Learning Outcomes

After successfully passing the module Flight Mechanics 2 the students have Knowledge: - flight mechanical coordinate systems, - coordinate transformations, - flight physical principles and laws of flight, - static and dynamic stability of aircraft, - controllability of aircraft, - linearized aerodynamics (derivatives of longitudinal and lateral movement). Skills: - description of aircraft movement in space with mathematical equations (flight simulation), - static stability and controllability analysis, - trim calculations, - simulation (programming) of linear and non-linear equations of motion, - linearizing nonlinear equations of motion. Competencies: - critical evaluation of static and dynamic stability of aircraft, - linearization of the aircraft movement around equilibrium states.

Content

In the module Flight Mechanics 2 the motion of the rigid aircraft in the atmosphere is described. The equations of motion in 6 degrees of freedom are set up in the body-fixed coordinate system. It is explained how aerodynamic as well as the forces and moments generated by the engine are mathematically represented for flight mechanics investigations. The equations of motion are seperated into longitudinal and lateral motion. Stationary (trimmed) and dynamic flight states are explained, as well as questions of static stability. The reactions of the aircraft to control and disturbance inputs are calculated and discussed. Contents of lecture and exercise: - coordinate systems (3D), forces and moments, - coordinate transformations and kinematic relations, - the equations of motion (6 degrees of freedom), - physical principles of the aerodynamic moments acting on the aircraft, - linearized aerodynamics (derivatives of longitudinal and lateral motion), - states of equilibrium, - trim calculations, - controllability, - stationary longitudinal movement and lateral motion, - linearization of the nonlinear equations of motion, - dynamic control and disturbance behaviour in the time domain (simulation), - static and dynamic stability.

Description of Teaching and Learning Methods

The module consists of lectures and exercises. Lecture: In the lecture the theoretical basics are taught. Exercise: In the exercises concrete tasks are worked on with all students, whereby the students try to find solutions. The teacher calculates the tasks with all students together. The simulator experiments take place in small groups. For independent work the students receive about one homework assignment per week, which is worked on individually.
