British Jet for BOB?

Revelling in fantasy mate..Whittle and Von Ohain met in the US in 1978 and compared their respective designs and Whittle acknowledged that German concept was different than his...You should informed yourself a little better before posting nonsense..Yes co- inventors totally independent from each other. But germans were ahead in overall technology as in addition to von Ohain they also had brilliant engineers like Dr ANSELM FRANZ and Dr HERBERT WAGNER to whom we owe our high -bypass turbofan engines of today like RR Trent series , ring a bell?

You should maybe tone it down a bit. Yo don't just walk into a place and talk to people with that kind of tone.

Present yourself better. Do you understand?

Sure,no problem...

Well, yes and no. Yes, in that Wagner bench tested an axial flow compressor before the war, but no as in that it was intended to drive a prop, so was a torque producing unit; remember, the first incarnation, theoretical and practical of (aircraft mounted) axial flow engines were seen as a means of imporving propeller aircraft performance, not specifically as thrust producing units.

Also Rolls, who built the current Trent family of high bypass turbofans had its own 'mad scientist' in the form of Dr A.A. Griffith, who was proposing multi-stage axial flow compressor units with bypass sections (driving props) on paper before Whittle and Ohain built engines, albeit before he went to work for Rolls-Royce. Not only that, he also was partly responsible for engineering the first production bypass turbojet or called "turbofan" today, the RR Conway.

From Wikipedia:

"In 1926 he published a seminal paper, An Aerodynamic Theory of Turbine Design. He demonstrated that the woeful performance of existing turbines was due to a flaw in their design which meant the blades were "flying stalled", and proposed a modern airfoil shape for the blades that would dramatically improve their performance. The paper went on to describe an engine using an axial compressor and two-stage turbine, the first stage driving the compressor, the second a power-take-off shaft that would be used to power a propeller. This early design was a forerunner of the turboprop engine. As a result of the paper, the Aeronautical Research Committee supported a small-scale experiment with a single-stage axial compressor and single-stage axial turbine. Work was completed in 1928 with a working testbed design, and from this a series of designs was built to test various concepts."

Didn't von Ohain take some of his ideas from Whittle's original patent?

Good then carry on.

No he didn't .

Great thread everyone! With my interest in first generation jets of all nations, the information provided has been really interesting. And very true: Sir Frank Whittle deserves much greater recognition for his pioneering work. Sorry I don't have any further historical or tech knowledge to add, but the OP started off with asking about a jet for the Battle of Britian. Jet engines aside, does anyone have any info on a secret British jet fighter project that would have been combat ready by 1940? The earliest Jet fighter project was the Heinkel He 280, which started off on January 4th, 1939, and did not fly under pure jet power until March 30th 1941. Not intending to stick it to the Me 262 fans, but, this was weeks before the 262 even got off the ground ( barely, I might add) with a Junkers piston engine in the nose. Aside from the already operating nose wheel ( the 262 being a tail dragger), and the working ejection seat, it was a fairly conventional deign. The He S8 turbines fitted were as temperamental as any other prototype jet engine, and ultimately resulted in the project running out of time to prove itself. There have been a number of 'What ifs'" about this plane being combat ready by 1943, but it was never going to happen, and I can see the same drawbacks mirrored in a parallel British programme. Jets needed a few more years to iron the bugs out.
