Weight Data

The table below shows a summary of the weight data that I have collected for US Single Engine WWII era aircraft, from the References listed on the Introduction page.  

Caveats

1. Please note all units are in pounds and that I am still in the process of filling in and confirming some of the informationfor these tables.
2. Because References 1, 2 and 3 sometimes provide data for the same aircraft, this data has been entered in separate, adjacent columns so that the data can be compared.  Typically the weights from alternate sources may not match exactly for a number of reasons.  These differnece may represent small variations in weights of some components, changes in weights due to production line changes during the span of  when that particular aircraft model was under construction, or differences how some weights were categorized at different times.
   
3. Please also note that for some weight groups (such as the "Tail" group or the "Landing Gear" group, a further subdivions of weights may be provided for those airplanes where such data was available.  As such, rows below the "Tail" group for the "H Tail" (Horizontal Tail) and "V Tail" (Vertical Tail) are included for some aircraft.  Similarly rows below the "Landing Gear" group for "Main LG" and "Tail/Nose Aux LG" have also been added, though I may eventually separate the "Tail/Nose Aux LG" row into a separate "Nose Aux LG" and "Tail Aux LG" row to make it easier to differentiate these weights on the parametric plots being developed.
4. It currently is unclear what all is included in the "Engine Section" weight group.  It appears that this includes the the engine mounts for allaircraft as well as cowling and cooling flaps for radial engines. However for a few aircraft in the lists below such as the XP-63A a very low value of 4lb is given, while for the P-63A-10 and P-63C no value is given, leading to the suspicion that the weights of the enine mount for those aircraft may be included elsewhere in the weight estimate (such as in the "Fuselage" weight or "Engine Accessories" weight groups.
5. In the data currently collected it appears that "Fuselage" weightis equal to the sum of the "Body" and "Engine Section" weight groups. However for the weight listed in Ref [1] for several of the Brewster F2A and B339 variant aircraft it appears that the "Landing Gear'weight group has been included with the "Body" weight group. As such I have included a row for "Body + LG" in the tables below, that I intend to populate for the other aircraft types soon, to allow for a comparison between the reported weights for those Brewster Aircraft and the other aircraft in the tables.  Similarly, for the XF2A-1 listing from Ref [1] it appears that the wiht listed for the "Body" group also includes the "Enine Section" weight in addition to the "Landing Gear" weight, so a line has also been added to the table for "Body + Engine Section + LG" as well.
