A further question about "V-shaped Vokes 'dry type' air cleaners fitted in the air intake on top of the engine cowling": was this an "emergency" solution? My question is related to the idea that any efficient filtering system should be designed and built so that a pilot operated by-pass of the...

Thanks a lot Greyman: very interesting information!

Dear all, I’m looking for some information about dust/sand filters mounted on P40 models which fought in North Africa. I’m interested in sketches/drawings explaining how they were built and placed into the aircraft/engine, how they were operated by the pilot and, finally, I’d like to get...

just for the sake of completeness, a version of G55 able to load a torpedo was developed and a demo test was performed. Not a series production, but a clue that G55 had the potential for offensive missions even with the DB605A.

Thanks for your kind answer.

What is the difference between MG-FF and MG-FFM?

The question is: how many 20mm rounds for the MG 151/20 in a BF 109 F4? Some say 200, some other 150. As far as I know, the 15mm version of the MG151, had a 200 rounds provision in BF 109 F2. Moreover, 15mm and 20mm cartridges were quite similar and it seems that the same links were used for...

Interesting point. Since these safety mechanisms were already used in B24 and B17, I presume the B29 had them. As far as I know each gun in each turrett had a special " cylindrical cam" profiled to reproduce for any azimuth, the "allowed elevation". This cam inhibited gun fire whenever the gun...

Hi zjtins, interesting stuff about Warheads and Fragmentation. I'm going to study it. Thanks.

Dear DerAdlerIstGelandet if someone will kindly tell me if and where I'm wrong about my hypotesis, I'll be very happy since I'm looking for contructive discussion and criticism. If I wrote something unpolite, please tell me. Maybe I've missed some point. Thanks in advance. By the way, sorry for...

Dear tyrodtom, in spite of my limits, Politcs doesn't attract me. So, I'm sorry, but my destiny is to go on with my posts here. At least for a while. :-) Beside this, I've not understood if, after the painful reading of my last post, you think that the side move of the target and its dependence...

I agree: by 1943 it was “crystal clear” even to several Air Ministry “big shots” that 20mm or heavier cannons had to be considered for effectively intercepting heavy bombers. Just a little bit too late :-). Moreover the effective range of high muzzle velocity cannon shell had the advantage to...

Interesting considerations. Thanks. Beside the availability vs unavailability factor, I think people could have been concerned about the gun stoppage scenario: a severe drawback for the single cannon option. Another point is about the effectiveness of explosive shells. What happens to the...
