My Royal Aircraft Factory designation list likely duplicates what AM has already produced (alas, I can't open doc files). Anyway, an html version will be more searchable and, with luck, there will be some additions ...

Royal Aircraft Factory Designations
The mandate of the Royal Aircraft Factory originally restricted its activities to the building (or rebuilding) of experimental designs. Initial RAF designations combined an airframe layout type with 'Experimental'.
The layout types were named after individual aircraft designers -- S.E. (Santos Experimental after Alberto Santos-Dumont) for canards, B.E. (Bleriot Experimental after Louis Blériot) for tractor propeller designs, and F.E. (Farman Experimental after Henri Farman) for pusher propeller types.
By 1913/1914 the layout type designations were abandoned in favour of role designators. The F.E. and S.E. designations were retained but with new meanings.
Role letter combinations were: A.E. (Armed Experimental), C.E. (Coastal Experimental), F.E. (Fighting Experimental), N.E. (Night-flying Experimental), R.E. (Reconnaissance Experimental, S.E. (Scout Experimental).
An exception was the in-production B.E. series (which remained Blériot Experimentals). An anomoly was the B.S. series which combining the Blériot name with the Scout role. A.T. (Air Target) fits the role letter series ... except that the name was a counter-espionage cover designation.
Harder to explain are the unbuilt T.E. series. The original T.E. (Tatin Experimental) was named after the tail pusher-prop configuration of Victor Tatin's 1911 Aero-Torpille design). But the later T.E.1 concept was an enlarger S.E.5a fighter. In the latter case, the T.E. may have stood for 'Tractor Experimental' -- an attempt at rationalizing the RAF designation system?
For sub-types, suffix letters were applied. Older sources tend to render these suffixes as lower-case letters, later sources as capitals. I have stuck to lower-case. Royal Aircraft Factory engines were given type numbers after R.A.F. Here I have written engine types as 'RAF' as a space saver.
NB: For airships and balloon designations, see: Kites, Birds & Stuff: The Aviation Archive of the Royal Aircraft Factory + Inflatables by P.D. Stemp.

Amazing a prefect work my dears Apophenia and AM,and I can add;
B.E.11 someone suggested that,it was anther variant of B.E.2 .
Hurricane was single seat mid-wing ultra-light monoplane of 1923,powered by one
600 cc engine.
Zephyr was single seat twin boom ultra-light biplane,powered by one 500 cc engine.
Scarab was single seat parasol-wing light monoplane,powered by one 32 hp
Bristol Cherub III engine.
Sirocco was single seat ultra-light monoplane,powered by one 32 hp Bristol Cherub III
engine,never completed.
Rafwire experimental aircraft,no more details.

Thanks folks!
Hesham: Thanks for the B.E.11 connection. RAFwires (or rafwire) were streamlined, high-tensile bracing wires (as used on the S.E.5a).
Hurricane, Zephyr, and Scarab were designed and built the Royal Aircraft Establishment's Aero Club -- the R.A.F. being renamed R.A.E. in 1918. Below is a separate list of RAE design names.
