Anyone else keeping abreast of Bloundhound and their SA antics? https://www.youtube..../1050mph/videos

 

A waft of afterburner resulted in 334mph yesterday!

I wasn't but am now thanks !!

Been part of it from the beginning and thought it was a lost cause until the new takeover. 

 

Its a piece of machinery that has the potential to hit 1000 mph and Andy Green must have a big pair of balls to do that strapped to a jet engine and rocket. What a way to go.

..one assumes they took that into account when calculating the loading on the front wheels ?

461mph today, that's a fair old lick!

Currently my mate Jess is their ground controller (female voice on the other side of the comms), watching with anticipaction to see this break the sound barrier soon! The engine is barely on full throttle and it's so close! Amazing engineering

Isn't 500mph the aim of this year's trip?  Is that job done and go home?

I think they will be running more to work out some aero and particle movement. as they seem to be getting more wear in areas than they thought.

That's a proportionally huge tail fin. As a total amateur I'd have thought it just makes it more susceptible to side winds. Would steering it with the wheels be ineffective at those speeds or vectoring the rocket/jet a nonstarter? Why's it up top and not to the side(s) where it wouldn't increase the side profile? Interference by the nose aerodynamics, but the Typhoon's canards get to 1500mph?

How many points would that be on his licence ?

 

He'd never be given the option of a "speed awareness course"

Its all to with the aerodynamics , stability, yaw prevention

 

If you look at some of the civil airliners out there and look at the vertical stabilizer compared to the size of the Aircraft (B737 for example) you will see a similar thing going on.

 

A380 and 747 are massive as well although those particular aircraft will never get to Mach 1, that is unless things go seriously wrong.

 

And a cheeky cut and paste from another site

 

The vertical tail stabilizes the aircraft in the yaw axis. The fuselage is unstable, so a stabilizing fin must be added. Since the vertical has a much higher aspect ratio than the fuselage, it will stall first. Beyond the stall angle of sideslip, the vertical will not be able to overcome the still increasing instability of the fuselage.

That colour scheme must be holding it back a bit - everyone knows a stripe can add at least 10mph to an 80mph car, so by the time it's scaled up.....!
