A question for Barrington Bond - the five Hawker/HS projects you shared since 2011 (P.1132, P.1152, the twin Pegasus strike aircraft and two unnumbered HS naval designs); what is the source for the drawings?

The various BAC and HS attempts to replace the
Hunter FGA and Sea Vixen with ambitious VG and
VSTOL designs did not end with P1154. Between 1958 and
1968 a huge raft of designs were prepared, and carried on
into the 70s as Harrier and Jaguar replacements.
These paper projects deserve a book of their own.

From the September 1987 Hatfield Future Projects Newsletter:

1976-77 BAe/HSA Hatfield entries for the US Navy Type A V/STOL competition. Two designs are shown, one a twin boom ducted fan design, the other with three vectored thrust engines and three lift fans.

"This page devoted to our work of a decade ago for a submission to meet a US Navy requirement for a V/STOL aircraft, is published to serve as a small tribute to Charles Bradbury*. Who, in 1977 when this HSA/BAe submission being entered with other US competition for the Type A Aircraft capable of carrier borne operation, was responsible for the overall design of one of four types proposed. Known as Aircraft Configuration No 1, Charles designed this to incorporate three lift/cruise engine and three lift fans. In 1976 the US Navy confirmed the need for a V/STOL Type A, with missionised versions suitable for ASW, AEW Marine Assault, VOD, Tanker and SAR roles, in order to increase effectiveness of ship based airpower. VTOL would allow dispersal to small ships, with STO would permit increased capability from larger ships. BAe/HSA was one of six companies who submitted some eight volumes comprising the total submission in answer to US Navy requirements. One of the principal projects included in this submission was an advanced ducted fan, twin boom aircraft, for which Charles displaying his talents as an artist produced this lively impression in oils of the aircraft, for use within the promotional and presentation material."

Joint Study - Fixed wing Bi-Service aircraft.Fixed high aspect ratio wing with twin deflected thrust main engines plus additional lift boost engines.
Is it just me or do you feel like slapping the designers of HSA and telling then to loose the ______ing V in V/STOL ?
Just like the P1152 this would be a sensible design but for all the V/STOL elements.

Some more gems from the Hatfield stash...

First image is the HS133 with 18 RB202 lift engines. Second image shows a more generic design in a proposed 'VTOL Port' by London based engineering consultancy Brian Colquhoun and Partners. Third image is again more generic with features from the 133 and 141...

From the Hatfield Future Projects Newsletters No.24, April 1988

1969: HS138/145 VTOL Fan Lift W.S.R (Wide Speed Range) projects...

"The HS138 is an aircraft designed to the draft specification for a "Wide Speed Range Aircraft". It is intended to combine the high speed attack capabilities of the high speed strike aircraft with the low speed search and strike potential of the battlefield helicopter. The HS145 is an 8-seat executive aircraft using the same lift fan and outer wing geometry as the HS138. They each employ four RB.202-25 lift fans at the same rating as used in the HS141 VTOL airliner (i.e. 10,900 lb. SLST)and two propulsion engines with full thrust deflection. One means of achieving the desired degree of commonality is shown by the configuration represented

The specified mission with a crew of two and a 2000 lb weapon load (Carried out and back) is over a radius of 115 nm. at sea level under ISA 15°C temperature conditions at 575 mph EAS. At mid point, a search at a speed not exceeding 60 mph EAS is carried out for 15 minutes followed by 5 minutes at maximum speed."

I wonder if that project was one that Dave Williams worked on when he was at Hatfield. Its got an Addax-S vibe to it...

Unfortunately apart from people retiring the leaflets are very short on details of the designers and engineers...

Another V/STOL project from Hatfield... the HS139 from 1967. The article in the newsletter is much lighter on detail than some of the others, however it hints at collaboration with Dornier as mentioned in the Flight Article from post #6. The engine details I suspect refer to the prototypes, with the first two airframes being CTOL and the Alison lift engines being installed from airframe three onwards.
