Surely a small helicopter turbine is a better choice anyway? 665bhp easily, not may starting/warm up concerns like the F1 motor, runs on the same fuel as the EJ200, no issues with G / oiling etc. May even be able to drive the HTP pump directly from the power turbine (30krpm ish iirc?)
Probably smaller, needs less cooling, and about the same weight as the F1 motor too
I assume ~700hp is too much from the EJ200 accessory drive output?
Yes it is too much, there is literally no spare capacity on the accessory drive at all.Probably smaller, needs less cooling, and about the same weight as the F1 motor too

A small turbine was looked at, repackaging the car to accept at this stage would add too much to the project timescale.

so essentially, you are limited to another flavour of current or recent F1 engine. it could be either a very easy (hello renault, will you let us have last years F1 engine and we will make a marketing splash about it - "ok") or very difficult (5 or 6 phone calls later and everyone has said no, eek)
Or something lower revving, but with more torque, then we can gear up.Storer said:
I just happen to have an engine that produces 1500ftlbs of torque at just 1200rpm. 600hp and runs on petrol (ordinary unleaded so cheaper fuel than an F1).
Then you spoiled the idea by wanting a compact and light weight unit!
It weighs 650kgs and is 4ft long...............
The good thing is it was made in the UK...............about 58 years ago.

I've been following your build thread with interest. Can you imagine the step up box we'd need!!!Then you spoiled the idea by wanting a compact and light weight unit!

Been dying to blurt this out, but for obvious reasons it's been embargoed.

I am honoured that someone with your skills and demands on your time has had a look at my (very) simple little project!
Behave.I love the fact that there are still crazy people in sheds, doing stuff, just because they can. I'd love to see it in the flesh sometime.

On the rocket front. Does Andy have any control of the rocket once he has lit the touch paper? Can he "throttle" it or is it 'all or nothing'? You (he) must have some control, I assume, and can even shut it down if needed.
We can control the flow of HTP to the catalyst pack via a ball valve, therefore the power of the hybrid rocketEdited by IN51GHT on Friday 20th December 09:52

what does this mean for that chap with the moustache? Was it Daniel Jubb?
Is the inhouse development team no long needed at all?
All it really changes is the rocket, we still have to pump & distributed HTP, refill etc, so whilst the details of the system will change, the concept will remain very similar. Little, if anything will change within the Bloodhound team.Is the inhouse development team no long needed at all?

The Menard v8 in the caparo T1 produces 575bhp @ 10.5krpm on pump fuel.
Almost certainly got insufficient torque. Only has 290lb ft, so we'd probably stall it as we fed the pump in.I believe F1 lumps have in the region of 290lb/ft, but due to the reduction box that goes up at the pump to about 460lb/ft

Whilst I love the fact we Brit's have taken the last 3 land speed records and as yet the Americans can get close to them, I do wonder, if Bloodhound is successful and does take the record to beyond 1000mph, does that mark the end of the land speed record?
I hope not, whilst Bloodhound is no doubt bloody hard work some days, I'd be up for the challenge of a Mach 2 car once we are done.Megaflow said:
Getting to 1000mph is going to take a lot of very clever people, a very long time to achieve and I wonder if any faster is actually dooable. At some point we are just going to run out of land.

OK, interesting, potentially a bit of a PITA if you get a fluid leak, but i guess that is really pretty unlikely. What is the brake disc material/spec? Carbon/Carbon ?? (Assume you can't stop that hard with wheel brakes on a dry lake bed anyway due to a lack of friction)
Steel discs for high speed running, carbon for runway. Due to the higher friction offered by the rubber runway tyres carbon is required for runway testing.We did some spin testing on carbon discs from the Euro Fighter brake pack & we suffered failure at just above & just below 10,000rpm, so carbon discs were unsuitable for desert running.

Why is it L-shaped rather than the same shape as the sheet it came as? Is there a different material or thickness below?
Happy new year, by the way

There was another special event too.

Please tell me this was done the old fashioned way using an English wheel. And why a metal form rather than wood?
Is titanium difficult to use/shape or is it like very, very, very, expensive steel??
So many questions and so little time!!!

We couldn't make the skins from wood as it is not strong enough!!
