"....and hopefully it will achieve Mach 7...the speed of sound."

Can't they get somebody knowledgeable to interject?

I heard the anchor say "mach 7...which would be 7 times the speed of sound."


Now what you heard might have been at a different time than what I heard, too.

I can tell you that when you are on the air on TV you have a producer talking to you in your ear while you are trying to talk to the camera.

That helps you to make mistakes in speaking.

anyone know a website that will broadcast the comm for this event?

 

[starvingcfi]

anyone else hear the reporter say they'll take the x-43a up to "95 hundred thousand feet?"

didn't know if i was just imagining that.

living with a hangover here, so anything's possible

And now the woman on Fox just mentioned how the B-52 was "escorting" the X-43.

Awesome

Thats where I got my name from.

Scramjet

 

[labbats]

I would have never guessed you got your name from Steve Ducey

From Aol news....

"The scramjet took over, using up about two pounds of gaseous hydrogen fuel before gliding. Applause rang out in the control center at Dryden Flight Research Center at Edwards."

Two pounds of fuel?? must be a typo, eh?

 

[Timebuilder]

Probably not.

An 11 second burn using two pounds of fuel is a rate of 654.55 (rounded off) pounds per hour.

Must have been some rate of acceleration to reach Mach 7 in 11 seconds from the 3,500 mph reached by the rocket motor.

 

[crowbar]

What is the speed of sound at the altitude that it went mach 7?

 

[bigD]

The Fox web site said the altitude was about 100,000 feet, so looking at my little chart here, it's 675.8 mph.

 

[A Squared]

Must have been some rate of acceleration to reach Mach 7 in 11 seconds from the 3,500 mph reached by the rocket motor.

That's about 4.6 g As a point of reference the space shuttle's engines are throttled to give a max acceleration of 3 g and an ejection seat gives you 12g-18g.

 

[bigD]

12-18g's?

Holy crap!

 

[crowbar]

A plane carries it to FL 350, than a rocket carries it up to FL 1000 and accelerates it to mach 5, and than a burn of something accelerates it another 2 mach.

What are they going to do know?

Looks like they need to have 3 types of engines on the missle to make it work, or launch them from fighters.

I want to see that mach 7 airliner.
