4. Control & Stability
Control and stability are indispensable elements within a Bachelor of Science in Aerospace Engineering, dictating the ability of an aircraft or spacecraft to maintain a desired flight path and respond effectively to pilot inputs or external disturbances. Without adequate control and inherent stability, a flight vehicle is inherently unsafe and incapable of performing its intended mission. The principles governing these aspects are thus a central focus of the curriculum.
The understanding of control and stability arises from the integration of multiple engineering disciplines within the aerospace program. These include aerodynamics, which determines the forces and moments acting on the vehicle; dynamics, which describes the vehicle’s motion in response to these forces; and control systems engineering, which designs and implements systems to modify and regulate the vehicle’s behavior. For example, the design of an aircraft’s control surfaces (ailerons, elevators, rudder) requires careful consideration of their aerodynamic effectiveness and their impact on the vehicle’s overall stability characteristics. Furthermore, modern flight control systems often incorporate sophisticated algorithms, such as proportional-integral-derivative (PID) controllers or model predictive control, to enhance stability and improve handling qualities. The development of autopilots, which enable automated flight management, represents a crucial application of control systems principles learned within this context. A practical example involves the longitudinal stability of an aircraft, where the placement of the center of gravity relative to the aerodynamic center determines the aircrafts tendency to return to its original trimmed flight condition following a disturbance. Incorrect placement can lead to instability, rendering the aircraft difficult and dangerous to fly.
In summary, control and stability are critical aspects of aerospace engineering, demanding a comprehensive understanding of aerodynamics, dynamics, and control systems.

Understanding orbital mechanics is crucial for various aerospace engineering applications, including satellite mission design, trajectory optimization, and spacecraft navigation. Erroneous calculations or a lack of understanding in this area can lead to mission failure, such as satellites entering incorrect orbits or failing to reach their intended destinations. A real-life example is the precise orbital insertion of communication satellites to ensure continuous global coverage, a process entirely dependent on the accurate application of orbital mechanics principles. The ability to predict and control the motion of these objects is not merely theoretical; it has direct and significant practical implications.
The BSAE curriculum typically incorporates orbital mechanics through dedicated coursework covering topics such as Kepler’s laws of planetary motion, orbital elements, orbit determination, orbital maneuvers (e.g., Hohmann transfer, bi-elliptic transfer), and perturbations (e.g., atmospheric drag, gravitational anomalies). Students learn to apply these concepts using analytical techniques and computational tools to solve practical problems. For instance, they may be tasked with designing a trajectory for a spacecraft to rendezvous with a specific object in orbit or calculating the propellant required for a satellite to maintain its position against the effects of atmospheric drag. Practical applications extend to the development of guidance, navigation, and control (GNC) systems for spacecraft, enabling autonomous orbital maneuvers and precise positioning. The design of satellite constellations, such as GPS or Starlink, relies heavily on orbital mechanics to ensure optimal coverage and minimal interference.
