Span Load calculations for elevhtor zei o and elevates

i 10^ are ^iven in Tables 1 to IV. a erapbical estimation of

te stallin^^ character isi tcs of the revised winp i'ui tnese

evator conditions is .^iven in Figures 1 and 2.

P itching-moment calculations for the levised win,^,

evator zero, were made by the method employed in Zn-C36. For

iie estimation of full-scale results a correlation factor of 3

us applied to the calculated value ^iven iii Table 11. ns these

dilculations were made for a bare win^ a A^wof -.0/, was added

) these values for the estimation of complete rac/del characteristics.

fev3ous wind-tunnel tests of a tailless design show that this

'itchinp:-moment increment is a fair avera^re for the change in

Uchinp'-moment due to the addition of fuselage, nacelles, etc.
