Early Aircraft Projects / Fokker parasol-wing fighters
« Last post by Arjen on Today at 04:27:11 am »
The Fokker parasol-wing fighters started with the rotary powered V.26, prototype of the E.V/D.VIII, described by Weyl as "more or less a V.13 [1918 D.VI prototype] with the bottom wing removed". The V.28 was very similar, but strengthened to use rotaries of up to twice the power of the V.26's Le Rhône. Three inline-engined were also built: V.27, V29 and V.30. The V.29 was slightly larger than the V.26/28, the V.27 slightly larger and heavier again than the V.29. I have found no image or description of the V.30 other than a line in The Complete Book of Fighters by William Green & Gordon Swanborough:
Quote
This[V.28], initially flown with a 110 hp Oberursel Ur II, was also tested with the 145 hp Ur III and 160 hp Goebel Goe III 11-cylinder rotaries. Similar airframes with different engines were the 110 hp Le Rhône-powered V 26, the V 27 and V 30 with the 195 hp Benz Bz IIIb and IIIa six-cylinder water-cooled engines respectively, and the V 29 with the 160 hp Mercedes D III.
The V.30 designation was reused for a V.26-based glider. Weyl writes the V.30 glider was originally meant to be a flying bomb.
The V.27 was modified when Fokker learned the German Army wanted an armoured single-seater for groud-attack and the protection of infantry support aircraft. As well as adding side armour, Fokker's chief designer, Reinhold Platz, added a hollow armoured spinner to protect the V.27's radiator. To cool the engine, six radial blades were attached to the spinner's armour plate to drive cooling air through the radiator. This worked so well, that Fokker wanted to use it on a new interceptor fighter that needed no armour. The modified V.27 was renamed V.37. Thijs Postma in his Fokker - bouwer van de wereldluchtvaart, Fokker b.v. 1979, writes that the F.6 (PW-5) was a development of the V.37. Green and Swanborough write that the F.VI (PW-5) was Fokker's first post-World War I fighter. To confuse matters even more, the V.40 designation was reused for what became the F.VI.
Weyl writes the V.41 was a development of the V.29. Construction of the V.41 was started in 1921 in Schwerin, Germany, but the aircraft was shipped to Amsterdam for completion. In Amsterdam, it was renamed D.X.

Had a go at rescanning some of my earlier shots from the 1990's... Any ID on the first two...?

I have modeled CUDA / AIM-120C / CUDA+Booster / Meteor generic model

With some assumption, I could compare the performance of them.


A few questions:

AIM-120C?  What about AIM-120D?


Is CUDA + Booster pretty much the same as the LREW (which uses an "up & over" trajectory to enhance range)?:

How would an air-launched version of AMRAAM-ER, or SM-6 compare?

Just curious.

1) Ya, CUDA+Booster ~ LREW, my case showed that LREW is not impressive as Meteor in range performance
    (Further improvement attempt will be conducted)
   
2) AIM-120D...... There is only a rumor, trajectory optimization and enhanced long-burn motor, to extend its range, however there is no certain way to model it

3) Other massive AAM or high speed missiles will be modeled and tested
