Bloodhound diary: Flaming hot Bloodhound diary: Flaming hot

RAF fighter pilot Andy Green intends to get behind the wheel of a car that is capable of reaching 1,000mph (1,610km/h). Powered by a rocket bolted to a Eurofighter-Typhoon jet engine, the Bloodhound car will mount an assault on the land speed record.RAF fighter pilot Andy Green intends to get behind the wheel of a car that is capable of reaching 1,000mph (1,610km/h).

We're close to finishing off the final shaping at the back end of the car and, after a lot of research and debate, we've also settled on the lateral stability requirement for the car.We're close to finishing off the final shaping at the back end of the car and, after a lot of research and debate, we've also settled on the lateral stability requirement for the car.
It needs to resist a 0.8G lateral load, which will give us a rear wheel track that is narrow enough to do 1,000 mph, but plenty wide enough to make sure the car doesn't roll over.It needs to resist a 0.8G lateral load, which will give us a rear wheel track that is narrow enough to do 1,000 mph, but plenty wide enough to make sure the car doesn't roll over.

Of course, we already have the EJ200 jet engine that will power the car, and we had the first set of wheel bearings delivered last year, but this is different - this is a piece designed and made specifically for Bloodhound.Of course, we already have the EJ200 jet engine that will power the car, and we had the first set of wheel bearings delivered last year, but this is different - this is a piece designed and made specifically for Bloodhound.
It's the pump impeller, which will force a tonne of hydrogen peroxide (HTP) into the rocket in just 20 seconds.It's the pump impeller, which will force a tonne of hydrogen peroxide (HTP) into the rocket in just 20 seconds.
It seems hard to believe that it will take over 600HP to turn this little paddle wheel (even spinning at over 10,000RPM) - we need our 800HP V12 MCT engine in the car just to turn it!It seems hard to believe that it will take over 600HP to turn this little paddle wheel (even spinning at over 10,000RPM) - we need our 800HP V12 MCT engine in the car just to turn it!
I was down at the Bloodhound Technology Centre in Bristol last week, discussing how we will transport, service and refuel Bloodhound SSC once it's ready to go.I was down at the Bloodhound Technology Centre in Bristol last week, discussing how we will transport, service and refuel Bloodhound SSC once it's ready to go.
We also made some key decisions on systems, including the hydraulics, electrics, jet and rocket starting/shutdown, etc.We also made some key decisions on systems, including the hydraulics, electrics, jet and rocket starting/shutdown, etc.
Now I can get on with designing the cockpit in more detail - I should have a picture next month for you.Now I can get on with designing the cockpit in more detail - I should have a picture next month for you.
Hywel and Andy mould the perfect steering wheelHywel and Andy mould the perfect steering wheel
As part of the cockpit design, Hywel (one of our two year-in-industry students) has been given the task of designing the steering wheel for the car. I need something easier to use than, say, an F1 car steering wheel, but with more controls than an aircraft steering yolk.

Hywel is starting from scratch, taking a mould of my gloved hands to make sure that the wheel is a perfect fit for me. After a little trial and error (and without getting too much clay on his computer) we've now got a shape to scan and manufacture.Hywel is starting from scratch, taking a mould of my gloved hands to make sure that the wheel is a perfect fit for me.

Hywel's loving the best year-in-industry job he could possibly imagine - and I can't wait to see the fastest steering wheel in the world.Hywel's loving the best year-in-industry job he could possibly imagine - and I can't wait to see the fastest steering wheel in the world.

Another research programme that we started last year was to design a really good high-protection driver's suit.Another research programme that we started last year was to design a really good high-protection driver's suit.
Normal race suits only offer short-duration protection from fire (the cars are only going slowly, so they can quickly stop and jump out) and have never been tested against highly corrosive HTP (because they don't have huge rockets attached!).Normal race suits only offer short-duration protection from fire (the cars are only going slowly, so they can quickly stop and jump out) and have never been tested against highly corrosive HTP (because they don't have huge rockets attached!).
Last year, Leeds University did some testing for us to show that a range of fire-resistant materials can also withstand HTP, so now we're looking for the most flame- and heat-resistant material.Last year, Leeds University did some testing for us to show that a range of fire-resistant materials can also withstand HTP, so now we're looking for the most flame- and heat-resistant material.
A company called Lamination Technologies has developed an incredible new flame-proof fabric and has been doing some "Pyroman" testing for us, which is showing great results.A company called Lamination Technologies has developed an incredible new flame-proof fabric and has been doing some "Pyroman" testing for us, which is showing great results.
