Re: Technical Talk

The whole fuel system with the exception of the AFRC is original. The AFRC came from a crashed Gnat and was lying in the cellar at Shaftmoor Lane. K7's fuel system didn't have one. It had a primitive anti-surge control, one of only two ever made, and described in its own test report as a 'lash up'.

Re: Technical Talk

Because it's the original one that pumped fuel on the 4th January 1967

Re: Technical Talk

Looking as the Bristol Siddeley Orpheus 10001 ECU Fuel System Diagram (as you do....), the Servo drilling/orifice is visible just to the right of the HM Governor Diaphragm on the pump (where the Yellow & Orange colors meet). Now if we had that type of pump we'd be OK. Ours predates the HM governor ...

Re: Technical Talk

A way to 'de-inhibit' is to do some wet motors (or cranks) - like a start, so fuel on, but with no ignition. BUT this assumes your drains work well...! ANd you need a least 1 dry motor (or crank) - so just starter only - to 'blow' any fuel left in the engine out of the back. If in doubt, do 2 or mo...

Re: Technical Talk

First engine start since 2016 tonight and, like everything else, full of legacy-headaches from 1966. Despite our best care and efforts we had a rather hot-start with much fire requiring extra effort to blow the fire out, rein in the JPT then shut down and dry-crank to get the heat out of the engine....

Re: Pic of the Day

Is there a pic of the boat hanging from the ceiling??? Quick pic from my phone until Mike sorts out an arty one. Boat Hanging From Ceiling.jpg The front was stropped at the outer roots of the main spar where it meets the sponsons and the rear was stropped through the Orph' engine mounts. It wasn't ...

Re: Pic of the Day

A further idea for the Starter would be to just have a simple orifice, to restrict flow & drop the pressure, in the Starter inlet (or before it) - instead of the plate - the idea being to drop the pressure to around 40psi, at the inlet to the Starter turbine. The problem there is that all the deliv...

Re: Pic of the Day

The part l really didn't enjoy was hanging the boat from the ceiling to get the cradle underneath. Yikes, that was scary!

Re: Pic of the Day

The 400 cycles limit makes some sense, as the system came from an Experimental Aircraft, which probably wasn't expected to do very much. For K7 as rebuilt in 66, it also made sense, being enough for one more record - and nothing more. For K7 now, I can see its a concern - and the uncertain capacity...
