Er, that's Boscombe Down, and it was probably R7700, which went there for gunnery trials.

Thank you for the corrections Edgar. I guess I'm moving at the speed of stupid mistakes again.

 

Thanks again for keeping an eye on me. I am pushing time a little because I hope to finish the Typhoon and Tempest A.S.A.P. with the idea of fine tuning as I go. Next up I am hoping to post the Spitfire. I might post the skeletal information I have on the chronology of the Spitfire hoping that others can fill in correct engine boost levels and deployment of each model. The Spitfire will definitely take a great deal of time.

 

Jeff

Here is a link to a 1941 Air Fighting Development Unit Tactical Trial: http://www.wwiiaircr...ical_Trials.pdf

- which compares the Typhoon I performance in the fighter role with the then current  Spitfire VB 

 

The Typhoon on test made 368 mph at sea-level, 388 mph at 5,000 ft & 412mph  at 20,000 ft, bettering 380 mph over a 25,000 ft band.

 

Is there a 1941 dated  Gov't Service Unit ( not maker's figures) test of a combat spec aircraft - that beats the Typhoon therein shown?
