    SBD dive bombing procedures

    Unfortunately I do not have a reference handy. A few years back, I had three computer failures in the space of about 8 or 9 months. One was the repository for several thousand books and articles, manuals, flight reports and such. I do remember that two of the references I used at the time were a...

    SBD dive bombing procedures

    Hello Retattack, A few years ago I was quite interested in the SBD and some of what I found is not quite in agreement with what I have seen here. First of all, the aircraft’s attitude in the dive was very near vertical but the path it took was about 70-75 degrees from horizontal. That would...

    N1K, J2M and Ki-44 vs. 1941 and 1942 vintage Bf 109

    Hello Shortround6, In actuality, when discussing the P-36 / P-40 series of aircraft, there are at least three distinct types of airframes. There are four if the P-40Q is included, but we will ignore that one for now. The first type, is the P-36 or Hawk 75 according to the Curtiss designation...

    N1K, J2M and Ki-44 vs. 1941 and 1942 vintage Bf 109

    Gentlemen, I resolved a year or two ago not to get into these kinds of discussions because they always seem to be a rehash of the same topic without any consideration of what had already been discussed in the past. I have been involved in at least a half dozen threads on the same topic. It...

    Some observations on WW II small arms, and bit on artillery.

    The M1903A3 does have sights that are easier to use, but has a few issues as well. The elevation as you can see is not all that precise for match shooting. The barrels on many of the '03A3 are of the two groove type. The trigger guard on many of these guns is stamped steel and is not quite as...

    Some observations on WW II small arms, and bit on artillery.

    The proper name for the "rattle battle" that you described is the Infantry Trophy Match. I don't know what the course of fire was for the Springfield, but for the M14, it was (I believe) a team of 6 and usually a coach who directed the team to make sure the hits on the multiple targets was more...

    Some observations on WW II small arms, and bit on artillery.

    Hello Shortround6, It has been a very long time since I shot in Service Rifle competition, but what I remember differs a bit from what I see here. First of all, for actual "Service Rifle", the allowed guns were M1 Garand, M14 (or M1A or civilian equivalent), M16 or AR-15. The bolt guns were...

    FLYBOYJ´s new sortie

    I just found out about this sad event last Friday. I look at the listing of new and popular threads but don’t explore much anymore because of other issues I need to deal with. Regarding FlyboyJ’s favorite aircraft, read his first post on this thread. The armament he mentioned is definitely a...

    P-40 Twin

    At some point the designer has to make a decision as to whether this concept is just for looks or is supposed to be plausible. Without increasing wingspan, there isn't really any room for flaps on the trailing edge. It is even worse for the P-40. Since I do these designs as 3D models, it is...

    P-40 Twin

    T Bolt's design looks nicer. The original mock-up of a Twin P-40 looks nice. If you are building just in plastic, neither one is a problem. If you are building for a simulator, all of a sudden silly little things like locations and weights of components become an issue as to sizes of wings and...

    P-40 Twin

    If we are designing a single seat twin engine fighter from scratch either with the V-1710 or R-2800 engines, we would probably lay out the internals quite differently than we would with the idea that we are trying to keep the appearance looking somewhat like a P-40 or P-47. The question is...

    P-40 Twin

    Same idea as what I had in mind for the twin P-40. Help balance the extra few thousand pounds in the nose from the extra engine and propeller and other accessories.

    P-40 Twin

    I am certain that a fairly trim fuselage could hold sufficient fuel without the engine and turbo ducts taking up space. Think F7F Tigercat with similar engines and heavy armament close to CoG.

    P-40 Twin

    Well, what happens when there is no longer an engine in the forward section of the fuselage as in this case? What is reason for a deep fuselage then? THAT was the question.

    P-40 Twin

    A V-1710 is a reasonably appropriate engine for a twin P-40 which is what I was describing. Turbos would have been interesting but then the short exhausts would be wrong and they are a visual feature I wanted to retain. For a twin P-47, designer needs to have some excuse for the extra deep aft...
