The design speed is 1050mph at the same location so if they're struggling to git 500mph runs in they've got a problem.
I was trying to work out how far down the run they would be at 500mph but then read your comment. 1050 mph ??? as in 17.5 miles per minute or 34 seconds at maximum velocity to clear the course. Add in terminal velocity to push through at circa 200mph even allowing for zero wind and the air doesn't get thinner like a rocket climbing, the sound barrier at circa 700mph, the fact the ground speed is not diluted like a jet fighter 200 feet off the ground, it might be a tad bumpy and a breath of wind is likely to be devastating to its stability, one does wonder if there has been a touch too much Michael Gove consumed on this project. It would be a staggering achievement. Go boys. Go !
So the current LSR is 760mph, set by Andy Green in a car that looks a lot wider and stable that this new car. Yet they want to increase the record by another 240mph?I was trying to work out how far down the run they would be at 500mph but then read your comment. 1050 mph ??? as in 17.5 miles per minute or 34 seconds at maximum velocity to clear the course.

As you say at that speed it's going to be a hell of a bumpy ride. I hope they do achieve it. Irrelevant as it is, but a great achievement for all those involved.
The car looks too narrow to me, and potentially unstable should it get bumpy at those speeds, that I fear it may be Andy Greens last drive.

You see that big fin on the back? That will provide plenty of stability at 500+MPH they are aiming forAs you say at that speed it's going to be a hell of a bumpy ride. I hope they do achieve it. Irrelevant as it is, but a great achievement for all those involved.

Have you watched the onboard videos from Thrust SSC? It was hugely unstable. Andy Green's ludicrous ability was all that kept it vaguely on track.

The new car has been designed using much more modern techniques to be stable within its performance envelope. It's the most strenuously designed LSR car ever, by a vast margin.
Onboard shot of the last time Green got the record - video gives the total distance travelled as fifteen miles. Amazing how calm he is, even when working the steering hard and giving a running commentary! Could watch this all day.

I forget we live in 2019, where not only humour is frowned upon, in case it offends someone, but also having an opinion is deemed offensive unless backed up by engineering mathematics or an in-depth thesis.
RumbleofThunder. I'll make a note of your name, and from now on any comment or opinion you make on any car within this forum, I'll expect an in-depth engineering report to back up your opinion.

What people are forgetting is that Thrust SSC was run in black rock desert Nevada which was deemed to small an area for this attempt.
They took years scouting a location big enough and then drafted in volunteers to help clear the site.
At its peak Thrust SSC went at 341 metres per second.

Recognise that I may open a can of worms here, but you really think he has "ludicrous ability"?It may be cynical, but surely he was initially drafted into speed records because it's great PR - he was a wing commander in the RAF.
And yes, he is used to high speed and you would like to think have better than average reaction time, but all the video footage shows of Thrust SSC is him gently sawing at the wheel. That's nothing compared to the control of snap oversteer that youngsters are reacting to in single seaters every race weekend.
Not knocking the guy, I just don't understand and happy to be enlightened. For me, the pat on the back is the willingness to be a guinea pig, and not really about ability.

If it was easy, anyone could do it!
My great uncle was chief engineer on the original thrust, driven by Richard Noble.
After the record run, I believe that calculations showed they were 15mph short of taking off.
These arrempts are on such tight computerised margins into unknown territory.
Good luck to a project that nearly came to a premature end.

Not a drama...yet. It did the same in Newquay when we tried to start it, but we hadn't shipped equipment quite as far. I was surprised they didn't try to start it over here before leaving.Gassing Station | General Gassing | Top of Page | What's New | My Stuff
