The Metrovick F2 design was pointing the way to future turbojet technology -
This pic probably taken at Glosters Bentham test facility -
The first british axial flow engine to fly was the Metrovick F2,early testing in the tail of a Lancaster and then 2 flight rated engines were fitted to Gloster Meteor DG204,this a/c crashed on 4th(14th ?) jan 1944 after only approx 3 hours of engine testing - unfortunately killing the pilot Sqn Ldr Davie AFC.
Unfortunately, on a test flight in Jan 1944,
one of the engine compressor rotors burst in mid-air, killing the pilot in the subsequent crash.
Though the cause was traced to metallurgical faults in the rotor forgings
