"what are those words mean ?,kampfflugzeug and reiseflugzeug"

"Kampfflugzeug" today generally means all kinds of armed aircraft, in the former
german AF (WW II), the term was used for bombers (NOT fighters = "Jagdflugzeug") ,
"Reiseflugzeug" means (civil) communication aircraft/light transport

In Polish monthly " Lotnictwo " 5/2008 I've found an article concerning history of the Fairey Barracuda
built to the Air Ministry Specification No S.24/37 for diving bomber and reconnaissance aircraft.
Competitors of the Barracuda were Bristol S.24/37, Westland P.11, Supermarine type 322 Dumbo,
Blackburn B.29, Hawker S.24/37 and Folland H.21.
It made me think which of projects listed below could be Folland's design H.21 ?

Fo. 100 Bombenflugzeug Projekt 1937
Fo. 101 Jagdflugzeug Projekt 1937
Fo. 102 Kampfflugzeug Projekt 1937
Fo. 103
Fo. 104 Torpedoflugzeug Projekt 1937
Fo. 105
Fo. 106
Fo. 107 Kampfflugzeug Projekt 1938
Fo. 108 Forschungsflugzeug Projekt 1940

It is almost certain that no Fo. 101 as a fighter and no Fo. 108 as the experimental Folland Frightful.

In "The Spirit Of Hamble", by Derek N.James (many thanks, Paul !) , the Fo.145 is described as a
"twin egined VTO aircraft". As VTO usually stands for "vertical take-off", this seems to be
a VTOL version of the Gnat. Are the any other informations, anywhere ?

There are a lot of pictures, but mostly Midge and Gnat aircraft, various parts and devices built by Folland, and three photos of the Fo 108 (with Napier Sabre, Bristol Hercules and Bristol Centaurus engines). As for the drawings of the projects are as follows:

- Naval Gnat
- Gnat Mk 4
- Gnat Mk 5
- Fo 146 Advanced Trainer
- Fo 147 Fighter
- Fo 148 Fighter
- HS.1171 Trainer (Hawker Siddeley designation, but with Folland origin)

Regards,

LAW

Folland formed Folland Aircraft in June 1936 while still employed by Gloster but this was simply registering a name as it had a nominal capital of only £100. Folland then amalgamated with British Marine Aircraft in March 1937 and the company spent most of that year reorganising and refinancing (BMA having gone into voluntary liquidation) before relaunching as Folland Aircraft in December.
The designs Fo100 - Fo106, if the list and dates are correct, where therefore produced at a time when the company was in no position to build anything. I suggest that they were all conceptual/speculative designs to give the company some sort of portfolio when talking to potential investors, none appear to be related to any military or civil specification in this year. Likewise I doubt that Fo105 and Fo106 have anything to do with either C.14/38 or C.15/38; twin Aquila would certainly be underpowered for the role. Fo106a was definitely tendered to C.15/38
The twin engine design shown in a 1940 advertisement is likely to be from this early period ( see http://www.secretprojects.co.uk/forum/index.php/topic,4188.msg144336.html#msg144336) although whether it is Fo105 I cannot say, it depends whether Napier Rapiers could be install on their side, which appears doubtful.

I just spotted three errors in the Fo list in post #6.
Fo136, 137 and 138 were not aircraft; the first two were related to aero-generation, i.e. wind turbines, and the last was unspecified research for the RAE.
Here is one example of Folland's research carried out as Fo136 and Fo137

Many thanks for this correction. Apart from the interesting project, (though no aircraft), it
shows, that lists with designations can misguide. Well, who reads about the "Messerschmitt KR 200"
shouldn't expect an aircraft, too ! ;)
I ventured to edit LAWs list, was a good job nevertheless.
