Specification X.197T

[Retrofit]

Specification X.197T was issued in March 1959 to cover the design and construction of an aircraft to investigate the low-speed characteristics of the slender delta wing, in collaboration with the RAE.

Bristol submitted its Type 215. Designs were also tendered by Fairey, Miles and Handley-Page.
The Handley-Page proposal was selected and, in final, resulted in the HP.115 (under the revised specification ER.197D).


Is there more information available on those 4 initial X.197T proposals?

Thanks in advance

Robin.

Jemiba, Robunos,
Thanks a lot for information.
If the project presented in Aeroplane Monthly seems to be at the origin of the HP-115, the Supermarine Type 573 is a discovery for me (connection with Fairey or Bristol?)
Thanks again

Best regards,

As my dear Jemiba suggested before,it was a Slingsby design,later developed into HP-115.

We did a piece on X.197 in Aeromilitaria a few years ago. I can check when I get home.
