moment of inertia data
« on: June 24, 2003, 09:18:28 AM »
well i was doing work on my lit search and i came across some moment of inertia data in a paper from 1942. unfortunately the planes arent named but i figure you guys could figure out what planes they are based on length/span/gross weight. heres a sample

Airplane#/Gross Weight/Span(ft)/Length(ft)/Rx/Ry/Rz (radius of gyration)

1/5066/35.0/26.0/.208/.358/.374
2/5788/36.0/26.8/.198/.367/.360
3/5834/34.0/29.8/.200/.328/.366
4/5992/35.0/25.2/.227/.388/.385
5/6250/36.8/29.9/.240/.334/.384
6/6410/39.4/35.0/.234/.360/.404
7/6825/37.3/31.7/.172/.356/.370
8/7533/34.0/30.0/.276/.340/.425
9/8770/40.0/30.1/.205/.324/.348
10/9000/.328/37.6/.228/.332/.404
11/9121/37.1/32.6/.270/.313/.402
12/9750/40.8/38.8/.210/.342/.386
13/10,112/47.0/39.0/.226/.414/.440

can you guys figure out what planes some of those are? theres lots more but its a pain in the bellybutton typing em in.

Heya Zig,

Don't type'em all.

Just look for 41', 43' and 40'. That would be the F4U, F6F and P-47.

The P-51 is 37ft wing span and 32'3" long and might be in what you already posted as A/C # 11.

What can I do with this data BTW? What should I be looking for to tell me what exactly?

Euro birds won't be in an American list from 1942.

i meant 1952 oops. i know the report includes only british and american airplanes. plus the radii of gyration are normalized, i think i am just gonna scan the thing then let you guys take a look at it.
