Avro 707

The development of the Vulcan required a lot of concept testing before the full size jets were built.  Avro built a series of smaller scale delta winged jets to work out some of the issues under the name Avro 707.  One of these lives at Old Sarum in the Boscombe Down Aviation Collection.  It is painted a bright orange color and, while tucked in a dark hangar, it still looks striking.  It would be great to get some elevation to show off the delta planform of the jet but still happy to have managed to see it.  I was rather close to it so needed to shoot a variety of shots to stitch together afterwards which only worked so well.

Rafale A Demonstrator

Scan 2-1502.jpgThe Dassault Rafale is a fantastic looking aircraft. Gradually being built in reasonable numbers, it has broken into the export market and has customers in Egypt and Qatar and probably India although exports to India are always hard to pin down! The French air force and navy will no longer be the sole operators. The Rafale B is a two seat version and the C is the Air Force’s single seat version. However, there was the Rafale A. One of them was built in the mid 1980s as a demonstrator. It looks almost identical to the production version but was actually slightly larger. Painted in Dassault’s house colors, it made a number of air show appearances. At the time, it was competing for attention with BAe’s EAP demonstrator. I didn’t get to see EAP until I got to Warton where I wasn’t able to photograph it!

Scan 2-1535.jpgHere are some shots of the Rafale A. It was originally powered by GE F404 engines although later one was swapped for the M88 that would power the production Rafale. The first Rafale C was rolled out in an all black paint scheme which made it look very cool. The size difference is not immediately obvious but a number of detail design changes were incorporated too including lots of sensors required for an operational type rather than the demonstrator. The wing planform was also altered slightly based on the experience gained with the demonstrator. I understand that, when the aircraft was retired, it went to the Museum at le Bourget in Paris.

Westland Black Hawk

Scan 2-1611.jpgThe Sikorsky Black Hawk is a ubiquitous helicopter. They are in service around the world and Sikorsky has a second production facility getting established in Poland. What is not so well known, though, is that Westland attempted to become a license producer of the helicopter for the UK and other markets. They went as far as to build an airframe from a knocked down kit. Meanwhile, another airframe was converted to with what was then the Rolls Royce/Turbomeca RTM322 turboshaft engine for testing purpose. Together, these two airframes were demonstrated at Farnborough. The Westland derivative was not ordered by anyone and both airframes were ultimately converted to other configurations and sold on to other operators.
