Q6 Estimate The Longitudinal Stability Derivatives For A Boeing 747 diagram Shown Below With A Summary Of Mass Geometric And Acrodynamic Characteristics Included In The Table Below For A Fight Velocity Of Mach 03. Cessna172-71-v2 3602 078 nonlinear model includes stall curve. The problem statement reads Substituting the numerical values of stability derivatives obtained for the B747 in assignment 1 calculate the Phugoid and short period modes of the B747 in the flight condition of assignment 1 Resultant text file that shows the longitudinal modes of a Boeing 747. The types first test flight occurred on March 20 2011.
The problems statement reads Calculate the longitudinal and lateral aerodynamic derivatives of the Boeing 747 aircraft.

A An aircrafts compliance to the dynamic stability requirements of MIL-8785C is defined in terms of three flying quality levelsTable 76 b MIL-8785C requires that the short period mode meet both a damping ratio Table 77 and natural frequency requirementFigure 720 c It also requires that the short period natural. Table 1 The calculation results Steady State Flight Speed. DYNAMIC STABILITY 542 LateralDirectional Stability Characteristics In this section we summarize the lateraldirectional mass distribution and aerodynamic stability characteristics of a large jet transport aircraft the Boeing 747 at selected flight conditions. These parameters are used in determining of stability derivatives and transfer functions.
