WebFrom the load distributions so obtained, values of the lift curve slope were calculated and are shown in graphical form. To show the actual effect of the body, the ratio was calculated for each case and these values are also shown in graphs. An attempt is then made to give some physical reasons for this body effect. WebSep 6, 2013 · Although an increase in lift-curve slope was obtained for all aspect ratios as the ground was approached, the lift coefficient at an angle of attack of 0 deg for any given aspect ratio remained nearly constant. The experimental results were in general agreement with Wieselsberger's ground-effect theory (NACA Technical Memorandum 77).

How does the aspect ratio of a wing affect lift coefficient?

WebHere α T and β are the tailplane incidence and tab angle, a 1 is the tailplane lift curve slope, a 2 is the elevator lift curve slope and a 3 is the tab lift curve slope. It is convenient in this work to measure incidence, not relative to the chord line as is normal, but to a line parallel to the flow direction which results in zero lift.
