunctioned, but the crew did get separation.
Test pilot was lost in the accident.

Oh - By the way how many HOURS do you think the entire fleet of Operational F-15's have logged in supersonic flight?
The answer is less than 1 total hour for the entire fleet of all (Except test programs) F-15's in service.
Just because they CAN do it dosen't mean that they do actually do it.

Gruman X-29 had forward swept wings - Aerodynamic nightmare - Resonate Tip Distortion.

SU-27 Flanker is the one that can do the 'Cobra' manuver.
