in flight is subjected to threekinds of forces: the weight, the air reaction and the pro-peller thrust. The weight is balanced by the sustaining component L,of the air reaction; the propeller thrust is balanced by thedrag-component D. The weight and the propeller thrustare forces which for… … Fig. 165. different values as there are angles of incidence. The maxi-mum value, which is assumed in computations, is, usually, y- = 0.25. Thus it will be sufficient to study the distribu-L/ tion of L, because, when this is known the horizontal stresses can immediately be calculated. Let us suppose…
