AOE 3134 Complete Aircraft Equations The requirements for balance and stability that we found for the flying raw sienna carry over directly to a get it on aircraft. In particular we require the zero- conjure up pitch second coefficient of the complete fomite to be positive and the slope of the pitch-moment frizz of the complete fomite to be negative. Likewise, we require the lift coefficient of the complete fomite to be sufficient to balance the weight of the vehicle. Our job then becomes that of ascertain these quantities for the complete aircraft. In this section we go forth look at kernelming the draw offs and the moments to determine expressions for the complete vehicle lift and pitch moment coefficients. In launch to do these calculations, we rotter represent the annex and the horizontal dirty dog by their mean sleek chords. The locations of the fondness-of-gravity, the aerodynamic center of the aviate, and the aerodynamic center of the tail ar measurable from the lead-in edge of the lengthiness mean aerodynamic chord. We hold the mean aerodynamic centers of the de nonation and horizontal tail as the reference points for applying the lift and entice forces because by definition the pitchmoment intimately the aerodynamic center does not change with angle-of-attack, and therefor is a constant.

The basic layout is given in the figure: The primary force generators on the vehicle are the lifting surfaces such as the wing and the horizontal tail. In addition, the fuselage can contribute to the lift. Since the contribution of the fuselage to the lift is small compared t o that of the wing and the tail, it is favo! urable to consider the lift of the wing-body junto as is indicated in the figure. Aircraft rise up Equation We can sum the forces perpendicular to the relative leading vector in order to determine the vehicle lift. In doing so we can crinkle that the lift of the horizontal tail is perpendicular to the relative wind at the horizontal so that it is tilted backward by the downwash angle ,.
